31 WSAA Product Appraisal The manufacturing standards EN 545 and EN 598 used for the vonroll DI pipes have similar performance requirements to the DI pipe manufactured to AS/NZS 2280 where testing of dimensions, mechanical properties, joint performance and pressure testing are all performed on the pipes during manufacture. The ductile iron has equivalent mechanical properties to AS/NZS 2280 i.e. minimum tensile strength of 420 MPa and minimum elongation of 10%. As part of agreement no dated between the client vonroll hydro (Suisse) ltd and the MPA NRW (Third party certification body) audits are conducted yearly at their factory in line with Technical test specifications; DVGW GW , DIN EN 545:2010 and DIN EN 598:2007. vonroll has submitted an English translation of MPA NRW annual audit report no for DUCPUR and ECOPUR to EN 545 conducted on 16 th and 17 th of April In addition, vonroll has submitted MPA NRW s 2015 annual audit report no for DUCPUR and ECOPUR to EN 545 and report no for GEOPUR to EN 598, in German. The audits were conducted on 15 th and 16 th of April 2015 and reports were issued on 28 th April 2015 in German language. By the annual visit, MPA NRW looks at three different executions of the pipes and associated fittings, simultaneously. The certification from MPV NRW is accepted as sufficient conformance requirements for the DI pipes and fittings. In addition an onsite review of the manufacturers testing data and the process control also provide sufficient information to demonstrate compliance with both standards EN 545 and EN 598. WSAA has sighted the above MPA NRW annual audit reports and saved in the folder Type tests and audit reports for vonroll DI pipes vonroll have a number of audit reports on DUCPUR, ECOPUR and GEOPUR but the content is almost the same. By the annual audit, MPA NRW checks the routine tests in the production as wall thickness, lining, coating, mechanical characteristics of the material, dimensions, etc. The type tests do not fall under the scrutiny of the annual audit because they should be renewed only in case of a new development (i.e. new connection system, change in material or design etc.). vonroll did a comprehensive type tests in accordance with EN 545 and EN 598 few years ago and the results are still valid. The type tests for GEOPUR DI pipe to EN 598 is similar to those of DUCPUR and ECOPUR DI pipes to EN 545. vonroll has submitted full report on type tests conducted for GEOPUR DI pipe which was recognized by the MPA NRW for issuing the third party product certification to EN 598. vonroll has also submitted MPA NRW audit report for GEOPUR DI pipe to EN 598 but it is in German. The type tests and audit reports associated with EN 598 have been sighted by WSAA and saved in folder. As these documents are treated as Commercial-in-Confidence, anyone need access should obtain the consent of the supplier Reece. Complies with Performance type test requirements Pressure ratings The pressure rating of ductile iron pipes and fittings in EN 545 depends on: a) Nominal size b) Class designation (pipes) - see Section below c) Joint type d) casting type (pipe / fittings)

32 WSAA Product Appraisal Pipe class designation The previous standard EN 545:2006 defined the classification of pipe and fittings, not related to pressure rating but instead to coefficient K" which when substituted in the following formula specifies the minimum wall thickness for various nominal diameters with an absolute minimum thickness of 6 mm for pipes and 7 mm for fittings. e = K ( DN) Where e is the nominal wall thickness, in millimetres: DN is the coefficient used for the determination of the thickness. It is selected from a se ries of whole numbers 8, 9, 10, 11, 12. The latest standard EN 545:2010 against which vonroll DI pipes (DUCPUR and ECOPUR ) for water supply applications are manufactured, defined the pipe classification in Clause 3.21 as follows: The pressure class of a component is defined by a combination of its structural performance and the performance of its non-restrained flexible joint. Restrained joints may reduce the PFA; in this case the PFA shall be declared by the manufacturer. Pressure class (C) - alphanumerical designation of a family of components, including their joints, relating to their operating pressures as verified by all the performance tests described in this standard, which includes the letter C followed by a dimensionless number equal to the maximum PFA in bars of the family of components. As per Annex A of EN 545:2010, the maximum values of PFA, PMA and PEA are calculated as follows: a) PFA = (20 x e min x R m) / (D x S F) Where E min is the minimum pipe wall thickness, in millimetres D is the mean pipe diameter (DE e min), in millimetres DE is the nominal pipe external diameter, in millimetres R m is the minimum tensile strength of ductile iron, in MPa (R m = 420 MPA) S F is a safety factor of 3 The maximum PFA of a pipe is equal to its class number, e.g. PFA 40 for a class 40 pipe. b) PMA: as PFA, but with S F = 2.5; therefore: PMA = 1.2 x PFA c) PEA = PMA + 5 bar Pipe Classes for Water Supply Application Pipe classes for water supplies is in accordance with EN 545:2010 and ISO 2531:2009 standards a) Pipes with push-in sockets: Pressure Class C / Thickness Class K9 b) Pipes with flanges: K12 standard The pressure performance capability of DI pipes and fittings for water supply to EN 545:2010 is shown in Table 2.

Allowable operating pressures for DI pipelines will be dependent upon the rating of elastomeric seals, flanges and appurtenances. NOTE: Applicable limits, which may not permit the full use of the pressure ranges as stated in Table 6 in an installed pipe, must be taken into consideration. For example: - Operation at the PFA and PMA values given in Table 6 for socket pipes can be limited by the lower pressure range of other pipeline components, e.g. flange pieces (Table 8), certain types of Y-fittings and certain types of moveable connections. - The water pressure test in pits with the high PEA values given in Table 6 can be limited due to the type and structure of the anchoring system of the pipe and/or the moveable connections.

This lining is applied in the vonroll factory.

40 WSAA Product Appraisal External coating Internal lining Socket end FIGURE 20: INTERNAL LINING OF ECOPUR, DUCPUR AND GEOPUR PIPES The polyurethane is composed of a two component resin. It s three-dimensionally linked molecular structure gives its mechanical stability. Polyurethane is a thermosetting plastic with no solvents. Specific details of the polyurethane characteristics are shown in the vonroll Catalogue. Each pipe is being grit, blasted twice and pre-heated before lining in order to obtain perfect adhesion and curing. The smooth surface and the equal distribution of the polyurethane are achieved by keeping the pipe in rotation during lining and coating. The interior of the socket is fully protected with polyurethane for ECOPUR and GEOPUR and with bitumen for DUCPUR. The socket of the DUCPUR pipes can be also lined by polyurethane. The thickness of the polyurethane lining shall be as follows: TABLE 14: POLYURETHANE LINING THICKNESS DN Mean value Thickness (mm) Minimum value Socket End: The internal surface of the socket end is lined with polyurethane.

Result Complies External Coatings Polyurethane coating for ECOPUR ductile iron pipes The coating of the pipes consists of a factory applied polyurethane coating. Each pipe i s being blasted and pre-heated before coating in order to obtain perfect adhesion and curing in accordance with EN DI pipes External Polyurethane coating requirements and test methods. The thickness of the polyurethane is nominal 900 microns with a minimum of 700 microns. The entire barrel included of the spigot end is coated with polyurethane. Minor coating damage (during delivery etc.) can be repaired with an easy to use dual pack cartridge which ensures the exact dosage of resin/hardener components. See vonroll Products Manual Zinc and finishing layer for DUCPUR and GEOPUR DI pipes The DUCPUR and GEOPUR DI pipes are internally lined with a Polyurethane (PUR) but are externally protected with zinc coating in accordance with ISO Ductile iron pipes - External zinc-based coating - Part 2 : Rich zinc paint with finishing layer. vonroll hydro applies the coating at a minimum of 220 g/m 2 zinc layer as prescribed in EN 545 for DUCPUR and at a minimum of 150 g/m 2 as prescribed in EN 598 for GEOPUR. The zinc coating is applied to the substrate of the ductile iron pipe by spraying of paint reach of zinc (min. 90%). DUCPUR ductile iron pipes have a black bituminous paint applied as a finishing layer to a minimum thickness of 70 μm. GEOPUR ductile iron pipes have a red brown bituminous paint applied as a finishing layer to a minimum thickness of 70 μm. The polyurethane lining is applied only in the pipe barrel for the DUCPUR. The socket is lined with bitumen. The socket of the GEOPUR is lined with polyurethane. The application of zinc coating enhances the external corrosion protection of the pipe and fittings in buried applications. Zinc coating has not historically been widely utilised on ductile iron pipes in Australia, however zinc based corrosion protection systems have been used in Europe for more than 60 years. The application of this additional corrosion protection is considered to be acceptable and beneficial to the performance of the pipe. In many soil conditions it is possible to install zinc-coated pipes without polyethylene sleeving Polyethylene sleeving Most Australian Water agencies specify polyethylene sleeving of ductile iron pipes as a means of corrosion protection. Polyethylene sleeving provides corrosion protection in aggressive soils by creating a passive uniform environment around the pipe and limiting oxygen exposure. Loose PE sleeving is installed on site on ductile iron pipelines in the form of a tubular film. Cut lengths are slipped over the pipe, overlapped and wrapped up tight before securing in place with bands and plastic adhesive tape. Polyethylene sleeving should be installed in accordance with AS 3681: Guidelines for the application of polyethylene sleeving to ductile iron pipeline. As the sleeving is the primary corrosion barrier, care needs to be exercised during installation to prevent damage. Only accredited pipe layers trained in the application of sleeving should be employed. ECOPUR DI pipe does not need the sleeving because of its polyurethane external coating and DUCPUR and GEOPUR DI pipes with its zinc/bitumen coating only requires sleeving where the soil conditions are known to be corrosive to ductile iron.

Pipes bundles have wooden supports and spacers and are restrained with plastic strapping (See Figures 26, 27 & 28). FIGURE 26: PLASTIC STRAPPING FIGURE 27: WOODEN SUPPORTS FIGURE 28: SPACERS The normal method of transporting vonroll ductile iron pipes is as follows: DN 80 to DN 300 Socket / Spigot DI pipes are delivered in bundles (packs). Pipes larger than DN 300 are delivered as single pipes. vonroll DI pipe bundles are covered with UV protective film. This covering should only be opened when necessary and should be closed again afterwards. Each pipe is sealed on socket and spigot end with caps. Experience to date shows there has been very little damage to the pipe coating during transport from Switzerland. Only wide synthetic lifting belt should be used when loading and unloading the pipes to prevent damage to the polyurethane coating. Piping components made of elastomers, e.g. EPDM jointing rings, can be affected by heat, light, ozone, dampness, solvents and storage under tension. For this reason particular care must be taken with the storage and handling of these items. Precautions include: Max temperature 25 C and Minimum -10 C Keep away from UV light Relative Humidity under 65% No ozone exposure e.g. keep away from electric motors

The longer-term information focused on the polyurethane coating performance and was obtained overseas. The shorter-term experiences of local water Agencies were obtained to gauge installation practices Long Term The polyurethane lined pipe and more recently the lined and coated pipe has been used widely by Zürich Water in Switzerland since the product was first developed in Some problems were encountered with the first generation internal lining that resulted in a change of coating formulation. The original polyurethane was of the flexible type and when this showed signs of blistering, further research was carried out which led to the development of a rigid polyurethane version. This later generation of coating has much higher adhesion strength to the ductile iron that provides superior performance. The change to rigid polyurethane was made in A section of first generation pipe was inspected which had 20 years service and while this showed considerable blistering, minimal rusting of the substrate was apparent. It was reported that similar aged rigid polyurethane pipe performed very well without any blistering or deterioration. Zürich Water have also carried out controlled tests since 1990 to monitor the performance of the ECOPUR and DUCPUR pipes in different soil types and at the end of 1998 they are satisfied with the results.

49 WSAA Product Appraisal Short Term Locally, City West Water in Melbourne has been using both ECOPUR and DUCPUR pipes for approximately 16 years. Feedback from the construction crews has been positive and no major problems have been encountered. It was reported that it was easier to lay the pipe as the jointing pressures being quite low. The pipe was also easier to handle and there did not seem to be a major problem in external coating damage to the ECOPUR during normal handling. On a precautionary note, a greater input into the supply logistics is required to ensure that the correct fittings and adaptor rings are available and supplied. The repair coating used to make good cut ends of the pipe also took considerable time to cure but this was usually avoided by better planning. Refer to Appendix H for site photographs of vonroll ECOPUR ductile iron pipes used at City West Water in Melbourne 15 AVAILABILITY OF PRODUCTS Reece is a national supplier of pipes, fittings and ancillary items for the water industry around Australia. Reece have large stock holdings of vonroll products in their local warehouses and a major central warehouse with overnight deliveries to all states. The office locations with contact details are shown in Appendix F as follows: Head Office is located in Victoria at: Reece Australia Limited, 118 Burwood Highway, Burwood VIC 3125; Tel: ; Website: 16 REPAIRS TO POLYURETHANE COATING Users should be mindful to watch for external damage to the polyurethane coating of ECOPUR DI pipe as it may be difficult to detect damage in a black coating on a black pipe. One product is available for the repair of the polyurethane coating and lining. Repairs are recommended when ECOPUR pipes are cut or damaged. The repair material is an epoxy repair kit. The epoxy repair kit is used for repairs of smaller surfaces, e.g. cut ends up to DN 300 and repairs with area up to approximately 100 Sqcm. Either repair kit can be used on the interior green lining or exterior black coating. Similarly where cut or drilled holes are made in the pipe, repairs should be made or if that procedure is carried out under pressure, an anti-tuberculation insert should be provided to prevent blockage of the outlet. As stated in Section 7.3, where possible the Pre-Tap Connectors be utilised in providing new services instead of drilling holes on the pipe to provide services using ball valves / ferrules and tapping bands. Zürich Water is one the long term users of vonroll DI pipes. Feedback from Zurich Water indicated that they no longer repair cut ends as the level of corrosion is minimal and is unlikely to constitute a future failure point in pressure mains. 17 DISCUSSION vonroll has pioneered polyurethane materials for use as a pipe lining and coating over the last 42 years. During this time the product has been used extensively in some European, African and Middle East markets. The direct information from one of the larger and longest users, Zürich Water, has been positive with excellent performance reported. The polyurethane coatings are now being adopted by some pipe manufacturers in the USA and several recent technical papers have provided testing data of various pipe linings. While the data does not provide any details of long-term performance the information does provide data which demonstrates superior physical properties of polyurethane coatings compared to other more conventional linings. This information from users and current trends in other parts of the world give confidence that the vonroll product will provide a long life pipe system.

50 WSAA Product Appraisal One of the advantages of this pipe is the relative inertness of the lining that has no adve rse effect on the water quality. Additional corrosion protection is not required with the ECOPUR pipe. The literature claims that the ECOPUR pipe can be directly backfilled and buried with the original trench excavation material. The polyurethane coating has high levels of adhesion and is reported to have high resistance to damage and undercutting. If the external coating is damaged, corrosion will occur and depending on the extent of damage a perforation may occur in the longer term. While in some cases the use of trench excavation material could be used, a number of risks emerge if this practice is adopted. Increases the risk to damage if stony or rocky material is used up to 60 mm size. Some trench excavation material, bigger than 100 mm, would be very difficult if not impossible to compact which would be a problem under a carriageway. In general it is felt that for maximum protection, selected bedding and backfills should be utilised to minimise damage to the external coating. It is recommended to use bedding material as sand or gravel up to 32 mm size. In a similar context the DUCPUR pipe with a combined external coating of zinc and bitumen is claimed to overcome the need to use loose fit polyethylene sleeving in low corrosivity soils. The use of the zinc/bitumen external coating is widely used in some parts of the world without sleeving and specific criteria has been set down where sleeving is and isn t required. Similar criteria can be used for ductile iron with a bitumen coating but the majority of Australian Water agencies have adopted the policy of full sleeving of all ductile iron pipe with zinc/bitumen coating. It is well documented that the application of a zinc coating will not detract from the performance and in some environments there are definite improvements to the performance of the pipe. Unless the environment is known to be low corrosivity, the use of the sleeving in conjunction with the DUCPUR pipe is recommended. Like all pipes, it is better to avoid the cutting of holes which can act as points of corrosion or stress failures so it is felt that the use of pre tapped connector fittings for the connection of services should be adopted in the first instance to minimise this effect. Where holes have to be cut the use of plastic inserts is recommended to prevent the growth of rust tubercles that can reduce flow in the longer term. For the tapping of the vonroll ECOPUR and DUCPUR DI pipes, there will be no damage to the coating and lining if the right equipment/device is used. Tapping with saddle under pressure is always possible for the vonroll DI pipes up to and including DN 400. If copper services are used in conjunction with these pipes it is essential to use insulated fittings to prevent galvanic attack of the ductile iron. 18 OUTCOMES OF EXPERT PANEL PRODUCT REVIEW <Enter text here> 19 LIFE EXPECTANCY Operational experience with cast iron pipe in Australia has shown a life expectancy of over 100 years. The new generation of ductile iron pipes with the specialist coatings can only be expected to extend this life even further. On this basis an operational pipe life of well over 100 years can be expected. The manufacturing standards used for the pipe have similar performance requirements to AS/NZS 2280 in that testing of dimensions, mechanical properties, joint performance and pressure testing are all performed on the pipes during manufacture. The ductile iron has equivalent mechanical properties to AS/NZS 2280 i.e. Minimum tensile strength of 420 MPa and Minimum elongation of 10%. The certification from MPA NRW confirms conformity to the relevant EN standards; i.e. EN 545 and EN 598.

51 WSAA Product Appraisal vonroll have been manufacturing centrifugally cast iron pipes since In 1965 the pipe material changed from grey cast iron to ductile iron and in the early 1970 s the internal coating was changed to polyurethane. vonroll have supplied approximately 60-70% of all pipe in Switzerland, most of which has been lined with polyurethane since its introduction. Zürich Water has been a major user and was involved in the initial development of the polyurethane lining and they have been monitoring the pipe s performance since that time. They have exhumed some early polyurethane coated installations and the coating was reported as being as good as when it was installed. 20 FUTURE WORKS Within six months of publication of this appraisal report, vonroll hydro has to provide the following document: a) Hultec Europe (France) s DVGW Cert GmbH s Product Certification for Rubber Gasket TYTON EPDM for DIN EN 681-1, DVGW W270, BGA KTW and DVGW VP 545, as the current one expired on 16 February DISCLAIMER This Product Appraisal Report (Report) is issued by the Water Services Association of Australia Limited on the understanding that: This Report applies to the product(s) as submitted.

53 WSAA Product Appraisal APPENDIX A GERMAN ACCREDITATION SYSTEM German Accreditation System for Testing (DAP) is a member of the German Accreditation Council (DAR), the European co-operation for Accreditation (EA), the International Laboratory Accreditation Co-operation (ILAC), the International Accreditation Forum (IAF) and their Multilateral Agreements for Recognition (MLA and MRA), a member of the European Federation of National Associations of Measurement, Testing and Analytical Laboratories (EUROLAB), the European Organisation for Quality (EOQ), the German Society for Quality (DGQ) and the German Institute for Standardization (DIN). DAP is a legally independent accreditation bodies in the German. It is responsible for the accreditation of testing and research laboratories, of certification bodies and of inspection bodies in the voluntary area. DAP s primary activity is the accreditation of material testing and chemical analytical bodies in Germany. The European Series of Standards DIN EN 45000, the DIN EN ISO/IEC and the ISO/IEC-Guides are the basis for the accreditation. The equivalence of the accreditation systems of many countries in Europe is determined through the European co-operation for Accreditation (EA) Multilateral Mutual Recognition Agreements (MLA), which are signed for accreditation programmes of specific conformity assessment activities, such as testing laboratories and product certification bodies. Signatories to the EA MLAs recognise mutually each other's accreditation systems as being equivalent to their own. Bilateral agreements between EA and other accreditation bodies outside Europe have also been signed, thereby facilitating the mutual recognition of these accreditation systems outside of EA. Membership of the EA MLA is achieved by successfully undergoing a system of peer evaluations. DAP is a signatory to the EA MLA for testing laboratories and product certification bodies since In addition, DAP also signed (through DAR) the Mutual Recognition Arrangement of International Laboratory Accreditation Cooperation (ILAC) of International Laboratory Accreditation Cooperation (ILAC) on and on the Mutual Recognition Arrangement of International Accreditation Forum (IAF). These Agreements and the Arrangement would in general form the prerequisite for the recognition of test reports and certificates issued by DAP conformity assessment bodies (testing laboratories, certification bodies for products and inspection bodies) in the respective countries of ILAC signatories.
