56 Page 18 from 20 Test report No from 10 January 2008 Evaluation The product TREFF GUARD Parquet Coatings (hardened) was examined on behalf of Treffert Coatings GmbH (emission test and content analysis). Preliminary remarks: The tested product was applied to a carrier plate / derived timber product ( ) by the manufacturer. The hardened sample has been examined in an emission test chamber. In the test report the emissions of the applied product ( ) are compared with the emissions of the carrier plate. Hereby only that volatile organic compounds of the carrier plate were listed those were also emitted by the coated sample. The period between the application of the carrier plate with the coating system and the consignment of the sample to the eco-institut was about 4 weeks. For this reason the recommendation for the testing of a freshly produced sample could not be kept. The results in the test report are evaluated as follows: 1. Volatile organic compounds (VOC) Carcinogenic, mutagenic and teratogenic volatile organic compounds (CMT-VOC, categories 1 and 2) were not detectable. The total volatile organic compounds (TVOC) are 23 µg/m 28 days after loading the test chamber. It is evaluated as very insignificant. Very volatile organic compounds and semi volatile organic compounds were detectable only in low concentrations 28 days after loading the test chamber. 2. Formaldehyde The formaldehyde emission is 9 µg/m (0,007 ppm) 28 days after loading of the test chamber. The separately tested carrier plate shows slightly raised formaldehyde emission (22 µg/m, 0,018 ppm), therefore it can be assumed that the formaldehyde value of the testing coating system on carrier plate results from the carrier plate. 3. Odor The odor of the product was described as not perceptible to perceptible, not bothering. 4. Organic halogens AOX (absorbable organic bound halogens) as well as EOX (extractable organic bound halogens) were not detectable. 5. Phthalates Di-iso-nonyophthalates (DINP) and Di-iso-decylphthalates (DIDP) were detectable in low, hygienic harmless concentrations. Remark: The test result referred to the submitted test sample exclusivly. The validity of the report will end at any alternation of material composition or in manufacturing process.

57 Page 19 from 20 Test report No from 10 January Organotin compounds Only traces of organotin compounds were detectable. 7. Evaluation summary The product TREFF GUARD Parquet Coatings (hardened) fulfills the criteria recommended by the eco-institut-label Painting and coating materials (status: September 2007). Although the detected emissions are low, it is not possible to compare with the limit values of the eco-institut-label, because the accepted period between the application of the carrier plate and the measurement (requirement: freshly produced sample) was exceeded considerably.

58 Page 20 from 20 Test report No from 10 January 2008 Appendix Explanation to the Specific Emission Rate SER SER stands for specific emission rate, which gives information about the emission of volatile organic compounds (VOC) in correspondence to the material unit and time (H) The material unit for SER can be: l = length (m) a = area (m ) v = volume (m ) u = piece represents the emission of the length represents the emission of the area represents the emission of the volume represents the emission of the complete unity The different dimensions for SER are: length specific SER l in µg/m h area specific SER a in µg/m h volume specific SER v in µg/m h unit specific SER u in µg/u h Hence SER presents a product specific rate describing the mass of a volatile organic compound emitted from a product per unit time at a given time from the start of the test. For the transformation the calculated concentration of VOC (C in µg/m ) in the testing chamber is multiplied with the specific air flow rate (q in m /h m ) SER = q C Without the detail of the SER chamber measurement results are comparable from different sources only when the measurings were carried out at the same specific air flow rate q. According to possibility measuring conditions are established q = 1, so this is to equate the concentration C with SER in the examining chamber. The result can be indicated instead of microgram (µg) also in milligram (mg), 1000 µg = 1 mg. Remark: The test result referred to the submitted test sample exclusivly. The validity of the report will end at any alternation of material composition or in manufacturing process. Publishing in parts requires authorisation.
