When the door is part of a fire- and smoke free escape route the door shall comply with class B. Method of determination The class of fire propagation according to NEN-EN shall, for both the inner as the outer side of the door, be determined by means of tests by an acknowledged laboratory. Explanation: An inner door and/or inner door frame or a similar structural component has, according to NEN-EN a certain contribution to the fire propagation on both inner and outer side, that complies with at least class D or at least class B when the door is part of a fire- and smoke free escape route Certification investigation / attest-with-product certificate The attest-with-product certificate indicates that an inner door and/or inner door frame has a contribution to fire propagation that at least complies with class D or at least Class B when the door is part of a fire- and smoke free escape route. LIMITATION OF DEVELOPMENT OF FIRE: BA- SECTION 2.13 AND BA-SECTION (OPTIONAL) Performance requirements WBDBO For the limitation of fire apply sections and of the Building Act 2003 Limiting value The limiting value for the resistance to fire penetration and flash-over (WBDBO) is determined by the resistance to the flash-over of an inner door and/or inner door frame as laid down in NEN This WBO depends on the radiation flux in the normative observation point determined in accordance with NEN In the NEN 6068 is determined that an inner door and/or inner door frame, which has a fire resistance relating to the dividing function of at least 30 minutes. is no façade opening. This also applies in case of the WBDBO requirements is 60 minutes. For a movable part in an exterior separation construction a requirement for self-closing does not apply. Method of determination In the situation that the resistance to fire penetration and flash-over of the inner door and/or inner door frames is determined, this shall be carried out in accordance with NEN Explanation: WDBDO-requirement: The resistance to fire penetration and flash-over (WDBDO) between two fire compartments, an enclosed room through which an escape route leads, a non-enclosed room of a safety staircase and between two smoke free escape routes applies a requirement in respect of the resistance to fire penetration and flash-over and shall comply with the performance requirements determined in accordance with NEN 6068.

9 Inner doors and/or inner door frames dd Page 9 of 61 Certification investigation / attest-with-product certificate The fire resistant of an inner door and/or inner door frame shall, when required, be included in the attest-with-product certificate, such as has been determined by means of tests by an acknowledged laboratory. Hereby is indicated whether it concerns the fire resistance from inside to outside, from outside to inside or in both directions. This is then at least 30 minutes and can be expressed in a multiple thereof. LIMITATION FOR THE DEVELOPMENT OF SMOKE; BA-SECTION Performance requirements, smoke density ; BA-section For the limitation of the development of smoke section of the Building Act 2003 applies. Limiting value The limiting value is class s2 for the inside of an inner door and/or inner door frame. This does not apply to a building structure, not being a building. Method of determination The class of the development of smoke in accordance with NEN-EN shall be determined by means of tests by an acknowledged laboratory. Certification investigation / attest-with-product certificate The development of smoke of the inner side of a door can be stated in the certificate as determined by means of tests by an acknowledged laboratory. The smoke class belongs at least to smoke class s2. LIMITATION FOR THE MOVEMENT OF SMOKE ; BA-SECTION Performance requierements; resistance to the movement of smoke For the resistance to the movement of smoke applies section of the Building Act Limiting value The limiting value is set at 30 minutes. This applies when the inner door and/or inner door frame has been included in a smoke separation. This limiting value does not apply to another application or to a building construction that is not a building. Method of determination The class of the development of smoke is determined by NEN Certification investigation / attest-with-product certificate The resistance to the smoke penetration can be laid down in the certificate. This amounts to at least 30 minutes. BURGLARY RESISTANCE BA-SECTION (OPTIONAL) Performance requirements, burglary resistance; BA-section Section of the Building Act 2003 applies to burglary resistance. Limiting value When the inner door is intended for a walled-in entrance to a dwelling it shall have, together with the frame, a resistance class 2 for burglary resistance. Method of determination A walled-in entrance door to a dwelling is per definition at an accessible place as meant in NEN The walled-in entrance door to a dwelling shall therefor be tested in accordance with NEN 5096.

10 Inner doors and/or inner door frames dd Page 10 of 61 Explanation: The resistance class 2 is determined in accordance with NEN It applies to: the mechanical strength of the door hung in the frame that has been secured to the connecting construction components, including the securing of the section filling of glass and the resistance to other section filling than glass; the application of insulating double glass or of glass with resistance class 3, determined in accordance with NEN-EN 356; the lock possibilities of at least one bolt of a glazed door, unless glass has been applied with resistance class 4, determined in accordance with NEN-EN 356; the corrosion resistance of hinges, locks and door furniture; and burglar resistant properties of the cylinders. Certification investigation / attest-with-product certificate The resistance class of the walled-in entrance door to a dwelling against burglary is optionally mentioned in the certificate, as determined by means of tests by an acknowledged laboratory. 4.2 Health regulations PROTECTION AGAINST EXTERIOR NOISE; BA-SECTION 3.1 (OPTIONAL) Performance requirements, Characteristic protection against noise; BA-section 3.2 and 3.3 For a limited number of functions for the protection against noise from outside noise, sections 3.2 and 3.3 of the Building Act 2003 apply. Limiting value The performance requirement applies to a limited number of functions of use. The limiting value for the protection of noise from outside, expressed as characteristic noise proof barrier, is, when applicable, determined by the noise load as a result of industrial noise, road noise, railway noise and aviation noise on the one side and the limiting value in the domestic area on the other side. The value of the noise load from outside depends on the values laid down for the noise zone in the zoning plan In which the building concerned is located,, or on local circumstances. The limiting value is a domestic area respectively the domestic room is dependent on the function of use and possibly of the way in which the function of use is intended to be used for a 24 hours period. For the functions of use for which a performance requirement is given, applies that the characteristic noise barrier between the outside air and a domestic area shall be at least 20 db(a) and between the outside air and a domestic room is at least 18 db(a). For the noise barrier in respect of aviation noise applies that the characteristic noise barrier between the outside air and the domestic area in case of a noise load of more than 35 Ke, a noise barrier of at least 30 db(a). From this it can be concluded that also in the situations that the outside noise load and the noise load allowed inside, are known; only the limiting value can still be determined to which the total enveloping construction shall comply. A limiting value for a separate door cannot be determined. Method of determination The partial noise level can, for information, be measured in an authorized laboratory in a way laid down beforehand (e.g. by referring to NEN-EN ). Explanation: The method of determination applied in Building Act 2003 is a measuring method only being used in practice after realisation of the building. However in order to be able to estimate beforehand (before the application for a building permit is submitted) whether it is acceptable that the required characteristic noise barrier, when applicable, shall be present, usually use is made of the (not mentioned in the Building Act 2003) of Calculation method GGG 97 prepared by the inter- municipal work group building physics of large towns and published by Omegam in Amsterdam. In order to apply this method the partial insulation values (in 5 octave bands) for each structural component that it is important for the determination of the noise barrier.. Certification investigation The partial sound level can be mentioned in the certificate as an option, such as has been determined by means of tests by a recognized laboratory

11 Inner doors and/or inner door frames dd Page 11 of 61 NOISE CONTROL BETWEEN DOMESTIC ROOMS WITH THE SAME FUNCTION OF USE; BA- SECTION Performance requirements, (whether or not characteristic) insolation-index; BA-section For the characteristic insulation-index for aerial noise and the insulation-index for contact noise for noise transfer from a closed room to another domestic area shall comply with the performance requirements as given in BA-section Limiting value The performance requirement applies to a limited number of noise functions. The limiting value for protection against noise between domestic places of the same functions of use, expressed as characteristic noise proof barrier, is, when applicable, determined by the noise load as a result of noise from another domestic area. The limiting value in a domestic area respectively the domestic room depends on the functions of use and possibly of the extent in which the function of use is intended in order to be used in the 24 hours period. A limiting value for a separate door can not be determined. Method of determination The value is determined in accordance with NEN Certification investigation / attest-with-product certificate The attest-with-product certificate states the contribution to the characteristic insulation-index for aerial noise and the contribution to the insulation index for contact noise. NOISE CONTROL BETWEEN ROOM WITH DIFFERENT FUNCTIONS OF USE ; BA SECTION Performance requirements, (whether or not characteristic) insulation-index; BA- section For the characteristic insulation index for aerial noise and the insulation index for contact noise of an enclosed room to another domestic area have to comply with the performance requirements as given in BA-section Limiting value The performance requirement applies to a limited number of functions of use. The limiting value for protection against noise between domestic areas of various functions of use, expressed as characteristic noise proof barrier, is, when applicable, determined by the noise load as a result of noise from other domestic areas. The limiting value is a domestic area respectively the domestic room depends on the function of use and possibly of the extent in which the function of use is intended to be used in a 24 hours period. A limiting value for a separate door cannot be determined. Method of determination The value is calculated in accordance with NEN Certification investigation / attest-with-product certificate Control whether the performances given, determined in accordance with NEN 5077, are correct. The attest-with-product certificate can mention for the examples of application the contribution to the insulation index for aerial noise and to the contribution to the insulation index for contact noise for noise transmission. These have minimum values as given in BA table RESTRICTION ON THE USE OF HARMFUL MATERIALS; BA-SECTION 3.15 (OPTIONAL)

Method of determination It should be stated when asbestos is present in the door. Certification investigation / attest-with-product certificate Check whether the materials stated comply with the regulations. The attest-with-product certificate states t hat the materials applied comply with the regulations given by Ministerial Regulation as meant in BA-section Regulations from the utility point of view FREE PASSAGE; BA-SECTION 4.3 (OPTIONAL) Performance requirements, free passage ; BA-section 4.11 member 1 and BB-section 4.11 member 2 Section 4.11, members 1 and 2 of Building Act 2003 apply for the free passage. Limiting value The free passage of an entrance of a building shall be at least 0,85 m x 2,3 m. This does not apply to a light industrial function or another function of use. Method of determination Which free passage is present depends on the form of the dimensions of the door, the form of the frame in which the door is placed and the turning direction of the door. It is also important in which position (under 90 or 180 ) the door is inspected. Explanation When applied in the existing building the dimensions of inner doors and/or inner door frames are dependent on the building frame present and can deviate from the required dimensions. Certification investigation / attest-with-product certificate In the certificate can be indicated if and under what conditions the free passage of 0,85 m x 2,3 m can be present. There is also indicated which free width can be present under what circumstances. ACCESSABILITY; BA-SECTION 4.4 (OPTIONAL) Performance requirements, height of threshold; BA-section 4.17 member 1, BA-section 4.17 member 2 and BA-section 4.17 member 3 For a difference in height of a floor at the place of an entrance to a domestic function or accessibility sector with the floor of a joint traffic space or the joining ground shall comply with the performance requirements as given in BA-section 4.17 member 1, BA-section 4.17 member 2 and BA-section 4.17 member 3.

Certification investigation / attest-with-product certificate The attest-with-product certificate states the heat transmission coefficient of inner doors as determined by means of tests by an acknowledged laboratory LIMITATION OF AIR PERMEABILITY; BA-SECTION 5.2 (OPTIONAL) Performance requirements, Flow of air volume; BA-section (informative) For the limitation of the air permeability applies section of the Building Act Limiting value That part of a building within a thermal shell (in which the domestic areas, toilet- and bathing block are present) may not have a greater flow of air volume than 0,2 m³/s. This does not apply to a heated industrial function. Dit geldt niet voor een ten behoeve van het verblijf verwarmde industriefunctie, een niet-verwarmde logiesfunctie of een overige gebruiksfunctie. Method of determination The method of determination applied in the Building Act 2003 is a measuring method that can only be applied after realisation of the building, in accordance with NEN There is no method available to determine the contribution of the individual inner door. Explanation (optional): In order to estimate beforehand (before the application for a building permit has been submitted) whether it is acceptable that the highest allowable air permeability (or the value stated in the energy performing calculation) is not exceeded, an estimation of the air permeability of a building can be determined. Hereby is calculated how much air shall go between all partial seams and chinks. These quantities are subsequently added together. There is, however, no informal recognized method available in which way this has to be done. A result of this is that when applying this also shall be indicated in which way the partial quantities can be determined (measured or calculated). Certification investigation / attest-with-product certificate The air permeability can be stated in the certificate in an informative way according to one of the calculations included in the BRL or as determined by means of tests by an authorized laboratory.
