14、rd This document (EN 14967:2006) has been prepared by Technical Committee CEN/TC 254 “Flexible sheets for waterproofing”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at
15、 the latest by November 2006, and conflicting national standards shall be withdrawn at the latest by November 2006. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).
16、 For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Cz

18、n The purpose of damp proof courses is to prevent water rising up a wall from the ground, water moving from one part of a wall to another and to deflect water from an inner wall of a cavity wall construction to the exterior of the building. Damp proof courses may also be used in masonry chimneys and
19、 parapet walls to protect the inside of the building from water moving down from above. They should be designed in conjunction with flashings and sheets for waterproofing, including roofing sheets and damp proof sheets, to ensure a continuous barrier and should deflect water to the exterior of a bui
20、lding so that it can drain away safely. BS EN 14967:2006EN 14967:2006 (E) 5 1 Scope This European Standard specifies the characteristics of flexible sheets of bitumen intended for use as damp proof courses for buildings. It specifies the requirements and test methods and provides for the evaluation
21、of conformity of the products with the requirements of this European Standard. This European Standard does not cover related products such as preformed cavity trays, coping and flashings. 2 Normative references The following referenced documents are indispensable for the application of this document

30、e plane to another 3.2 waterproofing sheet factory-made flexible sheet including any carriers, facings, surface texture and/or backing 3.3 bitumen damp proof course flexible sheets of bitumen or composites based on these materials whose function is to prevent liquid water passing from one part of th
31、e wall to another. In composite sheets the bitumen is the functional component 3.4 carrier material incorporated into or onto the factory-made waterproofing sheet to ensure its stability and/or mechanical resistance 3.5 surfacing material applied to the surfaces of waterproofing sheets as an anti-st
32、icking substance on one or both surfaces of the damp proof course 3.6 manufacturers limiting value (MLV) value stated by the manufacturer to be met during testing. The manufacturers limiting value can be a minimum or a maximum value according to statements made under product characteristics of this
33、European Standard 3.7 manufacturers declared value (MDV) value declared by the manufacturer accompanied by a declared tolerance 3.8 oxidised bitumen straight run petroleum bitumen or a fluxed bitumen which has been hardened and rendered less temperature susceptible by blowing with air at high temper
34、ature with or without the use of a catalyst 3.9 elastomeric bitumen petroleum bitumen and/or oxidized bitumen modified by the addition of thermoplastic rubbers 3.10 plastomeric bitumen petroleum bitumen and/or oxidized bitumen modified by the addition of polyolefin or polyolefin copolymer compound 3

36、t types For bitumen damp proof courses there are no product types. 5 Product characteristics 5.1 General 5.1.1 Where a tolerance is limited by this European Standard it does not have to be declared by the manufacturer. 5.1.2 When tested for purposes other than initial type testing or factory product
37、ion control, the tests to determine product characteristics indicated in this European Standard shall be started within 1 month of delivery of the product from the manufacturer. 5.2 Deviation from test sample dimensions Where the contours of the product make it impossible to obtain a test sample of
38、the required dimensions, or otherwise render the test impracticable, testing may be carried out either on samples of different dimensions or if still impracticable on the equivalent flat sheet of the same thickness as the finished product. Any such deviations from the test method shall be recorded o
39、n the test report and the product data sheet. 5.3 Visible defects The product shall be free of visible defects determined in accordance with EN 1850-1. 5.4 Dimensions and tolerances The length, width and straightness shall be determined in accordance with EN 1848-1. The length and width shall be gre
40、ater than or equal to the manufacturers limiting value (MLV). The maximum deviation from straightness shall not exceed 20 mm per 10 m length, or in proportion for other lengths (e.g. 10 mm per 5 m length). 5.5 Thickness and mass per unit area The thickness and mass per unit area shall be determined
41、in accordance with EN 1849-1. Where a product is specified by mass per unit area, the mass shall lie within the declared tolerance of the manufacturers declared value. Where it is not practicable to obtain a sample (see 5.2), a larger sample area shall be used and the deviation from the test method
42、noted. If a product is specified by thickness, the thickness shall lie within the tolerance of the manufacturers declared value. No single measurement shall lie outside the declared tolerance of the manufacturers declared value. BS EN 14967:2006EN 14967:2006 (E) 8 5.6 Watertightness Watertightness s
43、hall be determined by Method A or B of EN 1928 using a pressure of 2 kPa and shall give a pass result. 5.7 Resistance to impact Resistance to impact shall be evaluated when subject to regulatory requirements, and may be evaluated when not subject to such requirements. It shall be determined in accor
44、dance with EN 12691 and the result shall be greater than or equal to the manufacturers limiting value. 5.8 Durability 5.8.1 Against artificial ageing/degradation In order to verify the artificial ageing behaviour of the product, watertightness shall be determined after exposure in accordance with EN
45、 1296 for a period of 12 weeks. The watertightness shall be determined in accordance with EN 1928 Method A or B at a pressure of 2 kPa and shall give a pass result. 5.8.2 Against chemicals Information about the chemical resistance of bitumen is given in Annex A. Where the product is likely to come i
46、nto contact with a “not stable in all cases“ substance, the resistance shall be evaluated according to EN 1847, the test parameters being declared with the result, and subsequently tested according to EN 1928, giving a pass result. NOTE Experience has shown that water has little or no effect upon th
47、e in-service performance of reinforced bitumen sheets. 5.9 Flexibility at low temperatures (pliability) The flexibility at low temperature shall be evaluated when subject to regulatory requirements, and may be evaluated when not subject to such requirements. It shall be determined in accordance with
48、 EN 1109 and shall be less than or equal to the manufacturers limiting value. NOTE This test does not give results corresponding to the application conditions in practice. Results should be used only to compare products of similar thickness and construction. 5.10 Resistance to tearing (nail shank) W
49、here required, the tear resistance (nail shank) shall be determined in accordance with EN 12310-1 and the results shall lie within the declared tolerance of the manufacturers declared value. 5.11 Joint strength Where required, the joint strength shall be determined in accordance with EN 12317-1 and the results shall lie within the declared tolerance of the manufacturers declared value. 5.12 Water vapour transmission properties Where required, the water vapour transmission properties shall be determined in accordance with E
