This European Standard shall be given the status of a national st
16、andard, either by publication of an identical text or by endorsement, at the latest by November 2012, and conflicting national standards shall be withdrawn at the latest by November 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent ri
17、ghts. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14909:2006. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requir
18、ements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. The main technical changes are: the resistance to low temperature is only tested with the upper side in tension; the minimum tolerance for the water vapour transmis
19、sion is fixed; the rules for mounting and fixing for reaction of fire testing are improved and the variation of products where a result apply are fixed; for FPC the indirect testing as in other TC 254 standards is introduced.

DIN EN 14909:2012-07 EN 14909:2012 (E) 5 Introduction 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 def
22、lect 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 parapet walls to protect the inside of the building from water moving down from above. They should be designed in conjunction with flashings and sh
23、eets for waterproofing, including roofing sheets and damp proof sheets, to ensure a continuous barrier and should deflect water to the exterior of a building so that it can drain away safely. DIN EN 14909:2012-07 EN 14909:2012 (E) 6 1 Scope This European Standard specifies the characteristics of fle
24、xible sheets of plastics and rubber intended for use as damp proof courses for buildings. It specifies the requirements and test methods and provides for the evaluation of conformity of the products with the requirements of this European Standard. This European Standard does not cover related produc
25、ts such as preformed cavity trays, coping and flashings. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

39、ion The types of damp proof sheets covered by this European Standard are designated as follows: TYPE A damp proof course; TYPE V damp proof course ventilating or draining. 5 Product characteristics 5.1 General 5.1.1 Where a tolerance is limited by this European Standard it does not have to be declar
40、ed by the manufacturer. 5.1.2 When tested for purposes other than initial type testing or factory production control, the tests to determine product characteristics indicated in this standard shall be started within one month of delivery of the product from the manufacturer. 5.2 Deviation from test
41、sample dimensions Where the contours of the product make it impossible to obtain a test sample of 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 sa
42、me thickness as the finished product. Any such deviations from the test method shall be recorded on 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 1850-2. 5.4 Dimensions and tolerances The length, width an
43、d straightness shall be determined in accordance with EN 1848-2. The length and width shall lie within the declared tolerance of the manufacturers declared value. The maximum deviation from straightness shall not exceed 75 mm per 10 m length or in proportion for other lengths (e.g. 37,5 mm per 5 m l
44、ength). 5.5 Thickness and mass per unit area The thickness and mass per unit area shall be determined in accordance with EN 1849-2. 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
45、 obtain a sample (see 5.2), a larger sample area shall be used and the deviation from the test method noted. Where a product is specified by thickness, the thickness shall lie within the declared tolerance of the manufacturers declared value. No single measurement shall lie outside the declared tole
