Amendments This standard differs from DIN EN 494:2013-01 as follows: a) The standard has been brought in
9、 line with the new EU Construction Products Regulation (CPR) by the addition of a new Annex ZA as well as Clause 6, “Assessment and verification of constancy of performance AVCP”.

30、This document supersedes !EN 494:2012“. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. !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
31、ements of the EU Construction Products Regulation 305/2011. For relationship with the EU Regulation 305/2011, see informative Annex ZA, which is an integral part of this document.“ !When comparing EN 494:2004+A3:2007 and the previous edition EN 494:2012, the following paragraphs had been changed or
32、added: 3.10, 3.11, 5.1.1, Table 2, 5.3.3.1, 5.3.3.4, 5.6.3, Table 6, 6.3.2, 7.4.2.1 and Annex ZA.“ A distinction has been made between product appraisal (type tests) and routine quality control requirements (acceptance tests). The performance of a roof or another building part constructed with these
33、 products depends not only on the properties of the product as required by this document, but also on the design, construction and installation of the components as a whole in relation to the environment and conditions of use. According to the CEN-CENELEC Internal Regulations, the national standards
34、 organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxemb

DIN EN 494:2015-12 EN 494:2012+A1:2015 (E) 5 1 Scope This European Standard specifies the technical requirements and establishes methods of control and test as
36、well as acceptance conditions for fibre-cement profiled sheets and their fibre-cement fittings for one or more of the following uses: roofing; internal wall finishes; external wall and ceiling finishes. For the purpose of this European Standard, fibre-cement profiled sheets are classified according
37、to their height of corrugation and their mechanical characteristics. This European Standard covers fibre-cement profiled sheets reinforced with fibres of different type as specified in 5.1.1, with and without factory applied coating. This European Standard does not include calculations with regard t
38、o works, design requirements, installation techniques, wind uplift or rain proofing of the installed sheets. NOTE Some of these requirements can be applied, after agreement, to curved sheets for specific applications. 2 Normative references The following documents, in whole or in part, are normative

45、 The corrugations are defined by their pitch a and their height h. 3.2 acceptance test test to establish whether a batch of sheets, drawn either from continuous production or from a consignment, conforms to a specification Note 1 to entry: Test methods and specification limit values are specified in
46、 this document. Sampling levels and acceptance criteria are given in !6.2.2“. 3.3 type test test carried out to demonstrate conformity with the requirements of this document or for the approval of a new product and/or when a fundamental change is made in formulation and/or method of manufacture, the
47、 effects of which cannot be predicted on the basis of previous experience Note 1 to entry: The test is performed on the as delivered product, but is not required for each production batch. 3.4 acceptable quality level (AQL) quality level which in a sampling plan corresponds to a specified, relativel
48、y high probability of acceptance Note 1 to entry: It is the maximum percent defective (or maximum number of defects per 100 units) that for purposes of sampling inspection can be considered satisfactory as a process average. Note 2 to entry: A sampling scheme with an AQL of 4 % means that batches co
49、ntaining up to 4 % defective items have a high probability of acceptance. 3.5 as delivered same condition as the producer intends to supply the product after completing all aspects of the process including maturing and, when appropriate, painting 3.6 short sheet sheet having a length less than or equal to 0,9 m 3.7 long sheet sheet having a length greater than 0,9 m DIN EN 494:2015-12 EN 494:2012+A1:2015 (E) 7 3.8 upper face face normally exposed to the weather
