This standard contains Amendment 1 of 2014 which has been prepared in addition to the standard DIN EN 1013:2013-03. This European Standard specifies the requirements for light transmitting single skin profiled plastics sheets for internal and external walls, roofs and ceilings. It is applicable to single skin sheets which are used as a single layer or when assembled to form a multiple layer construction. The standard also specifies the test methods and provides for the evaluation of conformity and marking of the sheets. This standard differs from DIN EN 1013:2013-03 as follows: a) Clause 2 has been modified; b) the text of 5.20 "Dangerous substances" has been replaced; c) the standard has been brought in line with the EU Construction Products Regulation (CPR); the former Clause 7 "Evaluation of conformity" has been replaced by a new Clause 7 "Assessment and verification of constancy of performance - AVCP". And Annex ZA has been brought in line with the EU Construction Products Regulation (CPR); d) in the German version, the concepts "Brandverhalten von außen" and "Brandverhalten bei Beanspruchung von außen" have been replaced throughout the document by "Verhalten bei Beanspruchung durch Feuer von außen" (External fire performance).
