This part of prEN 1013 specifies requirements for materials and performance of light transmitting profiled sheets of polyvinyl chloride produced to the desired profile by extrusion and/or forming for single skin applications. It has to be read in conjunction with the general requirements contained in prEN 1013-1. Requirements specified are relative to: sheet thickness, visual characteristics, longitudinal reversion, retention of profile, tensile impact strength, thermal ageing. Test methods are indicated as appropriate.
