The standard DIN EN ISO 15015 has been prepared by Technical Committee ISO/TC 61 "Plastics", in collaboration with Technical Committee CEN/TC 249 "Plastics", the secretariat of which is held by NBN (Belgium). The responsible German standardization committee is Working Committee NA 054-04-02 AA "Halbzeuge aus Thermoplasten" ("Thermoplastic semi-finished products") of the Plastics Standards Committee (FNK). This International Standard specifies the requirements and test methods for solid flat extruded sheets of impact-modified acrylonitrile-styrene copolymer materials: acrylonitrile-butadiene-styrene (ABS), acrylonitrile-(ethylene-propylene-diene)-styrene (AEPDS) (commonly known as AES) and acrylonitrile-styrene-acrylate (ASA), without fillers or reinforcing materials. It also applies to ABS, AEPDS and ASA sheet in rolled form. This International Standard applies only to sheet thicknesses from 0,25 mm to 20,0 mm.
