Plastics — Polycarbonate sheets — Types, dimensions and characteristics
This document specifies the requirements for solid, flat extruded sheets of polycarbonate (PC) for general applications. It applies specifically to sheets made of poly(p,p′-isopropylidene-diphenyl carbonate). The sheets can be coloured or colourless, and they can be transparent, translucent or opaque. The sheets can also be those that have a special weather-protective layer on one or both surfaces.
This document applies only to thicknesses equal to or greater than 1,5 mm.
