This standard covers the requirements, methods  of sampling and tests for both polycarbonate homopolymer, co-polymers and high-heat polymers. It  applies to unmodified materials ready for normal use  and materials modified for example, by colourants,  additives, fillers, reinforcing materials and polymer  modifiers, suitably compounded to ensure desired  performance of the parts manufactured from it by  any of the usual processing techniques like injection  moulding, extrusion, blow moulding, compression  moulding etc.
