This International Standard specifies test methods for measurement of the size and aspect ratio ofcrushed carbon-fibre-reinforced plastics (CFRP), especially for recycling purpose. In this InternationalStandard the shape of crushed CFRP, the fragment, is treated as a rectangular shape, and themeasurement of the long and short sides of the shape is described. It applies to fragments of thefollowing average dimensions:— length of the long side: 5 mm to 50 mm;— width of the short side: 1 mm to 10 mm.This International Standard provides three measuring methods, two methods are manual methodsusing microscope and scale and the third method is an automatic method using a measuring apparatus.Crushed CFRP obtained from thermosetting or thermoplastic resin matrices are covered by thisInternational Standard.NOTE If the crushed CFRP contain a lot of small fragments and fine particle, it is intended to screen out by asieve of 1 mm size before the measurement.
