This International Standard specifies a method for determining the bulk density of dry, uncompacted chopped strands of glass fibre which are commonly used for the reinforcement of thermoplastic resins. This test may be used for product control or for quality control.
This test method is not recommended for use when the chopped glass-fibre strands are wet, exceed a length of 8 mm or do not exhibit a reasonable ease of flow when transferred from one container to another.
NOTE This test measures the free-flowing bulk density. The bulk density of compacted material will be different than that measured by this test.
