Scope: This International Standard is used to determine the degree of disintegration of plastic materials in aerobic composting tests under defined pilot plant conditions. The test methods specified in this standard can be used to determine the impact on the test material during the composting process and the quality of the compost obtained, but cannot be used to determine the aerobic biodegradability of the test material (other test methods such as GB/T 19276.1-2003, GB/T 19276.2-2003, GB/T 19277-2003 can be used to determine the aerobic biodegradability of test materials). This standard is part of an overall plan to evaluate the compostability of plastics.
