36、stic product or material will disintegrate during composting such that anyremaining plastic residuals are not readily distinguishable from the other organic materials in the finished product. Additionally,the material or product must not be found in significant quantities during screening prior to f

Additionally, the polymericproducts or materials must not introduce unacceptable levels of heavyregulated metals or other toxichazardous substances into theenvironment, upon sample decomposition.NOTE 2For a better und

40、erstanding of why these criteria are important, consult Guide D6002 andthe Compost Facility Operating Guide,7and CEN/TC261/SC4N99.6. Detailed Requirements6.1In order to be identified as compostable, products must pass the requirements of6.1 In order to be identified as compostable in municipal or in

41、dustrial aerobic facilities, products must pass the requirementsof 6.2, 6.3, and 6.4 using the appropriate laboratory tests, representative of the conditions found in aerobic composting facilities.Test finished facilities, which reach thermophilic temperatures.

For products that are made in multiple thicknesses or densities, such as films, containers and foams,only the thickest or most dense products need to be tested as long as the chemical composition and structure remains otherwisethe same. It is

43、 assumed that thinner gages and lower densities will also compost satisfactorily. Similarly, if additives are presentin test samples that pass testing, lower levels of the same additives are similarly passed.6.2 Disintegration During Composting:A plastic product is considered to have demonstrated sa
