Classification4.1 The purpose of this specification is to establish requirements for identifying end items, where plastics or polymers are usedas a c

22、oating or incorporated into a substrate so that they do not interfere with their satisfactorily composting in commercial andmunicipal aerobic composting facilities. Products meeting the requirements outlined below should be labeled as “compostable inmunicipal or industrial aerobic composting facilit

Basic Requirements5.1 In order to compost satisfactorily, an end item must demonstrate each of the characteristics fo

24、und in 5.1.1 5.1.3, and whichare quantified in Section 6.5.1.1 Disintegration During CompostingAn end item will disintegrate during composting such that any remaining residuals(plastic, polymer, or substrate) are not readily distinguishable from the other organic materials in the finished product.Ad

25、ditionally,the material or product must not be found in significant quantities during screening prior to final distribution of the compost.5.1.2 BiodegradationA level of biodegradation for the plastic coatings and additives shall be established by tests undercontrolled conditions.5.1.3 No Adverse Im

26、pacts on Ability of Compost to Support Plant GrowthAfter incorporation with soils, the end items shallnot adversely impact on the ability of composts to support plant growth, when compared to composts derived from biowastewithout any addition of tested end items or reference materials. Additionally,

27、 the polymeric products or other materials must notintroduce unacceptable levels of heavy metals or other toxic substances into the environment, upon sample decomposition.NOTE 2For a better understanding of why these criteria are important, the reader should consult Guide D6002, Compost Facility Ope

28、rating Guide,8and EN 13432.6. Detailed Requirements6.1 In order to be identified as compostable in municipal or industrial aerobic facilities, end items must pass the requirementsof 6.2, 6.3, and 6.4 using the appropriate laboratory tests, representative of the conditions found in aerobic composting

29、 facilities,which reach thermophilic temperatures.

For end items that are made in multiple thicknesses or densities, such as films, co

31、ntainers and foams, onlythe thickest or most dense products need to be tested as long as the chemical composition and structure remains otherwise the same.It is assumed that thinner gauges and lower densities will also compost satisfactorily. Similarly, if additives are present in testsamples that p

32、ass testing, lower levels of the same additives are similarly passed.6.2 Disintegration During CompostingAn end item is considered to have demonstrated satisfactory disintegration if aftertwelve weeks in a controlled composting test, no more than 10 % of its original dry weight remains after sieving

33、 on a 2.0-mm sieve.The use of Test Method D5338, without the carbon dioxide-trapping component, or ISO 16929 are suitable methods of generatinglaboratory thermophilic composting conditions.6.3 BiodegradationAn end item, having a plastic coating(s) or additives are considered to have achieved a satis

34、factory levelof biodegradation if the criteria in 6.3.1 and 6.3.2 are met or exceeded.6.3.1 The plastic coating or polymeric additives must meet the requirements of subsection 6.3 of Specification D6400.6.3.2 Substrates used in the end item must individually satisfy the requirements of 6.3.2.1 or 6.

35、3.2.2, and 6.3.3.6.3.2.1 The substrates of the end item are to individually demonstrate that 90 % of the organic carbon is converted to carbondioxide using Test Method D5338 within a 180 days at 58C (62C), when compared to the positive control. The testing methodshall be Test Method D5338 unless it

36、is inappropriate for the type and properties of the material. As an alternative, onlyinternationally recognized standardized tests, which conclusively demonstrate biodegradability by means of microbial assimilationof the test materials shall be used, in particular ISO 14851:1999, ISO 14852:1999, and

37、 ISO 14855:1999.6.3.2.2 End items made of ligno-cellulosic substrates are permitted to fulfill the requirements of 6.3.2 by demonstrating that theyare “materials of natural origin” and therefore assumed to be biodegradable by showing that over 95 % of their carbon comes frombiobased resources, using

38、 D6866. Any polymers or additives derived from biobased sources that are blended with ligno-cellulosicsubstrates shall separately demonstrate that they meet the requirements of subsection 6.3 of Specification D6400, if they are morethan 1 % of the dry weight of the end item.6.3.3 Any organic constit

39、uent present in more than 1 % of the dry weight of the end item shall fulfill the biodegradationrequirements of subsection 6.3 of Specification D6400.6.3.3.1 The total portion of organic constitutents or additives that do not fulfill the requirements of 6.3.1 shall not exceed 5 %of the end item by w
