Brief Summary ofASTM D 6400 & ASTM D 6868
BothASTM D6400 and ASTM D6868 include the same three components oftesting (thedifference between the specification is that the criteriathemselves are slightly different).
1.DisintegrationDuring Composting (onfinal product) • Measuredthe by physical breakdown of product to pass a 2mm sieve
2.InherentBiodegradation(onindividual constituents)
• Measuredby carbon dioxide (CO2)evolution as the productbiodegrades
• Orsome materials can for the “materials of naturaloriginal”exception in which case biobased content must be measuredby ASTM D6866
3.NoAdverse Impacts on the Ability of Compost to Support PlantGrowth (onfinal product)
• Testingfor heavy metals
• PlantGrowth Study
Inaddition, the material must be chemically characterized to defendproduct claims:
FTIR& Ash Content (to help with fingerprinting the material)
Density(grammage) for bagasse and paper based products.
WhichStandard Applies to Your Product?
ASTMD 6400 塑料is to be used forplastic products
ASTMD 6868 纸制品is used forproducts such as molded pulp products or coated paper, basicallynon-plastic items (may be an oversimplification, but expresses thegeneral idea).
Samplesize 送样规格：5000g
Leadtime 测试周期:常规 Regular 5-8months working days
FTIR,ash content, and regulated metals plus flourine – 3 weeks (can bedone if needed)
Biobased testing (ASTM D6866)– approximately 7 work days
Disintegration – about 18weeks; includes 12 weeks of composting plus a bit of time to set upthe test, then at the end of thetest to make the final measurements and type thereport
Ecotoxicity – about 3-4 weeks,this starts at the end of disintegration testingthough
Biodegradation – up to 180days (plus 2 weeks for setup & reporting) or as few as 45 days(plus 2 weeks); it is dependent onhow fast the material biodegrades, not on how fast wework.

1、体外试验是将样品浸泡在溶液中，不同时间点，取出样品称重，根据重量变化看材料有无降解，
2、体内试验是将样品植入到动物皮下组织，不同时间点，处死动物，观察样品是否有降解，且进行局部的组织病理观察。
