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 紙制品is used forproducts such as molded pp products or coated paper, ?basicallynon-plastic items (may be an oversimplification, but expresses thegeneral idea). ?

Leadtime 測試周期:常規(guī) Regar 5-8months working days
FTIR,ash content, and regated 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.

Others其他信息：

1、體外試驗是將樣品浸泡在溶液中，不同時間點，取出樣品稱重，根據(jù)重量變化看材料有無降解，

2、體內試驗是將樣品植入到動物皮下組織，不同時間點，處死動物，觀察樣品是否有降解，且進行局部的組織病理觀察。
