Brief Summary of ASTM D 6400 & ASTM D 6868

Both ASTM D6400 and ASTM D6868 include the same three components of testing (the difference between the specification is that the criteria themselves are slightly different).

1.Disintegration During Composting (on final product)?? Measured the by physical breakdown of product to pass a 2mm sieve

2.Inherent Biodegradation(on individual constituents)

?              Measured by carbon dioxide (CO2)evolution as the product biodegrades

?              Or some materials can qualify for the “materials of natural original”exception in which?case biobased content must be measured by ASTM D6866

3.No Adverse Impacts on the Ability of Compost to Support Plant Growth (on final product)

?              Testing for heavy metals

?              Plant Growth Study

In addition, the material must be chemically characterized to defend product claims: 

FTIR & Ash Content (to help with fingerprinting the material) ?

Density (grammage) for bagasse and paper based products. ?

Which Standard Applies to Your Product? ?

ASTM D 6400 塑料is to be used for plastic products ?

ASTM D 6868 紙制品is used for products such as molded pulp products or coated paper, ?basically non-plastic items (may be an oversimplification, but expresses the general idea). ?

Sample size 送樣規格：5000g

Lead time 測試周期: 常規 Regular 5-8 months working days

FTIR, ash content, and regulated metals plus flourine – 3 weeks (can be done quicker if needed)
Biobased testing (ASTM D6866) – approximately 7 work days
Disintegration – about 18 weeks; includes 12 weeks of composting plus a bit of time to set up the test, then at the end of the test to make the final measurements and type the report
Ecotoxicity – about 3-4 weeks, this starts at the end of disintegration testing though
Biodegradation – up to 180 days (plus 2 weeks for setup & reporting) or as few as 45 days (plus 2 weeks); it is dependent on how fast the material biodegrades, not on how fast we work.

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。
