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 纸制品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). 


 

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。
