Biodegradation Plastic resolution rate% test Heavy Metal test Standard： Limit:
(ASTM 6400)
Method ISO 14855-1 (ASTM 6400)
Method Resolution test- ISO 14855-1 Standard： 1. Single polymer: more than 60% of the total organic carbon into CO2 2. Two or more kinds of the polymer: more than 90% of the total organic carbon is converted to CO2 Detection time shall not exceed 180 days
(ASTM 6400)
Notice: Compost the sample should be in the 58±2℃ last 45days to 90days, cannot be more then 4 months Validity: （1） Decrease in volatile solids content of R-value ≧ 30%
（2）Three disintegration test ‘s CV cannot over 10%
(ASTM 6400)
ASTM D6954 First Step: UV or Heating
ASTM D6954 Second : embrittlement endpoint, tensile test elongation less than 5%
The third step: According to ISO 14855-1 to test resolution rate
ASTM D6954
ASTM D6954 Finally: According to ASTMD6400-99 and test the seeds growth up
