C, 40 CFR 799.6784 (column elution) ; or Method D, 40 CFR 799.6786 (generator 

column). 

6 . Environmental fate and pathways - ready biodegradation : According to ISO 

10634:1995(E) guidance by one of the following: 1) ASTM E 1720-01 (reapproved 

2008) (sealed vessel C02 production test); 2) ISO 14593:1999(E) (COz headspace test) ; 

3) ISO 7827:1994(E) (analysis of DOC); 4) ISO 9408:1999(E) (determination of oxygen 

demand in a closed respirometer); 5) ISO 9439 :1999(E) (C02 evolution test); 6) ISO
