Besides the Sturm test another much used aquatic, aerobic biodegradation test is ISO 14851 - Determination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium - Method by measuring the oxygen demand in a closed respirometer. 

Some other norms for aquatic, aerobic biodegradation tests have also been published, but are not suitable for biodegradable polymers. They have been developed for pure chemical substances and monitor parameters such as dissolved organic carbon, which cannot be used for polymers. Examples are ISO 7827, ISO 10708, ISO 10707, ISO 9888 and ASTM D5864-00. 

Besides the Sturm test another frequently cited aquatic, aerobic biodegradation test is the ISO 14851 [14], in parallel developed by the same working group ISO TC 61/SC 5/WG 22 and also published in 1999. 

Several other norms for aquatic, aerobic biodegradation tests have been published as well but are not frequently used for biodegradable polymers. Mostly the conditions of incubation (mineral medium, inoculum, temperature, concentration, etc.), are identical or at least similar to the Sturm and MITI methods. The differences lie in the parameters that are being measured and the method for calculating the biodegradation. The following different tests can be used ...
