The COD of FAT - 92'358/A is 1123mg02/g

The inherent biodegradability of FAT - 92'358/A was determined in a 28 days Zahn-Wellens - Test according to the OECD Guideline for Testing of Chemicals, No. 302B, Paris 1981 and the EEC-Directive, L133 (pp. 99-105) Volume 31, May 88. The test was performed in compliance with the Good Laboratory Practice (GLP) Regulations of Switzerland. The test substance was tested in concentration of 150 mg/l DOC. The reference substance Diethylenglycol was also tested in a concentration of 150 mg/l DOC. Result: The bioelimination of the test substance FAT - 92'358/A after 28 days is : 2.4 % The bioelimination of the reference substance after 16 days is : 98.3 %

The biochemical oxygen demand of FAT - 92'358/A is determined by measuring the dissolved oxygen concentration before and after 5 days incubation at 20°C in different test concentrations diluted in water saturated with dissolved oxygen and containing a seed of microorganisms. The test was carried out according to ISO 5815 Second Edition 1989-08-01 (E) corresponding to 92/69/EEC C.5. The test was performed in compliance with the Good Laboratory Practice (GLP) Regulations of Switzerland. The BOD5 of FAT - 92'358/A : 0 mg 02/g
