The conditions described do not always correspond to the optimal conditions allowing the occurance of the maximum value of biodegradation. The procedure applies to substances which are soluble at the concentration used under the test conditions, non-volatile ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
