Different testing methods are applicable for materials with different properties. Below is a summary of the applicability of ISO 9408. Please check our Method Selection Guide to select the most appropriate method for your materials. You can also find the applicability for many other methods on Aropha Resource Center
|Test||Analytical method||Sample info required *||Poorly soluble||Volatile||Adsorbing|
|ISO 9408 (Closed respirometer test)||Oxygen consumption||ThOD or COD *||+||+/-||+|
*"Sample info required" is the information needed to calculate the biodegradation percentages. This must be available for a selected method.
*"ThOD" can be easily calculated based on the formula of the sample. Try our Online ThOD Calculator.
*"COD" can be used as an alternative to ThOD if the formula of the material is unknown. We provide COD analysis at Aropha.
