1 Scope
This International Standard specifies a rapid method for assessing solid samples in
an aerobic suspension, by determining the inhibition of dehydrogenase activity of Arthrobacter globiformis using the redox dye resazurin.
It is applicable for assessing the effect of water-soluble and solid matter bounded
non-volatile contaminants of natural samples, such as soils and waste materials. The
test yields a result within 6 h and can therefore be used for screening potentially
contaminated material.
