scope:

This test method is intended to assess susceptibility of polymer materials, as well as products that may directly contact the treated polymer, to staining by the Actinomycete Streptomyces species.

This test method is also suitable for evaluating dark-pigmented test samples since the bacterial growth inhibition can be assessed.

Familiarity with microbiological techniques is required. This test method should not be used by persons without at least basic microbiological training.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
