1.1 This test method is intended to qualitatively assess susceptibility of flat two dimensional vinyl films and other solid polymer products as well as products that may directly contact vinyl to pink-staining by the actinomycete bacteria Streptomyces species. This test method may not be suitable for highly textured or porous substrates.
1.2 This test method is not suitable for evaluating dark-pigmented test samples.
1.3 A knowledge of microbiological techniques is recommended for these procedures.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
