ASTM E1428 Test Standard for Evaluating the Performance of Antimicrobials on or on Polymeric Solids Against Staining by Streptomyce species (Pink Spot Organism)

The ASTM E1428 standard is designed to evaluate the susceptibility of flat two-dimensional vinyl films and other solid polymer products, as well as products that can come into direct contact with vinyl, to pink staining by the actinomycete bacteria Streptomyces species.

This test method may not be suitable for highly textured or porous surfaces. This test method is not suitable for evaluating darkly pigmented test specimens. Knowledge of microbiological techniques is recommended for these procedures.

Manufacturers often request ASTM E1428 for various polymeric materials. Some bacteria and melanin are known to cause unwanted stains on the surface of polymers.

ASTM E1428 is administered with tests against Pink Stain Organism and standardized test runs for 14 days. The results obtained from the test are interpreted by evaluating the degree of stain on the test sample.

The ASTM E1428 antimicrobial test can evaluate a product's performance against staining when exposed to microorganisms such as Streptomyce species that may be present in the environment.

The ASTM E1428 test method is widely requested by customers as part of Quality Control testing for product distribution. A Quality Control program is most successful with cyclical product testing from batch to batch.

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
