ASTM E1428
ASTM E1428: Standard Test Method for Evaluating the Performance of Antimicrobials in or on Polymeric Solids Against Staining by Streptomyces species (A Pink Stain Organism).
What is ASTM E1428?
ASTM E1428 is a standardized laboratory method used to determine how effectively antimicrobial agents incorporated in or applied to polymeric solids prevent staining by Streptomyces species—commonly known as pink stain organisms. This test is essential for manufacturers of plastics, coatings, sealants, and other polymer-based products that require resistance to microbial staining in moist or humid environments.
Our ASTM E1428 Testing Process
- Inoculation: Samples are exposed to Streptomyces species under controlled laboratory conditions.
- Incubation: The inoculated samples are incubated for a specified period to promote possible staining.
- Evaluation: After a 14 day incubation period, each sample is evaluated for the degree of pink staining, and antimicrobial effectiveness is assessed.
- Comprehensive Reporting: You receive a detailed report including methods and results.
Industries that use ASTM E1428
- Marine: Vinyl and fabric products used on boats and in marine environments are particularly susceptible to pink stain and require antimicrobial treatments for durability. Examples include boat covers, sails, and upholstery.
- Construction: The test is used for polymeric building materials, including vinyl siding, roofing membranes, and flooring, where microbial growth can affect appearance and structural integrity over time.
- Consumer Goods: This includes a wide range of products made from polymers, such as:
- Household goods: Shower curtains, mattresses, and flooring.
- Footwear and sports equipment: Items that are frequently exposed to moisture and dirt.
- Outdoor furniture and equipment
