ASTM E2109-01 is a standard test method titled: "Standard Test Method for Determining the Relative Stain Resistance of Floor Coatings and Floor Coverings."
Developed by ASTM International (formerly known as the American Society for Testing and Materials), this specific version (the 2001 edition) outlines a procedure for evaluating how well a flooring material resists staining from common household and industrial agents.
| Feature | ASTM E2109-01 | ASTM D3654 (common for tapes) | |--------|----------------|-------------------------------| | Load application | Static shear (constant load) | Static shear (constant load) | | Substrate | Specified stainless steel or customer-defined surface | Stainless steel or specified panel | | Temperature control | Required (often 23°C, 40°C, 70°C) | Optional – ambient unless specified | | Failure criteria | Complete separation of adhesive from substrate or cohesive split | Similar, but E2109 includes more precise measurement of displacement | | Data analysis | Time-to-failure with Weibull or log-normal statistics recommended | Simple average and range | astm e2109-01 pdf
E2109 is more rigorous for engineering plastics and non-foam PSAs where creep behavior is critical.
To perform tests according to the 2001 standard, a laboratory must have: Apparatus:
| Equipment | Specification | |-----------|---------------| | Orbital shaker | 100–150 rpm, 35±1°C temperature control | | pH meter | ±0.1 unit accuracy | | Sterile pipettes | 1 mL, 5 mL, 10 mL | | Neutralizer | e.g., lecithin/polysorbate 80 broth | | Agar plates | Tryptic Soy Agar (TSA), Sabouraud Dextrose Agar (SDA) | | Incubator | 35±1°C for bacteria, 25±1°C for fungi | | Colony counter | Manual or automated |
The standard also specifies precise neutralizer validation steps to ensure that residual antimicrobial activity does not falsely reduce colony counts. ASTM E2109-01 is a standard test method titled:
A detailed description of the metallographic preparation is required to ensure valid porosity measurements.
