Comparison: WA-101 vs. WA-102 Standards for Wallcoverings
WA-101 Standard:
- Focus: Polymer-coated fabric wallcoverings.
- Durability and Performance: Ensures high durability, scrubability, and washability, making it suitable for high-traffic institutional and commercial settings like hospitals and schools.
- Testing Methods:
- Dimensions and Mass: Measurement of length, width, thickness, and weight.
- Breaking Strength: Tested using both Grab Test and Cut Strip Test methods.
- Elongation: Measured during the breaking strength test.
- Bursting Strength: Tested with a bursting fixture.
- Puncture Resistance: Similar to the bursting test but uses a pointed instrument.
- Tearing Strength: Tested using Pendulum and Tongue Tear methods.
- Trapezoidal Tear: Uses a tensile tester and specific grip inserts.
- Adhesion Coating to Fabrics: Tested for the strength of the adhesive bond.
- Tack-Tear Resistance: Uses a specialized fixture for testing.
- Seam Strength and Dead Load Seam Strength: Measures the strength of seams.
- Crush Resistance: Tests material's resistance to crushing or cutting.
- Sustainability: Aligns with environmental standards like NSF-342, ensuring products are environmentally friendly and safe.
- Product Weight: Defines Type II wallcoverings as having a weight requirement of 20 ounces per 54" linear yard (DreamScape Walls) (Dreamscape Support).
- Types Covered: Categorizes wallcoverings into Type I and Type II based on their weight and durability.
WA-102 Standard:
- Focus: Textile wallcoverings.
- Durability and Performance: Ensures textile wallcoverings meet high standards of quality, including factors like colorfastness, tensile strength, and dimensional stability.
- Testing Methods: Similar to WA-101, includes tests for abrasion resistance, fading, and other physical stresses.
- Sustainability: Promotes environmentally friendly products in line with standards like NSF-342.
- Product Weight: Unlike WA-101, WA-102 does not define a weight requirement, allowing for lighter materials as long as they pass durability and safety tests (Dreamscape Support).
- Application Scope: Covers a range of textile wallcoverings suitable for various commercial applications where both aesthetics and durability are essential.
Summary Comparison:
| Feature | WA-101 | WA-102 |
