Fabric testing evaluates specific physical, chemical, or performance characteristics of a fabric.
For example, testing may examine:
- Colorfastness
- Shrinkage
- Tensile strength
- Fiber composition
- pH
- Restricted substances
Certification generally verifies that a company, material, product, or process meets the requirements of a defined standard or certification system.
For buyers, the two serve different purposes:
- A test report provides evidence about specific test results.
- A certification provides evidence of compliance with the requirements of a particular certification standard or system.
A fabric may therefore have both testing reports and certifications, depending on the buyer’s requirements.
