What is ISO 3303-2 about?
ISO 3303 discusses rubber or plastics-coated fabrics. ISO 3303-2 provides a test method to determine the strength of rubber or plastic-coated fabrics. ISO 3303-2 describes the hydraulic method to determine the bursting strength of rubber or plastic-coated fabrics.
The hydraulic method involves using one of two types of diaphragm bursting testers, designated type A and B, both operated by hydraulic pressure.
NOTE 1- The type A test machine applies to materials having bursting strengths ranging from 350 kPa to 5 500 kPa and the type B test machine applies to materials of bursting strengths ranging from 70 kPa to 1 400 kPa.
Who is ISO 3303-2 for?
ISO 3303-2 on on the bursting strength of coated fabrics is useful for:
- Manufacturers of products made from rubber and plastic-coated fabrics
- Research and testing facilities
Why should you use ISO 3303-2?
Bursting strength is the capacity of a material (such as a paper or textile) or object (such as a metal pipe) to maintain continuity when subjected to pressure. The bursting strength of coated fabrics is often used as a measure of the multidirectional modulus of the material, as opposed to tensile properties which only guide the coated-fabric strength in one plane.
ISO 3303-2 describes the hydraulic test that uses an elastic diaphragm. The hydraulic test is suitable for the testing of lighter and medium-weight coated fabrics. Two aperture sizes are specified to allow the use of commercially available instruments, although results from the different machines might not be comparable.
ISO 3303-2 guides you to use the hydraulic test to help you determine the bursting strength of rubber and plastic-coated fabrics so that you can decide if the fabric strength matches your product requirements.
What’s changed since the last update?
