Start with the hazard
Describe spark and slag intensity, exposure duration, orientation, abrasion and mechanical loading. Compare candidate materials against the actual hazard and the required performance test.
Confirm the treated construction
Identify the underlying fiberglass cloth, treatment, finished weight, thickness, width and roll length. Check cut-edge behavior and flexibility if the material will be sewn or repeatedly handled.
Validate before production
Agree the test method, acceptance criteria, sample size and report scope before order. A material-family name alone does not substantiate a performance claim.
Frequently asked questions
Should I choose vermiculite treatment only because it is called high temperature?
No. Choose by exposure and test requirements. Compare actual sample, substrate, treatment and application conditions.
