ASTM F1959/F1959M
Measures the arc rating of the fabric or material system as ATPV or EBT.
Arc rating in cal/cm², selected for the workplace exposure.
ASTM F1506
Flame-resistant and arc-rated protective clothing
Requirements & test methods
ASTM F1506-25 defines performance, construction and labeling requirements for flame-resistant and arc-rated clothing worn by workers exposed to electric arcs and related thermal hazards.
Flame resistance
Tests vertical-flame behavior before cleaning and after 25 cleaning cycles.
Char length (mm), afterflame (s), melting and dripping:
| Condition | Results to record |
|---|---|
| Before cleaning | Char length (mm), afterflame (s), material behavior |
| After 25 cleaning cycles | Char length (mm), afterflame (s), material behavior |
Strength and stability
Measures woven breaking and tear strength, knitted bursting pressure and dimensional change.
Breaking and tear force: N. Bursting pressure: kPa. Dimensional change: %.
Garment construction
Covers closures, seams, body coverage and product information.
Garment labeling includes the arc rating and traceable product identification.
Where the standard is used
Oil & Gas
Arc-rated clothing for electrical tasks at process facilities, selected against the task-specific electrical hazard assessment.
