Arc- and flame-resistant rainwear
ASTM F1891-25 establishes thermal, physical and waterproof performance requirements for rainwear used by workers exposed to momentary electric arcs and open flames.
Determines the rainwear assembly’s arc rating and records ignition, afterflame, breakopen, melting, dripping and shrinkage.
Arc rating in cal/cm²; response observations at these exposure levels:
| Exposure level | Required observations |
|---|---|
| At least 1 × the arc rating | 2 typical exposures |
| At least 2 × the arc rating | 2 typical exposures |
Measures vertical-flame behavior of the specified rainwear layers and cleaning condition.
Char length (mm or in.), afterflame (s), melting and dripping.
Assesses physical performance before and after 5 cleanings using the specified care procedure.
Initial and post-cleaning results for the rainwear material.
Measures leakage through material and seams, tear strength and material mass.
Water pressure: kPa or psi; hold time: s or min; tear force: N or lbf; mass: g/m² or oz/yd².
