Structural and proximity firefighting protective ensembles
NFPA 1970-2025 establishes requirements for structural and proximity firefighting ensembles, work apparel and related emergency-services protective equipment.
Tests the structural garment’s outer shell, moisture barrier and thermal barrier together.
Garment-composite requirements:
| Property | Requirement |
|---|---|
| Thermal protective performance · TPP | ≥ 35 cal/cm² |
| Total heat loss · THL | ≥ 205 W/m² |
| Evaporative resistance | ≤ 45 Pa·m²/W |
Tests garment materials for flame response and thermal shrinkage.
Average char length ≤ 100 mm; average afterflame ≤ 2 s; shrinkage ≤ 10% in either direction.
Measures strength of the outer shell, linings and barriers.
Tear strength: outer shell and collar lining ≥ 100 N; moisture and thermal barriers ≥ 22 N. Outer-shell and collar-lining breaking strength after washing ≥ 623 N.
Tests water and liquid penetration through barrier material and seams.
Water penetration resistance ≥ 172 kPa. No penetration by the specified test liquids for at least 1 h.
Covers finished-product construction, interfaces and labeling.
Certification identifies the NFPA 1970 product category and configuration.
