Garment category
Covers technical rescue, emergency medical, wildland/urban-interface and applicable multifunctional garments.
Thermal and barrier requirements depend on the garment category.
NFPA 1950
PPE for technical rescue, EMS and wildland firefighting
Requirements & test methods
NFPA 1950-2025 sets requirements for personal protective equipment used in technical rescue, emergency medical operations and wildland or urban-interface firefighting.
Total heat loss · THL
Measures garment-material or composite heat loss. The wildland requirement excludes cold-weather outerwear and winter liners.
Minimum THL by garment category:
| Garment category | Minimum THL |
|---|---|
| Wildland garment material/composite | 500 W/m² |
| Technical rescue garment with liquid barrier | 400 W/m² |
Wildland thermal performance
Measures radiant protection, vertical-flame response and thermal shrinkage.
Radiant protection: cal/cm²; char length: mm; afterflame: s; thermal shrinkage: %.
Optional particulate protection
Measures filtration of the specified challenge particles in wildland garment materials.
Minimum particulate filtration efficiency: 70%.
Durability and garment design
Measures material and seam strength and cleaning dimensional change; covers sizing, closures, interfaces and labels.
Strength: N. Dimensional change: %. Certification covers the declared garment category and optional protection claims.
