Electrical hazards are among the most serious risks in industrial workplaces. To protect workers, arc-rated clothing must be rigorously tested. One of the most critical tests is ASTM F1959, which determines the Arc Thermal Performance Value (ATPV) of garments. For companies sourcing FR and IFR garments, understanding this test ensures workers receive reliable protection.
ASTM F1959 is the Standard Test Method for Determining the Arc Rating of Materials for Clothing. It measures how well a fabric can withstand thermal energy from an electric arc.
Key points:
Tests arc exposure on a fabric sample using a controlled laboratory setup.
Determines the calories per square centimeter (cal/cm²) that the garment can safely withstand.
Produces the Arc Thermal Performance Value (ATPV), which helps assign NFPA 70E PPE Categories (CAT 1–4).
Arc flash incidents can cause severe burns, permanent injury, or even fatalities. ASTM F1959 ensures that:
FR and IFR garments provide real-world protection for electrical workers.
Employers can match PPE to workplace hazard levels.
Garments maintain integrity and arc resistance after repeated use.
Without proper arc flash testing, protective clothing may fail when it's needed most.
Both FR-treated fabrics and Inherently Flame-Resistant (IFR) fabrics are tested under ASTM F1959:
FR Garments: Fabrics treated with flame-retardant chemicals; effective but require careful maintenance.
IFR Garments: Fabrics with built-in flame resistance; protection is permanent and more durable over time.
Employers often choose IFR garments for high-risk electrical work due to long-term reliability.
At DOMEX SAFETY, we manufacture ASTM F1959-compliant FR and IFR garments that provide proven arc flash protection. Our range includes:
Arc-rated coveralls and jackets for electrical workers
Shirts and trousers designed for comfort and durability
Multi-standard garments compliant with ASTM F1959, NFPA 70E, ASTM F1506, and IEC 61482
Every garment is tested to ensure compliance, safety, and long-lasting performance.
ASTM F1959 arc flash testing is the backbone of electrical workwear safety. By choosing FR or IFR garments tested to this standard, employers protect workers from severe thermal hazards while ensuring compliance with international safety regulations.
