Standard Scope What It Tests Output/Result PPE Focus

ASTM F1506

Fabric & garment specification Defines minimum design, labeling, and performance requirements for arc-rated and flame-resistant clothing Certified arc-rated garments with permanent labeling and laundering durability FR/arc-rated shirts, pants, coveralls, outerwear

ASTM F1959

Fabric testing Exposes fabric swatches to electric arc to determine the arc thermal performance Arc Rating (ATPV) in cal/cm² Base fabrics for FR/arc-rated clothing

ASTM F2621

Finished garment evaluation Exposes complete garments (coveralls, jackets, hoods, accessories) to arc to assess integrity Observed performance (ignition, melting, breakopen, closures, seams) Finished clothing and accessories

ASTM F2676

Eye & face protection performance Exposes safety glasses, goggles, or face shields to arc energy Pass/fail on structural integrity, optical clarity, ignition/melting Eyewear and face shields

ASTM F3272

Arc rating for face protection Exposes face shields, arc flash hoods, helmet/visor systems to arc energy with sensors Arc Rating value (ATPV for face PPE, cal/cm²) Face shields & hoods (quantitative rating)

Progression Across Standards

ASTM F1506 – Garment Specification Level
Defines the minimum performance, labeling, and design requirements for arc-rated clothing.

ASTM F1959 – Fabric Level
Establishes the arc rating (ATPV) of raw fabric materials before garment construction.

ASTM F2621 – Garment Evaluation Level
Tests the full garment or product to confirm real-world performance, focusing on design integrity (seams, closures, trim).

ASTM F2676 – Face/Eye Performance Screening
Qualitative evaluation of face and eye PPE to ensure products don’t melt, ignite, or fail dangerously under arc exposure.

ASTM F3272 – Face PPE Arc Rating
Provides a quantitative arc rating for face protection, aligning face shields/hoods with the same cal/cm² framework used for fabrics and garments.

 

How the Standards Work Together

NFPA 70E – Electrical Safety in the Workplace
Requires employers to perform an arc flash hazard assessment and provide PPE with arc ratings appropriate for the hazard.
• Uses ASTM F1959 (fabric), ASTM F2621 (garments), ASTM F2676 (eye/face performance), and ASTM F3272 (face PPE rating) as the technical basis for compliance.
• Establishes PPE Categories (CAT 1–4) that align with arc ratings in cal/cm².

CSA Z462 – Workplace Electrical Safety 
The Canadian counterpart to NFPA 70E, with nearly harmonized requirements.
• Also requires hazard assessments, arc-rated PPE, and safe work practices.
• References the same ASTM test methods: ASTM F1959, ASTM F2621, ASTM F2676, and ASTM F3272.
• Provides equivalent guidance to NFPA 70E for Canadian workplaces, with some Canadian-specific references.
• Establishes PPE Categories (CAT 1–5) that align with arc ratings in cal/cm².

 

End User Protection Focus

Fabric level
ASTM F1959 provides the arc rating of fabrics; ASTM F1506 sets the specification for acceptable arc-rated fabrics → NFPA 70E, CSA Z462 require arc-rated fabric.

Garment level
ASTM F1506 defines minimum garment requirements; ASTM F2621 tests finished garments for design integrity → NFPA 70E, CSA Z462 require garments to meet these standards.

Eye/face level
ASTM F2676 screens performance; ASTM F3272 provides a quantitative arc rating → NFPA 70E, CSA Z462 require compliant face shields/hoods, now arc-rated quantitatively.
