ASTM F1506 Standard Performance Specifications for Flame Resistant and Arc Rated Material for Wearing Apparel for Use by Electrical Workers Exposed to Momentary Electric Arc and Related Thermal Hazards

This performance specification covers the design characteristics and associated test methods that relate specifically to the flame resistance of textile materials used in the fabrication of basic protection level occupational apparel worn by electrical workers who are exposed to momentary electric arc and related thermal hazards, such as exposure to open flame and radiant heat. When evaluated in accordance with the test procedures enlisted within the standard, knit fabrics and woven fabrics of different fabric weights shall conform to individually specified values of the following properties: colourfastness, such as laundering shade change, dry-cleaning shade change and dimensional change; initial flammability characteristics and flammability characteristics after 25 washes/dry-cleaning, such as char length, afterglow and afterflame time; and arc test rating. Knit fabrics shall additionally be tested and adhere accordingly to bursting strength characteristics. Conversely, woven fabrics shall also be tested and adhere accordingly to breaking load, tear resistance and seam slippage.

Performance Requirements

This specification provides performance requirements for clothing worn by electric utility workers and other personnel working around energised parts. In addition to non-thermal requirements, the standard requires the fabric to be flame resistant. Flame resistance here is measured using ASTM D6413 Vertical Flame Test (maximum 2.0 seconds afterflame and 6.0 inch char length). The arc rating is either the Arc Thermal Performance Value (ATPV) or Energy Break-open Value (Ebt) as measured by the ASTM F1959-06ae1 Arc Thermal Performance Test. This test meets all requirements for flammability resistance as required by the NFPA and ASTM.

The standard has a general requirement that thread, findings and closures do not contribute to the wearer's injuries in an electric arc exposure. Knit or woven fabrics may not melt and drip or have more than 2.0 seconds afterflame or 6.0 inches char length. Arc ratings must appear on garment labels.

Arc Rating

All electric arc flash protection fabrics must be tested to determine the arc rating, as required by ASTM F1506, NFPA 70E, NEC and OSHA 1910.269. The test to determine a fabric's arc rating is ASTM F1959, where a piece of fabric is exposed to an arc flash while sensors determine how it performed. The tested fabric has either an Arc Thermal Performance Value (ATPV) or Energy Break-open Threshold (Ebt).

Flash Fire Resistance

NFPA 2112 Standard for Flame Resistant Garments for Protection of Industrial Personnel Against Flash Fire, and

NFPA 2113 Standard for Selection, Care, Use and Maintenance of Garments Used for Protection Against Flash Fire. This standard requires that garments be certified NFPA 2112.


Body area burn injury is a key predictor of victim survival from a flash fire incident and the protective performance of flame resistant clothing systems over a range of flash fire exposure levels can be used to match protective clothing systems to identified flash fire hazards. Body burn injury detailed in NFPA 2112 and determined by standard test method ASTM F1930, stipulates that for a garment to comply with NFPA 2112, it must exhibit 50% or less total predicted body burn injury for a 2.0 cal/cm2 heat flux at intervals of 3.0 seconds. These standards specify design, performance, certification requirements and applicable test methods for flame resistant garments for use in areas at risk from flash fires. Third party certification is required.

Key Definitions

Performance Requirements

The NFPA 2112 standard requires FR fabrics to pass a comprehensive number of thermal tests including the following:

ASTM F2700 Heat Transfer Performance (HTP) Test

This test exposes fabric to a combination of radiant and conductive heat to test how much heat transfers through the fabric over time. Understanding how long a garment can withstand high heat exposure is important to understanding what hazards it can protect against. 

Heat Resistance and Thermal Shrinkage Test

Some standards also require fabrics to be tested for heat and thermal shrinkage. This is often referred to as the oven test. The fabric sample is placed in an oven at 260° C (500° F) for typically 5.0 minutes and it must not ignite, melt and drip, separate and shrink more than 10%.
