ASTM F1506-18 Published

ASTM F1506-18 Standard Performance Specification for Flame Resistant and Electric Arc Rated Protective Clothing Worn by Workers Exposed to Flames and Electric Arcs has been published with substantial changes to small-scale testing as summarized below:

  • Testing for dimensional change and colorfastness may be performed and documented per the garment manufacturer instructions. If testing at a third-party lab like ArcWear and no instructions are given, the default methods of AATCC 61 Method 2A for colorfastness and 5 wash cycles using AATCC 135 method 3, IV, Aiii for dimensional change will be used for evaluations.  Manufacturers may state the specified minimum colorfastness requirements and maximum dimensional change (or default to a +/-5% requirement).
  • NFPA 2112 wash cycles are now permitted to be used for vertical flame testing. Vertical flame testing to ASTM D6413 must be performed before and after a minimum of  25 wash cycles and both the AATCC 135, 3, IV, Aiii method and the NFPA 2112 wash cycle are accepted. This will be helpful for those with multi-hazard products
  • Section 7 has clarified that the test methods in ASTM F1506 are for fabrics
  • Optional Tear Testing to ASTM D2262 has been removed

A copy of the new edition of the standard can be purchased here. NFPA 70E, which cites ASTM F1506 as a method of compliance for arc flash clothing, has included conformity assessment requirements. Manufacturers may choose to self-declare (the historical requirement), use accredited test data and a registered quality management system, or opt for third-party certification.
