NFPA 70E is the most widely adopted standard, which provides the guidelines on Hazard Category Ratings (HRC ratings) that protective clothing should meet. Protective clothing should then be independently tested to one of two standards:
Arc Flash Hoods and Faceshields
ASTM F2178-08 standard test method for determining the arc rating and standard specification for eye or face protective products.
Arc Flash Garments and Apparel
ASTM F2621-06 standard test method for determining response characteristics and design integrity of arc rated finished products in an electric arc exposure.
ENA NENS 09-2006 Guidelines
ENA NENS 09-2006 Guidelines: National Guidelines (Australia) for the selection, use and maintenance of personal protective equipment for electrical hazards) around Arc Flash protective clothing.
AS/NZS 4836:2011 Safe working on or near low-voltage electrical installations and equipment International Standards
AS/NZS 4836:2011 has specific requirements for PPE including Flame-Retardant clothing.
There are two key international standards (in USA - NFPA 70E: Standard for Electrical Safety in the Workplace and in Europe ENV 50354: Electrical Arc Protection).
Elliotts have selected NFPA 70E as the minimum performance standard for our range until a standard is formalised in Australia.
NFPA70E: The National Fire Protection Agency's (NFPA) 70E is the Standard for Electrical Safety Requirements for Employee Workplaces. NFPA70E requires employees to wear flame resistant protective clothing wherever there is a possible exposure to electric arc flash. NFPA70E is widely accepted throughout general manufacturing as well as the electrical industries.
NFPA 70E has a Two Category, FR Clothing Approach
The use of the following table is suggested as a simplified approach to assure adequate PPE for electrical workers within facilities with large and diverse electrical systems.
Clothing Applicable Tasks
Everyday Work Clothing ATPV > 8
Electrical Switching Clothing ATPV > 40
IMPORTANT: The information regarding NFPA 70E contained here is condensed for brevity. Users should consult NFPA 70E for complete information and conduct their own risk assessment. NFPA 70E is available from the National Fire Protection Association
ASTM F1506: Standard Performance Specification for Textile Materials for Wearing Apparel for Use by Electrical Workers Exposed to Momentary Arc and Related Thermal Hazards. The Standard was developed to give minimum performance specifications for Protective clothing. The major two requirement of this specification was that the fabric is flame resistant, determined by using the standard vertical flame test (ASTM D6413) and have received an Electric Arc Rating or ATPV.
ENV 50354: Electrical Arc Protection: This standard specifies Electrical arc test methods for material and garments, for use by workers at risk from exposure to an electrical arc.
NFPA 2112 is tyhe standard for Flame Resistant Garments for Protection of Industrial Personnel Against Flash Fire. The standard is targeted towards workers who are at risk of flash fires, primarily in the petrochemical industries. NFPA 212 is a voluntary consensus standard not a law. The standard is published by National Fire Protection Association (NFPA)
