Electric Arc Resistance
ASTM F1891 Standard Specification for Arc and Flame Resistant Rainwear
This specification establishes applicable test methods, minimum physical and thermal performance requirements, suggested sizing and recommended purchasing information for rainwear for use by workers who may be exposed to the thermal hazards of momentary electric arcs and open flames. The objective of this specification is to prescribe fit, function and performance criteria for rainwear that meets a minimum level of thermal and physical performance when exposed to a laboratory-simulated electric arc or flame exposure.
Arc Rating: a term used to indicate the protection level of a garment. With rainwear, it is invariably equal to the ATPV.
Arc Thermal Performance Value (ATPV): the incident energy on a material that results in sufficient heat transfer through the material for a 50% probability of the onset of a second-degree burn injury.
Calorie: is the energy required to raise one gram of water one degree C.
Design Test: one made on a sample treated as representative of an individual product, which is not intended to be re-done unless components of the material change.
Energy Break-open Threshold (Ebt): the amount of energy needed to cause the material to break-open.
Heat Attenuation Factor (HAF): the percent of arc flash heat energy blocked by the material.
Material must be flame retardant (ASTM D6413), self-extinguish < 2 seconds, < 6” char length.
Must determine Arc Rating (ASTM F1959) – report results, no minimum required.
Must determine Heat Attenuation Factor (ASTM F1959) – report results, no minimum required.
Must determine Energy Break-open Threshold (ASTM F1959) – report results, minimum of 5 cal/cm2.
- Must not melt, drip or ignite at twice arc rating.
Flash Fire Resistance
NFPA 2112 Standard on Flame Resistant Garments for Protection of Industrial Personnel Against Flash Fire, and
ASTM F2733 Standard Specification for Flame Resistant Rainwear for Protection Against Flame Hazards
This specification establishes test methods, minimum physical and thermal performance criteria, a suggested sizing guide and suggested purchasing information for rainwear for use by workers who are potentially exposed to industrial hydrocarbon fires or other petrochemical fire hazards.
Requirements must be met initially as manufactured as well as after five cleanings.
Material must have a trapezoidal resistance of 6 lbs (2.72 kg) in the warp direction and 6 lbs (2.72 kg) in the fill direction.
Markings and Reflective Materials
These material attached to the rainwear must be permanent and must not degrade the performance of the rainwear.
Rainwear material must be flame resistant and must not melt and drip when tested in accordance with ASTM D6413 and must exhibit no more than a 2 second afterflame time and less than 6 inch char length.
Rainwear must be tested in accordance with ASTM F1930, a design test, after 1 washing and 1 drying. Testing parameters are set at a heat flux of 84 ± 2kW/m2 (2.0 ± 0.05 cal/cm2) and an exposure time of 3 ± 0.1 seconds. The following information is determined:
The average predicted total area body burn injury for the three specimens tested must be equal to or less than 40%.
Material response characteristics must be reported for all exposures. Characteristics are: afterflame time, energy break-open, charring, melting, dripping, garment ignition, embrittlement and shrinkage.
Must utilise materials, stitching, tapes, coatings, fasteners and closure materials that minimise heat conduction for the construction of compliant FR rainwear. Fasteners and closures used, for example, zippers, snaps, buttons etc. that are made from metal, must be covered with a layer of rainwear material on the inside of the garment such that these items of construction will not contact undergarments or the skin.
Structural seam integrity: seams must not exhibit a seam failure that creates a seam opening of greater than 51mm (2 inches).
Closure Function: closures must function (fully open) after the simulated fire exposure. Closures that do not fully open do not meet the performance requirements of this specification. All closures that do not fully open must be reported.
Manufacturer Label: states size, catalogue number, manufacturer's name and notation of conformance to ASTM F2733 and the label is permanently affixed in each rainwear item.
Statement of Conformance: the statement of conformance to this specification must be, "This rainwear meets or exceeds requirements for ASTM F2733 Standard Specification for Flame Resistant Rainwear for Fire Hazards."
Care Label: states instructions for cleaning and care and must be readable throughout the life of the garment.
Packaging Label: states name of manufacturer, size, material, catalogue number, date code and ASTM designation.
Material must withstand water pressure of 30 psig without leaking. The seams of the rainwear must not exhibit any evidence of leakage when exposed to water at 3 psig for two (2) minutes.
