ASTM F1891 Standard Specification for Arc and Flame Resistant Rainwear 

Scope

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.

Key Definitions

Performance Requirements


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

Scope

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.

Performance Requirements 

Requirements must be met initially as manufactured as well as after five cleanings.

Tear Resistance

Material must have a trapezoidal tear 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 materials attached to the rainwear must be permanent and must not degrade the performance of the rainwear. 

Flame Resistance

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.

Thermal Protection

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:

Rainwear Construction

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.

ASTM E96/E96M Standard Test Methods for Water Vapour Transmission of Materials

Scope

These test methods cover the determination of water vapour transmission (WVT) of materials through which the passage of water vapour may be of importance, such as paper, plastic films, other sheet materials, fibreboards, gypsum and plaster products, wood products and plastics.

Significance and Use

The purpose of these tests is to obtain, by means of simple apparatus, reliable values of water vapour transfer through permeable and semi-permeable materials, expressed in suitable units. These values are for use in design, manufacture and marketing. A permeance value obtained under one set of test conditions may not indicate the value under a different set of conditions. For this reason, the test conditions should be selected that most closely approach the conditions of use.

Breathable Rainwear

Omega BreathabilityNon-breathable rainwear is designed to keep water out but also keep perspiration in. It creates an internal environment that stores heat which leads to workers becoming wet from perspiration even though no rain has passed through. Breathable rainwear is designed to collect and transmit perspiration out of the garment. This leaves the worker dry from both the transmitted perspiration and the rain.

Breathability is measured in two ways –

For a material to be considered breathable, it must have a:

About PTFE

PTFE membranes benefit from a number of features which enable them to be used in a variety of applications, including military, rail service, fire fighting and the electrical, oil and chemical industries. The membrane's high and low temperature resistance means the wearer is protected from extreme environmental conditions. PTFE membranes are designed for outside and extreme environments; wind, rain and severe temperature resistance are features needed for a variety of industrial applications. The lightweight, flexible and tactile design of PTFE allows for maximum comfort for the wearer over prolonged periods of time.

Features and benefits include:
