ASTM F479 Standard Specification for In-Service Care of Insulating Blankets
ASTM F479绝缘涂层在使用中维护的标准使用规范
This specification covers elastomeric seals (gaskets) used to seal the joints of plastic pipe used for gravity, low-pressure, and high-pressure applications. This refers to push-on joints which require no internal or external pressure to effect the initial seal. Tensile strength, elongation, hardness, compression set, accelerated aging, water immersion, ozone resistance, and force decay shall be tested to meet the requirements prescribed.This specification covers the in-service care, inspection, testing, and use voltage of insulating blankets for protection of workers from accidental contact with live electrical conductors, apparatus, or circuits. Blankets covered shall be designated as type I or type II; class 0, class 1, class 2, class 3, or class 4; style A or style B: type I - not resistant to ozone, made from a high-grade cis-1,4-polyisoprene rubber compound of natural or synthetic origin, properly vulcanized; and type II - ozone-resistant, made of any elastomer or combination of elastomeric compounds. Style A - constructed of the elastomers indicated under type I or type II, shall be free of any reinforcement; and style B - constructed of the elastomers indicated under type I or type II, shall incorporate a reinforcement. Electrical testing shall be performed to meet the requirements prescribed.
