1.1 This specification covers the in-service care, inspection, testing, and use voltage of insulating line hose and covers for protection of workers from accidental contact with energized electrical wires or equipment. 1.2 The following safety hazards caveat applies only to the test...

4.1 The thermal resistance of a ceiling system is used to characterize its steady-state thermal performance. 4.2 The thermal resistance of insulation is related to the density and thickness of the insulation. Test data on thermal resistance are obtained at a thickness and...

1.1 These test methods cover the testing of bonded mica splittings and bonded mica paper to be used for commutator insulation, hot molding, heater plates, and other similar insulating purposes. 1.2 These test methods appear in the following sections: Test Sections Compressive Creep 4 - 10...

6.1 Method-It is possible that electrical insulation in service will fail as a result of tracking, erosion, or a combination of both, if exposed to high relative humidity and contamination environments. This is particularly true of organic insulations in outdoor applications...

1.1 This specification covers a crosslinked polyethylene insulation for electrical wires and cables in conductor sizes 14 AWG [2.08 mm2] and larger. The base polymer of this insulation consists substantially of polyethylene or a polyethylene copolymer. 1.2 This type of...

4.1 The information contained in this guide is general in nature because of: the great number of commercially available firestop systems globally; the quantity and variety of internationally published firestop system's listings; worldwide variations in building and fire code...
