1.1 This specification covers nonrigid tubing of vinyl chloride polymer or its copolymers with other materials for use in electrical insulation in three grades, as follows:

1.1.1 Grade A--General-purpose.

1.1.2 Grade B--Low-temperature.

1.1.3 Grade C--High-t...

This specification establishes the requirements for two types of clear silicone varnished glass fabrics in the form of sheets, rolls, and tapes for use as electrical insulation. Type A fabrics are used where electrical properties are primarily required, while Type B fabrics are used where physica...

This specification applies to straight-cut (as opposed to bias-cut) plain weave greige (unfinished) glass fabric produced from continuous-filament yarns, suitable for use in the production of coated or treated fabric for electrical insulating purposes. This specification does not cover woven glas...

Method-Electrical insulation in service can 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 outdo...
