Standard Specification for Nonrigid Vinyl Chloride Polymer Tubing

ABSTRACT
This specification covers three grades of nonrigid tubing of vinyl chloride polymer or its copolymers with other materials for use in electrical insulation. Clear transparent, black, white, yellow, green, blue, and red shall be considered standard colors. Colors other than these shall be considered special. Dimensional requirements to which tubing shall adhere are inside diameter, wall thickness, and commercial lengths. The tubing shall also conform to physical and electrical requirements, as follows: flammability; tensile strength; effect of elevated temperatures; ultimate elongation after immersion in oil; brittleness temperature; penetration resistance; volume resistivity; dielectric breakdown at high humidity; strain relief; and corrosive effect.
SCOPE
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-temperature.Note 1
This standard is similar but not identical to IEC-60684-3-100 to -105.
