ASTM D922-11

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.
1.2 This standard and IEC-60684-3-100 to -105 address the same subject matter but differ in technical content.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
