| Standard number: | ASTM D0876-21 |
| Released: | 01.01.2021 |
| Status: | Active |
| Pages: | 12 |
| Section: | 10.01 |

1.1 These test methods cover the testing of general-purpose (Grade A), low-temperature (Grade B), and high-temperature (Grade C)2 nonrigid vinyl chloride polymer tubing, or its copolymers with other materials, for use as electrical insulation. For the purpose of these test methods nonrigid tubing shall be tubing having an initial elongation in excess of 100 % at break.
Note 1: These test methods are similar but not identical to those in IEC 60684–2.
1.2 The values stated in inch-pound units are to be regarded as standard, except for temperature, which shall be expressed in degrees Celsius. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The procedures appear in the following sections:
