Significance and Use | |||||||||||||||||||||||||||||||||
4.1 These test methods include most of the test methods that are considered important to characterize nonrigid vinyl chloride polymer tubing. While they were developed initially for this type of extruded tubing, their use is not limited to this type of tubing. 4.2 Variations in these test methods or alternate contemporary methods are acceptable for use determine the values for the properties in this standard provided such methods ensure quality levels and measurement accuracy equal to or better than those prescribed herein. It is the responsibility of the organizations using alternate test methods to be able to demonstrate this condition. In cases of dispute, the test methods specified herein shall be used. 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.
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:
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. 1.5 For fire test caveats, see Section 15. |
