ASTM D1675-03
(Test Method)Standard Test Methods for Polytetrafluoroethylene Tubing
Standard Test Methods for Polytetrafluoroethylene Tubing
SIGNIFICANCE AND USE
The test methods in this standard are considered important to characterize polytetrafluoroethylene tubing. They are intended primarily for, but not limited to polytetrafluoroethylene tubing.
Variations in these methods or alternate contemporary methods of measurement may be used to 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 methods specified herein shall be used.
Note 2—Provision for alternate methods is necessary because of (1) the desire to simplify procedures for specific applications, and (2) the desire to eliminate redundant testing and use data generated during manufacturing process control, including that generated under Statistical Process Control (SPC) conditions, using equipment and methods other than those specified herein. An example would be the use of laser micrometers or optical comparators to measure dimensions.
SCOPE
1.1 These test methods cover procedures for testing polytetrafluoroethylene tubing for use as electrical insulation. The procedures appear in the following sections: Procedure SectionsASTMMethodsConditioning7 ...Dielectric Breakdown Voltage28-30 D 149, D 876 Inside Diameter8-13D 876 Mandrel Bend Test46-52 D 149, D 876 Melting Point41-45 D 3418, D 4895 Penetration Test26 and 27 D 876Specific Gravity36-40 D 792, D 1505 Strain Relief31-35 ...Volatile Loss20-25 ...Wall Thickness14-19...
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 the standard except for temperature, which is stated in degrees Celsius. Values in parentheses are for information only.
1.3 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. For specific warning statements, see Section 5.
