(Test Method)Standard Test Methods for Polytetrafluoroethylene Tubing
Standard Test Methods for Polytetrafluoroethylene Tubing
SIGNIFICANCE AND USE
4.1 The test methods in this standard are considered important to characterize polytetrafluoroethylene tubing. They are intended primarily for, but not limited to polytetrafluoroethylene tubing.
4.2 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.
