Abstract

These test methods cover the equipment for, and the techniques of, testing vitrified clay pipe prior to installation. Tests using whole pipe determine the resistance to crushing and hydrostatic forces. Tests using pipe fragments measure the amount of water absorption of the pipe body and the quantity of acid-soluble material that may be extracted from it. <br>The values stated in SI units are to be regarded as the standard. <br><em>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.</em> <br><strong>Note 1</strong>&#8212;The following standards also apply to clay pipe and can be referenced for further information: ASTM C 12, C 425, C 700, and C 828.
