1、Designation:E100313Standard Practice forHydrostatic Leak Testing1This standard is issued under the fixed designation E1003;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates th
2、e year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the testing of components for leaksby pressurizing them inside with a liquid.1.2 This practice can be used on piping,valves,and con-tainers with welded
3、or fitted sections which can be sealed attheir ends and which are designed for internal pressure.1.3 Basic procedures are described based on the type ofinspection used.These procedures should be limited to findingleakage indications of 4.5 109mol/s(1 104Std cm3/s)2orlarger.1.4 UnitsThe values stated
4、 in SI units are to be regardedas standard.The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and are not considered standard.1.5 This standard does not purport to address the safetyconcerns,if any,associated with its use.It is the
5、 responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2.Referenced Documents2.1 ASTM Standards:3E543 Specification for Agencies Performing NondestructiveTestingE1316 Terminology for Nondes
