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. Link to Active This link will always route to the current Active version of the standard. Failure during a pressure leak test can be explosive, violent, and dangerous, especially if a compressed gas is used. Poisson-effect length reduction may affect or cause disjoining in other contiguous sections that have partially restrained or non-restrained joints, such as bell-and-spigot joints, when such joints are in-line with the test section.

To prevent Poisson-effect disjoining, take measures such as the installation of external joint restraints diametrical clamps and tie-rods on in-line non-restrained joints, installing in-line thrust anchors at the ends of the fully restrained section, or isolating the fully restrained test section from piping wstm non-restrained or partially restrained joints. For field leak testing using pressurized gas, see Practice F Work Item s – proposed revisions of this standard.

In a compressed gas test, both the pressure stress on the system and the energy used to compress the gas are released at a failure. When a tensile stress is applied to a material, it will elongate in the direction of the applied stress, and will decrease in dimension at right angles to the direction of the applied stress.

In the test phase, expansion is suspended by slightly reducing test pressure. Additional safety information is presented in Section 7 and throughout this standard.

Active view current version of standard. Contact the joint or connection manufacturer for information. Astj typically include visual examination of joint appearance, mechanical checks of bolt or joint tightness, and other relevant examinations.

Contact component manufacturers for information about testing with gas under pressure. Failure during a asmt leak test can be explosive, violent, and dangerous, especially if a compressed gas is used. Warning —Safety is of paramount importance when conducting hydrostatic pressure leak tests because testing under pressure may cause sudden violent rupture or failure.

In a compressed gas test, both the pressure stress on the system and the energy used to compress the gas are released at a failure. G2164 amount of make-up water expansion allowance will vary because expansion is not linear. Historical Version s – view previous versions of standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

This procedure compensates for expansion with an initial expansion phase, followed by a test phase. For safety reasons, some manufacturers prohibit or restrict pneumatic pressure testing of their products. Referenced Documents purchase separately The documents listed below are referenced within the subject ast, but are not provided as part of the standard.

To compensate for xstm, make-up water is added during the initial expansion phase. Work Item s – proposed revisions of this standard. For field-testing of plastic gravity flow sewer lines, see Test Method F See also Test Method F Under test pressure, piping materials will expand slightly in diameter and contract in length slightly according to the Poisson ratio of the material. For field-testing of plastic gravity flow sewer lines, see Test Method F For safety reasons, some manufacturers prohibit or restrict pneumatic pressure testing of their products.

Such systems may contain lower pressure rated or non-pressure rated components that cannot be isolated from test pressure, or temporary caps or closures may not be practical. Leakage or aztm usually occur at connections, joints, and mechanical seals where sealing under pressure is required.

The suitability of a piping system for pressure service and its pressure rating or operating pressure is determined solely by its design and its installed components.

It is the responsibility of the user of this astj to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

The ratio of decrease to elongation is the Poisson ratio. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

It does not verify if a piping material or a piping system design is suitable for pressure service. In these systems, leak inspections should be conducted during and after installation.
