See also Test Method F To compensate for expansion, make-up water is added during the initial expansion phase. 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. The amount of make-up water expansion allowance will vary because expansion is not linear.

In the test phase, expansion is suspended by slightly reducing test pressure. Link to F21644 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, asstm if a compressed gas is used. Additional safety information is presented in Section 7 and throughout this standard.

ASTM International – Standard References for ASTM F – 18

Contact component manufacturers for information about testing with gas under pressure. Leakage or faults usually occur at connections, joints, and mechanical seals where sealing under pressure is required.

For field leak testing using pressurized gas, see Practice F Historical Version s – view previous versions of standard. For safety reasons, some manufacturers prohibit f264 restrict pneumatic pressure testing of their products. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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. Warning —Safety is of paramount importance when conducting hydrostatic asgm leak tests because testing under pressure may cause sudden violent rupture or failure. Contact the joint or connection manufacturer for information.

Additional safety information is presented in Section 7 and throughout this standard.

The values given in parentheses are mathematical conversions to SI units that are provided for asttm only and astn not considered standard. 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. 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.

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.

Failure during a pressure leak test can be explosive, violent, and dangerous, especially if a compressed gas is used. Asstm Item s – proposed revisions of this standard.

Active view current version of standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and f21664 the applicability of regulatory limitations prior to use. This procedure compensates for expansion with an initial expansion phase, followed by a test phase. For field-testing of plastic ast flow sewer lines, see Test Method F 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.

In these systems, leak inspections should be conducted during and after installation. The ratio of decrease to elongation is the Poisson ratio.

Link to Active This link will aetm route to the current Active version of the standard. Under test pressure, piping materials will expand slightly in diameter and contract in length slightly according to the Poisson ratio of the material.

Work Item s – proposed revisions of this standard. Inspections typically include visual examination of joint appearance, mechanical checks of bolt or joint tightness, and other relevant examinations.

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 with non-restrained or partially restrained joints.

It does not verify if a piping material or a piping system design is suitable for asym service. 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.
