1.1 This practice provides information on apparatus, safety, pre-test preparation, and procedures for conducting field tests of polyamide-12 (PA12) pressure piping systems after installation using gaseous testing media such as un-odorized inert non-toxic gas or air, and applying pressure to determine if leaks exist in the system (pneumatic leak testing). This practice applies only to testing to discover leakage. Testing for other purposes such as testing to establish operating pressure is beyond the scope of this practice. 1.2 Leak testing with pressurized gaseous testing media shall be used only if one or both of the following conditions exists: 1.2.1 The piping system is so designed that it cannot be filled with a liquid, or 1.2.2 The piping system service cannot tolerate traces of liquid testing media. 1.3 Where hydrostatic testing is specified in contract documents or by the authority having jurisdiction, testing using pressurized gaseous testing media (pneumatic) testing shall not be substituted without the express consent and authorization of the authority having jurisdiction. 1.4 Some manufacturers prohibit or restrict testing of their products with pressurized gaseous testing media. Contact component manufacturers for information. Where the manufacturer of a test section component prohibits or restricts testing with pressurized gaseous testing media testing in accordance with this practice shall not be used without the express consent and authorization of the authority having jurisdiction and the component manufacturer. NOTE 1—Components that are not suitable for testing with gaseous testing media may not be suitable for service with pressurized gas. 1.5 This practice does not address leak testing using pressurized liquids (hydrostatic testing). For field leak testing using pressurized liquids, consult the manufacturer for guidance. 1.6 This practice does not apply to leak testing of nonpressure, negative pressure (vacuum), or non-PA12 (polyamide-12) piping systems. 1.7 This practice does not apply to fuel gas piping systems that extend from the point of delivery to the appliance connections. For other than undiluted liquefied petroleum gas (LP-Gas) systems, the point of delivery shall be considered to be the outlet of the service meter assembly or the outlet of the service regulator or service shutoff valve where no meter is provided. For undiluted LP-Gas, the point of delivery shall be considered to be the outlet of the final pressure regulator, exclusive of line gas regulators, in the system. This practice does not apply to LP-Gas systems covered under NFPA 58. 1.8 This practice is intended for use with PA12 pressure piping that conveys gaseous media under pressure (compressed gas) if the owner or operator or installer of the line does not have an established leak testing procedure that is acceptable to the authority having jurisdiction. 1.9 Warning—Failure during a pressurized gaseous testing media leak test can be extremely violent and dangerous because energy that is applied to compress the gaseous testing media and to pressurize the system will both be suddenly released. NOTE 2—To illustrate the violent hazard of failure, assume a 5 HP compressor is used to raise the test section to test pressure and that it takes 1 h to achieve test pressure. If sudden rupture occurs, energy release may occur in 2 s. Therefore, the horsepower of the energy release would be 5 HP × 1 h × 3600 s/h / 2 s = 9000 HP. Further, if diameter is doubled, energy release is four times greater. For an example test section that is twice the diameter, energy release would be 36 000 HP. 1.10 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
