Management of houses. Gas supply system. Leak tightness test of the user’s liquefied petroleum gas (LPG) supply system

This technical specification establishes comprehensive procedures for conducting airtightness tests on liquefied petroleum gas supply systems serving individual residential premises. It outlines specific methodologies and criteria for assessing the integrity of gas piping networks, ensuring that installations meet strict safety requirements before being commissioned for use. The document details the necessary equipment, measurement techniques, and pressure testing protocols required to detect potential leaks within the distribution infrastructure. It applies to new installations as well as existing systems undergoing maintenance or modification. Guidelines are provided for interpreting test results and determining necessary corrective actions when deviations from acceptable leakage rates are identified. The scope includes verification of all joints, valves, and connection points within the user-side system. Adherence to these procedures helps maintain the safety of residents and prevents hazardous gas accumulation in enclosed spaces. The standard serves as a technical reference for engineers, inspectors, and service providers involved in gas system maintenance and safety audits.
