This specification establishes requirements and test methods for dimensions and tolerances of central-vacuum hose inlet valve sockets. The requirements pertain to the dimensions, tolerances, and socket dimensions. The test methods include sampling and conditioning.1.1 This specification establishes requirements and test methods for dimensions and tolerances of central-vacuum hose inlet valve sockets.1.2 All notes and footnotes shall be considered as non-mandatory requirements of the specification.1.3 This specification does not apply to inlet valve back-up (or mounting) plates.1.4 This standard is applicable to universal valves marked with ASTM F2863, and does not limit proprietary valve designs.1.5 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.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The test results enable the comparison of A-weighted sound emission from central vacuum power units when tested under the condition of this test method.1.1 This test method calculates the overall A-weighted sound power level emitted by central vacuum power units, intended for operation in domestic applications. This standard applies to the power unit only at the power unit location. To test the sound power level of a central vacuum at the user’s location, refer to Test Method F1334.1.2 A-weighted sound pressure measurements are performed on a mounted central vacuum power unit in a semi-reverberant room. This test method determines sound power by a comparison method for small noise sources, that is, comparison to a broad band reference sound source.1.3 This test method describes a procedure for determining the A-weighted sound power level of small noise sources. This test method uses a non-special semi-reverberant room.1.4 Results are expressed as A-weighted sound power level in decibels (referenced to 1 pW).1.5 The values stated in inch pound units are to be regarded as the standard. The values in parentheses are for information only.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The test results provide an indication of the turbine-powered nozzle life. The end of turbine life will be judged in accordance with 3.1.1.1.1 This test method covers the turbine-powered nozzle used in household central vacuum cleaning systems.1.2 This test method provides a test for determining the operating turbine life in hours by an accelerated laboratory procedure. The turbine is tested while mounted and operated in the power nozzle.1.3 This test method covers only the turbine-powered nozzle. The system used to provide the airflow source is not under consideration.1.4 This test method is limited to the determination of turbine life for a household turbine-powered nozzle.1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
