(Test Method)Standard Test Method for Evaluating the Sustained Air Performance and Exhaust Emission Efficiencies of Central Vacuum Cleaning Units
Standard Test Method for Evaluating the Sustained Air Performance and Exhaust Emission Efficiencies of Central Vacuum Cleaning Units
SIGNIFICANCE AND USE
4.1 The test results allow comparison of sustained air performance of central vacuum cleaners that employ various methods of separating the dirt from the air used to convey the dirt to the central power unit. The results will be expressed as a percentage of the original vacuum performance after loading a prescribed weight of media.
4.2 The test results will allow a comparison of emissions by measuring the media emitted during the test and expressing this as an Exhaust Emissions.
SCOPE
1.1 This test method is a laboratory test for determining the sustained air performance and Exhaust Emissions of a central vacuum cleaner when tested under laboratory conditions.
1.2 This test method is applicable to all central vacuum cleaners with or without any type of internal filter. This test method is intended to help indicate how performance may be affected after multiple times of vacuuming over an extended period of time.
1.3 The inch-pound system of units is used in this standard except for weight measurements, which are measured in grams. The values stated in parentheses are given for information only.
1.4 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.
1.5 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.
