Standard Test Method for Determining the Change in Room Air Particulate Counts as a Result of the Vacuum Cleaning Process
SIGNIFICANCE AND USE
4.1 In this test method, the amount of particulate generated into the air by operating a vacuum cleaner over a specific floor covering that is contaminated with dust will be determined. Particles from the motor, floor covering, and the test dust will all be measured. The amount of dust generated in the laboratory practice will differ from that in residential/commercial installations because of variations in floor coverings, soil and other solid particulate compositions, the vacuuming process used by individual operators, the air exchange rate of heating, ventilation, and air conditioning (HVAC) systems, and other factors.
4.2 To provide a uniform basis for measuring the performance in 4.1, a standardized test chamber, equipment, floor covering material, and dust particulate are used in this test method.
4.3 Due to the large range of generated particle counts observed among products in the vacuum cleaner industry at the present time, the test results of the maximum particle counts generated under this test method are expressed in Log10 equivalents for evaluation and comparison of product performance.
SCOPE
1.1 This test method provides a laboratory test for the measurement of particulate generated as a direct result of the vacuuming process.
1.2 This test method is applicable to all residential/commercial uprights, canisters, stickvacs, central vacuum systems, and combination cleaners.
1.3 This test method applies to test dust removal from floor coverings not the removal of surface litter and debris.
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.5 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.
1.6 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.
