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.

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 test method may involve hazardous materials, operations, and equipment. 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 and health practices and determine the applicability of regulatory limitations prior to use.
