Standard Test Method for Straight Line Movement of Vacuum Cleaners While Cleaning Carpets

SIGNIFICANCE AND USE
This test method measures the relative work required by the user during the cleaning operation for the movement of a vacuum cleaner in the home or other cleaning location. Relative work is defined as the work measured by the equipment described in this test method.
This measurement is relative to the work performed by the user of vacuum cleaners and may be used for comparison between vacuum cleaners.
The relation between actual vacuum cleaner usage and the method of operation is valid only if the vacuum cleaner user operates the vacuum cleaner properly and in accordance with the manufacturer's instructions.
SCOPE
1.1 This test method covers the measurement of the relative work required to move the carpet cleaning mechanism of an upright, canister, stick, or combination vacuum cleaner in a straight line with forward and backward stroking on a selection of typical carpeted surfaces.
1.2 This test method can be used in the testing of household and commercial vacuum cleaners.
1.3 This test method measures the relative work needed to move the vacuum cleaner with its motor or motors in operation.
1.4 This test method applies to the vacuum cleaning of carpets only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
