(Test Method)Standard Test Method for Determining Energy Consumption of Vacuum Cleaners
Standard Test Method for Determining Energy Consumption of Vacuum Cleaners
SIGNIFICANCE AND USE
This test method provides an indication of the amount of energy usage of the vacuum cleaner while operating over a specified cleaning area at a specified stroke speed and total number of cleaning strokes.
The test area is divided into a number of strips, the strip being defined as the width of the power head or nozzle. For the purpose of this procedure, the cleaning area is specified as 10 m2 (15 500 in.2), the stroke speed is defined as 0.5 ± 0.03 m/s (1.7 ± 0.1 ft/s), with a total of 10 strokes per strip.
In order to provide a uniform basis for measuring the performance described in 1.1, standardized test carpets are employed in this procedure.
SCOPE
1.1 This test method covers only a laboratory test for determining the energy usage-of household and commercial upright, canister, stick, and wet/dry vacuum cleaners operating on carpet when tested under specified conditions.
1.1.1 This procedure may be used in conjunction with other performance criteria, such as cleaning effectiveness.
1.1.2 Vacuum cleaners, other than upright vacuum cleaners, that provide a carpet-cleaning function are tested in accordance with the carpet-cleaning instructions provided in the manufacturer’s instruction manual. If the manufacturer’s instruction manual does not contain instructions for a carpet-cleaning function, the vacuum cleaner is not within the scope of this procedure.
1.2 This test method is applicable to household and commercial types of vacuum cleaners.
1.3 The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are mathematical conversions that are provided for information only and are not considered standard.
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 and health practices and determine the applicability of regulatory limitations prior to use.
