Standard Test Method for Determining Energy Consumption of Vacuum Cleaners

SIGNIFICANCE AND USE
4.1 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.  
4.1.1 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 m/s ± 0.03 m/s (1.7 ft/s ± 0.1 ft/s), with a total of 10 strokes per strip.  
4.2 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.

ASTM F2607-08(2022)(Test Method)
Standard Test Method for Measuring the Hard Surface Floor-Cleaning Ability of Household/Commercial Vacuum Cleaners

SIGNIFICANCE AND USE
4.1 This test method will provide an indication of the ability of the vacuum cleaner in removing dry debris from hard surface floors. The cleaning ability in the laboratory test will not be the same as in home cleaning; however, in most cases, a vacuum cleaner that performs well in the laboratory will clean well in a home.  
4.2 To provide a uniform basis for measuring the performance described in 1.1, standardized test hard surface flooring and standardized test debris are used.
SCOPE
1.1 This test method provides only a laboratory test for determining the relative hard surface floor-cleaning ability of household/commercial vacuum cleaners when tested under specified test conditions.  
1.2 This test method is applicable to household/commercial types of upright, canister, combination, and stick vacuum cleaners that use a dry primary dirt receptacle and are intended for cleaning hard surface floors as a primary or secondary function.  
1.3 This test method applies only to the removal of dry debris from hard surface floors, not the removal of embedded dirt from carpet.  
1.4 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.  
1.5 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.

ASTM F608-22(Test Method)
Standard Test Method for Evaluation of Carpet Embedded Dirt Removal Effectiveness of Household/Commercial Vacuum Cleaners

SIGNIFICANCE AND USE
4.1 This test method provides an indication of the capability of the vacuum cleaner to remove embedded dirt from carpeting. This test method is based upon results of home cleaning tests so that, in most cases, a reasonable correlation exists between home and laboratory results. The amount of dirt picked up in the laboratory test may not be the same as in the home; however, it will show that, in most cases, a vacuum cleaner that performs well in the laboratory will perform well in a home. Laboratory results may differ due to variations in the homes, carpets, dirt, and other factors (see Section 6).  
4.2 In order to provide a uniform basis for measuring the performance described in 1.1, standardized test carpets and a standardized test dirt are employed in this procedure.
SCOPE
1.1 This test method covers only a laboratory test for determining the relative carpet dirt removal effectiveness of household/commercial vacuum cleaners when tested under specified conditions.  
1.2 This test method is applicable to household/commercial types of upright, canister, and combination cleaners.  
1.3 The test method applies to embedded dirt removal from carpets, not the removal of surface litter and debris.  
1.4 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.  
1.5 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.
