(Test Method)Standard Test Method for Motor Life Evaluation of an Upright Vacuum Cleaner
Standard Test Method for Motor Life Evaluation of an Upright Vacuum Cleaner
SIGNIFICANCE AND USE
4.1 The test results provide an indication of the motor life of an electric upright vacuum cleaner. End of motor life will be judged in accordance with Section 3.
SCOPE
1.1 This test method covers motor life evaluation of household or commercial single and dual motor upright vacuum cleaners (uprights with separate motors for creating the vacuum and driving the floor brush). Self-propelled or power-assist cleaners are not within the scope of this test method.
1.2 This test method is limited to evaluation of the upright vacuum cleaner electric motor(s).
1.3 This test method provides a test to determine operating life of the motor(s), before servicing is needed, by an accelerated laboratory procedure. Motor(s) are tested while mounted and operated in the upright vacuum cleaner.
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, which 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.
