(Test Method)Standard Test Method for Motor Life Evaluation of a Built-In (Central Vacuum) Vacuum Cleaner
Standard Test Method for Motor Life Evaluation of a Built-In (Central Vacuum) Vacuum Cleaner
SIGNIFICANCE AND USE
4.1 The test results provide an indication of the motor life of an electric vacuum cleaner. The end of the motor life will be judged in accordance with Section 3.
SCOPE
1.1 This test method is limited to motor life evaluation of central vacuum cleaners.
1.2 This test method provides a test to determine operating life of the motor, before servicing is needed, by an accelerated laboratory procedure. The motor is tested while mounted and is operated in central vacuum cleaner.
1.3 The values as stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.
