ASTM F922-01

Standard Test Method for Motor Life Evaluation of an Electric Motorized Nozzle

SCOPE
1.1 This test method covers the motorized nozzle used with household or commercial vacuum cleaner systems, that is, combination cleaners.
1.2 This test method provides a test for determining operating motor life in hours by an accelerated laboratory procedure. The motors are tested while mounted and operated in the motorized nozzle.
1.3 This test method covers only the motorized nozzle. The system used to provide the airflow source is not under consideration.
1.4 This test method is limited to the determination of motor life for an electrically powered household or commercial motorized nozzle.
1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
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.
