ASTM F1038-02(2011)
(Test Method)Standard Test Method for Motor Life Evaluation of a Canister, Hand-held, Stick, and Utility Type Vacuum Cleaner Without a Driven Agitator
Standard Test Method for Motor Life Evaluation of a Canister, Hand-held, Stick, and Utility Type Vacuum Cleaner Without a Driven Agitator
SIGNIFICANCE AND USE
The test results provide an indication of the motor life of an electric vacuum cleaner in operating hours. The end of the motor life will be judged in accordance with Section 3.
SCOPE
1.1 This test method is limited to evaluation of canister, hand-held, stick, and utility type vacuum cleaners without a driven agitator.
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 a vacuum cleaner.
1.3 The values as stated in inch-pound units are to be regarded as the standard. The values in parentheses are given 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 and health practices and determine the applicability of regulatory limitations prior to use.
