ASTM F1692-01(2011)
(Test Method)Standard Test Method for Life Evaluation of a Turbine-Powered Nozzle for Household Central Vacuum Cleaning Systems
Standard Test Method for Life Evaluation of a Turbine-Powered Nozzle for Household Central Vacuum Cleaning Systems
SIGNIFICANCE AND USE
The test results provide an indication of the turbine-powered nozzle life. The end of turbine life will be judged in accordance with 3.1.1.
SCOPE
1.1 This test method covers the turbine-powered nozzle used in household central vacuum cleaning systems.
1.2 This test method provides a test for determining the operating turbine life in hours by an accelerated laboratory procedure. The turbine is tested while mounted and operated in the power nozzle.
1.3 This test method covers only the turbine-powered nozzle. The system used to provide the airflow source is not under consideration.
1.4 This test method is limited to the determination of turbine life for a household turbine-powered 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.
