Standard Test Method for Life Evaluation of a Turbine-Powered Nozzle for Household Central Vacuum Cleaning Systems

SIGNIFICANCE AND USE
4.1 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

1.2 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.

7. Procedure for Turbine Life Evaluation
7.1 Determine the initial performance. The suction of the cleaner or airflow source, with the turbine nozzle attached, is to be
determined and will be used to ensure that no leaks develop to reduce the load on the nozzle during the test. For this initial test,
the nozzle opening is to be sealed to the ASTM plenum chamber with the manometer (or equivalent) connected to the plenum
chamber. The turbine nozzle is to have the agitator drive connected and a new filter bag in the cleaner or airflow source. The
agitator shall be operating freely, with the handle in operating position, as shown in Fig. 1.
7.1.1 With the turbine nozzle opening sealed to the plenum chamber and without an orifice plate in the holder, energize the
cleaner or airflow source at its rated voltage 6 1 % 61 % and rated frequency 61 Hz for 5 min. For vacuum cleaners with dual
nameplate voltage ratings, conduct the testing at the highest voltage. See 5.13 if an optional airflow source is used.
7.1.2 With the airflow source operating at the regulated voltages stated in 7.1.1, insert the sharp-edge orifice plate in the holder
on the orifice box, in accordance with 5.5 and 5.6.
7.1.3 Record the manometer reading of the combined turbine nozzle and airflow source as soon as the reading is stabilized. This
manometer reading is to be used as the baseline to monitor the degradation in performance during the test.
7.1.4 Record the wattage of the airflow source while connected to the turbine nozzle and mounted on the plenum chamber. This
wattage reading is to be used as the baseline to monitor the nozzle load during the test.
7.1.5 Repeat the initial test sequence described in 7.1 – 7.1.4, recording the manometer and wattage readings of only the cleaner
or airflow source connected to the plenum chamber.
7.1.6 The airflow and wattage reading shall be measured every 168 h to determine whether some component has failed and
degraded the performance, reducing the load on the nozzle during the life test. See 7.10 if degradation exceeds 40 %.
7.1.7 Monitor the suction at the turbine nozzle daily during the test, in addition to the weekly measurement on the plenum
chamber, to maintain loading and to ensure that no mechanical problems exist.
7.2 Use a new section of carpet and padding, in accordance with 5.11 and 5.12, without holes, tears, or other signs of wear, when
the test is started. Secure the carpet tautly. The lay of the carpet pile shall be such that, during the forward stroke, the turbine nozzle
moves in the direction of the lay of the carpet pile (see Fig. 1). Measure the carpet pile height to determine the carpet wear in
accordance with 7.5.1.
7.3 Install the turbine nozzle on the test fixture, as shown in Fig. 1, with the nozzle connected to the airflow source using a hose
as provided with the unit. If more than one typ
