Any failure integral with the motor, such as armature assembly, field assembly, housing(s) bearings, motor cooling fan, carbon
brush assemblies, motor-mounted non-resettable thermal protective devices, or any other component judged to be integral with the
motor, shall be judged as motor stoppage.

cleaning system with which the motorized nozzle is to be used.
5.14 Text Fixture—A moving surface, covered by the test carpet supported on the test pad, which moves with a horizontal

6. Sampling
6.1 Test a minimum of three units (or a larger sample size, if desired) of similar models using the same motor style and
amperage. Select all samples at random in accordance with good statistical practice. The results shall provide an 80 % confidence
level within 610 % of the mean value. If not, test additional samples or reduce the results by the penalty factor as calculated in
7.12.
7. Procedure for Motor Life Evaluation
7.1 Determine the initial performance. The suction of the cleaner or airflow source, with the motorized nozzle attached, is to
be determined and will be used to ensure that no leaks develop to reduce load on the nozzle during the test. For this initial test,
the nozzle opening is to be sealed to the ASTM plenum chamber with a manometer (or equivalent) connected to the plenum
chamber. The motorized 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 the operating position, as shown in Fig. 1.
7.1.1 With the motorized nozzle opening sealed to the plenum chamber and without an orifice plate in the holder, energize both
the cleaner or airflow source and the motorized nozzle at its rated voltage 61 % and rated frequency 61 Hz for 5 min. to stabilize
motor temperatures. If either component has a dual nameplate voltage rating, conduct testing at the highest voltage.
7.1.2 With the motorized nozzle and airflow source operating at the regulated voltages of 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 power 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 motorized nozzle 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 of 7.1 – 7.4, recording 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 the degradation exceeds 40 %.
7.1.7 Monitor the suction at the motorized 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 the motorized nozzle moves in the direction
of the lay of the carpet pile during the forward stroke (see Fig. 1). Measure the carpet pile height to determine the carpet wear in
accordance with 7.5.1.
7.3 Install the motorized nozzle on the test fixture, as shown in Fig. 1, with the nozzle connected to the air
