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. 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 7.8.1.
7. Procedures for Motor Life Evaluation
7.1 Determine initial performance as follows:
7.1.1 Connect the manometer (or equivalent) to the plenum chamber. Install a clean filter in the test vacuum cleaner before
conducting performance tests. (This is not required for units which do not use filters).
7.1.2 With the vacuum cleaner hose end (or nozzle) sealed to the plenum chamber and without an orifice plate in the holder,
energize the vacuum cleaner at its nameplate rated voltage 61 % and frequency 61 Hz until the vacuum cleaner reaches its normal
operating temperature. For vacuum cleaners with dual nameplate voltage ratings, conduct testing at the highest voltage.
7.1.3 With the vacuum cleaner operating at a constant rated voltage, insert the 0.75 in. (19.05 mm) diameter sharp-edge orifice
into the holder on the plenum chamber.
7.1.4 Record the manometer reading as soon as the reading stabilizes.
7.1.4.1 Take readings as soon as the manometer reaches a true peak. (On higher manometer readings, the liquid level may peak
droppeak, drop, and peak a second time. The second peak is the true peak reading. A person conducting the test for the first time
shall observe aat least one run before recording data). See Specification F431 for instructions on how to minimize the overshoot
(first peak) of the liquid level.
7.1.4.2 Take all readings within 10 s of the orifice plate insertion.
7.1.5 Record the wattage of the vacuum cleaner connected to the plenum chamber. The wattage reading is used to monitor the
vacuum cleaner load.
7.1.6 Monitor the wattage and the suction daily and measure on the plenum chamber every 168 h to ensure that a load is
maintained, that no mechanical problem has developed, and that performance has not degraded by more than 40 %. If degradation
exceeds 40 %, see 7.7.1 and 7.7.2
7.2 Install the vacuum cleaner on the test fixture with a 0.75 in. (19.05 mm) diameter sharp-edge orifice plate in the vacuum
cleaner hose (or nozzle)
