7. Procedure
7.1 Equip the vac with a new filter.
7.2 Weigh the empty vac including the power supply cord. (Do not include the hose or any accessories.)
7.3 Unit must be on a level surface and the shut-off device must be in place if the unit is designed to be used with one.
7.4 Level of the water to be picked up shall be lower than the floor level of vac such that no siphoning occurs.

7.5 Tests are to be conducted at the nameplate voltage (61 %) and frequency (61 Hz), when measured at the appliance plug.
For cleaners with dual nameplate voltage ratings, conduct tests at the highest voltage.
7.6 Using the largest hose supplied with the unit, vacuum water into the vac-tank. Maintain a water pick up rate of 2 gal/min
throughout the filling cycle.
7.7 Collect water with the vac until either one of the following occurs:
7.7.1 The unit stops collecting water, or
7.7.2 Water overflows from the vac.
7.8 Stop unit and disconnect hose from the vac. Any water remaining in the hose shall not be included in the maximum
functional volume.
7.9 Weigh the filled vac, including the power supply cord.

7.11 Record the maximum functional wet volume in gallons (litres) to the nearest tenth.
7.12 Repeat steps 7.1 through 7.12 two more times. The average of the three tests represents the maximum wet functional
volume that the utility vac is capable of collecting.
8. Precision and Bias
8.1 Precision—These statements are based on an interlaboratory test involving six laboratories and four units. The range of
maximum functional volume of the units was from 3.8 to 13.5 gal.
8.1.1 Repeatability (Single-Operator-Laboratory, Multiday):
8.1.1.1 Repeatability for wet volume values of 5 gal and under, within a laboratory divided by the average (coefficient of
variation) was found to be 4.5 % or less. Two values from a sample of three should be considered suspect (at the 95 % confidence
level) if they differ by more than 12.8 %.
NOTE 2—The percent difference = (larger − smaller) ⁄(larger) × 100.
8.1.1.2 Repeatability for wet volume values of over 5 gal, the standard deviation within a laboratory divided by the average
(coefficient of variation) was found to be 2.5 % or less. Two values from a sample of three should be considered suspect (at the
95 % confidence level) if they differ by more than 7.1 %.
NOTE 3—The percent difference = (larger − smaller) ⁄(larger) × 100.
8.1.2 Reproducibility (Multilaboratory, Multiday):
8.1.2.1 Reproducibility for wet volume values of 5 gal and under, the standard deviation divided by the average (coefficient of
variation) with a single unit tested in different laboratories was found to be 10.7 % or less. Two such values should be considered
suspect (at the 95 % confidence level) if they differ by more than 33 %.
8.1.2.2 Reproducibility for wet volume values over 5 gal, the standard deviation divided by the average (coefficient of variation)
with a single unit tested in different laboratories was found to be 3.2 % or less. Two such values should be considered suspect (at
the 95 % confidence level) if they differ by more than 11.5 %.
8.2 Bias—No justifiable statement can be made on the bias of this test method for the properties listed. The true values of the
properties cannot be established by acceptable referee methods.

X1. DETERMINATION OF 90 % CONFIDENCE INTERVAL
X1.1 The most common and ordinarily the best single estimate of the population mean μ is simply the arithmetic mean of the
measurements. When a sample is taken from a population, the sample average will seldom be exactly the same as the population
average; however, it is hoped to be fairly close so that the statement of confidence interval will bracket the true mean.
X1.2 The following procedure gives an interval which is expected to bracket μ, the true mean, 100(1 − α) % of the time. This
provides a 100(1 − α) % confidence level. α is the chance of being wrong, therefore, 1 − α is the probability of being correct.
