(Test Method)Standard Test Method for Access Depth Under Furniture of Vacuum Cleaners
Standard Test Method for Access Depth Under Furniture of Vacuum Cleaners
SIGNIFICANCE AND USE
This test method is intended to provide a means of evaluating the effective cleaning depth under furniture.
Results of testing by this test method can be used as a basis for specifications on cleaning under furniture.
SCOPE
1.1 This test method covers the measurement of the operational ability of the vacuum cleaner, expressed as the access depth for a given furniture clearance above the floor.
1.2 This test method can be used in testing household and commercial vacuum cleaners.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 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
7.1 Upright Vacuum Cleaners (Fig. 1):
7.1.1 Place the upright vacuum cleaner in its most advantageous position for cleaning under furniture. Operate the vacuum
cleaner at the vacuum cleaner’s nameplate rated voltage 61 % and rated frequency 61 Hz with the nozzle height in the lowest
cleaning position on a bare floor surface.
7.1.1.1 For vacuum cleaners with dual nameplate voltage ratings, conduct the test method at the highest voltage.
7.1.2 The access depth is the distance (in inches or millimetres) measured from the front of the 0.75-in. (19-mm) diameter rod
(when in contact with the highest component of the vacuum cleaner) to the most advanced point of the inlet of the nozzle.
