(Test Method)Standard Test Method for Access Depth Under Furniture of Vacuum Cleaners
Standard Test Method for Access Depth Under Furniture of Vacuum Cleaners
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 Inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
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.
