(Test Method)Standard Test Method for Measuring Maximum Functional Wet Volume of Utility Vacuum Cleaners
Standard Test Method for Measuring Maximum Functional Wet Volume of Utility Vacuum Cleaners
SIGNIFICANCE AND USE
This test method covers a procedure to determine the maximum functional wet volume that the utility vac is capable of collecting.
SCOPE
1.1 This test method is applicable to any vacuum cleaner that is classified as a utility vac.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only.
1.3 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.
