(Test Method)Standard Test Method for Measuring Air Performance Characteristics of Central Vacuum Cleaning Systems
Standard Test Method for Measuring Air Performance Characteristics of Central Vacuum Cleaning Systems
SCOPE
1.1 This test method covers the procedures for determining air performance characteristics of household central vacuum cleaning systems which use a flexible cleaning hose assembly. This test method does not apply to the carpet cleaning mode of operation, nor does it apply to any operation where dirt or debris is involved.
1.2 This test method and calculations include determination of suction, air flow, air power, maximum air power, and input power under standard conditions.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. Note 1-For more information on air performance characteristics, see Ref (1) through (7).
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. A specific precautionary statement is given in Note 2.
