ASTM F820 - 11 standard test method for measuring air performance characteristics of central vacuum cleaning systems
The test results allow the comparison of the maximum air power available when no dirt has been introduced into the vacuum cleaning system, that is, a completely clean filter or an empty, clean dirt container.
1.1 This test method covers procedures for determining air performance characteristics of household central vacuum cleaning systems, which use a flexible cleaning hose assembly and incorporates a series universal motor(s). This test method does not apply to the carpet cleaning mode of operation where dirt or debris is involved.
1.2 These tests and calculations include determination of suction, airflow, air power, maximum air power, and input power under standard operating conditions (see Note 0).
For more information on air performance characteristics, see Refs ().
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
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 0.
