ASTM F2105-18

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F2105 − 17 F2105 − 18 An American National Standard
Standard Test Method for
Measuring Air Performance Characteristics of Vacuum
1
Cleaner Motor/Fan Systems
This standard is issued under the fixed designation F2105; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers procedures for determining air performance characteristics of series universal motor/fan systems
used in commercial and household upright, canister, stick, hand-held utility, combination-type vacuum cleaners, and household
central vacuum cleaning systems.
1.2 These tests and calculations include determination of suction, airflow, air power, maximum air power, and input power under
specified operating conditions.

NOTE 1—For more information on air performance characteristics, see References (1) through (2).
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.
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, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
