ASTM F1038-02(2023)

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.
Designation: F1038 − 02 (Reapproved 2023)
Standard Test Method for
Motor Life Evaluation of a Canister, Hand-held, Stick, and
Utility Type Vacuum Cleaner Without a Driven Agitator
This standard is issued under the fixed designation F1038; 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.
