ANSI/UAMA B74.22-1991 (R2014) PDF

The scope of UAMA B74.22-1991 (R2014) is limited to 9" x 1/4" Type 27 portable grinding wheels that can be cracked in such a manner that the crack is not visible to the operator. If the 9" x 1/4" wheel passes the test then 7" x 1/4" wheels of the same design are also considered to have passed since the test conditions on a 9" x 1/4" wheel are much more severe than on a 7" x 1/4" wheel.
