ANSI B74.19 90th Edition, January 4, 1990
TEST FOR DETERMINING MAGNETIC CONTENT OF ABRASIVE GRAINS
Includes all amendments and changes through Reaffirmation Notice , 1995
Additional Comments: W/D S/S BY UAMA B74.19
Published By:American National Standards Institute (ANSI)
Scope and Purpose
The purpose of this standard is to establish a nationally recognized basis for determining the magnetic content of abrasive grain used in the manufacture of grinding wheels. coated abrasive products. general polishing. and other general industrial uses such as pressure blasting. wire sawing. lithoplate graining. etc.
It is intended to serve as a common basis of understanding for abrasive grain producers. and for manufacturers. distributors. and users of these abrasive products. Abrasive grain is a natural or manufactured substance that is reduced by crushing to specific grit sizes. and is then made into products which are used for removing extraneous material by grinding. polishing. lapping. etc. Examples of some of the natural materials are corundum. emery and garnet. The manufactured materials include fused aluminum oxide and silicon carbide.
