GENERAL REQUIREMENTS FOR GRINDING WHEELS
|Publication Date:||1 May 1992|
1. PURPOSE AND SCOPE. This standard applies to grinding wheels and other bonded abrasives. This standard does not apply to diamond tools I.e. wheels or honing stones or to specialities such as sharpening stones where radically different symbols are commonly used. This standard establishes a symbol for each of the most essential characteristics of a grinding wheel, and arranges these symbols in uniform sequence. This is an International Standard System of Markings* in accordance with ISO R525. Wheels bearing the same standard markings if made by different wheel manufacturers may not and probably will not produce the same grinding action. This desirable result cannot be accomplished because of the impossibility of correlating any measureable physical properties of bonded abrasive products in terms of their grinding action. * Refer to page 2 point 2.7.2 for an explanation of the Ford adaptation to the Standard Marking System.
