This section GB/T 44127 Part of.

The partial modification of the use of ISO 603-4:1999 "abrasive products - Dimensions - Part 4. surface grinding/peripheral grinding wheel" (in English).

Taking into account China's national conditions, in the use of ISO 603-4:1999 when this part has made several modifications. About the technical differences have been incorporated into the text in which they are involved and the terms of the margin of a single vertical line identification. It gives a technical difference in Appendix A (Informative appendix) List of very different reasons for reference.

For ease of use, this section also made the following editorial changes.

--- The "this part of ISO 603" with the words "this section";

"." --- With a decimal point instead of a comma as the decimal point, "";

--- Delete international standards foreword.

This Part replaces GB/T 4127-1997 "bonded abrasive grinding wheel shape and size" section of content. The modifications are the following.

--- Such products is consistent with the name of the international standards in the name of "ordinary abrasive" to "abrasive."

--- Increasing the ISO 603-4:1999 type 1, type 5, type 7, type 20, type 21, type 22, Type 23, Type 24, Type 25, Type 26, 38 , 39 and the size of the wheel series.

--- Increased product marking, signage requirements and regulations.

This part is proposed by China Machinery Industry Federation.

This part of the National Standardization Technical Committee Abrasives (SAC/TC139) centralized.
