GB/T 15305.3-2009Coated abrasives -- Abrasive belts -- Selection of width/length combinations (English PDF)

Foreword

The partial modification of the use of ISO 2976:2005 "Coated Abrasives belt width and length combinations to select" (in English).

This section according to ISO 2976:2005 redrafted.

Because of the special needs and requirements of the development of industry, this section at the time of adoption of international standards has been modified. These technical differences with Vertical single-line identification in the space covered by the terms of their margins.

This portion of the ISO 2976:2005 The main differences are as follows.

--- Table 1 increased 1350mm × 2800mm The size and limit deviations;

--- Table 1 is deleted width of 13mm and 15mm T - Dimensions and limit deviations;

--- Table 1 increased the width of the T series and a size limit deviation of 14mm;

--- Table 2 adds the dimensions of 210mm × 230mm and limit deviations;

--- Table 1 Delete the width T > 1400mm size of the series and its limit deviation;

--- Appendix A, Table A. 1 and Table A. 2 with Table 1 and Table 2, made the corresponding changes.

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

--- Delete foreword international standards;

--- The "this International Standard" be replaced by "of this standard." this Part replaces GB/T 15305.3-1994 "coated abrasive belt dimensions and tolerances." Section compared with the GB/T 15305.3-1994 The main changes are as follows.

--- Deletion of the GB/T 15305.3-1994 Chapter 2 basic dimensions and limit deviations;

--- Size combinations in addition to using ISO 2976:2005, the appropriate increase in the domestic common belt sizes;
