ISO 13942:2019 接着研磨製品—偏差と振れ公差を制限します | ページ 2

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISO's adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www.iso.org/iso/foreword.html .

This document was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 5, Grinding wheels and abrasives.

This second edition cancels and replaces the first edition (ISO 13942:2000), which has been technically revised. The main changes compared to the previous edition are as follows:

• Figures added for the following shape types: 2, 3, 4, 13, 16, 17, 17R, 18, 18B, 18P, 18R, 19, 19R, 20, 21, 22, 23, 24, 25, 26, 28, 29, 31A, 31B, 31C, 31D, 31E, 31F, 31G, 35, 36, 37, 39, 40, 52, 54 and 90; geometric tolerancing symbols for simple run-out (T_pl and T_RL) and the related datum are indicated on the drawings where values for these exist in this document;
• drawings for types 5, 7, 27, 38, 39 and 41 amended to show the geometric tolerancing symbols;
• new symbols for elevation of depressed centre (M), spindle diameter (S_d), spindle length (L₂) of mounted wheels and points, and internal radius of a segment (R₁) added;
• Table 18, a new row for the outside diameter D > 1 800 mm added giving the corresponding limit deviations and run-out tolerances;
• Table 20, the limit deviations of grinding wheel thickness for wheels with T, U ≤ 1,6 mm changed;
• Clause 5 added for general statements and requirements and Clause 13 added for mounted wheels and mounted points;
• normative reference to ISO 603 changed to be informative.

1 Scope
