9、 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
10、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 matter
11、s 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 docu
12、ment 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 s
13、uch 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 d
14、oes not constitute an endorsement.

This third edition cancels and replaces the second edition (ISO 8051:1999), of which it constitutes a minor revision with the followin
16、g change: addition of Annex A, which gives the relationship between the designations of this International Standard and the ISO 13399 series.iv ISO 2016 All rights reservedBS ISO 8051:2016INTERNATIONAL ST ANDARD ISO 8051:2016(E) Long shank taps with nominal diameters from M3 to M10 Full-diameter sha
17、nk taps with recess 1 Scope This International Standard specifies the dimensions for full-diameter shank taps with recess with nominal diameters from M3 to M10 and thus complements ISO 2283, which concerns relieved shank taps. It applies to long shank machine taps. Technical specifications for taps
18、covered by this International Standard (including marking) are given in ISO 8830. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For unda
19、ted references, the latest edition of the referenced document (including any amendments) applies. ISO 529:1993, Short machine taps and hand taps ISO 8830:1991, High-speed steel machine taps with ground threads Technical specifications 3 Dimensions Dimensions are given in Figure 1 and Table 1. The th
20、readed lengths of these taps are in accordance with those given in ISO 529. Shank lengths (L l) are increased by 50 % with respect to those given in ISO 529; total lengths therefore vary accordingly. NOTE Annex A gives the relationship between the designations of this International Standard and ISO
