The work of preparing Internation

8、al 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,

9、 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

10、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. www.iso.org/directivesAttention is drawn to the possibility that some of the elements

11、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. ww

The committee responsible for this document is ISO/TC 112, Vacuum technology.This first edition of ISO 2861 cancels and replaces 2861-1:1974, of which it co

13、nstitutes a technical revision. The most important change is the addition of the dimension for 50 mm nominal bore quick-release couplings and their constituent parts to the dimensions of the four nominal bore sizes, 10 mm, 16 mm, 25 mm and 40 mm, already specified in the replaced standard (ISO 2861-
