The work of preparing International Standards is normally
11、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 wo
12、rk. 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 diff
13、erent 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 ma

32、f the lens cylinder or a spherical surface).Note 2 to entry: As datum features are subject to manufacturing imperfections and variations, it could be necessary, where appropriate, to specify tolerances of form to them (see ISO 5459).SOURCE: ISO 5459:2011, 3.2, modified Note 1 and Note 2 from ISO 545
