The work of preparing Int
9、ernational 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 w
10、ith ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as
11、an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO11882 was prepared by Technical Committee ISO/TC172, Optics and optical instruments, Subcommittee SC 5, Microscopes and endoscopes.iv blankBS7012-13:1997 BSI 09-1999 1 1 Scope Th
