It is identical with ISO
3、3098-5:1997. The UK participation in its preparation was entrusted by Technical Committee TDE/4, Engineering drawing, metrology and precision measurement and all related documentation, to Subcommittee TDE/4/-/1, General drawing principles, conventions and related documentation, which has the respons
4、ibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A lis

Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding European publ
6、ications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue.

Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover

The work of preparin
21、g 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 liai
22、son with 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. Publicatio
23、n as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO3098-5 was prepared by Technical Committee ISO/TC10, Technical drawings, product definition and related documentation, Subcommittee SC1, Basic conventions. ISO 3098 consists
