It
3、 is identical with ISO 10512:1997. The UK participation in its preparation was entrusted by Technical Committee FME/9, Bolts, nuts and accessories, to Subcommittee FME/9/10, Male and female prevailing torque fasteners, which has the responsibility to: aid enquirers to understand the text; present to
4、 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 list of organizations represented on this subcommittee can be o
5、btained on request to its secretary. 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 publications. The British Standards which implement these int
6、ernational 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. A British Standard does not purport to include all the necessary provi
7、sions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

20、ies). The work of preparing 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
21、 non-governmental, in liaison 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 bod
22、ies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 10512 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 1, Mechanical properties of fasteners. Annex A of this Internatio
23、nal Standard is for information only. Descriptors: Fasteners, fine pitch threads, nuts (fasteners), self-locking nuts, hexagonal nuts, specifications, dimensions, designation. EN ISO 10512:1997 BSI 05-19991 1 Scope This International Standard specifies the characteristics of prevailing torque type h
24、exagon nuts (with non-metallic insert), style 1, with metric fine pitch thread with nominal thread diameters d from 8 mm up to and including 36 mm, in product grade A for sizes d up to and including 16 mm and product grade B for sizes d above 16 mm, and with property classes 6, 8 and 10. NOTEThe dim
25、ensions of the nuts correspond to those given in ISO 8673 plus prevailing torque feature. If other specifications are required, they should be selected from existing International Standards, for example ISO 261, ISO 965-2, ISO 2320 and ISO 4759-1. 2 Normative references The following standards conta
