The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (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 an International Standard requires approval by at least 75 % of the member bodies casting a vote.International Standard ISO 15071 was prepared by Technical Committee ISO/TC 2, Fasteners.Annex A forms an integral part of this International Standard.标准分享网 w w w .b z f x w .c o m 免费下载INTERNATIONAL STANDARD ISOISO 15071:1999(E)1Hexagon bolts with flange Small series Productgrade A1 ScopeThis International Standard specifies the characteristics of hexagon bolts with flange, small series, with productgrade A, with threads from M5 up to and including M16 and property classes 8.8, 9.8, 10.9 and A2-70.If, in special cases, specifications other than those listed in this International Standard are required, they should beselected from existing International Standards, for example ISO 261, ISO 888, ISO 898-1, ISO 965-2, ISO 3506-1.2 Normative referencesThe following standards contain provisions which, through reference in this text, constitute provisions of thisInternational Standard.
