24、266:2010ISO 3266:2010(E) iv ISO 2010 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees
25、. 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 work. ISO collaborates closely with the Intern
26、ational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Sta
27、ndards 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. Attention is drawn to the possibility that some of the elements of this document may be the subj
28、ect of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3266 was prepared by Technical Committee ISO/TC 111, Round steel link chains, chain slings, components and accessories, Subcommittee SC 3, Components and accessories. This second edition cancel
29、s and replaces the first edition (ISO 3266:1984), which has been technically revised.

33、onal Standard specifies the general characteristics, performance and critical dimensions necessary for interchangeability and compatibility with other components, of forged steel eyebolts grade 4 for general lifting purposes. These eyebolts can be used for axial and inclined loading. This Internatio
34、nal Standard specifies the dimensions of the eyes of eyebolts permitting direct connection with shackles of the same working load limit as those defined in ISO 2415. These dimensions also allow designs with a larger eye which can permit direct connection with sling hooks of similar working load limi
35、t. This International Standard covers all significant hazards, hazardous situations and events relevant to eyebolts grade 4 as defined in Clause 4. This International Standard is applicable to eyebolts grade 4 for use in the temperature range of 20 C to 200 C. This International Standard is not appl
36、icable to eyebolts which are not forged in one piece. This International Standard is not applicable to forged steel eyebolts grade 4 manufactured before the date of its publication as an International Standard. 2 Normative references The following referenced documents are indispensable for the appli
