11、 reserved Foreword 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. Each member body interested in a subject for
12、 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 International Electrotechnical Commission (IEC) on a
13、ll 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 Standards adopted by the technical committees are
14、 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 subject of patent rights. ISO shall not be held re
15、sponsible for identifying any or all such patent rights. ISO 7465 was prepared by Technical Committee ISO/TC 178, Lifts, escalators and moving walks. This fourth edition cancels and replaces the third edition (ISO 7465:2001), which has been technically revised. Copyright International Organization f

17、lifts and service lifts Guide rails for lift cars and counterweights T-type 1 Scope This International Standard specifies the grades and quality, the dimensional characteristics, the dimensional and geometrical tolerances, and the surface finish of standardized guide rails and their fishplates. In a
18、ddition, this International Standard defines a designation system for guide rails. This International Standard is applicable to guide rails used in passenger lift and service lift installations to provide guiding for the car and the counterweight. 2 Normative references The following referenced docu

In this International St
32、andard, the manufacturing process for each type of guide is indicated by the symbol /A for “cold drawn”, the symbol /B for “machined”, and the symbol /BE for “machined high quality”. The tensile strength of the raw material used (steel) shall be at least 370 N/mm2 and not more than 520 N/mm2. For th
33、is purpose, it is recommended to use steel grade E 235 B for cold-drawn guide rails and steel grade E 275 B for machined guides, in accordance with ISO 630:1995. 6 Guide rails 6.1 Designation Guide rails complying with the requirements of this International Standard shall be designated as follows: 1
34、st element: Number of this International Standard, followed by a hyphen: ISO 7465-; 2nd element: Guide rail shape: T; 3rd element: Rounded value of the foot width with, if necessary, the number of the variant for different profiles with the same foot width: 45; 50; 70; 75; 78; 82; 89; 90; 114; 125;
