10、v ISO 2001 All rights 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 intere
11、sted 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 International Electrotechnical
12、Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication
13、 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such
14、patent rights. International Standard ISO 7465 was prepared by Technical Committee ISO/TC 178, Lifts, escalators, passenger conveyors. This third edition cancels and replaces the second edition (ISO 7465:1997), which has been technically revised. Copyright International Organization for Standardizat

16、ts Guide rails for lift cars and counterweights T-type 1Scope This International Standard specifies the grades and quality, the dimensional characteristics and tolerances, and the surface finish of standardized guide rails and their fishplates. The dimensional tolerances include the tolerances on sh
17、ape and dimensions, straightness, twisting and perpendicularity defects. In addition, 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 ca

In this International Standard, the manufacturing process for each type of guide is indicated by the letter A for cold drawn, B for machined and
33、BE for machined, high quality. The tensile strength of the steel raw material used shall be at least 370 N/mm2and not more than 520 N/mm2. For this purpose, it is recommended to use steel grade E235B for cold drawn guides and steel grade E275B for machined guides, in accordance with ISO 630:1995. 6G
