24、 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 which a technical committee has been established has the right to be represented on that committee. International organiza
25、tions, governmental and 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. International Standards are drafted in accordance with the rules given in t
26、he 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 circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of
27、 the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between tech
28、nical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publicatio
29、n if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, i
30、t is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. 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 responsible for ide
31、ntifying any or all such patent rights. ISO/TS 25740-1 was prepared by Technical Committee ISO/TC 178, Lifts, escalators and moving walks. ISO/TS 25740 consists of the following parts, under the general title Safety requirements for escalators and moving walks: Part 1: Global essential safety requir
32、ements (GESR) Future parts will address safety parameters for escalators and moving walks. DD ISO/TS 25740-1:2011ISO/TS 25740-1:2011(E) vi ISO 2011 All rights reservedIntroduction After the publication of ISO/TR 14799-1 and ISO/TR 14799-2, discrepancies were noted in the safety standards for escalat
33、ors and moving walks. A need for the establishment of global essential safety requirements (GESR) for escalators and moving walks was identified, which resulted in the publication of ISO 14798. This methodology was a critical tool in the development of this Technical Specification on safety requirem
34、ents for escalators and moving walks. The objective of this Technical Specification is to: a) define a common global level of safety for all people using, or associated with, escalators and moving walks; b) facilitate innovation of escalators and moving walks not designed according to existing local
35、, national or regional safety standards, while maintaining equal levels of safety (if such innovations become state of the art, they can then be integrated into the detailed local safety standard at a later date); c) remove trade barriers. NOTE ISO/TS 25740-2 will contain global essential safety par
36、ameters (GESPs) for escalators and moving walks that should further assist in the use and implementation of the GESRs specified in this part of ISO/TS 25740. Clause 4 gives the approach and methodology used in the development of this part of ISO/TS 25740. Clause 5 gives instructions for the use and
37、implementation of GESRs. The GESRs are given in Clause 6. Each GESR specifies a safety objective, i.e. what is to be achieved rather than how to do it, in order to allow innovation and development of future technologies. Annex A gives an overview of GESRs in relation to subsystems of escalators and
38、moving walks. Annex B demonstrates compliance of this document with the European Directive for Machinery 2006/42/EC. This part of ISO/TS 25740 is a basic safety standard according to the principles given in ISO/IEC Guide 51. DD ISO/TS 25740-1:2011TECHNICAL SPECIFICATION ISO/TS 25740-1:2011(E) ISO 20
39、11 All rights reserved 1Safety requirements for escalators and moving walks Part 1: Global essential safety requirements (GESR) 1 Scope This part of ISO/TS 25740: specifies global essential safety requirements (GESRs) for escalators and moving walks, their components and functions, and establishes a
40、 system and provides methods for minimizing safety risks that might arise in the course of the operation and use of, or work on, escalators and moving walks. NOTE See Clause 5 regarding the use and application of this part of ISO/TS 25740. This part of ISO/TS 25740 is applicable to escalators and mo
41、ving walks that are intended to carry persons. The escalators and moving walks to which this part of ISO/TS 25740 applies can: a) be located in any permanent and fixed structure or building; b) have any 1) rated load, size of load carrying unit (LCU) and speed, and 2) travel height; c) be affected b
42、y fire in the environment of the LCU and weather conditions; d) be misused. This part of ISO/TS 25740 does not specifically cover: all needs of users with disabilities1); risks arising from work on escalators and moving walks under construction or during alterations and dismantling; vandalism; fire
43、in the environment outside the LCU. 1) Although the GESRs specified in this part of ISO/TS 25740 have been identified and evaluated by risk assessment, not all disabilities or combinations of such disabilities of users have necessarily been addressed.
