requirements in the major world-wide lift codes and also the updating of ISO/TR 11071 (all parts) ISO/TR 11071 (all parts) represents a comprehensive comparison o f the major li ft prescriptive sa fety standards in use at the time of publication Since that time, there has been considerable harmonization and rationalization o f various standards with the result that there are currently three major sets o f prescriptive sa fety requirements in extensive use These are the CEN EN 81 series o f standards, the ASME A17 series/CSA B44 of standards, and the JIS TS A 0028-1 and the Building Standard Law of Japan (BSLJ) The goal of this document is to provide recommendations to assist national committees, when reviewing and revising individual standards, to initiate convergence towards harmonization of the technical requirements This document expands the list o f “agreed-upon points”, with a view to facilitate convergence o f key requirements o f the documents identified above In order to divide the work into manageable increments and set the priorities, it was deemed constructive to start with requirements for door locks, buffers, governors, safeties and brakes as the first step towards the complete li ft In order to expedite the convergence process, the recommendations have been prioritized to implement the harmonization o f requirements for sa fety components The priorities are ranked as follows: a) Priority 1, where the design o f sa fety components are directly a ffected; b) Priority 2, where the design o f systems or requirement language only are a ffected NOTE Priority includes items that should be harmonized first as it a ffects the design o f the components directly Priority includes items that should be harmonized at a later stage as it a ffects the system or language only The comparison of requirements in different parts of the world indicated the importance of good engineering practice in the implementation o f standards with regard to sa fety It was concluded that guidance on good engineering practice was necessary and it would be best to provide this guidance in ISO/TS 22559-2, the scope of which covers this issue It is important that this document be read in conjunction with ISO/TS 22559-2 This document was prepared by the Task Force on Convergence (TFC) and is based on in formation and input provided by the code study groups from Europe (EUCSG), North America (NACSG) and Japan (JPCSG) A fter in-depth analysis o f di fferences and rationale, the code study groups have agreed and formulated actions to be implemented in the course of development or revisions of standards in their respective regions Completion of those actions will result in harmonization of code requirements for door locks, bu ffers, governors, sa feties and brakes and will facilitate free circulation o f those sa fety components around the world This document is intended for use by standard writers in order to implement the prescriptive recommendations when developing or revising standards © ISO 2016 – All rights reserved I n tern ati o n al Org an i z ati o n fo r S tan d ard i z ati o n v I n tern ati o n al Org an i z ati o n fo r
