30、on of the equipment in other than traditional locations such as machinerooms. The ASME A17 Standards Committee opened a technical revision in 1997 to fully addressthe safety issues regarding such installations and subsequently formed an Ad Hoc Committeeto formulate the proposal. The Ad Hoc Committee

31、, which was bi-national with nearly equalmembership from both the United States and Canada, developed the requirements necessary toaddress the safety aspects of the installation of equipment whether it is located in traditionalmachine rooms, control rooms, or in machinery spaces and control spaces i

32、nside and outside thehoistway. Over a period of 6 years the revisions were refined by the Ad-Hoc Committee and theA17 Standards Committee through the ASME/ANSI consensus process.The revisions contained in this Supplement went through numerous ballots to all of the membersof the A17 Standards Committ

33、ee (Hoistway, Electrical, Mechanical Design, Hydraulic, and Emer-gency Operations committees) as well as the National Interest Review Group, the RegulatoryAdvisory Council, and the CSA B44 Technical Committee in order to achieve consensus by all.This Supplement to the ASME A17.12004 Code is the resu

34、lt of that work.The revisions contained in this Supplement do not apply to all equipment covered by A17.1Code at this time. The revisions in this Supplement apply to new installations of electric elevatorsand hydraulic elevators within the Scope of ASME A17.12004. This Supplement has been harmo-nize

35、d with ASME A17.1a2005 and replaces the requirements of Parts 2 and 3 in its entirety, andmodifies the definitions of Part 1 as well as the requirements of Part 8 as shown in the Supplement.This Supplement does not apply to equipment covered by the Scopes of Parts 4, 5, 6, and 7 ofASME A17.12004 inc

36、luding A17.1a2005, and all references within these Parts are to the require-ments in ASME A17.12004 including A17.1a2005, not to the requirements in this Supplement.The requirements are being released as a special Supplement to the ASME A17.12004 Codeat the request of industry and the A17 Standards
