APPLICATION OF THIS SUPPLEMENT
(This is a special Supplement to the ASME A17.1-2004 Code.)
The advancement of technologies used in the design and construction of elevator equipment
has enabled the installation of the equipment in other than traditional locations such as machine
rooms. The ASME A17 Standards Committee opened a technical revision in 1997 to fully address
the safety issues regarding such installations and subsequently formed an Ad Hoc Committee
•
to formulate the proposal. The Ad Hoc Committee, which was bi-national with nearly equal
membership from both the United States and Canada, developed the requirements necessary to
address the safety aspects of the installation of equipment whether it is located in traditional
machine rooms, control rooms, or in machinery spaces and control spaces inside and outside the
hoistway. Over a period of 6 years the revisions were refined by the Ad-Hoc Committee and the
AI7 Standards Committee through the ASME/ ANSI consensus process.
The revisions contained in this Supplement went through numerous ballots to all of the members
of the A17 Standards Committee (Hoistway, Electrical, Mechanical Design, Hydraulic, and Emer
gency Operations committees) as well as the National Interest Review Group, the Regulatory
Advisory Council, and the CSA B44 Technical Committee in order to achieve consensus by all.
This Supplement to the ASME AI7.I-2004 Code is the result of that work.
The revisions contained in this Supplement do not apply to all equipment covered by A17.1
Code at this time. The revisions in this Supplement apply to new installations of electric elevators
•
and hydraulic elevators within the Scope of ASME AI7.1-2004. This Supplement has been harmo
nized with ASME AI7.Ia-2005 and replaces the requirements of Parts 2 and 3 in its entirety, and
modifies 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 of
ASME AI7.I-2004 including AI7.Ia-2005, and all references within these Parts are to the require
ments in ASME AI7.I-2004 including A17.1a-200S, not to the requirements in this Supplement.
The requirements are being released as a special Supplement to the ASME AI7.I-2004 Code
at the request of industry and the AI7 Standards Committee.
