ASME A17.1-2010/CSA B44-10

This is the second edition of ASME A17.1/CSA B44, Safety Code for Elevators and Escalators. It
replaces the previous edition of ASME A17.1/CSA B44, published in 2007, and the previous
editions of CSA B44, published in 2004, 2000, 1994, 1990, 1985, 1975, 1971, 1966, 1960, and 1938.
This Code is the result of a joint effort by the CSA B44 Technical Committee on the Elevator Safety
Code and the ASME A17 Committee on Elevators and Escalators to harmonize the provisions of
CSA B44 and ASME A17.1. This edition of ASME A17.1/CSA B44 consists of the complete
ASME A17.1 Code, with additional requirements applicable only in Canadian jurisdictions. These
Canadian requirements are prefaced in the body of the Code by the following: “In jurisdictions
enforcing the NBCC. . .”
CSA B44 was originally developed to facilitate the implementation of uniform legislation across
Canada and to replace the existing legislation, which had proved inadequate for prevailing
elevator practices. The primary purpose of the Code is to establish minimum requirements,
suitable for adoption by regulatory authorities throughout Canada, for the design, installation,
and maintenance of elevators, escalators, dumbwaiters, moving walks, and material lifts. It is
also intended as a standard reference for architects, consulting engineers, elevator manufacturers,
and building owners.
This Code is considered suitable for use for conformity assessment within the stated scope of
the Code.
This Code was prepared for use in Canada by the CSA Technical Committee on the Elevator
Safety Code under the jurisdiction of the CSA Strategic Steering Committee on Mechanical
Industrial Equipment Safety. It has been formally approved by the CSA Technical Committee.
