Preface
This is the first edition of CSA B44.9/ASME A17.9, Elevator buffers. The purpose of this Standard is to provide requirements for elevator buffers primarily for conformity assessment purposes. This Standard arose from the need to have identical Canadian and U.S. requirements for this equipment, thereby enabling manufacturers to have their products approved for use in Canada or the United States. Users of this Standard are reminded that additional and site-specific requirements may be specified by federal, provincial/territorial, state, municipal, local, or other authority, or by a project owner. This Standard should not be considered a replacement for the requirements contained in any a) applicable federal, state, provincial, or territorial statute; b) regulation, license, or permit issued pursuant to an applicable statute; or c) contract that any owner has with a contractor. This Standard was prepared by the CSA/ASME Joint Subcommittee on Elevator Buffers, under the jurisdiction of the CSA Technical Committee on the Elevator Safety Code, the CSA Strategic Steering Committee on Mechanical and Industrial Equipment Safety, and the ASME A17 Standards Committee. It is the intent of these committees to maintain a single harmonized Standard by coordinating their procedures for revising and interpreting this Standard. To this end, interpretations and revisions of this Standard will not be issued without the approval of both the CSA Technical Committee on the Elevator Safety Code and the ASME A17 Standards Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard.
Scope
1.1 Inclusions
This Standard covers mechanical requirements of construction, marking, and type testing requirements for oil buffers and elastomeric buffers intended to be installed in passenger and freight elevators in accordance with ASME A17.1/CSA B44.
1.2 Exclusions
This Standard does not cover spring buffers or electrical components as part of the buffer assemblies.
1.3 Dual measurements
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
1.4 Terminology
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements.
