Scope:

This Standard provides requirements for the design, construction, materials and testing of elevator buffers. This Standard covers buffers designed to stop a descending car or counterweight from travel beyond its normal limit by absorbing and dissipating the kinetic energy of the car or counterweight, including oil buffer and elastomeric buffer. The buffers covered in the Standard are intended for installation in passenger and freight elevator in accordance with ASME A17.1/CSA B44 Safety Code for Elevators and Escalators

Project need:

To create North American harmonized requirements that promote safe design of elevator buffers in order to reduce the risk of injury; To provide a uniform set of requirements for manufacturers throughout Canada and the US to demonstrate conformity; To facilitate adoption of uniform requirements by Canadian and US jurisdictions.
