Elevator Door Locking Devices and Contacts

In Canada, a Canadian Standard or Other Recognized Document is necessary for certification of products in regulated areas. In the case of elevating devices, elevator door locking devices require certification, as per ASME A17.1-2016/CSA B44-16 Elevator Code. Previously, these devices were certified using a CSA Technical Information Letter (TIL CSA D-11B). However, in May 2018, CSA withdrew TIL CSA D-11B. Accordingly, there are currently no requirements covering Elevator Door Locking Devices and Contacts in Canada. As a result, manufacturers and regulators are left with a requirement for certification but no Canadian standard or Other Recognized Document to meet that requirement. Manufacturers are currently producing product compliant with UL 104, an ANSI standard; UL 104 is referenced in the ASME A17.1-2016/CSA B44-16 Elevator Code. This Notice of Intent is to propose UL 104, the standard already used in the Canadian market for certification, as a joint Canada-US bi-national standard. In addition to manufacturer support, a joint Canada-US standard is supported by Dean Bruce, Provincial Administrator, Elevators, Amusement Rides and Passenger Ropeways, Municipal Affairs, Government of Alberta. Given the need for Canadian requirements, it is anticipated that a Joint Canada-US binational standard will also be supported by the RAAB and the Chair of CSA B44 committee. ANSI/ CAN/UL 104 will fill the gap in Canadian requirements for Elevator Door Locking Devices and Contacts and will assist manufacturing in meeting their obligation to produce certified products for use in Canada.
