CSA Group CSA B44.11:23 Elevator door locking devices and door or gate closed detection means

PREFACE

This is the harmonized CSA Group and ULSE Standard for Elevator Door Locking Devices and Door orGate Closed Detection Means. It is the First edition of CSA B44.11 and the Twelfth edition of UL 104. This edition of CSA B44.11 replaces CSA LTR D-001, published in 2018. This edition of UL 104 supersedes the previous edition(s) published on February 26, 2016.

This harmonized standard was prepared by the CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Joint Technical Subcommittee (JTSC) for the Standard for Elevator Door Locking Devices and Contacts are gratefully acknowledged.

This standard is considered suitable for use for conformity assessment within the stated scope of the standard.

This standard was reviewed by the CSA Subcommittee on Elevator Door Locking Devices and Contacts, under the jurisdiction of the CSA Technical Committee on Elevator Safety Code and the CSA Strategic Steering Committee on Mechanical Industrial Equipment Safety, and has been formally approved by the CSA Technical 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.

Application of the Standard

Where reference is made to a specific number of samples to be tested, the specified number is to be considered a minimum quantity.

Note: Although the intended primary application of this standard is stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of Harmonization

This standard is published as an identical standard for CSA Group and ULSE. An identical standard is a standard that is exactly the same in technical content except for national differences resulting from conflicts in codes and governmental regulations. Presentation is word for word except for editorial changes.

Interpretations

The interpretation by the standards development organization of an identical or equivalent standard is based on the literal text to determine compliance with the standard in accordance with the procedural rules of the standards development organization. If more than one interpretation of the literal text has been identified, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reflect the intent.

Notes:

1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.

2) This Standard contains SI (Metric) units. (Standard for use of the International System of Units (SI): The Modern Metric System, IEEE/ASTM SI 10 or ISO 80000-1:2009 Quantities and units – Part 1: General are used as a guide in making metric conversion from yard/pound quantities.) If a value for a measurement and a corresponding value in other units are stated, the first stated value to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both shall be provided.

3) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose

4) This Standard was developed by consensus, which is defined by CSA Policy governing standardization – Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Standard.

5) To submit a request for interpretation of this Standard, please send the following information to [email protected] and include “Request for interpretation” in the subject line:

a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;

b) provide an explanation of circumstances surrounding the actual field condition; and

c) where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.

Committee interpretations are processed in accordance with the CSA Directives and Guidelines governing standardization and are available on the Current Standards Activities page at standardsactivities.csa.ca
