Maintenance Requirements and Intervals for Elevators, Dumbwaiters, Escalators, and Moving Walks
This is the first edition of CSA B44.2, Maintenance requirements and intervals for elevators, dumbwaiters, escalators, and moving walks. The material contained in this Standard was previously published as Appendix J of CSA B44, Safety code for elevators and escalators.
This Standard specifies maintenance requirements and service intervals for elevators, dumbwaiters, escalators, and moving walks where the original manufacturer's recommendations are not available or where there is insufficient data on the age, quality, and operation of the equipment.
This Standard is intended for use in conjunction with ASME A17.1/CSA B44.
In CSA Standards, 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; may is used to express an option or that which is permissible within the limits of the standard; and can is used to express possibility or capability. 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. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
