ASME A17。1/CSA B44，《电梯和自动扶梯安全规范》和ASME A17。7/CSA B44。7《电梯和自动扶梯基于性能的安全规范》是公认的电梯、电梯服务员、自动扶梯、自动人行道和物料升降机的设计、施工、安装、操作、检查、测试、维护、改造和维修指南。它们是美国和加拿大使用的全部或部分电梯代码的基础。ASME A17。1/CSA B44和ASME A17。7/CSA B44。7仅为指南，除非有管辖权的机构将其作为法律或法规采用。 除ASME A17中的要求外，当地司法管辖区可能会在其通过的立法中偶尔修订和/或纳入其他要求。1/CSA B44和ASME A17。7/CSA B44。7.因此，在任何地区应用规范要求之前，建议与当地司法机构进行核实。ASME A17修订了要求1.1.1（c）。1-2013/CSA B44-13，以澄清本规范不包括带有升降机构的装置，该装置配备有一辆服务于两个或两个以上平台的轿厢，且仅限于搬运材料，但未被归类为哑铃或材料升降机。 要求1.1.2概述了ASME A17未涵盖的设备示例。1/CSA B44和ASME A17。7/CSA B44。7.要求1.1.3规定了本规范中仅适用于新装置的部分和要求，以及适用于新装置和现有装置的部分和要求。ASME A17修订了要求1.1.3。1-2019/CSA B44:19包括第8.12节，因为国际建筑规范要求现有建筑在某些条件下符合ASCE 24，这些条件反过来会影响现有建筑中安装的新电梯和现有电梯。

ASME A17.1/CSA B44, Safety Code for Elevators and Escalators, and ASME A17.7/CSA B44.7, Performance- Based Safety Code for Elevators and Escalators, are the accepted guides for design, construction, installation, operation, inspection, testing, maintenance, alteration,and repair of elevators, dumbwaiters, escalators, moving walks, and material lifts. They are the basis in total or in part for elevator codes used throughout the United States and Canada.ASME A17.1/CSA B44 and ASME A17.7/CSA B44.7 are only guides unless adopted as law or regulation by an authority having jurisdiction. Local jurisdictions may, in their adopting legislation, occasionally revise and/or include requirements in addition to those found in ASME A17.1/CSA B44 and ASME A17.7/CSA B44.7. It is therefore advisable to check with the local jurisdiction before applying code requirements in any area.Requirement 1.1.1(c) was revised in ASME A17.1- 2013/CSA B44-13 to clarify that devices with hoisting and lowering mechanisms equipped with a car serving two or more landings and restricted to the carrying of materials but not classified as a dumbwaiter or material lift are not covered by the Code.Requirement 1.1.2 outlines examples of equipment not covered by ASME A17.1/CSA B44 and ASME A17.7/CSA B44.7. Requirement 1.1.3 specifies those Parts and requirements of the Code that apply only to new installations, as well as those that apply to both new and existing installations. Requirement 1.1.3 was revised in ASME A17.1-2019/CSA B44:19 to include Section 8.12 because the International Building Code requires existing buildings to comply with ASCE 24 under certain conditions that would in turn affect new and existing elevators installed in an existing building.
