A17.3 guides all parties engaged in the safe installation, inspection, testing, operation, and/or insurance of existing elevators and escalators; thus sparing the major capital expense of all-new equipment. As an alternative to ASME A17.1-2010, it also allows for more flexibility in problem-solving. This Code is to be used in conjunction with other volumes of ASME?s A17 series of safety standards. Careful application of these A17 safety standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational and safety benefits to be gained from the many industry best-practices detailed within these volumes.
