What code regulates elevator installations in the U.S.?

The regulation of elevator installations in the U.S. is governed by ASME A17.1, which is the Code for Safety and Maintenance of Elevators and Escalators. This code outlines essential safety requirements for the design, construction, installation, operation, inspection, testing, maintenance, and repair of elevators, escalators, moving walks, and other conveying systems.

ASME A17.1 is crucial in ensuring that elevators are safe for public use, providing guidelines that help prevent accidents and malfunctions. It is recognized and adopted by various states and local jurisdictions, thereby serving as a standard reference for elevator manufacturers, installers, and inspectors.

The other options presented do not pertain to elevator regulations. ISO 9000 relates to quality management systems, ANSI A117.1 addresses accessibility standards, and NEC 70, also known as the National Electrical Code, covers electrical installations but does not specifically regulate elevators. Understanding the specific codes applicable to elevator installations is essential for compliance and safety in the field.
