UL Provides Key Functional Safety Certification for the Elevator Industry

March 31, 2011
 

ASME A17.1 covers the design, construction, operation, inspection, testing, maintenance, alteration, and repair of the following equipment, its associated parts, and its hoistways, where located in or adjacent to a building or structure:
    - Hoisting and lowering mechanisms, equipped with a car or platform, which move between two or more landings. This equipment includes, but is not limited to, elevators.
    - Power-driven stairways and walkways for carrying persons between landings. This equipment includes, but is not limited to, escalators and moving walks.
    - Hoisting and lowering mechanisms equipped with a car that serves two or more landings and is restricted to the carrying of material by its limited size or limited access to the car. This equipment includes, but is not limited to, dumbwaiters and material lifts.

Underwriters Laboratories (UL) has actively participated in the ASME A17.1 technical committees (as well as the ISO TC 178 committee on the international level), putting it on the frontline in terms of exploring how risk management is handled relative to safety issues in the elevator industry. As such, UL has played a leading role in helping elevator manufacturers and their suppliers meet safety standard requirements.

“ASME A17.1:2007 requires a listing/certification mark for electrical protective devices and some other safety functions,” notes Anura Fernando, research engineer, predictive modeling and risk analysis, at UL. Because it requires third party marking when programmable electronics are employed, this standard represents a significant change: before this, manufacturers and Authorities Having Jurisdiction (AHJ’s) had to rely on self-certification by the manufacturer and avoidance of these technologies. Now they have an opportunity to leverage cutting-edge technologies with the assistance of Third Party certification.

UL provides a host of services to manufacturers and suppliers looking to meet the requirements of IEC 61508 per A17.1. These include:
    · A Functional Safety Listing Mark for ASME A17.1
    · A Functional Safety Recognized Component Mark for ASME A17.1
    · A three-year Functional Safety Certificate for ASME A17.1
    · Informative Test Reports for ASME A17.1
