UL Standard for Safety Requirements for Electrical Equipment for Measurement@ Control@ and Laboratory Use – Part 2-091: Particular Requirements for Cabinet X-Ray Systems (COMMENTS DUE: JULY 21@ 2014)
Equipment included in scope Replacement: Replace the text with the following: A CABINET X-RAY SYSTEM is a system that contains an X-ray tube installed in a cabinet which@ independently of existing architectural structures except the floor on which it may be placed@ is intended to contain at least that portion of a material being irradiated@ provide radiation attenuation@ and exclude personnel from the interior during generation of X-radiation. These CABINET X-RAY SYSTEMS are used in industrial@ commercial@ and public environments@ for example@ to inspect materials@ to analyze materials@ and to screen baggage. Equipment excluded from scope Addition: Add the following new items to the list: aa) equipment intended to apply X-radiation to humans or animals; bb) equipment incorporating an X-ray tube but not incorporating complete shielding against X-radiation hazards@ such as: 1) equipment intended to be used within a shielded room which excludes personnel during operation; 2) equipment intended to be used with separate portable or temporary shielding; 3) equipment intended to produce an emerging beam of X-radiation. Aspects included in scope Addition: Add the following text at the end of the first paragraph: This part of IEC 61010 specifies requirements for the design and methods of construction of CABINET X-RAY SYSTEMS to provide adequate protection for OPERATORS@ bystanders@ trained service personnel@ and the surrounding area against unintentionally-emitted X-radiation and from mechanical HAZARDS related to their conveyors.
