UL Standard for Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use – Part 2-091: Particular Requirements for Cabinet XRay Systems
|Publication Date:||31 July 2019|
Equipment included in scope
This part of IEC 61010 specifies particular safety requirements for cabinet X-ray systems, which fall under any of categories a), b) or c) below.
Equipment covered by this document can be both PROTECTED EQUIPMENT or PARTIALLY PROTECTED EQUIPMENT, with X-ray generator voltage up to 500 kV.
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 prevent operator access to the radiation beam, during generation of X-radiation.
These cabinet X-ray systems are used in industrial, commercial, and public environments, for example, to inspect materials, to analyse materials, and to screen baggage.
Equipment excluded from scope
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:
- equipment intended to be used within a shielded room which excludes personnel during operation;
- equipment intended to be used with separate portable or temporary shielding;
- equipment intended to produce an emerging beam of X-radiation.
