Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use – Part 2-091: Particular Requirements for Cabinet X-Ray Systems

UL 61010-2-091 (IEC 61010-2-091:2012)

1 Scope and object

This clause of Part 1 is applicable, except as follows:

1.1.1 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.

1.1.2 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:

• 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.

1.2.1 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.
