Safety requirements for electrical equipment for measurement, control, and laboratory use — Part 2-091: Particular requirements for cabinet X-ray systems

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

1.1 Scope

1.1.1 Equipment included in scope

Deletion:

Delete the first paragraph.

Replacement:

Replace the second paragraph (above items a) to c)) with the following new text:

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.

Addition:

Add the two following new paragraphs at the end of the subclause:

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.

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 Object

1.2.1 Aspects included in scope

Addition:

Add the following new text to 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.
