This International Standard applies to the basic safety and essential performance of CT scanners, hereafter also referred to as me equipment.

If a clause or subclause is specifically intended to be applicable to me equipment only, or to me systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to me equipment and to me systems, as relevant.

NOTE 1 See also 4.2 of the general standard.

The scope of this document is limited to CT scanners intended to be used for head and/or body imaging characterised by an enclosure of the X-ray source(s) and imaging detector(s) in a common protective cover in the shape of a toroid. It includes safety requirements for the X-ray generators used in CT scanners, including those where high-voltage generators are integrated with an X-ray tube assembly.

NOTE 2 This standard does not intend to address interventional systems as described in IEC 60601-2-43 and cone-beam CT scanners integrated into a radiotherapy systems as described in IEC 60601-2-68 and dental cone-beam CT scanners as described in IEC 60601-2-63.

NOTE 3 The body includes cardiac, extremities, neck, etc.

The scope of this International Standard excludes radiotherapy simulators and systems where the image is created by a source other than an X-ray tube.

IEC 60601-1:2005+AMD1:2012, 1.1 is replaced by:

This document applies to the basic safety and essential performance of a clinical thermometer in combination with its accessories, hereafter referred to as ME equipment. This document specifies the general and technical requirements for electrical clinical thermometers. This document only applies to all electrical clinical thermometers that are used for measuring the temperature of patients.

This document is also applicable to those accessories intended by their manufacturer to be connected to the clinical thermometer, where the characteristics of those accessories can affect the basic safety or essential performance of the clinical thermometer.

EXAMPLE 1         Probes, probe cable extenders and probe covers.

Clinical thermometers can be equipped with interfaces to accommodate secondary indicators, printing equipment, and other auxiliary equipment to create ME systems. This document does not apply to auxiliary equipment.

ME equipment that measures the temperature of a patient is within the scope of this document.

EXAMPLE 2        ME equipment using accessories such as a pulmonary artery catheter for the determination of cardiac output by thermodilution is in the scope of this document if it displays a temperature.

EXAMPLE 3        ME equipment using accessories such as a Foley catheter that includes a temperature probe is in the scope of this document.

This document does not specify requirements for screening thermographs intended to be used for the individual non-invasive human febrile temperature screening of humans under indoor environmental conditions, whose laboratory accuracy requirements are described in IEC 80601‑2‑59[4].

If a clause or subclause is specifically intended to be applicable to ME equipment only, or to ME systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME equipment and to ME systems, as relevant.

Hazards inherent in the intended physiological function of ME equipment or ME systems within the scope of this document are not covered by specific requirements in this document except in IEC 60601‑1:2005+AMD1:2012, 7.2.13 and 8.4.1.
