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.

This document establishes the requirements for instrumentation needed to detect leakage from reactor coolant systems of all types of light water and heavy water nuclear reactors. Methods of leakage detection are described and characteristics of different methods of detection and of differentiating between allowable and abnormal leakages are given.

The sensitivity of systems required to ensure early detection of developing leaks and to give warning of possible leak-before-break situations is considered, and recommendations are given to reduce spurious alarms. Same requirements apply in case of the break preclusion concept or other concepts for the assurance of components’ and pipes’ integrity.

Recommendations are given for data display which will allow presentation in a clear and concise manner to enable operators to take appropriate actions to minimize the risk of hazard to plant equipment and to personnel. Requirements are given for recording and logging, as well as for summation of individual signals to detect trends.

The objective of this document is to define the requirements for leakage detection data, for arranging it in a logical manner, and for displaying information to enable the operator to take appropriate action. A secondary objective of this document is to standardize criteria, methods and procedures for assuring the design and operational adequacy of the reactor coolant and associated systems (RCAS) leakage detection systems used in light water and heavy water nuclear reactors.

This document

·    gives guidance on the functional requirements, operational requirements, reliability requirements and test requirements of the electronic tagging system;

·    specifies the core functions of the electronic tagging system, including recording information on the material in the container, locating the position of the container, and transmitting information to the control centre.

This document is applicable to the electronic tagging system used for tracking radioactive materials,with the aim of facilitating the tracking of radioactive materials and improving safety during their transportation.

This document specifies the requirements for evaluating CPV/PV hybrid module performance in terms of power rating. Standard conditions for assessing the power produced by the module and the procedures to measure the power as a function of AOI, irradiance, and temperature are defined. A methodology for determining a set of characterization parameter values for the hybrid CPV/PV module (FoV) is also included. In order to compare the performance of different hybrid CPV/PV modules whose output is discontinuous and time-dependent the concept of effective nominal power is introduced. This standard is written to be applicable to CPV/PV hybrid modules which include both solar cells designed to collect concentrated light (CPV cells array) and solar cells designed to collect diffuse or global light (PV cells array), the last ones, with bifacial or monofacial illumination. This document applies for hybrid CPV/PV modules with geometrical concentration ratio >3x to CPV cells. For lower geometrical concentration ratio (≤ 3x), the IEC 60904-1 and IEC 61853 series apply.

Amendment

The purpose of this part of IEC 61300 is to describe the procedure required to measure the spring compression force of the coupling sleeve for rectangular ferrule multi-fibre connectors.

This part of IEC 63567-1 proposes a method of measuring the transmittance of extreme ultraviolet (EUV) pellicle used for extreme ultraviolet lithography (EUVL) and provides guidelines on the conditions of the transmittance measurement instrument using EUV with a short wavelength and methods for calculating EUV transmittance.

The scope of this document applies to all types of membranes attached to the front side of a reflective mask (or reflective reticle) used in EUVL to physically protect the reflective mask from contaminant particles generated inside the chamber during EUV exposure.

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.
