This International Standard defines the method to be followed for the determination of the X/Y coefficient of thermal expansion of electrical insulating materials by the use of a thermomechanical analyser (TMA).

This method is applicable to materials that are solid of the entire range of temperature used, and retain sufficient hardness and rigidity over the temperature range so that irreversible indentation of the specimen by the sensing probe does not occur.

This document describes the performance metrics associated with dual-energy imaging capable digital X-ray imaging devices meant for medical applications and specifies the methods for their determination. These metrics can be used to analyze tissue-subtracted images and to evaluate dose performance, noise characteristics, and tissue-subtraction efficacy of digital X-ray imaging devices. The described methods indicate the procedures to obtain multi-spectral primary data and to compute their derived tissue-subtracted images.

The intended users of this part of IEC 62220 are manufacturers and well-equipped test laboratories.  This document is restricted to digital X-ray imaging devices that are used for single or multiple exposure dual-energy radiographic imaging based on, for example, CR systems, direct and indirect flat panel-detector based systems.

This document excludes and is not applicable to:

digital X-ray imaging devices intended to be used in mammography or in dental radiography;

slot scanning digital X-ray imaging devices;

computed tomography or cone-beam computed tomography;

photon-energy discriminating devices such as photon counting X-ray imaging devices;

devices for dynamic imaging (where series of images are acquired, as in fluoroscopy or cardiac imaging).

digital X-ray imaging devices intended to be used with radiotherapy beams

Replacement:

This International Standard applies to the basic safety and essential performance of lens removal devices and vitrectomy devices for ophthalmic surgery (as defined in 201.3.208 and 201.3.217) and associated accessories that can be connected to this medical electrical equipment, hereafter 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.

Hazards inherent in the intended physiological function of me equipment or me systems within the scope of this standard are not covered by specific requirements in this standard except in 7.2.13 and 8.4.1 of the general standard.

NOTE See also 4.2 of the general standard.

This part of IEC 62443 specifies a comprehensive set of requirements for security capabilities for IACS service providers that they can offer to the asset owner during integration and maintenance activities of an Automation Solution. Because not all requirements apply to all industry groups and organizations, Subclause 4.1.4 provides for the development of Profiles that allow for the subsetting of these requirements.  Profiles are used to adapt this document to specific environments, including environments not based on an IACS.

NOTE 1 The term “Automation Solution” is used as a proper noun (and therefore capitalized) in this part of IEC 62443 to prevent confusion with other uses of this term.

Collectively, the security capabilities offered by an IACS service provider are referred to as its Security Program for IACS Asset Owners. In a related specification, IEC 62443-2-1 describes requirements for the Security Management System of the asset owner.

NOTE 2 In general, these security capabilities are policy, procedure, practice and personnel related.

Figure 1 illustrates the integration and maintenance security capabilities of the asset owner, service provider(s) and product supplier(s) of an IACS and their relationships to each other and to the Automation Solution. Some of the IEC 62443-2-4 security program requirements are associated with security requirements described in IEC 62443-3-3 and IEC 62443-4-2.

NOTE 3 The IACS is a combination of the Automation Solution and the organizational measures necessary for its design, deployment, operation, and maintenance.

NOTE 4 Maintenance of legacy system with insufficient security functional capabilities, implementation of policies, processes and procedures are recommended as risk mitigations.

This part of IEC 61987 provides

an operating list of properties (OLOP) for the description of the operating parameters and the collection of requirements for I/O modules and

a device list of properties (DLOP) for the description of a range of I/O module types

The structures of the OLOP and the DLOPs correspond to the general structures defined in IEC 61987-11 and agree with the fundamentals for the construction of LOPs defined in IEC 61987-10.

Aspects other than the OLOP, needed in different electronic data exchange processes and described in IEC 61987-10 and IEC 61987-11, are published in IEC 61987-92.

The locations of the libraries of properties and of blocks used in the LOPs concerned are listed in the Annexes C and D.

This Standard describes electrical and mechanical requirements of single-phase Station Service Voltage Transformers with voltages of 34.5 kV or higher in the highest voltage winding.

This standard is a basis for the establishment of performance and limited electrical and mechanical interchangeability requirements of the equipment are described. It is also a basis for assistance in the proper selection of such equipment.

A station service voltage transformer (SSVT) is a single-phase transformer to be connected line-to-earth on an effectively earthed system. It can be used either as an individual unit for supplying single-phase loads, or in a three-phase bank to support three-phase loads.  A typical application is to supply substation power such as lighting, pump and motor loads. The SSVT is provided with a measuring winding when requested by the user.
