This part of IEC 63093 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of pot-cores made of ferrite, and the dimensional limits for coil formers to be used with them, as well as effective parameter values to be used in calculations involving them. It also gives guidelines on allowable limits of surface irregularities applicable to pot-cores in accordance with the relevant generic specification.

The selection of core sizes and shapes for this standard is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry. See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included.

The general considerations upon which the design of this range of cores is based are given in Annex A.

This International Standard:

provides requirements and recommendations (see Note) for the overall Electrical Power System. In particular, it covers interruptible and uninterruptible Electrical Power Systems including the systems supplying the I&C systems;

is fully consistent and coherent with IEC 61513. Like IEC 61513, this standard also highlights the need for complete and precise requirements, derived from the plant safety goals. Those requirements are prerequisites for generating the comprehensive requirements for the overall I&C and Electrical Power System architecture, and for the electrical power supply sub-systems;

has to be considered in conjunction with and at the same level as IEC 61513. These two standards provide a complete framework establishing general requirements for instrumentation, control, and Electrical Power Systems for nuclear power plants.

Note: In the following, the word “requirement” is used as a comprehensive term for both requirements and recommendations. The distinction appears at the level of the specific provisions where requirements are expressed by “shall” and recommendations by “should.”

This International Standard establishes:

the high level specification and requirement to implement a suitable Electrical Power System in a NPP that supports reactor safety systems. It also enables electrical energy production providing the transmission grid with active, reactive power and electro-mechanical inertia;

the relationships between:

the plant safety requirements and the architecture of the overall Electrical Power System and its sub-systems (see Figure 1) including:

the contribution to the plant Defence in Depth;

the independency and redundancy provisions;

the electrical requirements and the architecture of the Electrical Power System and its sub-systems;

the functional requirements and the architecture of the Electrical Power System and its sub-systems;

the requirements associated with the maintenance strategy and the architecture of the Electrical Power System and its sub-systems;

the design of Electrical power sub-systems (e.g. interruptible and uninterruptible);

the requirements to supporting systems of Electrical Power System (HVAC, I&C, etc.);

the Electrical Power System life-cycle framework.

The standard does not cover the specification of:

I&C systems;

the transmission lines connecting to outdoor switchyards;

electrical equipment requirements already defined in the industrial IEC standards;

electrical power for security systems (e.g., fences, surveillance systems, entrance control);

lighting and socket facility.

This part of IEC 62024 specifies the measuring methods of the rated direct current limits for small inductors.

Standardized measuring methods for the determination of ratings enable users to accurately compare the current ratings given in various manufacturers’ data books.

This standard is applicable to leaded and surface mount inductors with dimensions according to IEC 62025-1 and generally with rated current less than 22 A, although inductors with rated current greater than 22 A are available that fall within the dimension restrictions of this standard (no larger than 12 mm ´ 12 mm footprint approximately). These inductors are typically used in DC to DC converters built on PCB, for electric and telecommunication equipment, and small size switching power supply units.

The measuring methods are defined by the saturation and temperature rise limitations induced solely by direct current.

IEC 62443‑2‑1 specifies asset owner security program (SP) requirements for an industrial automation and control system (IACS). This document uses the broad definition and scope of what constitutes an IACS as described in IEC 62443‑1‑1. In the context of this document, asset owner also includes the operator of the IACS.

This document recognizes that the lifespan of an IACS can exceed twenty years, and that many legacy systems contain hardware and software that are no longer supported. Therefore, the SP for a legacy system may address only a subset of the requirements defined in this document. For example, if its software is no longer supported, security patching requirements cannot be met. Similarly, backup software for older systems may not be available for all components of the IACS. As a result, this document recognizes that not all requirements can be met by legacy systems. In situations where specific requirements or subsets of requirements are applicable but unable to be implemented in legacy systems, then compensating countermeasures should be implemented where possible.

This document also recognizes that not all requirements specified in this document apply to all IACSs. For example, requirements associated with wireless technology or safety systems will not apply to IACSs that do not include wireless technology or safety systems technology. Similarly, malware protection requirements may not all apply to systems for which anti-malware software is not available for any of their devices. Therefore, the asset owner should identify the IACS security requirements that are applicable to its IACSs in their specific operating environments.

The elements of an IACS SP described in this document define required security capabilities that apply to the secure operation of an IACS. Although the asset owner is ultimately accountable for the secure operation of an IACS, implementation of these security capabilities often includes support from its service providers and product suppliers. For this reason, this document provides guidance for an asset owner when stating security requirements for their service providers and product suppliers, referencing other parts of the IEC 62443 series.

Figure 2 illustrates the 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. The Automation Solution is a technical solution implementing the functional capabilities necessary for the IACS. It is composed of hardware and software components that have been installed and configured to operate in the IACS. The IACS is a combination of the Automation Solution and the organizational measures necessary for its design, deployment, operation and maintenance.

Some of these capabilities rely on the appropriate application of integration maintenance capabilities defined in IEC 62443‑2‑4 [6] and technical security capabilities defined in IEC 62443‑3‑3 [10] and IEC 62443‑4‑2 [12].

This document provides technical-performance requirements, testing methods, requirements for operational performance and accompanying documents,  packaging, transportation and storage conditions for the system of spectral identification  of liquids in transparent and semitransparent containers (hereinafter referred to as  “system”) based on the method of inelastic (Raman) light scattering by molecules.

 

The standard applies both to stationary and hand-held systems – geometric and mass parameters are not concerned in the tests. The standard is applicable to substance  identification testing criteria as well as verification, approval and operating criteria of the system. Since the standard considers only the functionality of Raman analyzers and their ability to identify single- or multicomponent fluids, it is equally suitable for verifying the Raman analyzers assigned to security screening of threats, inspection of medical solutions, liquid chemicals, etc.

This International Standard defines requirements for component specificiations of electronic components that are intended for usage in surface mount technology. To this end, it specifies a reference set of process conditions and related test conditions to be considered when compiling component specifications.

The objective of this standard is to ensure that a wide variety of SMDs can be subjected to the same placement, mounting and subsequent (e.g. cleaning, inspection) processes during assembly. This standard defines tests and requirements that need to be part of any SMD component general, sectional or detail specification. In addition, this standard provides component users and manufacturers with a reference set of typical process conditions used in surface mount technology. 

Some of the requirements for component specifications in this standard are also applicable to components with leads intended for mounting on a circuit board. Cases for which this is appropriate are indicated in the relevant sub-clauses.
