This part of IEC 61326 specifies requirements for immunity and emissions regarding electro­magnetic compatibility (EMC) for electrical equipment, operating from a supply or battery of less than 1 000 V AC or 1 500 V DC or from the circuit being measured. Equipment intended for professional, industrial-process, industrial-manufacturing and educational use is covered by this part. It includes equipment and computing devices for

measurement and test;

< >

< > use;

accessories intended for use with the above (such as sample handling equipment),

intended to be used in industrial and non-industrial locations.

Computing devices and assemblies and similar equipment within the scope of Information Technology Equipment (ITE) and complying with applicable ITE EMC standards may be used in systems within the scope of this part of IEC 61326 without additional testing, if they are suitable for the intended electromagnetic environment.

It is generally considered that this product family standard takes precedence over the corresponding generic EMC standards.

The following equipment is covered by this standard.

a)  Electrical measurement and test equipment

     This is equipment which, by electrical means, measures, indicates or records one or more electrical or non-electrical quantities, also non-measuring equipment such as signal generators, measurement standards, power supplies and transducers.

b)  Electrical control equipment

     This is equipment which controls one or more output quantities to specific values, with each value determined by manual settings, by local or remote programming, or by one or more input variables. This includes Industrial Process Measurement and Control (IPMC) equipment, which consists of devices such as:

–   process controllers and regulators;

–   programmable controllers;

–   power supply units for equipment and systems (centralized or dedicated);

–   analogue/digital indicators and recorders;

–   process instrumentation;

–   transducers, positioners, intelligent actuators, etc.

 

c)  Electrical laboratory equipment, including In Vitro Diagnostic (IVD) equipment

     This is equipment used to prepare or analyse materials, or measure, indicate or monitor physical quantities. This equipment might also be used in areas other than laboratories.

d)  Equipment a), b) or c) as above when being equipped with components having radio functionality, for example for wireless communication.

Equipment within the scope of this standard might be operated in different electromagnetic environments; depending on the electromagnetic environment different emission and immunity test requirements are applicable.

This standard considers three types of electromagnetic environments:

basic electromagnetic environment;

industrial electromagnetic environment;

controlled electromagnetic environment.

Corresponding immunity test requirements are described in Clause 6.

In terms of emission requirements, equipment shall be classified in Class A or Class B equipment, as per the requirements and procedure of CISPR 11. The corresponding emission requirements are described in Clause 7.

The specified emission and immunity requirements aim at achieving electromagnetic compatibility between equipment covered in this standard and other equipment that might operate at locations with electromagnetic environments considered in this standard. Guidance for an assessment concerning the risk for achieving EMC is given in Annex B.

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].
