This part of IEC 60071 constitutes application guidelines and deals with the selection of insulation levels of equipment or installations for three-phase a.c. systems. Its aim is to give guidance for the determination of the rated withstand voltages for ranges I and II of IEC 60071-1 and to justify the association of these rated values with the standardized highest voltages for equipment.

This association is for insulation co-ordination purposes only. The requirements for human safety are not covered by this document.

This document covers three-phase a.c. systems with nominal voltages above 1 kV. The values derived or proposed herein are generally applicable only to such systems. However, the concepts presented are also valid for two-phase or single-phase systems.

This document covers phase-to-earth, phase-to-phase and longitudinal insulation.

This document is not intended to deal with routine tests. These are to be specified by the relevant product committees.

The content of this document strictly follows the flow chart of the insulation co-ordination process presented in Figure 1 of IEC 60071-1:2019. Clauses 5 to 8 correspond to the squares in this flow chart and give detailed information on the concepts governing the insulation co-ordination process which leads to the establishment of the required withstand levels.

This document emphasizes the necessity of considering, at the very beginning, all origins, all classes and all types of voltage stresses in service irrespective of the range of highest voltage for equipment. Only at the end of the process, when the selection of the standard withstand voltages takes place, does the principle of covering a particular service voltage stress by a standard withstand voltage apply. Also, at this final step, this document refers to the correlation made in IEC 60071-1 between the standard insulation levels and the highest voltage for equipment.

The annexes contain examples and detailed information which explain or support the concepts described in the main text, and the basic analytical techniques used.

This International Standard applies to in-cable control and protection devices (IC-CPDs) for mode 2 charging of electric road vehicles, hereafter referred to as IC-CPD including control and safety functions.

This standard applies to portable devices performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value.

The IC-CPD according to this standard

has a control pilot function controller in accordance with IEC 61851-1:2017, Annex A;

checks supply conditions and prevents charging in case of supply faults under specified conditions;

may have a switched protective conductor.

Residual currents with frequencies different from the rated frequency, DC residual currents and specific environmental situation are considered.

This standard is applicable to IC-CPDs performing the safety and control functions as required in IEC 61851-1 for mode 2 charging of electric vehicles.

This standard is applicable to IC-CPDs for single-phase circuits not exceeding 250 V or multi-phase circuits not exceeding 480 V, their maximum rated current being 32 A.

This standard is applicable to IC-CPDs to be used in AC circuits only, with preferred values of rated frequency 50 Hz, 60 Hz or 50/60 Hz. IC-CPDs according to this standard are not intended to be used to supply electric energy towards the connected grid.

This standard is applicable to IC-CPDs having a rated residual operating current not exceeding 30 mA and are intended to provide additional protection for the circuit downstream of the IC-CPD in situations where it cannot be guaranteed that the installation is equipped with an RCD with I∆n  £ 30 mA.

The IC-CPD consists of:

a plug for connection to a socket-outlet in the fixed installation;

one or more subassemblies containing the control and protection features;

a cable between the plug and the subassemblies (optional);

a cable between the subassemblies and the vehicle connector (optional);

a vehicle connector for connection to the electric vehicle.

For plugs for household and similar use the respective requirements of the national standard and specific requirements defined by the national committee of the country where the product is placed on the market apply. If no national requirements exist, IEC 60884-1 applies. For industrial plugs IEC 60309-2 applies. For specific applications and areas non interchangeable industrial plugs may be used. In this case IEC 60309-1 applies

Plugs, connectors and cables which are part of the IC-CPD are not tested according to this standard. These parts are tested separately according to their specific product standard.

The switching contacts of the IC-CPD are not intended to provide an isolation function, as isolation can be ensured by disconnecting the plug.

The IC-CPD is not considered to be a protective device for use in fixed installations.

This part of IEC 62471 specifies an assessment of the photobiological safety of electrical light sources and luminaires in normal use. The assessment is applied for electrical light sources and luminaires that emit radiation predominantly in the visible spectral range (380 nm to 780 nm) and are used to illuminate spaces or objects or used for signalling.

Electrical light sources and luminaires designed for emitting radiation in the visible range can also emit radiation in the ultraviolet (UV) and infrared (IR) regions depending on the technology applied. The photobiological safety assessment in this document, therefore, includes the blue light-, thermal-, UV-, UV-A-, IR- and skin thermal- hazards (includes optical radiation over the wavelength range 200 nm to 3 000 nm).

Electrical light sources and luminaires that are designed to predominantly emit radiation outside the visible spectral range (380 nm to 780 nm) (e.g. UV sterilizers or industrial heaters) are not within the scope of this document.

Electrical light sources for illumination are considered to emit continuous light (pulse width modulation (PWM) are included), therefore emission levels of continuous light (continuous wave (CW)) are applied.

When there is no limitation on the presence of people, this document can be applied to electrical light sources and luminaires which emit visible light, but the main purpose is not illumination or signalling (e.g. horticulture).

This document also applies to laser products when the conditions of IEC 60825-1:2014, 4.4 are met and they are used for illumination or signalling.

Note:       See IEC 60825-1:2014 for other requirements of laser products.

This document is intended to be referenced by TC 34 product standards for the assessment of applicable photobiological safety aspects. Additional details for the photobiological safety assessment and data presentation are specified in the product standards.

This part of IEC 62351 specifies how to provide confidentiality, integrity protection, and message level authentication for protocols that make use of TCP/IP as a message transport layer and utilize Transport Layer Security when cyber-security is required. This may relate to SCADA and telecontrol protocols, but also to additional protocols if they meet the requirements in this standard.

IEC 62351-3 specifies how to secure TCP/IP-based protocols through constraints on the specification of the messages, procedures, and algorithms of Transport Layer Security (TLS) (TLSv1.2 defined in RFC 5246, TLSv1.3 defined in RFC 8446). In the specific sections, there will be subclauses to note the differences and commonalities in the application depending on the target TLS version. The use and specification of intervening external security devices (e.g., “bump-in-the-wire”) are considered out-of-scope.

In contrast to former versions of this standard, this edition is self-contained in terms of completely defining a profile of TLS. Hence, it can be applied directly, without the need to specify further TLS parameters. Therefore, this part can be directly utilized from a referencing standard and may be combined with further security measures on other layers. Providing the profiling of TLS without the need for further specifying TLS parameters allows to declare conformity to the described functionality without the need to involve further IEC 62351 documents.

This part is intended to be referenced as a normative part of other IEC standards that have the need for providing security for their TCP/IP-based protocol exchanges under similar boundary conditions. However, it is up to the individual protocol security initiatives to decide if this standard is to be referenced.

The document also defines security events for specific conditions, which support the error handling, security audit trails, intrusion detection and conformance testing. The actions of the organisation in response to events to an error condition described in this document are beyond the scope of this document and are expected to be defined by the organizations security policy.

This part of IEC 62351 reflects the security requirements of the IEC power systems management protocols. Should other standards bring forward new requirements, this standard may need to be revised.
