IEC TR 62541-2:2020 is available as IEC TR 62541-2:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62541-2:2020 describes the OPC Unified Architecture (OPC UA) security model. It describes the security threats of the physical, hardware, and software environments in which OPC UA is expected to run. It describes how OPC UA relies upon other standards for security. It provides definition of common security terms that are used in this and other parts of the OPC UA specification. It gives an overview of the security features that are specified in other parts of the OPC UA specification. It references services, mappings, and Profiles that are specified normatively in other parts of the OPC UA Specification. It provides suggestions or best practice guidelines on implementing security. Any seeming ambiguity between this part and one of the other normative parts does not remove or reduce the requirement specified in the other normative part.

Technical committeeTypeAcronymIEC 62541-10CommitteePublished year2012Description
IEC 62541-10:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 62541-10:2020 defines the information model associated with Programs in the OPC Unified Architecture. This includes the description of the NodeClasses, standard Properties, Methods and Events and associated behaviour and information for Programs. The complete Address Space model including all NodeClasses and Attributes is specified in IEC 62541-3. The Services such as those used to invoke the Methods used to manage Programs are specified in IEC 62541 4. This third edition cancels and replaces the second edition published in 2015. This edition includes several clarifications and in addition the following significant technical changes with respect to the previous edition:
a) Changed ProgramType to ProgramStateMachineType. This is in line with the NodeSet (and thus implementations). In ProgramDiagnosticDataType: changed the definition of lastInputArguments and lastOutputArguments and added two additional fields for the argument values. Also changed StatusResult into StatusCode. Created new version of the type to ProgramDiagnostic2DataType.
b) Changed Optional modelling rule to OptionalPlaceHolder for Program control Methods. Following the clarification in IEC 62541-3, this now allows subtypes (or instances) to add arguments. -
Technical committeeTypeAcronymIEC 62532CommitteePublished year2011KeywordsDescription
IEC 62532:2011+A1:2016 specifies the safety requirements for fluorescent induction lamps for general lighting purposes. It also specifies the method a manufacturer should use to show compliance with the requirements of this standard on the basis of whole production appraisal in association with his test records on finished products. This method can also be applied for certification purposes. Details of a batch test procedure, which can be used to make limited assessment of batches, are also given in this standard. This consolidated version consists of the first edition (2011) and its amendment 1 (2016). Therefore, no need to order amendment in addition to this publication.

Technical committeeTypeAcronymIEC 62504CommitteePublished year2014KeywordsDescription
IEC 62504:2014+A1:2018 is of assistance in the common understanding of terms and definitions, relevant for general lighting with LED technology. The terms included are those already available in IEC LED standards or used in manufacturers' literature. This standard provides descriptive terms (like "LED light sources") and measurable terms when modified from IEC 60050-845 (like "colour rendering index"). This first edition cancels and replaces the IEC TS 62504 published in 2011. The significant changes with respect to IEC TS 62504 are as follows:
a) Terms from the International Electrotechnical Vocabulary that have not been modified are deleted;
b) Alignment with the CIE has been done;
c) An introduction has been added. This consolidated version consists of the first edition (2014) and its amendment 1 (2018). Therefore, no need to order amendment in addition to this publication.Technology -

IEC 62501:2009+A1:2014+A2:2017 applies to self-commutated converter valves, for use in a three-phase bridge voltage sourced converter (VSC) for high voltage d.c. power transmission or as part of a back-to-back link. It is restricted to electrical type and production tests. This consolidated version consists of the first edition (2009), its amendment 1 (2014) and its amendment 2 (2017). Therefore, no need to order amendment in addition to this publication.

Technical committeeTypeAcronymIEC 62493CommitteePublished year2015KeywordsDescription
IEC 62493:2015 applies to the assessment of lighting equipment related to human exposure to electromagnetic fields. The assessment consists of the induced internal electric field for frequencies from 20 kHz to 10 MHz and the specific absorption rate (SAR) for frequencies from 100 kHz to 300 MHz around lighting equipment. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) identification of lighting product types deemed to comply with the standard without the need for test;
b) deletion of the need for CISPR-15-compliance as a prerequisite for IEC 62493 compliance;
c) inclusion of the consequences of the ICNIPR 2010 guidelines for (up to 100 kHz);
d) adding some guidance to the Van der Hoofden test head method to improve reproducibility of results;
e) inclusion of compliance demonstration method for products having intentional radiators.Technology -

This Final Draft International Standard is an up to 6 weeks' pre-release of the official publication. It is available for sale during its voting period: 2021-02-12 to 2021-03-26. By purchasing this FDIS now, you will automatically receive, in addition, the final publication.
EC 62488-3 applies to power line carrier terminals and networks used to transmit information over power networks including extra high, high and medium voltage (EHV/HV/MV) power lines using both digital and optionally analogue modulation systems in a frequency range between 16 kHz and 1 MHz (see also IEC 62488-1).
In many countries, power line carrier (PLC) channels represent a significant part of the utility-owned telecommunication system. A circuit normally routed via a PLC channel can also be routed via a channel using a different transmission medium such as point to point radio, optical fibre or open wire circuit.
It is therefore important that the input and output interfaces that are used between terminals in the communication system are standardised.
The issues requiring consideration of DPLC and/or APLC devices as parts of a telecommunication network can be found in IEC 62488-1.
The scope of this document also includes the description of I/O interfaces and test set-ups that are necessary to qualify characteristics of DPLC or ADPLC terminal at link level. -
Technical committeeTypeAcronymIEC 62488-1CommitteePublished year2012Description
IEC 62488-1 applies to the planning of analogue and digital power line carrier systems operating over EHV/HV/MV electricity grids. The object of this standard is to establish the planning of the services and performance parameters for the operational requirements to transmit and receive data efficiently over power networks. The transmission media used by the different electricity supply industries will include analogue and digital systems together with more common communication services including national telecommunications authorities, radio links and fibre optic networks and satellite networks. With the developments in communication infrastructures over the last two decades and the ability of devices connected in the electricity communications network to internally and externally communicate, there is a variety of architectures to use in the electricity distribution network to provide efficient seamless communications.
