IEC 62714-1:2018 is a solution for data exchange focusing on the domain of automation engineering. The data exchange format defined in the IEC 62714 series (Automation Markup Language, AML) is an XML schema based data format and has been developed in order to support the data exchange in a heterogeneous engineering tools landscape. The goal of AML is to interconnect engineering tools in their different disciplines, e.g. mechanical plant engineering, electrical design, process engineering, process control engineering, HMI development, PLC programming, robot programming, etc. This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:a) use of CAEX 3.0 according to IEC 62424:2016b) improved modelling of references to documents outside of the scope of the present standard,c) modelling of references between CAEX attributes and items in external documents,d) revised role libraries,e) modified Port concept,f) modelling of multilingual expressions,g) modelling of structured attribute lists or array,h) a new AML container format,i) a new standard AML attribute library

IEC 61784-3:2021 explains some common principles that can be used in the transmission of safety-relevant messages among participants within a distributed network which use fieldbus technology in accordance with the requirements of IEC 61508 (all parts) for functional safety. These principles are based on the black channel approach. They can be used in various industrial applications such as process control, manufacturing automation and machinery.

IEC 62443-3-2:2020 establishes requirements for:• defining a system under consideration (SUC) for an industrial automation and control system (IACS). • partitioning the SUC into zones and conduits. • assessing risk for each zone and conduit. • establishing the target security level (SL-T) for each zone and conduit; and• documenting the security requirements.

IEC TR 63074:2019 gives guidance on the use of IEC 62443 (all parts) related to those aspects of security threats and vulnerabilities that could influence functional safety implemented and realized by safety-related control systems (SCS) and could lead to the loss of the ability to maintain safe operation of a machine.Considered security aspects of the machine with potential relation to SCS are:– vulnerabilities of the SCS either directly or indirectly through the other parts of the machine which can be exploited by security threats that can result in security attacks (security breach). – influence on the safety characteristics and ability of the SCS to properly perform its function(s). – typical use case definition and application of a corresponding threat model.

This part of lEC 60320 sets the general requirements for appliance couplers for two poles andtwo poles with earth contact and for the connection of electrical devices for household andsimilar onto the mains supply.This document is also valid for appliance inlets/appliance outlets integrated or incorporated inappliances.The rated voltage does not exceed 250 V (AC) and the rated current does not exceed 16 A.Appliance couplers complying with this document are suitable for normal use at ambienttemperatures not normally exceeding +40 °C, but their average over a period of 24 h does notexceed +35 °C, with a lower limit of the ambient air temperature of −5 °C.Annex E provides test requirements for derating the operating current of an accessory whenused in ambient temperatures above +35 °C up to and including +90 °C.Appliance couplers are not suitable for:– use in place of plug and socket-outlet systems according to IEC 60884-1. – use in place of devices for connecting luminaires (DCLs) according to IEC 61995 orluminaire supporting couplers (LSCs). – use in place of installation couplers according to IEC 61535.

IEC 60664-1:2020 deals with insulation coordination for equipment having a rated voltage up to AC 1 000 V or DC 1 500 V connected to low-voltage supply systems. This document applies to frequencies up to 30 kHz. It applies to equipment for use up to 2 000 m above sea level and provides guidance for use at higher altitudes. It provides requirements for technical committees to determine clearances, creepage distances and criteria for solid insulation. It includes methods of electrical testing with respect to insulation coordination. The minimum clearances specified in this document do not apply where ionized gases are present. Special requirements for such situations can be specified at the discretion of the relevant technical committee. This document does not deal with distances:– through liquid insulation. – through gases other than air. – through compressed air.This edition includes the following significant technical changes with respect to the previous edition:update of the Scope, Clauses 2 and 3,addition of 1 500 V DC into tables,new structure for Clauses 4 and 5,addition of Annex G with a flowchart for clearances,addition of Annex H with a flowchart for creepage distances,update of distances altitude correction in a new Table F.10.

IEC 60068-2-1:2007 Deals with cold tests applicable to both non heat-dissipating and heat-dissipating specimens. For non heat-dissipating specimens, Tests Ab and Ad do not deviate essentially from earlier issues. Test Ae has been added primarily for testing equipment that requires being operational throughout the test, including the conditioning periods. The object of the cold test is limited to the determination of the ability of components, equipment or other articles to be used, transported or stored at low temperature. Cold tests cover by this standard do not enable the ability of specimens to withstand or operate during the temperature variations to be assessed. In this case, it would be necessary to use IEC 60068-2-14. The cold tests are subdivided as follows:- Cold tests for non heat-dissipating specimens: * with gradual change of temperature, Ab. - Cold test for heat-dissipating specimens: * with gradual change of temperature, Ad,* with gradual change of temperature, specimen powered throughout, Ae.The procedures given in this standard are normally intended for specimens that achieve temperature stability during the performance of the test procedure. Temperature chamber(s) are constructed and verified in accordance with specifications IEC 60068-3-5 and IEC 60068-3-7. Further guidance for dry heat and cold tests can be found in IEC 60068-3-1 and general guidance in IEC 60068-1. This sixth edition deals with cold tests applicable both to non heat-dissipating and heat-dissipating specimens. For non heat-dissipating specimens, Tests Ab and Ad do not deviate essentially from earlier issues. Test Ae has been added primary for testing equipment that requires being operational throughout the test including the conditioning periods.

ISO/IEC 29182-2:2013 is intended to facilitate the development of International Standards in sensor networks. It presents terms and definitions for selected concepts relevant to the field of sensor networks. It establishes a general description of concepts in this field and identifies the relationships among those concepts. It may also be used as guidance for development of other parts of ISO/IEC 29182 and any other sensor network related standard.
