An object identifier (OID) is an identifier to name an object in a hierarchically assigned namespace. In the Internet of things (IoT), thousands of IoT resources will be intricately provided as fusion types of various services. For the thousands of IoT resources, object identifiers (OIDs) can provide a resolution framework with unlimited scalability. On the other hand, IoT resources need to secure their data, so the distributed ledger technology (DLT) can guarantee its integrity. In consequence, the convergence of DLT and OIDs provides a good solution for identifying secured data of IoT resources. Recommendation ITU-T Y.4476 therefore specifies a resolution framework for the transactions of a distributed ledger assigned to IoT resources. Recommendation ITU-T Y.4476 also describes the concepts, functional requirements, architecture and procedures of an OID-based resolution framework by using DLT.

This Recommendation defines the reference framework and high-level requirements of smart city platforms. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published. The reference to a document within this Recommendation does not give it, as a stand-alone document, the status of a Recommendation.

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

A set of ontologies with different abstraction levels that contain concepts, definitions, axioms, and use cases that assist in the development of ethically driven methodologies for the design of robots and automation systems is established by this standard.

A map data representation of environments of a mobile robot performing a navigation task is specified in this standard. It provides data models and data formats for two-dimensional (2D) metric and topological maps.

This standard extends IEEE Std 1872-2015, IEEE Standard for Ontologies for Robotics and Automation, to represent additional domain-specific concepts, definitions, and axioms commonly used in Autonomous Robotics (AuR). This standard is general and can be used in many ways--for example, to specify the domain knowledge needed to unambiguously describe the design patterns of AuR systems; to represent AuR system architectures in a unified way; or as a guideline to build autonomous systems consisting of robots operating in various environments.

A core ontology that specifies the main, most general concepts, relations, and axioms of robotics and automation (R&A) is defined in this standard, which is intended as a reference for knowledge representation and reasoning in robots, as well as a formal reference vocabulary for communicating knowledge about R&A between robots and humans. This standard is composed of a core ontology about R&A, called CORA, together with other ontologies that give support to CORA.

ISO/TS 15066:2016 specifies safety requirements for collaborative industrial robot systems and the work environment, and supplements the requirements and guidance on collaborative industrial robot operation given in ISO 10218‑1 and ISO 10218‑2.ISO/TS 15066:2016 applies to industrial robot systems as described in ISO 10218‑1 and ISO 10218‑2. It does not apply to non-industrial robots, although the safety principles presented can be useful to other areas of robotics.NOTE This Technical Specification does not apply to collaborative applications designed prior to its publication

Environmental testing - Part 2-27: Tests - Test Ea and guidance: Shock

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.

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.
