This International Standard applies to two up to five wire installation couplers including earth, if provided, with a rated voltage up to and including 500 V AC or DC and a rated connecting capacity up to and including 10 mm² for permanent connection in electrical installations. Installation couplers with additional contacts for voltages other than mains voltages are outside the scope of this standard.

NOTE 1   AC and DC installation couplers according to this standard may be used, for example, in prefabricated buildings, commercial show rooms, installation cavities, such as suspended floors and ceilings, in partition walls and in any similar applications, or cable tray systems, cable ladder systems, cable ducting systems and cable trunking systems or in furniture complying with IEC 60364-7-713.

NOTE 2 This standard may be used as a guide for installation couplers with additional contacts for voltages other than mains voltages.

NOTE 3 In the UK, where installation couplers have more than 5 wires, they shall meet the requirements of IEC 61535 as though they were included in the scope and shall be tested in such a way that all of the mains voltage pins are subjected to the same level of testing.

NOTE 4 In the USA, these installation couplers are not permitted to be used where they will not be visible after installation.

An installation coupler consists of an installation female connector and an installation male connector for permanent connection not intended to be engaged or disengaged under load nor to be engaged or disengaged other than during first installation or during reconfiguration or maintenance of the wiring system in which installation couplers have been installed. This means that installation couplers are only intended for infrequent use.

Installation couplers are not suitable for use in place of socket-outlet systems. Installation couplers are not suitable for use in place of devices for connecting luminaires (DCLs) according to IEC 61995 or luminaire supporting couplers (LSCs).

Installation couplers complying with this document are suitable for use at ambient temperatures not normally exceeding +40 °C, but their average over a period does not exceed +35 °C, with a lower limit of the ambient air temperature of -5 °C, either for indoor or outdoor use.

NOTE 5  Additional tests for use in cold climates are under consideration.

NOTE 6 For other temperatures necessary information may be given in the manufacturer’s installation instructions.

In locations where special conditions prevail, as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special constructions may be required.

NOTE 7 Particular requirements for installation couplers e.g. for. use at higher ambient temperatures, with higher mechanical durability (e.g. metal housings), with higher fire resistance and for use in control circuits (e.g. SELV), are under consideration.

NOTE 8 National rules may have requirements concerning the accessibility of installation couplers.

NOTE 9 Installation couplers are intended to be installed by instructed or skilled persons.

NOTE 10 National rules may specify who is allowed to carry out the connection and disconnection of installation couplers.

NOTE 11 National rules may have requirements concerning installation couplers with metal conduits.

This Part 2 of the ICDD standard adds functionality to the container format specified in Part 1. Part 1 defines a generic container format to store documents using various formats and structure and the ability to provide links between documents or between referable subsets of these documents (documents and datasets are the payload of the container). Building on that foundation, Part 2 of this standard adds the possibility of adding more semantic (meaningful) information to the contents of the container, as well as to the links between pieces of information in the container using Linked Open Data technology.
This standard does not prescribe the structure or format of the documents in the payload.
This standard is suitable for industry sectors such as the built environment, where many different standards are used, where there is a mixture of digital representations of proposed or existing built and natural assets (in open or proprietary formats), requiring the use of legacy systems and the application of different classification systems. This part adds the ability to link, in a semantic and meaningful way, those islands of data represented using different formats and structure. This standard is not meant to replace other standards such as ISO 16739 which is recognized as the standard for describing building objects.

This standard provides two conformance classes. Both conformance classes open the ability to specialize the container for use cases not otherwise handled.

In Conformance Class A, the container format of Part 1 is expanded with an ontology dynamic semantics, providing basic support for creating an information model that captures the required semantics of project, organization or sector standards and agreements. By doing so, it provides building blocks that make it easier to link different sources of information. This is achieved by introducing support for typed entities, typed entity properties and typed relationships between those entities (such as the relationship between an assembly and its parts or between a physical entity and its associated requirements). There is also support for defining provenance, versioning and creating libraries.

In Conformance Class B, the user is offered complete freedom to add user defined ontologies to the container, with the sole condition that it is expressed in RDF/OWL.

The use cases are in line with those of Part 1, but may include numerous extensions. The following list gives some examples:

Make use of asset type libraries describing the required properties per asset type

Link to a specific classification system, e.g. CoClass, Uniclass or OmniClass™

Add the ability for exchanging systems engineering information

Link to product requirement libraries

Add semantic links (i.e. meaningful links) to and between information provided using existing standards like PLCS, IFC and GML

Link to an ontology for Units and Measures, like QUDT

Link to one or more Product Catalogues

Since this standard capitalizes on Linked Open Data technology, the header file, along with any additional RDF/OWL files, forms a suite that may be directly queried by software using standard techniques such as SPARQL.

This document gives a brief overview of each of the dynamic techniques which are described in detail in the following parts of ISO 6145. This document provides basic information to support an informed choice for one or another method for the preparation of calibration gas mixtures. It also describes how these methods can be linked to national measurement standards to establish metrological traceability for the composition of the prepared gas mixtures.

Since all techniques are dynamic and rely on flow rates, this first part of ISO 6145 describes the calibration process by measurement of each individual flow rate generated by the device.

Methods are also provided for assessing the composition of the generated gas mixtures by comparison with an already validated calibration gas mixture.

This document provides general requirements for the use and operation of dynamic methods for gas mixture preparation. It also includes the necessary expressions for calculating the calibration gas composition and its associated uncertainty.

Gas mixtures obtained by these dynamic methods can be used to calibrate or control gas analysers.

The storage of dynamically prepared gas mixtures into bags or cylinders is beyond the scope of this document.

The purpose of this document is to describe a procedure for the determination of the ester content in fatty acid methyl esters (FAME) intended for incorporation into diesel oil. It also allows determining the linolenic acid methyl ester content. It allows verifying that the ester content of FAME is greater than 90 % (m/m) and that the linolenic acid content is between 1 % (m/m) and 15 % (m/m).

This method is suitable for FAME which contains methyl esters between C6 and C24.

NOTE 1       For the purposes of this document, the terms “% (m/m)” and “% (v/v)” are used to represent respectively the mass and volume fractions.

NOTE 2       This method was elaborated for FAME samples from usual raw material. For FAME sample from unidentified raw material, a solution of the test sample is prepared without any internal standard addition, in order to verify the absence of natural nonadecanoic acid methyl ester.

NOTE 3       The distribution off fatty acid methyl esters is given in Annex C.

WARNING — The use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
