The present document defines the stage 3 specifications of the Supplementary Service Dynamic Group Number Assignment (SS-DGNA) for the Terrestrial Trunked Radio (TETRA). The SS-DGNA enables a user to dynamically define group identities and group related parameters to the TETRA system and to the subscribers in the system. These definitions are used to enable group call invocations to dynamically defined groups. The SS-DGNA specification defines the creation, modification, deletion and interrogation of group definitions in the Switching and Management Infrastructure (SwMI), in the Mobile Station (MS). The present document does not include the specification for access priority used for random access in uplink and call priority used by SwMI for resource allocation in a group call. Access priority and call priority can be specified and applied for groups using Supplementary Services Access Priority (SS-AP), Priority Call (SS-PC) and Pre-emptive Priority Call (SS-PPC). Thus, the definition procedure of these priorities is outside the scope of the present document. Man Machine Interface (MMI) and charging principles are also outside the scope of the present document. Supplementary service stage 3 specification is preceded by the stage 1 and the stage 2 specifications of the service. Stage 1 describes the functional capabilities from the user's point of view. Stage 2 defines the functional behaviour in terms of functional entities and information flows. Stage 3 gives the precise description of the supplementary service from the implementation point of view. It defines the protocols for the service and the encoding rules for the information flows. It defines the processes for the functional entities and their behaviour. The described protocols and their behaviour apply for the SwMI and for the MS and can be applied over the Inter-System Interface (ISI) between TETRA systems.

The present document defines the Terrestrial Trunked Radio (TETRA) system supporting Voice plus Data (V+D). It specifies:
• the interworking of individual calls between TETRA networks;
• the supplementary services interaction with individual calls between TETRA networks.
The TETRA V+D interworking - basic operation part defines the interworking between TETRA networks over the corresponding interface: the Inter-System Interface (ISI). It comprises the following sub-parts:
• Transport layer independent General design [2];
• General Design, PSS1 over E.1 [i.10];
• General Design, SIP/IP [i.11];
• Transport layer independent Additional Network Feature - ISI Individual Call (ANF-ISIIC) (the present document);
• Transport layer independent Additional Network Feature - ISI Group Call (ANF-ISIGC) [5];
• Transport layer independent Additional Network Feature - ISI Short Data service (ANF-ISISDS) [i.8];
• Transport layer independent Additional Network Feature - ISI Mobility Management (ANF-ISIMM) [6];

The present document is the ANF-ISIIC sub-part. Like all other Additional Network Feature (ANF) specifications, those of ANF-ISIIC are produced in three stages, according to the method described in Recommendation ITU-T I.130 [i.4]. The present document contains the stage 1 and 2 descriptions of ANF-ISIIC, and stage 3 description. The stage 1 description specifies the ANF as seen by its users, which are essentially the individual call control entities in both TETRA networks. The stage 2 description identifies the functional entities involved in the ANF and the information flows between them. And the stage 3 description of ANF-ISIIC specifies its protocol.

Consequently, it comprises two steps: the specifications of all protocols at the various reference points involved in any of the service procedures (notably the service operation) are the first step of the stage 3 description, and the specifications of the functions of the corresponding network entities are its second step. NOTE 2: The SDL diagrams have not been provided since they can be derived from the specification of the functional entity actions in the stage 2 description. The present document applies to TETRA networks which support inter-TETRA individual calls. More specifically, it applies to their Circuit Mode Control Entities (CMCE), as defined in clause 14.2 of ETSI EN 300 392-2 [1], and to their ANF-ISIIC entities defined in the stage 2 description. The relation between the ANF-ISIIC and the transport layer protocol is described in the General Design documents [2], [i.10] and [i.11].

This part of IEC 62321 describes the screening analysis of substances, specifically lead (Pb), mercury (Hg), cadmium (Cd), total chromium (Cr), total bromine (Br), total phosphorus (P), assuming the source of P is related to TCEP (CAS 115-96-8), Trixylyl‑phosphate (CAS 25155-23-1), total chlorine (Cl), assuming the source of Cl is related to SCCP (CAS 85535-84-8), TCEP (CAS 115-96-8) , TBTC (CAS 1461-22-9), total tin (Sn), assuming the source of Sn is related to restricted organo‑tin compounds, total antimony (Sb), assuming the source of Sb is related to Pyrochlore, and antimony lead yellow (CAS 8012-00-8) in uniform materials found in electrotechnical products, using the analytical technique of X‑ray fluorescence (XRF) spectrometry.
The same methodology can also be used for screening of substances discussed as critical raw materials in various countries (for example currently discussed in the EU: antimony (Sb), baryte, bismuth (Bi), cobalt (Co), fluorspar, gallium (Ga), germanium (Ge), hafnium (Hf), indium (In), magnesium (Mg), niobium (Nb), phosphorus (P), scandium (Sc), tantalum (Ta), tungsten (W), vanadium (V), platinum group metals, heavy rare earth elements, light rare earth elements).
NOTE From EU information on critical raw materials [1]1 raw materials are crucial to Europe's economy. They form a strong industrial base, producing a broad range of goods and applications used in everyday life and modern technologies. Reliable and unhindered access to certain raw materials is a growing concern within the EU and across the globe. To address this challenge, the European Commission has created a list of critical raw materials (CRMs) for the EU, which is subject to a regular review and update. CRMs combine raw materials of high importance to the EU economy and of high risk associated with their supply.
The method is applicable to plastics, metals and ceramic materials. The test method can be applied to raw materials, individual materials taken from products and "homogenized" mixtures of more than one material. Screening of a sample is performed using any type of XRF spectrometer, provided it has the performance characteristics specified in this test method. Not all types of XRF spectrometers are suitable for all sizes and shapes of sample. The appropriate spectrometer design will be selected with care for the task concerned.
The performance of this test method has been tested for the following substances in various media and within the concentration ranges as specified in Table 1 to Table 5. During an IIS (international interlaboratory study) the feasibility of the test method to use for the added elements was tested. The results are listed in Table 6 to Table 10.
These substances in similar media outside of the specified concentration ranges can be analysed according to this test method; however, the performance has not been established for this document.
WARNING – Persons using this International Standard should be familiar with normal laboratory practice. This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions.
This document is a basic environment horizontal publication focusing on test methods and is primarily intended for use by committees in the preparation of publications within the area of environment in accordance with the principles laid down in IEC Guide 123. Wherever applicable, it is the responsibility of committees to make use of environment basic publications in the preparation of their environment group and product publications. Committees can apply this document directly to products when they do not develop a product publication in the area of environment.

This fifth edition cancels and replaces the fourth edition published in 1999, Amendment 1:2005 and Amendment 2:2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
addition of requirements and test for non-solid pins;
additional rating IPX9;
additional marking to indicate neutral terminal and/or earthing terminal.
This document is to be read in conjunction with IEC 60309-1:2021.

IEC TS 61641:2026 identifies methods used to verify the ability of the assembly:
– to limit the risk of injury to personnel during an internal arc-fault;
– to limit the damage to an acceptable level as a result of an internal arc-fault;
– to improve the power availability following an internal arc-fault.
This document takes into consideration:
– the effects of the internal overpressure acting on covers, doors, etc.;
– the thermal effects of the internal arc-fault or its roots on the enclosures and of ejected hot gases and glowing particles.
– the correct function of the IAMS within the assembly;
– the prevention of unintended operation of the IAMS within the assembly, for example caused by switching arcs;
– the functioning behaviour of the IAMS immediately after the assembly is energized.
This document describes different methods to assess the performance of an assembly or zones of an assembly in respect of arcing in air due to an internal failure:
– with "passive" arc-fault protection (provided by mechanical construction, e.g. suitable door locks, hinges, pressure relief devices, barriers);
NOTE 1 This approach corresponds to the method according to IEC TR 61641:2014.
– with "active" arc-fault protection (with the integration of IAMS);
NOTE 2 This approach corresponds to the method according to IEC TS 63107:2020.
– with the use of an arc ignition protected zone (to make the ignition of an arc-fault an extremely remote possibility).
NOTE 3 This approach corresponds to the method according to IEC TR 61641:2014.
IAMS consist of internal arc-fault control devices (IACD), e.g. optical-based IACD's in accordance with IEC 60947-9-2 and internal arc-fault reduction devices (IARD), e.g. arc quenching devices (AQDs) in accordance with IEC 60947-9-1 and short-circuit protection devices SCPD's in accordance with IEC 60947-2 (see Figure EE.1). IAMS can be provided by a combined-type device according to IEC 60947-9-2.
IEC 60364-4-42:2024 (Clause 427) provides guidance on the need for internal arc-fault protection.
This document does not supersede any individual product standard. Individual devices are required to comply with their relevant standard.
This document does not apply to integration of arc fault detection devices (AFDD) according to IEC 62606.
Informative Annex AA gives guidance for the user (see IEC 61439-1:2020, 3.11) on internal arc-fault mitigation.
Informative Annex BB gives guidance for the user (see IEC 61439-1:2020, 3.11) of assemblies with "active" arc-fault protection (with the integration of IAMS).
Informative Annex CC gives guidance for the original manufacturer of an assembly when incorporating an integrated IAMS.
This document does not consider other effects which can constitute a risk, such as emission of toxic gases, loud noises and/or intense light. Furthermore, this document does not consider conditions during maintenance work and the personal protective equipment used.
This edition cancels and replaces IEC TR 61641:2014 and IEC TS 63107:2020. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Introduction of the term "arcing class zone", using the term "arcing classes" from the previous document IEC TR 61641:2014.
b) Structured using of the terms "zone" and "area". "Area" is used to describe the place of installation and the accessibility of the assembly (macro-environment). "Zone" is used in this document to describe a defined space within the assembly (micro-environment).
c) Assembly protection is classified into two levels.

IEC 60947-5-3:2026 provides additional requirements to those given in IEC 60947-5-2 and IEC 60947-5-1:2024, Annex D (reed contact magnetic switches). It addresses the fault performance aspects of proximity devices with a defined behaviour under fault conditions (PDDB). It does not address any other characteristics that can be required for specific applications.
This document does not apply to protective equipment to directly detect the presence of persons, that are covered by the IEC 61496 series or IEC TS 62998 series.
NOTE 1 A PDDB device can be used to detect indirectly the presence of a person, for example by detecting the position of a platform on which the operator stands (example, garbage trucks).
This document does not specify requirements for the analogue output of PDDB, if any.
This document does not deal with any specific requirements on acoustic noise as the noise emission of proximity devices is not considered to be a relevant hazard.
A PDDB product is intended to be used as sensing subsystem of a safety related control system according to IEC 62061 or ISO 13849-1. Depending on construction principles and complexity, this document is based on product development of the IEC 61508 series to meet the product specific requirements of one or more of the following:
– IEC 61508 series;
– IEC 62061;
– ISO 13849 series.
NOTE 2 The Functional safety device type classification regarding functional safety correlates with IEC 62683-2-3.
This document includes requirements for PDDB when designed for use as part of an interlocking device according to ISO 14119.
This document does not consider aspects of:

g) The operating modes target present (4.12.2) and target absent (4.12.3) are introduced.
h) The ‘switching distance’ replaces the terms ‘release’ and ‘operating’. The behaviour of the PDDB is described according to the operating mode (4.12).
i) The context and verification of the switching distances are considered according to ISO/IEC Guide 98-3:2008 (GUM) and IEC TR 63649 (see 8.2.1.3 and 9.4.2).
j) Requirements for electrical equipment class III are refined.
k) The risk time is replaced with the safety response time (3.1.11).
l) Annex A gives a new example of safety related control system.
m) The test sequences (see 9.3.1) are updated for the specific behaviour of a PDDB.

This document specifies the procedure for screening soils for selected elements using handheld or portable equipment for energy dispersive X-ray fluorescence spectrometry (ED-XRF). It covers the application of this screening method to obtain qualitative or semi-quantitative data to assist decisions on a sampling strategy for detailed assessment of soil quality employing laboratory analytical chemical methods.
NOTE 1        Screening methods generally provide qualitative or semi-quantitative concentration values that are indicative of concentration values, although occasionally they can give quantitative results under specific or limited conditions.
NOTE 2        The greater the effort applied to the pretreatment of soil samples, the better the analytical results that can be expected (see e.g. Reference [19]).
This document does not explicitly specify elements for which it is applicable, since the applicability depends on the performance of the apparatus and the objective of the screening. The elements which can be determined are limited by the performance of the instrument used, the concentrations of particular elements present in the soil, and the requirements of the investigation in terms of the minimum concentrations of concern (e.g. guideline value).
NOTE 3        The XRF measurements of As, Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, Sb, Sn, V and Zn were validated as described in Annex A.
NOTE 4        Annex B provides examples of when screening with a handheld ED-XRF spectrometer and a portable ED-XRF spectrometer can be useful.
This document does not provide guidance on how to use the equipment to provide quantitative data for use in detailed site assessments. This document does not cover how the results of multiple determinations are synthesized to address the objectives of an ED-XRF determination.
