Scope:
This part of IEC 60947 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.

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:

Distributed energy resources connection with the grid - Part 101: Gravity storage connection to the grid
Scope:
IEC TR 62786-101:2026 provides the principles and general technical characteristics of gravity energy storage systems (GESS) connected to the distribution network. It provides a reference for the planning, design, grid connection and operation of GESS. It includes an introduction to GESS, grid-connection methods, grid-connected characteristics, grid-connected operation and grid-connected testing and so on.
GESS can use liquid or solid mediums for storing or releasing energy. For example, traditional pumped storage utilizes liquid water to achieve energy storing or releasing. This document only focuses on the solid GESS, which utilize solid materials (such as concrete, slag, construction waste, etc.) for energy storage. Generally, GESS can be classified as vertical GESS and slope GESS. In the GESS, the motor-generators (MG) that are directly connected, or indirectly connected to the low voltage (LV) or medium voltage (MV) distribution network through converters, transfer the energy between the mass blocks and the grid. This document reports the grid-connection method, active power response characteristic, response of active power to frequency, response of reactive power to voltage and test of direct grid connection through synchronous motor-generator (SMG), as a supplement to IEC TS 62786-1:2023.
This document describes the interface arrangement for the connection of GESS to distribution networks with the nominal frequency of 50 Hz or 60 Hz.

Mineral insulating oils - Characterization of paraffinic/naphthenic nature - Low temperature differential scanning calorimetry (DSC) test method
Scope:
Describes a test method for the classification of mineral insulating oils as either paraffinic or naphthenic, by means of low-temperature differential scanning calorimetry (DSC).
For the purpose of this technical report, the typical operating temperature range extends from -100 °C to +100 °C. The temperature range can be extended, depending upon the instrumentation used.
The method is applicable to mineral insulating oils obtained from petroleum crudes. It may be also applied to mineral oils containing pour point depressants, as these additives do not prevent the formation of paraffin crystals but only the growing of such micro-crystals.

Assessment of electrical flexibility services from power network perspective
Scope:
This document aims at standardizing concepts, terms and definitions relating to electrical flexibility as well as methodology to assess electrical flexibility services.
The purpose of this document is to define a standardized characterization of electrical flexible services, so that data collected by transmission system operators or distribution system operators can be used and compared in an interoperable manner.
In addition to the development of relevant use cases, the project will focus on the following normative aspects:
— definition and characterization of the different types of electrical flexibilities depending, in particular, on the flexibility needs and the response time;
— activation or control mode of the flexibility services;
— measurement provisions: e.g. consistency with the data of the electricity smart meters and the metrology requirements and the use of dedicated measurement devices;
— information exchanges between concerned parties;
— verification of delivery of service.

Lamps, light sources and LED packages for road vehicles - Performance requirements
Scope:
This document is applicable to filament lamps, discharge lamps, LED light sources, LED packages and OLED light sources to be used in road vehicles, i.e. in headlamps, fog-lamps, signalling lamps and interior lighting. It is especially applicable to those lamps and light sources which are listed in IEC 60809:2021.
It specifies requirements and test methods for the measurement of performance characteristics such as lamp life, luminous flux maintenance, torsion strength, glass bulb strength and resistance to vibration and shock. Moreover, information on temperature limits, maximum lamp outlines and maximum tolerable voltage surges is given as guidance for lighting and electrical equipment design.
For some of the requirements given in this document, reference is made to data given in tables.
For lamps not listed in such tables, the relevant data are supplied by the lamp manufacturer or responsible vendor.
The performance requirements are additional to the basic requirements specified in IEC 60809:2021. They are, however, not intended to be used by authorities for legal type-approval purposes.
NOTE 1 In the various vocabularies and standards, different terms are used for "incandescent lamp" (IEC 60050-845, 845-07-04) and "discharge lamp" (IEC 60050-845, 845-07-17). In this document, "filament lamp" and "discharge lamp" are used. However, where only "lamp" is written both types are meant, unless the context clearly shows that it applies to one type only.
NOTE 2 This document does not apply to luminaires.
NOTE 3 In this document, the term LED light source is used, in other standards the term LED lamps can be used to describe similar products.
