This International standard specifies marking locations and a coding system of marking for ferrite cores. An alphanumerical marking printed or attached to cores reduces the risk of incorrect assembly mixing of materials and/or mixing of gapped cores on an assembly line. The markings of inductance factor AL value or of the gap length are especially important to avoid this kind of problem and the coding system is specified in this standard.

The scope of this standard is to describe the concepts, techniques and limitations of the Finite-Element method and to specify models and procedures for validation and uncertainty assessment for the Finite-Element Method when used for determining the spatial-peak specific absorption rate (psSAR) in phantoms or anatomical models. It recommends and provides guidance on the modelling of wireless devices and provides benchmark data for the simulation the SAR in such phantoms or models.

This standard does not recommend specific SAR limits since these are found elsewhere, e.g., in IEEE C95.1 [1] or in the guidelines published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) [2].

NOTE Cubical averaging volumes are applied in all current experimental standards for the assessment of psSAR and recommended by [1], [2] and [3]. Other averaging volumes have been proposed, e.g., in [2], and may be included in future revisions of this standard.

This part of IEC 62282 defines the evaluation methods of typical performances for electric energy storage systems using hydrogen. This is applicable to the systems which use electrochemical reaction devices for both power charge and discharge.

The conceptual configurations of the electric energy storage systems using hydrogen are shown in Figure 1 and Figure 2. Figure 1 shows the system independently equipped with an electrolyzer module and a fuel cell module. Figure 2 shows the system equipped with a reversible cell module. There are an electrolyzer, a hydrogen storage and a fuel cell, or a reversible cell and a hydrogen storage as indispensable components, and a battery, an oxygen storage, a heat management system, a water management system and an overall management system as optional components. The performance measurement is executed in the area surrounded by the outside thick solid line square (system boundary).

Note: In the context of this international standard, the term “reversible” does not refer to the thermodynamic meaning of an ideal process. It is common practice in the fuel cell community to call the operation mode of a cell that alternates between fuel cell mode and electrolysis mode “reversible”.

A typical targeting application of the electric energy storage systems using hydrogen is in the class of energy intensive electric energy storage. The systems are recognized as critically useful for the relatively long-term power storage operation, such as efficient storage and supply of the renewable power derived electric energy and grid stabilization.

This international standard is to be used for data exchanges in commercial transactions between the system suppliers and customers. Users of this international standard may selectively execute test items suitable for their purposes from those described in this international standard.

This part of IEC 61076-2 describes the bayonet coupling interface of circular connectors that are typically used for industrial process measurement and control. These connectors consist of fixed and free connectors either rewireable or non-rewireable, with bayonet-coupling. These connectors may have glass to metal seal inserts. They have male or female contacts and are deemed be intermateable with corresponding free connectors produced according to this International Standard. Male connectors have round contacts Ø 0,6 mm, Ø 0,76 mm,
Ø 0,8 mm and Ø 1,0 mm.

Differing coding’s shall prevent the mating of these individually coded fixed connectors (and consequently of individually coded free connectors deemed to bayonet couple with them) to other interfaces and cross-mating between the different coding’s. However, the styles and interface dimensions, except for the coupling mechanism, shall be as given in of subclause 4.3 of IEC 61076-2- 101:2012 and subclause 4.3.1 of IEC 61076-2-109:2014.

The male type B12 circular connectors shall be interoperable with the female type B12 connector of the same coding and ways. The female type B12 connectors shall be interoperable with the male type B12 and M12 (threaded screw coupling) connector of the same coding and ways.

NOTE – B12 relates to a bayonet coupling with tube dimensions compatible with a M12 thread. M12 is the dimension of the thread of the screw-coupling mechanism of circular connectors covered by IEC 61076-2-101 and IEC 61076-2-109, which provide the mating interface (connector insert level) to these connectors with bayonet coupling.

This part of ISO/IEC 14543 specifies a wireless protocol for low-powered devices such as energy harvested devices in a home environment. This wireless protocol is specifically designed to keep the energy consumption of such sensors and switches extremely low.

The design is characterised by

keeping the communications very short, infrequent and mostly unidirectional, and

using communication frequencies that provide a good range even at low transmit power and avoid collisions from disturbers.

This allows the use of small and low cost energy harvesters that can compete with similar batteries-powered devices. The messages sent by energy harvested devices are received and processed mainly by line-powered devices such as relay switch actuators, repeaters or gateways. Together these form part of a home automation system, which, when conforming to the ISO/IEC 14543 series of standards, is defined as a home electronic system.

This part of ISO/IEC 14543 specifies OSI Layers 1 to 3 of the Amplitude Modulated Wireless Short-Packet (AMWSP) protocols.

The AMWSP protocol system consists of two and optionally three types of components that are specified in this standard. These are the transmitter, the receiver and optionally the repeater. Repeaters are needed when the transmitter and the receiver are located in such a way that no good direct communication between them can be established.

Protection against malicious attacks is handled in the upper layers and thus not treated in this standard.

This part of 62047 specifies the test method of electrical characteristics under bending deformation for flexible and foldable electro-mechanical devices, where foldable device still functions while the device is even folded in half.  These devices include passive micro components and (or) active micro components on the flexible film or imbedded in the flexible film. The desired in-plane dimension of the device for the test method ranges typically from 1mm to 300mm and the thickness ranges from 10mm to 1mm, but not limited to. The test method is so designed as to bent devices in a quasi-static manner monotonically up to the maximum possible curvature, i.e. until the device is completely folded in half, so that the entire degradation behaviour of electric property under bending deformation is obtained. This part is essential to estimate the safety margin under certain bending deformation and indispensable for reliable design of the product employing these devices.[Office1]
