This part of IEC 60455 gives the requirements for resins for power cable accessories that
conform to this specification and meet established levels of performance. However, the
selection of a material by a user for a specific application will be based on the actual
requirements necessary for adequate performance in that application and not on this
specification alone.
These materials are designed to be used in low and medium voltage cable accessories and as
such, electrical performance is proven as part of the assembly. Examples of this are described
in EN 50393 and IEC 60502-4.

IEC 60372:2020 is applicable to locking devices used with ball and socket couplings of string insulator units and used with the corresponding metal fittings standardized in IEC 60120, when they are supplied separately.The object of this document is - to define the shapes and some standard dimensions for locking devices, - to define the test methods for locking devices, - to state the acceptance conditions for supply, - to give other dimensions for guidance of manufacturing only. This fourth edition cancels and replaces the third edition published in 1984. This edition includes the following significant technical changes with respect to the previous edition: a. Two new designated size of couplings, 36 and 40, were introduced; b. the relevant content of the 28B W-clip was deleted; c. Annex A is informative, Annex B is normative, Annex C is informative.

Deals with the techniques for sampling free gases from gas-collecting relays and for sampling oil from oil-filled equipment such as power and instrument transformers, reactors, bushings, oil-filled cables and oil-filled tank-type capacitors. Three methods of sampling free gases and three methods of sampling oil are described; the choice between the methods often depends on the apparatus available and on the quantity of oil needed for analysis. Before analysing the gases dissolved in oil, they must first be extracted from the oil. Three basic methods are described, one using extraction by vacuum (Toepler and partial degassing), another by displacement of the dissolved gases by bubbling the carrier gas through the oil sample (stripping), and the last one by partition of gases between the oil sample and a small volume of the carrier gas (head space). The gases are analysed quantitatively after extraction by gas chromatography; a method of analysis is described. Free gases from gas-collecting relays are analysed without preliminary treatment. The preferred method for assuring the performance of the gas extraction and analysis equipment, considered together as a single system, is to degas samples of oil prepared in the laboratory and containing known concentrations of gases (gas-in-oil standards) and quantitatively analyse the gases extracted. Two methods of preparing gas-in-oil standards are described. For daily calibration checks of the chromatograph, it is convenient to use a standard gas mixture containing a suitable known amount of each of the gas components to be in a similar ratio to the commons ratios of the gases extracted from transformer oils. The techniques described take account, on the one hand, of the problems peculiar to analyses associated with acceptance testing in the factory, where gas contents of oil are generally very low and, on the other hand, of the problems imposed by monitoring equipment in the field, where transport of samples may be by un-pre
