IEC 62836:2024 provides an efficient and reliable procedure to test the internal electric field in the insulating materials used for high-voltage applications, by using the pressure wave propagation (PWP) method. It is suitable for a planar and coaxial geometry sample with homogeneous insulating materials of thickness larger or equal to 0,5 mm and an electric field higher than 1 kV/mm, but it is also dependent on the thickness of the sample and the pressure wave generator. This first edition cancels and replaces IEC TS 62836 published in 2020. This edition includes the following significant technical changes with respect to IEC TS 62836: a) addition of Clause 12 for the measurement of space charge distribution in a planar sample; b) addition of Clause 13 for coaxial geometry samples; c) addition of Annex D with measurement examples for coaxial geometry samples; d) addition of a Bibliography; e) measurement examples for a planar sample have been moved from Clause 12 in IEC TS 62836 to Annex C.

IEC TS 62749:2020 is available as IEC TS 62749:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC TS 62749:2020 specifies the expected characteristics of electricity at the SUPPLY TERMINALS of public low, medium and high voltage, 50 Hz or 60 Hz, networks. NOTE 1 The boundaries between the various voltage levels can be different for different countries/regions. In the context of this TS, the following terms for system voltage are used: - low voltage (LV) refers to less than or equal to 1 kV; - medium voltage (MV) refers to between 1 kV and 35 kV; - high voltage (HV) refers to between 35 kV and 230 kV. While power quality is related to EMC in a number of ways this document is not an EMC publication. This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) minimum number of remaining data for weekly analysis, b) improvement of the compatibility between EN 50160 and IEC TS 62749, c) further explanation of the conception of daily sliding window, d) further explanation of the aggregation method used for events, e) further explanation of the relation between Power Quality and EMC, f) addition of a new definition of mains communicating system (MCS), g) addition of a new Annex G: Other phenomena, h) transfer of the main content of IEC TR 62510 to IEC TS 62749.
