IEC 62836:2024提供了一种高效可靠的程序，通过使用压力波传播(PWP)方法来测试用于高压应用的绝缘材料的内部电场。它适用于厚度大于或等于0.5 mm且电场高于1kV/mm的均匀绝缘材料的平面和同轴几何形状样品，但它也取决于样品和压力波发生器的厚度。 第一版取消并取代了2020年发布的IEC TS 62836。 此版本包括以下与IEC TS 62836相关的重大技术变更: a)增加条款12，用于测量平面样品中的空间电荷分布； b)增加同轴几何样品的条款13； c)添加附录D，其中包含同轴几何形状样品的测量示例；d)增加参考书目； e)平面样品的测量示例已从IEC TS 62836中的第12条移至附录C。

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.
