IEC 60156:2018 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 60156:2018规定了确定绝缘液体在工频下的介电击穿电压的方法。测试程序在指定的设备中进行，其中油样品经受增加的交流电场，直到发生击穿。该方法适用于在40℃下标称粘度高达350 mm2/s的所有类型的绝缘液体。它既适用于交付时未使用的液体的验收测试，也适用于确定在设备监控和维护中采集的样品的状况。这第三版取消并取代了1995年出版的第二版。这一版本构成了一个技术修订，主要是确认了前一版本的内容，即使包括了一些进步。由于世界各地分布着大量的仪器，即使现在建议使用搅拌，测试方法也没有因实际原因而改变。

IEC 60156:2018 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

IEC 60156:2018 specifies the method for determining the dielectric breakdown voltage of insulating liquids at power frequency. The test procedure is performed in a specified apparatus, where the oil sample is subjected to an increasing AC electrical field until breakdown occurs. The method applies to all types of insulating liquids of nominal viscosity up to 350 mm2/s at 40 °C. It is appropriate both for acceptance testing on unused liquids at the time of their delivery and for establishing the condition of samples taken in monitoring and maintenance of equipment. This third edition cancels and replaces the second edition published in 1995. This edition constitutes a technical revision and, mainly, confirms the content of the previous edition even if some advances are included. The test method has not been changed for practical reason due to the very large number of instrumentation disseminated around the world, even if the use of stirring is now recommended.
