For testing insulating oils with viscosities of 19 mm2/s or below at 40癈, see Test Method D2945. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use." >
找不到引用ASTM D831/D831M-12 电缆及电容器油的气体含量的标准试验方法 的标准

对于润滑油和添加剂来说,在生产、销售和运输的过程中,了解其水含量的多少对预测油品的质量和性能特点有很大的帮助。微量水分的存在将导致润滑油过早的腐蚀和磨损,由此增多的残留物会降低油品的润滑效果,造成过滤器的堵塞,并影响添加剂的功效发挥,更有助于有害细菌的生长。关于油品水分的测试,美国材料与试验协会标准ASTM D6304-20在 2020年作了更新。...
