ASTM D1534Standard Test Method for Approximate Acidity in Electrical Insulating Liquids by Color-Indicator Titration
ASTM D1534用比色指示剂滴定法测定电绝缘液近似酸度标准试验方法
The approximate acidity of used electrical insulating oils is an estimate of the total acid value of the oil. As acid values increase, oil quality decreases. This is usually due to oxidation of the oil while in service. In general, acidic by-products produce increased dielectric loss, increased corrosivity, and may cause
