IP 315 - Corrosive Sulfur in Electrical Insulating Oils - Copper Corrosion

We perform oil quality testing by IP 315 to detect the presence of free sulfur and corrosive sulfur compounds in oil by putting it in contact with copper. Most applications for insulating oils put the oil in constant contact with metals that are subject to corrosion. Any corrosive sulfur compounds in the insulating oils will cause deterioration and corrosion in those metals, leading to mechanical failure and operating problems. IP 315 detects the presence of free sulfur and corrosive sulfur compounds by putting copper in contact with an oil sample under controlled conditions.

We also perform copper corrosion testing by ASTM D1275ASTM D130ASTM D4048DIN 51811FTM 5305ISO 2160ISO 5662MIL-PRF-372E §4.3.2, and MIL-PRF-46002 § These different test methods use different instruments or procedures or are used for certain sample types.

IP 315 corresponds to ASTM D1275 and ISO 5662.
