Testing corrosivity of transformer oil

Testing corrosivity of transformer oil

Testing corrosivity of transformer oil

(OP)
I need to adopt a test for the corrosivity of transformer oil. Standards that I am aware of are IEC 62535, ASTM D130 or DIN 51353, but I only have access to titles, not the standards themselves (without buying all three). Any recommendations on which to go with, or are they equivalent?

a. IEC 62535: Test method for detection of potentially corrosive sulfur
in used and unused insulating oil.

b. ASTM D130: Standard test method for corrosiveness to copper from
petroleum products by copper strip test.

c. DIN 51353: Testing of insulating oils; detection of corrosive
sulfur; silver strip test.

RE: Testing corrosivity of transformer oil

It all depends on which oil sample you are going to test.If you want to check very old oil, say before 1985 vintage when hydrocracking was not used for making oil, the relevant standards are DIN 51353 & ASTM D310 which are identical. These tests detect free corrosive sulphur present in oil.

In case you are concerned with potentially corrosive sulphur (started with highly refined oil marketed from early 1990's to mid 2000's, you may use IEC 62535 ed1.0( 2008-10) Equivalent standards are ATM D 1275-96 Method A &B or Doble CCD Test.This phenomena was more with oil containing additive DBDS(dibenzyl disulphide ) which used to be added to oil to get better oxidation stability.There is a standard for detection of DBDS in oil -IEC 62597-1 ed1.0(2012-08)
