IEC 60092-360 Procedure for Drilling Fluid Immersion Test for SheathsD.1 Drilling Fluid Resistance TestDrilling fluids are used in almost every oilfield drilling operation. The fluids used in the so-called drilling fluid systems may come into contact with cables and may affect the functioning of the cables. The suitability of electric cable sheathing materials, as given in this document, to exposure to these drilling fluids is heavily dependent on the type of drilling fluid present.
D.2 Test Fluids- Be tested in a generic brine-based mud (calcium bromide brine, 45% w/w CaBr₂ in water).
Test Fluids to be Used for the Immersion Test:- IRM 903 oil
- Generic brine-based mud (calcium bromide brine, 45% w/w CaBr₂ in water)
- Oil-based test fluid CAS number
