9、ght steels43.Summary of Test Method3.1 This test method is divided into two parts:3.1.1 Part AUsed only for fluids where water is thecontinuous phase.Examples of such fluids include water-glycol hydraulic fluids and high-water-content hydraulic fluids.Do not use Part A to evaluate invert emulsion hy

10、draulic fluids.3.1.2 Part BUsed for both water-containing fluids andcompletely water-free fluids such as petroleum based hydraulicfluids,except phosphate esters.In Part B a small beaker ofwater is present to provide water vapor to cause corrosion inthe absence of a vapor-phase inhibitor in the fluid

11、.Part B is theappropriate procedure for evaluating invert emulsion hydraulicfluids.3.2 In both Part A and Part B,a steel specimen is attachedto the underside of the cover of a beaker containing the fluidunder test.The apparatus and specimen are identical to those ofTest Method D3603.The fluid is bro
