Chapter 2—ADMINISTRATION, SUPERVISION, AND TRAININGimmediate trouble. As a result of this type ofanalysis, skilled maintenance personnel have beenable to pinpoint wear areas early, and to takecorrective and preventive maintenance actionduring an emergency or on a pre-planned basisas determined by the type of accelerated weardetected. By replacing worn out minor parts amajor failure can be prevented, and the require-ment for costly parts replacements of completeoverhaul of the equipment can be eliminated.Ships shall maintain accurate records ofoperating hours since major overhauls, oilchanges, and samplings in order to provide thetesting facility with the information requested inthe sampling kit. (COMNAVSURFLANT usesthe services of the Charleston Naval Shipyard andCOMNAVSURFPAC uses IntermediateMaintenance Activities (IMA) for analyzing oilsamples from machinery employing closed lubeoil/hydraulic systems.) In addition, a record ofconditions found and repairs effected as a resultof inspections conducted following recom-mendations of the laboratory must also bemaintained.When the shipyard or IMA laboratory receivesthe oil sample, a physical test and a spectrometricanalysis are performed. The physical test consistsof the following:1. All samples are tested for fuel dilution, anda report is provided to all concerned by percentvolume as per requirements of ASTM D92057.2. All samples are tested for solids bycentrifuge to show the amount of suspendedparticles separately from precipitated solids. Thetest must differentiate between those fine particlessuspended by the active compounds in the oil andthose that can settle out of the oil spontaneouslyto give a ratio of colloidal/precipitated solids.3. Allowable “use limits” are tested andrecorded.When the physical test is completed theshipyard/IMAs should make a spectrometricanalysis of each used oil sample, then record andreport to all concerned the concentrations of theElement Concentration InStandard Reference SpecimenStandard Deviation(Range in PPM)(Maximum in PPM)3-91.510 -19220 - 49350 - 995100 - 1998200 - 50015Figure 2-16.—Element Concentrations.following elements in parts per million (ppm).

You must also keep your schedule flexi-ble enough to allow unexpected maintenance and2-19
