reagent grade magnesium sulfate, M9S02*7H20,in one liter of boiled distille(water.
4.6.5.1.2 Procedure. Ten ml of undilutedType I cleaning compound and 2grams of Type 11 shall be added to 50ml graduatedcylinders. Fortyml of thesynthetic hard water shall be added to each graduatedcylinder and the contentsshaken vigorously for sixty seconds. Allow each solution to stand undisturbedfor sixteen hours at a temperatureof250~50C (77°&100F). At the end of thesixteen hours examine each solution for separation. After the examination,obtain a measurement of turbidity by using an Orbeca-Helligeturbidimeter8000series or equivalent under the conditionsof no filter and mirror closed.
4.6.5.2 Thermal Stability. Fiftyml of the cleaningcompound at themanufacturer’srecommendedconcentrationshall be placed in a 50 ml graduatedcylinder and stoppered. The cylinder shall be placed in a water bath at60°& l“c (140°~20F) and maintained at that temperaturefor one hour, minimum.At the end of the one-hour period, remove the cylinder from the water bath andexamine the sample for separationor layering.

4.6.5.3 Storaqe Stability. The one gallon plastic container filled withcleaning compound furnished for storage stabilityshall be stored for 6 monthsat 70°& 5°F (21°&30C). In addition,one gallon of the cleaning compoundshall be poured into a glass containerto which has been added a cleaned andpolished,with 280 grit silicon carbide paper, metal strip conforming toMIL-S-7952. The total surface area of the steel strip shall be 38,7 &3.2 sq cw-(6 & 0.5 sq in.). The second gallon shall be stored under the same conditions ‘of time and temperature, After the six month storage period, both samples shallbe tested for cleaning efficiencyand examined for evidence of separation,crystallizationor deterioration,steel corrosion,container incompatibility,distortion,leakage or containercorrosion.

4.6.5.4.1 Preparationof test samDle. A 150ml portion of well shakenundiluted cleaning compound shall be poured into each of two chemically clean500 ml clear, round, screw cap plastic bottles approximately2.5 inches inoutside diameter. One bottle shall be immediatelycapped and stored in the darkfor at least six days at room temperature (controlsample). A strip of steel150 by 125 by 0.5 mm conformingto MIL-S-7952shall be polished with 280 gritsilicon carbide paper to remove surface contaminationand then cleaned byboiling for one minute in chemicallypure isopropylalcohol and one minute inmineral spirits. The steel strip shall be placed in the other test bottle andthe bottle immediately capped (test sample) and thoroughlyshaken for oneminute.
4.6.5.4.2 Procedure. The test sample shall be placed in a water bath, heatedto 39°&20C (100°&40F) and held at that temperaturefor a minimum of 8 hours.The bath shall be cooled to room temperatureover the next 16 hours. This
14
MIL-C-29602
procedure shall be repeated everyday for five additionaldays. After exposurefor a total of six cycles, the test sample shall be removed from the bath andexamined for separationof the cleaning compound. The test sample shall then beuncapped, the steel strip carefullywithdrawn and examined for evidence ofpitting, corrosion or uneven darkening. The test sample shall be recapped and,along with the control sample, thoroughlyshaken for one minute, allowed tostand undisturbed at room temperaturefor a minimum of one hour, then becompared for color and uniformity. Hhen the test sample is in compliancewiththe visual requirements,it shall be tested for cleaning efficiency (4.6.6) forconformance to 3.10.4 requirements.
4.6.6 Cleanina efficiency.The cleaning compound solution shall be preparedby diluting the cleaning compound to the manufacturer’sreconxnendedconcentrationwith distilledwater.

The panels shall be solventwiped with acetone (dimethylketone)using CCC-C-46 Class 7 aerospacewipes. Thepre-cleaning shall continue until the wipe is free from visual residue. Dry thepanels in an oven maintained at 105°&20C (22°~40F) for 30 minutes. Thepanels shall then be removed from the oven, air-cooledto room temperature andweighed to the nearest 0.1 mg (Wl).
4.6.6.3 Amaratus. The clcaning apparatusshall be capable of completelyimmersing and removing the panel verticallyat a rate of 20~ 1 cycles perminute for the clean and rinse test method while maintaininga constanttemperature of 71° & 1°C (160°~ 2°F) (see Figure 2).
4.6,6.4 Soil removal. Prepare 1000ml of the cleaning solution’accordingtothe manufacturer’s recommendedconcentration. App~y approximately75 mg of theoiJ/carbon black soil by brush and uniformlycoat panel by swiping with aScotchbrite fine abrasivemat (3M Companyor equivalent). Aciipping machinesimilar to the Fisher-PayneDipcoatershall be used to give a uniform coating ofthe MIL-C-81309 Type IS soil. The panel should be immersedto the shoulder in15 to 20 seconds and removed in approximately70 seconds.All panels shall beplaced in a 105°&20C (221°&40F) oven for one hour. The panels shall then beair-cooled to room temperatureand weighed to the nearest 0.1 mg (Wz). Only usepanels with more than 60mg and less than 90mg of soil. The cleaning test
15
MIL-C-29602
shall be run at 71°~ 1°C (160°&20F). The cleaner shall be maintained at thespecified temperaturethroughoutthe test. TWO soiled panels shall besimultaneouslyimmersed and withdrawn from the cleaning solution at a rate of20 & 1 cycles per minute for a period of five minutes. The panels shall then berinsed for 60& 1 seconds in distilledwater using the same equipment andprocedure. The panels shall then be dried for one hour at 105°i20C(221°& 4°F). The panels shall be air-cooledand re-weighed (W3). The percentsoil removal (cleaningefficiency)shall be calculatedas follows:
Percent soil removal = 100X (W2 - w3)/ (11~- w,)
Three trials shall be used for this test when determiningthe average of thecleaning efficiency.
4.6.7 Service Test.
4.6,7.1 Eaui~ment. A cabinet style parts washer capable of spray washing ata nozzle pressure of 50 psi minimum and 110 psi maximum shall be charged withthe cleaning compound at the manufacturer’srecommendedconcentration. Thesolution shall be stabilizedat 71°&60C (160°& 10°F) prior to initiation ofthe service test.
4.6.7.2 Test SDecimens. Aminimum of three transmissionor engine componentsshall be selected for the service test. Componentsshall be representativeofactual shapes and configurationsencounteredduring normal cleaning. Componentsshall weigh a maximum of three pounds so that soil weight can adequately bemeasured. At 1east one componentshal1 be of a 1ow carbon steel so that f1ashrusting concerns may be addressed. Componentsshall be cleaned by glass beadblasting followed by immersionin an aqueous ultrasoniccleaner or by anequivalent method. Initial cleanlinessshall be determinedby visual inspectionto verify the absence of any detergentfilm and blast residue particles, andbacklight inspectionto verify the absence of any residual oils on the surfaceprior to beginning the service test.
4.6.7.3 Soilin~ Procedures. A standard soil shal1 be prepared by combiningtransmission fluid (DOD-L-85734)or lubricatingfluid (MIL-L-23699)with carbonblack in a ratioof5 parts carbon btackto 100 parts fluid by$veight. Soilshall be applied to the componentsusing an appropriatebrush or wiping cloth,The soiled components shall then be baked at 104°&30C (220°&50F) for 1 hour.Components shall be weighed before soiling and just prior to cleaning to providea means to quantify soil removal.
4.6.7.4 Cleaning. The componentsshall be cleaned in a normal wash cycle for30 minutes. The components shall be cleaned in the candidatematerial twotimes: Once with an automaticrinse cycle and once without rinsing. Thestandard soiling procedure outlined in 4.6.7.3 shall be followed prior to eachof the cleaning cycles.
