          This procedure is used to determine the resistance to coating adhesion loss of coated surfaces of aluminum,plastic, steel, and other substrates when subjected to a wet blast similar to that produced by vehicle wash equipment.

                 a   4.7 mm ID tube. A substantially non-diverging discharge is required for this test (**) 
               (see Figures 1 and 2).
          Note:  Electro-Magic Model 100 (and the earlier Model 60) Steam Generator available only 
                from:Atomic Cleaning Systems, 31651 West Eight Mile Road, Livonia, MI 48150, Phone: 
                 (248) 615-4400, has been found to be satisfactory. The Model 100 or Model 60 are no 
                 longermanufactured directly by Electro-Magic. However, Atomic Cleaning Systems is
                 capable ofmodifying new Electro-Magic models to meet the Model 100 specifications
                 required for this test.Milwaukee 1/2 inch globe valve No. 1151-1161, 150 SWP 300 WOg
                is adequate for use in  standardization of generator.
          Model 100 Steam Generator
              The pumping pressure is directly related to the input flow rate. The pressure needed for
                  therequired flow can be determined by measuring the pump pressure and discharge
                  flow rate withthe burner off. When the burner is turned on, the required flow rate is
                  obtained by readjusting to the required pump pressure.
              This is done by placing the tube midstream 25 mm from the nozzle. The tube size must  
                   not bevaried because the densities and velocities are not uniform throughout the cross
                  section of thedischarge stream.
            Adjusting the discharge dynamic head may be required. This must be done in such a
                way thatthe input flow rate as specified in Para (a) above is maintained. This is done by
               adjusting the amount of heat transferred to the water. Increasing the heat will cause the
               flow rate (pressure) of (a) to change. It must be readjusted. This operation will result in an
                increased dynamic pressure; to decrease it, decrease the heat and then adjust the flow
              (pressure).

          Thermometer
                 Capable of measuring 100 +/- 2 °C
          Face Mask
                Full face cover safety mask is required when performing this test.
          Gloves
               Gauntlet-type gloves for protection of hands are required.


                                              Conditioning and Test Conditions
            All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 ??C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified.

                                                                    Procedure
          1.  Standardize the Model 60 or Model 100 Steam Generator.
              a.  Measure and maintain the input flow at 2.7 L/min. Install a 12.5 mm globe valve in the
                  steam line between coil weld assembly and a 5/32 inch hose nipple. With burner off,
                   engage pump and adjust globe valve until 2.7 L/min is obtained.
                  Record the tank pressure that is obtained with the 2.7 L/min flow rate. (This induced
                   back pressure simulates the pressure that steam exerts on the system while the burner
                   is on.)
             b.  Measure and maintain the mean dynamic head at 37.9 kPa (5.5 psi) using the fixtures as
                 described in Figures 1 and 2. Open globe valve and turn on the burner. Allow tank
                 pressure   tostabilize before reading the mean dynamic head. Adjustments of the
                 dynamic head are to be  made by changing the amount of heat transferred to the water
                 at the burner. (The flow  rate, as  specified above, must be maintained.)
              c.  Measure and maintain a 98 +/- 2 °C temperature of the steam blast at the test
                  sitedistance.

          2.    Measure film thickness per Ford Laboratory Test Method BI 117-01 at proposed test sites
               and record.
          3.  Immerse the parts or panels (previously prepared per Engineering Materials Specification)
               in the water immersion tank for four hours at 38 +/- 2 °C. Aerate the water by placing 6.5
               mm ID plastic tube at the bottom of the tank and bubble air at a rate of one bubble per
               second minimum. Maintain a 5 ppm maximum dissolved solids (as NaCl) in the water.
               Check and record NaCl level using a dissolved solids meter.
          4.  Remove the samples after four hours of water immersion and cut an "X" through the
                coating into the substrate across the panel or part where feasible (see Figure 3).
                a.  Use a scribe to make the cut if the substrate is metal or hard, rigid plastic.
                b.  Use a utility knife to make the cut if substrate is an elastomeric material.
          5.  Place the test samples in a freezer at minus 29 +/- 2 °C for a three hour minimum freeze
              cycle.
          6.  Within 30 seconds from freezer removal, direct the steam blast at the center of the "X" cut,
              at a distance  of 2 to 3 inches and 45° to the sample, in the direction shown in Figure 3.

           Note:  High pressure wet steam represents a potential safety hazard. Not only is it necessary|
                      to secure the samples properly, but full face protection and gloves are required.
          7.  After 30 seconds, record area (mm2) of coating removal by visually measuring with a
                metric ruler  (typical triangular coating removal: Area = 1/2 Base x Height). Also examine
                the surface and report  any blushing, whitening, or loss of gloss.
          8. If a failure occurs, note number of seconds after steam black initiated that the failure 
                occurred.


          Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly.
