2、 SURFACES Application This method outlines the procedure for coating steel surfaces such as lab-test panels with oil films of reproducible thickness. Apparatus Required Dipping Tank Shall be suitable for immersion of lab-test panels. The tank shall be so designed to expose a minimum of the oil solut
3、ion to the atmosphere (to avoid loss of solvent by evaporation). Mechanical Convection Oven Must be capable of maintaining 50 +/- 2 C. Materials Required Oil Anticorit 4107 S: Source: Fuchs Petrolub AG 68169 Mannheim Friesenheimerstr. 19, Germany Solvent N-Hexan (altern. N-Heptan) CAUTION: low flash
4、 point. Lint-Free Cloth 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

Preparation of Oiling Solutions 1. Blend the specified solution to the following rat
6、io: Oil Solution Oiling Grade Anticorit 4107 S N-Hexane 1. Nominal oil film weight 1.25 +/- 0,25 g/m 3% +/- 1% by volume 97% +/- 1% by volume 2. Maximum oil film weight 3.00 +/- 0,30 g/m 7% +/- 1% by volume 93% +/- 1% by volume Cleaning and Coating the Steel Surface 1. Clean the steel surface with t
7、he lint-free cloth soaked with the solvent. Rinse both sides of the steel surface with the same solvent until no process traces remain on the surface. 2. Allow to dry at room temperature (23 +/- 2 C) until the n-hexane has completely evaporated. 3. Immediately after air drying, immerse the steel pan
8、el in the tank filled with one of the oil solutions, as outlined above, in accordance with the oil grade required by the applicable Engineering Specification. Dip, vertically, in such a manner that after removal the solution drainage occurs across the shortest surface. 4. After immersion for 1 minut
9、e, remove the steel part from the solution. 5. Allow the steel part to drain in a vertical position for 10 minutes at room temperature. 6. Check the Oil Coating/Weight as specified by the Engineering Specification. A test panel prepared per para 1 + 2 is weighed on an analytic scale with a precision
10、 of 0.001 g. After oiling per para 3 5 weigh again. The oil coating in g/m is derived from the weight difference in relation with the panel-dimensions. If the oil-weight deviates approx. 10% from the specified oil-weight, the panel can be used. FORD LABORATORY TEST METHODBZ 150-11Printed copies are

Rinse both sides of the steel surface with the same solvent until no process traces remain on the surface. 2. Allow to dry at ambient-temperatu
12、re (23 +/- 2 C) until the n-hexane has completely evaporated. 3. The cleaned panel should be warmed up for a short time (approx. 5 Min. 30 50 C) in a mechanical convection oven (for better oil-distribution). 4. Apply some drops of oil with a drip oiler, dropping pipette or other suitable device on t
13、he panel and distribute them even over the panel with a lint-free cloth. 5. Check the Oil Coating/Weight as specified by the Engineering Specification. A test panel prepared per para 1 + 2 is weighed on an analytic scale with a precision of 0.001 g. After oiling per para 3 + 4 weigh again. The oil c
14、oating in g/m is derived from the weight difference in relation with the panel-dimensions. If the oil-weight deviates approx. 10% from the specified oil-weight, the panel can be used. Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities.
