ASTM D4049 Standard Test Method for Determining the Resistance of Lubricating Grease to Water Spray
6. Apparatus
6.1 Stainless Steel Test Panel, 18-8 (chromium-nickel) stainless steel, as shown in Fig. 1.
6.1.1 Grease Application Jig, for applying grease to panel; Fig. 2.
6.2 Water Spray Apparatus, as shown in Fig. 3.
6.3 Spray Nozzle, as shown in Fig. 4.
6.4 Thermometer or Thermocouple, capable of measuring 38 +/- 0.5°C, to determine the temperature of the water spray, positioned to prevent breaking the spray pattern.
7. Reagents and Materials
7.1 Purity of Reagents - Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the committee on Analytical Reagents of the American Chemical Society, where such specifications are available. Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination.
7.2 Mineral Spirits, reagent grade, minimum purity. (Warning - Combustible. Vapor harmful.)
7.3 n-Heptane, reagent grade, minimum purity. (Warning - Flammable. Harmful if inhaled.)
