If the number of defective or under-filled containers exceeds the acceptance number for the appropriate sampling plan, reject the lot repres

31、ented by the sample. 4.4 Test methods. All tests are classified as quality conformance tests. Perform tests and evaluations in accordance with the applicable test methods given in table III and paragraphs 4.4.1 through 4.4.7. TABLE III. Test methods.

32、 content ASTM D 95 Pour point ASTM D 97 Flash point ASTM D 921 1Before determining the flash point, heat the sample to 220 F (104 C) for one hour in a low- form evaporating dish having an open surface approximately 10 cm in diameter to remove water that might interfere with the flash point determina

33、tion. 4.4.1 Storage stability. Pour a 100 mL sample of the emulsifiable oil into a 100-mL glass-stoppered graduated cylinder and store it for 168 hours in an oven maintained at 130 F 5 F (54 C 3 C). Remove the cylinder from the oven and allow the sample to cool to room temperature 77 F 5 F (25 C 3 C

34、). Examine the sample visually for separation or gelling. If none is observed, store the sample at 40 F 2 F (4 C 1 C) for 4 hours. Allow it to warm to room temperature, and examine it for separation and gelling again. If none is observed, save the sample for the emulsion stability test (see 4.4.2).

35、Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-VV-C-846D 6 4.4.2 Emulsion stability. Pour 95 mL of synthetic hard water (see 6.3.2) into a 100-mL glass-stoppered graduated cylinder. Cool the water to 45 F 2 F (7 C 1 C) and add 5 mL of emulsifiable o

36、il that has passed the storage stability test (see 4.4.1). Agitate the contents vigorously by inverting the cylinder 100 to 120 times within a period of one minute. Allow the mixture to stand for 24 hours at room temperature 77 F 5 F (25 C 3 C) and examine it for separation and sedimentation. 4.4.3

37、Frothing. Pour 190 mL of reagent-grade water (see 6.3.1) into a 250-mL glass-stoppered graduated cylinder. Add 10 mL of emulsifiable oil. Agitate the contents vigorously by inverting the stoppered cylinder 100 to 120 times within a period of one minute. Allow the cylinder to stand for 15 minutes at

38、a temperature of 77 F 5 F (25 C 3 C) and record the volume of froth at the top of the emulsion. 4.4.4 Gumming. Prepare 100 mL of emulsion as described in 4.4.2 and pour it into a 100-mL beaker. Place the uncovered beaker in a forced draft oven maintained at 160 F 5 F (71 C 3 C) for 16 hours. Remove

39、the beaker from the oven and allow it and the residue to cool to room temperature. Add 10 mL of reagent-grade water and stir the contents vigorously for one minute with a glass rod. Examine the mixture for undissolved solids, polymerized particles, or gels. The presence of any one of these substance

40、s constitutes gumminess. If no gumminess is found, add 80 mL of reagent-grade water to the beaker and stir the contents for one minute. Transfer the mixture to a 100-mL glass-stoppered graduated cylinder that has one milliliter subdivisions and fill it to the 100-mL mark with reagent-grade water. Mi

41、x the contents by inverting the cylinder several times and allow it to stand for one hour. Examine the upper part of the fluid and record the volume of any separated oil. 4.4.5 Corrosion. The corrosion test shall be performed according to paragraphs 4.4.5.1 through 4.4.5.5. After completion of the c

42、orrosion test, examine and compare both the exposed and duplicate metal strips under 5X magnification to determine whether staining, pitting, or etching has occurred on the exposed strips. 4.4.5.1 Procedure. Prepare two strips, each measuring approximately 3 X 1/2 X 1/8 inches, of each type of metal

43、 listed in table IV in accordance with ASTM D 130. Using forceps, place one strip of each type of metal in a separate test tube that measures approximately 32 millimeters (mm) outside diameter by 2,000 mm in length. Place the duplicate strips in a bottle filled with the commercial grade normal hexan

44、e. Keep this bottle tightly stoppered until time to examine the strips. CAUTION: Normal hexane is flammable. Use only in a well ventilated area. Keep all flames away from the normal hexane.

Prepare a solution of the cutting fluid by placing 190 mL of reagent-grade water and 10 mL of the cutting fluid in a 250-mL graduated cylinder. Stopper the graduated cylinder and invert it s

47、everal times. Continue inverting the graduated cylinder until a uniform mixture is obtained. Place 50 mL of the cutting fluid solution in each of the four test tubes. Mark the fluid level on the outside of each test tube and maintain this level by the addition of distilled water during the course of

48、 this test. 4.4.5.3 Bubble tower preparation. Fill a 500-mL bubble tower with the sodium hydroxide solution and connect the tower, through the air pressure regulator, to a source of clean, compressed air by means of the rubber tubing. Connect each length of glass tubing, by means of rubber tubing an

49、d an appropriate manifold or series of Y-tubes, to the discharge outlet of the bubble tower. Place a screw type pinch clamp on each piece of rubber tubing leading to the glass tubes. 4.4.5.4 Test execution. Insert each glass tube to the bottom of a test tube and adjust the air flow into each tube to produce approximately one bubble per second by means of the a
