A suitable label with the following instructions printed ther
29、eon shall be attached to each container: Instructions for use: The cleaning compound may be used by soak, brush, or spray application. Do not dilute. Allow the cleaning compound to remain on work for 3 to 5 minutes before rinsing. Two recommended procedures for spray application are as follows: Meth
30、od 1: Apply the compound by spray gun at a pressure of 27.5 kPa (4 psi). Hold the spray nozzle or the gun about 15 cm (6 inches) away from the work. Use a heavy stream of liquid rather than dispersion. Examine the soil 3 to 5 minutes after application. If the soil has not softened, spray a second ap
31、plication of the compound. Allow 3 to 5 minutes, then rinse by means of a “Steam Jenny“ or equivalent device at a pressure of 275 to 350 kPa (40 to 50 psi), or if not available, then with hot water, preferably at a pressure of 175 to 350 kPa (25 to 50 psi). If water must be avoided, rinse with Stodd
32、ard solvent. Method 2: Apply compound by spray gun at a pressure of 140 kPa (20 psi). Hold the spray nozzle or the gun about 15 cm (6 inches) away from the work. Do not rinse. In this method, the compound may be repeatedly recycled and reused. Provided by IHSNot for ResaleNo reproduction or networki

May be irritating to skin, eyes, and respiratory tract. Protect hands by wearing gloves when using this material. If skin or eye con
34、tact occurs, flush with large amounts of water. Do not take internally. CAUTION: DO NOT USE ON ACRYLIC PLASTICS. Care should be exercised when using this solvent on other plastics, rubber, etc., including pretesting on the specific material to insure no deleterious effects. 3.6.1 Container label. In
35、formation on the container label shall include the flash point as determined by the Pensky-Martens closed cup tester method using ASTM D93. Labeling for this product must be in compliance with 49 CFR 100 - 185. 3.7 Toxicity. The cleaning compound shall have no adverse effect on the health of the per
36、sonnel when used for its intended purpose. Questions pertinent to this effect shall be referred by the contracting activity to the appropriate departmental medical service who will act as an advisor to the contracting agency. 3.8 Workmanship. The ingredients shall be carefully formulated to produce
37、a cleaning compound that is stable. The product shall be homogeneous and be free from abrasive materials. 4. VERIFICATION 4.1 Inspection conditions. Unless otherwise specified (see 6.2), all inspections shall be performed on each lot. A lot shall consist of the cleaning compound produced by one manu
38、facturer in no more than 24 hours, at one plant, from the same materials, and under essentially the same manufacturing conditions, provided the operation is continuous. In the event the process is a batch process, each batch shall constitute a lot. 4.2 Conformance inspection. The conformance inspect
39、ion shall be performed on representative samples. Sampling shall be conducted in accordance with table III. This inspection shall include the requirements of 3.3 through 3.8 and the tests of 4.3. Failure of any verification or test by any sample shall be cause for rejection of the lot represented. P

A representative specimen of approximately 2 liters (L) (2 quarts) shall be removed from each sample container and placed in a suitable, clean, dry container labeled to identify the lot or batch and the
42、 container from which it was taken. 4.3.2 Validation for high-flash point naphtha characteristics or change of supplier. When a contractor wishes to change the cleaning compound formulation by substituting a high-flash point naphtha not already used in an approved formulation, or one from a new supp
43、lier, a half-liter (one pint) sample of the new high-flash point naphtha, together with a request for a waiver for its use, must be forwarded to DLA Aviation - FAJA, 8000 Jefferson Davis Highway, Richmond, VA 23297-5616. 4.3.3 Reagents. All chemical materials employed as reagents in chemical composi
44、tion testing shall be of reagent grade in accordance with the appropriate material specification. 4.3.4 Phenolic or cresylic acids or their salts. 4.3.4.1 Sample preparation. Measure 50 milliliters (mL) of the cleaning compound into a clean 250-mL separatory funnel. Add 100 mL of 0.05 mol/L calcium
45、hydroxide solution. Shake vigorously for 2 minutes, venting frequently. Allow layers to separate, and then transfer the aqueous layer to a 500-mL volumetric flask. Repeat the extraction two more times, combining the aqueous layers. Dilute the combined extracts to volume with distilled water. 4.3.4.2
46、 Analysis. Analyze the sample according to method B of ASTM D1783. The preliminary distillation step described in the method is required. The pH of the sample shall be checked prior to distillation and again prior to analysis and adjusted as necessary to meet the limits required by the method. Using
47、 the above extraction technique, the detection limit of the test method is 0.5 milligram/liter (mg/L).

48、hod described in 4.3.5.1 or 4.3.5.2 may be used for determining halogen content. The second method, bomb combustion/mercurimetric nitrate titration, is simpler and will normally be the method of choice. While both methods are intended for determination of chlorine, the other halogens are positive in
49、terferences. Therefore, results should be reported as “total halogens as chlorine“ rather than “total chlorine“. 4.3.5.1 Bomb combustion/gravimetric method. Prepare and analyze the sample as directed in ASTM D808. The detection limit for this test method is 0.1 percent chlorine. 4.3.5.2 Bomb combustion/mercurimetric nitrate titration method. Combust the sample as directed in ASTM D80
