Except as otherwise specified in the contract or purchase order, the contractor may use
17、 his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assur
18、e supplies and services conform to prescribed requirements. 4.2 Sampling for quality conformance. 4.2.1 Inspection lot. A lot shall consist of all transducer fluid manufactured as one batch. If the material cannot be identified by batch, a lot shall consist of not more than 1,000 gallons of transduc
19、er fluid. 4.2.2. Sampling for examination of filled containers. A random sample of filled containers shall be selected from each lot in accordance with MIL-STD- 105, at inspection level 1, and Acceptable Quality Level (AQL) = 2.5 percent defective. 3 Provided by IHSNot for ResaleNo reproduction or n

From each of these two containers, two 1-quart specimens shall be taken in accordance with ASTM D 923. These spec
21、imens shall be tested in accordance with 4.4 for compliance with 3.2. 4.3 Quality conformance inspection. Quality conformance inspection shall be conducted in accordance with method 9601 of FED-STD-791. 4.3.1 Examination of filled containers. Filled containers shall be exam- ined for defects of the
22、container and the closure, for evidence of leakage, and for unsatisfactory markings. Containers shall also be weighed to determine the amount of the contents. 4.3.2 Rejection of lots, 4.3.2.1 If the number of defective or underf illed containers examined in accordance with 4.3.1 exceeds the acceptan
23、ce number for the appropriate sampling plan of MIL-Sm-105, the lot represented by the sample shall be rejected. 4.3.2.2 If the samples of transducer fluid fail in any of the tests speci- fied in 4.4, the entire lot shall be rejected. 4.4 Tests. 4.4.1 Test methods. Tests shall be conducted in accorda
24、nce with the applicable method given in table II on each l-quart specimen. Each specimen shall be individually identified and marked.

Approximately 30 milliliters (mL) of oil shall be refluxed with an equal volume of acetic anhydride fo
28、r 2 hours in an Erlenmeyer flask, or equal, fitted with a ground-in-air condenser, consisting of a straight glass tube approximately 2 feet in height and 10 millimeters in diameter. At the end of the 2-hour refluxing period, the mixture shall be poured into 500 mL of boiling distilled water containe
29、d in a liter beaker. (A slow stream of carbon dioxide gas shall be passed through the boiling liquid, or add a pinch of pumice, or bits of carborundum brick to prevent bumping at this stage.) Vigorous boiling shall continue for 30 minutes. The mixture shall be allowed to cool slightly and the water
30、shall be siphoned off, removing the last drops with a pipette after tilting the beaker. The boiling and siphoning operations shall be repeated twice. After removing the water, following the third boiling, the still warm acetylated oil shall be transferred to a centrifuge tube and centrifuged to remo
31、ve any remaining water. After centrifuging, two samples of the clear acetylated oil, each of approximately 2.5 grams, shall be carefully removed. The acetylated oil only, shall be removed, without contamination with water. The samples removed shall be transferred to a clean tared 30O-mL Erlenmeyer f
32、lask or equal, and the flask and contents shall be accurately weighed to ascertain the exact weight of sample. The saponification number of the acetylated oil samples shall be determined following the procedure specified in ASTM D 94. The acetyl value shall be calculated as follows: Acetyl value = 1
33、- 2 where SI = Saponification no. of original oil 1 - 0.00075 S1 S2 = Saponification no. of acetylated oil 4.4.3 Solubility. 4.4.3.1 Absolute ethyl alcohol. Fifteen mL of the transducer fluid shall be placed in a 1OO-mL graduated cylinder. Absolute ethyl alcohol in 5- to 10-mL portions shall be pour
34、ed in gradually and shall be shaken after each addition until the 1QO-mL graduation mark is reached. The solution shall be maintained between 65 and 70 degrees Fahrenheit (“F) during the test. The transducer fluid and absolute ethyl alcohol shall be mutually soluble at all concentrations. 4.4.3.2 Ni
35、nety-percent ethyl alcohol. Pure ethyl alcohol shall be diluted with water to a concentration of 90 percent by volume of ethyl alcohol. Ten mL of transducer fluid shall be placed in an Erlenmeyer flask, or equal. The contents shall be maintained at a temperature of 65 to 70F. Forty mL of 90 percent
36、alcohol shall be added gradually, with constant stirring. The transducer fluid shall dissolve completely, forming a clear or not more than faintly turbid solution. 4.4.3.3 Glacial acetic acid. Twelve mL of transducer fluid shall be placed in an Erlenmeyer flask, or equal. The contents shall be maint
37、ained at 65 to 70F. Twenty grams of glacial acetic acid in 1-gram portions shall be added, stirring after each addition. The transducer fluid and glacial acetic acid shall be mutually soluble at all concentrations. 4.5 Inspection of packaging. Sample packages and packs, and the inspec- tion of the p
38、reservation-packaging, packing and marking for shipment and storage shall be in accordance with the requirements of section 5 and the documents specified herein.

39、ion for delivery requirements specified herein apply only for direct Government acquisitions.) 5.1 Packaging and packing. Transducer fluid furnished in one gallon con- tainers shall be packaged and packed for the level specified (see 6.2) in accordance with MIL-STD-290. The type of container shall b
40、e as specified by the contracting activity (see 6.2). Materials used in the construction of containers shall not affect or be affected by the contained transducer fluid. Before filling, all containers shall be thoroughly cleaned and examined to assure absolute absence of dirt, corrosion products, wa
41、ter, or other materials which would either contaminate the oil or interfere with the satisfactory opera- tion of the transducer. 5.2 Marking of shipments. Interior and shipping containers shall be marked in accordance with MIL-STD-290. 5.2.1 Special markings. Containers containing transducer fluid s
42、hall be marked as follows: “Caution - This fluid shall not be used in transducers after initial opening and use.“ 6. NOTES 6.1 Intended use. Primary application of fluid covered by this specifica- tion is for use with sonar transducers aboard ship. 6.2 Ordering data. Acquisition documents should spe
43、cify the following: (a) Title, number, and date of this specification. (b) Quantity of transducer fluid required in gallons. The material should be purchased by volume, the unit being the U.S. gallon at 15.6OC (60OF) (see 5.1). (c) The type of container required (see 5.1). (d) Level of packaging and
44、 packing required (see 5.1). 6.3 Changes from previous issue.
