REQUIREMEWI“T 3.1 Preproduction samples. Unless otherwise
7、 specified in the contract or order, preproduction samples of the pentaerythritol dioleate shall be manufactured using the rhethods and procedures, proposed for the production. The sample shall be tested as specified in Section 4 herein and is for the purpose of determining that, prior to starting p
8、roduction, the contractors production methods are capable of yielding items that comply with the technical requirements of the contract. After satisfactorily passing all the preproduction tests specified herein, no changes in raw materials and processing of materials for production shall be made wit
9、hout prior written approval of the procuring activity. ( 3.2 Data requirements. No data is required by this specification or by applicable documents referenced in Section 2 unless specified in the contract or order (see 6.2). 3.3 Physical and chemical properties 3.3.1 Saponification number.

11、 MIL-P- 81237(wP) I 3,3.3 Acid number. The acid number of the pentaerythritol dioleate shall be a maximum of 7.5. 3.4 Workmanship. The material shall be uniform in quality and shall I be free from impurities and other defects that could adversely affect its use. 4. QUALITY ASSURANCE PROVISIONS 4.1 R
12、esponsibility for inspection. Unless otherwise specified in the contract or purchase order, the supplier is responsible for the performance of all inspection requirements as specified herein. Excepl as otherwise specified, the supplier may utilize his own facilities or any commercial laboratory acce
13、ptable to 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 assure supplies and services conform to prescribed requirements . 4.2 Classification of inspections. Inspection of the pentaeryt
14、hritol dioleate shall be classified as follows: a. Preproduction inspectim (see 4.4) bo Quality conformance inspection (see 4,s) 4.3 Sampling I 4.3.1 Preproduction sample, After mixing until the material is homo- geneous, a preproduction sample of four, 8-ounce samples shall be removed from each con
15、tainer. Combine any two of the four samples to form a composite sample. Repeat with the remaining two samples to form the second composite sample. Each composite sample manufactured in accord- ance with 3.1 shall be subjected to the preproduction tests detailed in 4.4 at an activity designated by th
16、e procuring activity. Further production of the pentaerythritol dioleate by the supplier, prior to approval of the pre- production sample, shall be at the suppliers risk. 4.3.2 Quality conformance inspection sampling. Unless otherwise specified, sufficient material shall be taken from each lot to pe
17、rform the tests as specified in 4.5.

An inspection lot of pentaerythritol dioleate shall consist of all material presented for ac
18、ceptance at one time and produced in a single manufacturing batch under homogeneous conditions of manufacture. 4.4 Preproduction inspection. The preproduction sample shall satis - factorily pass the quality conformance inspections detailed in 4.5. 4.5 Quality conformance inspection 4.5.1 Visual exam
19、ination. Visually examine all containers in the lot to determine compliance with 3.4 and Section 5. 4.5.2 Saponification number test. Transfer approximately 3.5 grams weighed to the nearest 0.1 milligram (mg) of the sample into a 300 milli- liter (mi) ground-glass Erlenmeyer or round-bottom flask. A
20、dd 50 ml of approximately O. 5 normal (N) alcoholic potassium hydroxide solution. Connect the flask to an air condenser, approximately 250 millimter (mm) in length, and reflux for 3 hours on a steam bath at such a rate that the major portion of the alcohol will condense in the lower half of the cond
21、enser. Allow the flask and contents to cool to room temperature. Remove the condenser and rinse with three 10-ml portions of neutralized 95-percent alcohol, collecting the washings in the flask, Add 2 or 3 drops of 1-percent phenolphthalein indicator to the flask contents, and titrate with standardi
22、zed 0.5N hydrochloric acid to the appearance of colorless solution. Make a blank determination on 50 mi of the alcoholic potassium hydroxide solution in accordance with this procedure. Calculate the saponification number as f ollows : 56.1 (C-B) N Saponification number = W where: B = ml of hydrochlo
23、ric acid required to titrate the sample C = ml of hydrochloric acid required for blank titration N = Normality of hydrochloric acid solution W = Weight of sample, grams Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-NIL-P-83237 hi3 m 7797706 0322734
24、 7 m . MIL - P- 81237 ( WP) a 4.5.3 Color. Prepare a set of Gardner color standards according to M-TM D 1544-581. Fill a Gardner sample tube and compare the color of the sample to that of the standard. Record the number of the standard that most closely matches the sample as the color of the sample.
25、 4.5.4 Acid number. To 150 ml of absolute ethanol in a 250-ml flask add 2 drops of 1-percent phenolphthalein indicator. Titrata with 0.1 N sodium hydroxide to a faint pink end point that persists for at least 30 seconds. Add about 10 grams of composite sample, weighed to the nearest 0.1 mg, and stir
26、 to dissolve, warming slightly if necessary. Titrate the sample solution with 0.1 N sodium hydroxide to the faint pink end point that persists for at least 30 seconds. Calculate the acid number as follows: .I 56.1 X V X N W Acid number = where: V = Volume of sodium hydroxide to titrate sample soluti

Failure of any preproduction or quality conformance sample to comply with any requirement of this specification shall be cause for rejection of the lot. 5.
