21、ormulation of an approved product shall require requalification (see 3.3.2, 4.3 and 6.3). 3.2 Materials. Component materials used in the manufacture of the hydraulic fluid shall be of high quality, suitable for the purpose intended, and when finally blended shall form a fire resistant fluid meeting
22、the requirements of this specifi- cation. 3.2.1 Additives. The hydraulic fluid shall contain additive materials to pro- vide lubrication, corrosion prevention and viscosity temperature characteristics. There shall be no other restrictions on the type of material used in the fluid ex- cept those impo
23、sed by the requirements of this specification. 3.2.2 Color. A water soluable red dye shall be added to the hydraulic fluid to improve visibility in liquid level gauges. A desirable color is obtained when 5 parts of “Pontamine Fast Red 8BNL Concentrated 175 percent“ as manufactured by E.I. Dupont de
24、Nemours, Wilmington, Delaware, or an equivalent dye, is added to 100,000 parts by weight of an amber (ASTM Color Number 1-1/2 to 2) fluid. 3.3 Compatibility. 3.3.1 With previously qualified fluids. When the hydraulic fluid being tested is added to all previously qualified fluids to make a mixture co
25、nsisting of equal volumes of the fhid being tested and each of those previously qualified, the mixture shall not form resinous gums, sludge or insoluble solid materials and shall comply with the viscosity requirements specified in 3.4. No further efforts to- wards qualifying a fluid shall be conduct
26、ed if the mixture does not comply with thi S requi rement. 3.3.2 Fluid mixtures. The Government reserves the right to require that a fluid submitted for qualification comply with all of the qualification require- ments of this specification when mixed with other previously qualified fluids, irrespec
27、tive of the proportions of the fluid constituting the mixture. 3.4 Chemical and physical properti es. The chemical and physical properties shall conform to Table I, when tested as specified in 4.6.2. 3.5 Material safety data sheets. Material safety data sheets shall be prepared and submitted in acco
28、rdance with FED-STD-313. Material safety data sheets shall also be forwarded to the qualifying activity specified in 4.3-.1. The hydraulic fluid shall have no adverse effect on the health of personnel including contact dermatitis (see 4.6.15). The fluid shall contain no components which produce noxi
29、ous vapors in such concentrations as to be an annoyance to personnel during formulation or use. The properties of the fluid shall be such that its use shall not require personnel protective equipment, special control procedures or special hand1 ing techniques. Questions pertinent to this effect shal
30、l be referred by the contracting activity to the appropriate departmental medical service who wi 11 act as an advisor to the contracting agency (see 4.3.1 and 6.2.le). 3.6 Workmanship. The hydraulic fluid shall be free from oil, dirt, lint, sediment, and lumps of undissolved additives. The fluid sha
31、ll be filtered through a non-absorptive type of filter just prior to final packaging.

QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspe
32、ction. Unless otherwise specified in the contract or purchase order , the contractor i S responsible for the performance of al 1 inspection requirements as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other faci 1 i ties sui
33、table 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 assure supplies and services conform to p
34、rescribed requi rements. 4.2 Classification of inspection. The inspection requirements specified herein are classified as fol lows: a. Qualification inspection (see 4.3). b. Quality conformance inspection (see 4.4). 4.3 Qualification inspection. The qualification inspection shall consist of a review
35、 for approval of the submitted manufacturers test reports and subjecting the qualification sample (4.3.1) to examination and testing for all the requirements of this specification. Prior to completion of the storage stability test, products meeting all other requirements of this specification will b
36、e listed on the qualified products list on a tentative basis. Final approval shall only be granted after the product has passed the storage stability requirements. 4.3.1 Samples. The qualification sample shall consist of six 208 litre (55- gallon) drums of hydraulic fluid for which quaTification is
37、desired. The samples shall be forwarded to the Commanding Officer, Naval Air Engineering Center, Code 912A1, Lakehurst, NJ 08733. The samples shall be plainly identified by securely attached durable tags or labels marked with the following information: SampTe for qualification inspection HYDRAULIC F

Two copies of
39、 the manufacturers test report, containing complete test data showing that material submitted for qualification conforms to the requirements of this specification, except for compatibility, compression ignition, effect on packings and other elastomeric components, storage stability and pump performa
40、nce, shall be submitted with the qualification samples. Location and identity of the plant which produced the samples tested shall al so be suppl ied.

46、ontract number. 4.4.2 Lot and batch. All hydraulic fluid manufactured as one batch shall be considered a lot and shall be numbered as such for purposes of inspection, A batch is defined as the end product of all raw materials mixed or blended in a single operation. 4.4.3 Sample for tests. A composit
47、e sample of hydraulic fluid in sufficient quantity to perform all the quality conformance tests specified in Table III shall be taken from each lot in accordance with ASTM D 4057 or ASTM D 4177. If the sample for tests fails any of the quality conformance inspection tests, the inspection lot represe
48、nted by the composite sample shall be rejected. 4.4.4 Sample for examination of filled containers. A random sample of filled containers shall be selected from each lot of fluid in accordance with MIL-STD-105, Inspectlon Level I and an Acceptable Quality Level (AQL) of 2.5 percent defective. 4.5 Test
