QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The ven
22、dor of the cleaner shall supply all samples for vendors tests and shall be responsible for the performance of all required tests. Results of such tests shall be reported to the purchaser as required by 4.6. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessa
23、ry to ensure that the cleaner conforms to specified requirements. 4.2 Classification of Tests Tests to determine conformance to all technical requirements of this specification are classified as preproduction tests and shall be performed prior to or on the initial shipment of cleaner to a purchaser,
24、 when a change in material, processing, or both requires reapproval as in 4.4.2, and when purchaser deems confirmatory testing to be required. 4.2.1 For direct U.S. Military procurement, substantiating test data and, when requested, preproduction test material shall be submitted to the cognizant age
25、ncy as directed by the procuring activity, the contracting officer, or the request for procurement. 4.3 Sampling Shall be in accordance with ASTM D 1568.

31、 to hold the specimen and the cotton swab. 4.5.1.1.3 Rinse the specimen several times in a beaker of clean acetone. 4.5.1.1.4 Shake off excess acetone and dry in a vacuum desiccator or in an oven at 35 C 3 (100 F 5) for not less than 15 minutes. 4.5.1.1.5 Weigh the test specimen to the nearest 0.1 m
32、illigram (W1). 4.5.1.2 Procedure 4.5.1.2.1 Make up 750 mL 10 of a solution of cleaner in a 1-L corrosion-resistant steel beaker. The solution concentration shall be the highest recommended by the manufacturer. ASTM D 1193, Type IV, reagent water shall be used to prepare the solution. 4.5.1.2.2 Maint
33、ain the temperature of the solution at the maximum recommended by the manufacturer for the duration of the test. 4.5.1.2.3 Suspend the specimen in the center of the beaker so that it is completely immersed and cannot come into contact with the beaker during the test. 4.5.1.2.4 Connect the beaker and
34、 specimen in a direct current electrical circuit as shown in Figure 1 using rheostat R to control the flow of current. FIGURE 1 SAE AMS1547A - 5 - 4.5.1.2.5 Using rheostat R, increase the current registered by ammeter A to 3.00 A 0.25. Allow current to flow for not less than 15 minutes. 4.5.1.2.6 Af
35、ter 15 minutes 0.2 shut off the current and remove the test specimen from the circuit. Wash the specimen in cold ASTM D 1193, Type IV, water followed by rinsing in acetone. 4.5.1.2.7 Dry and weigh the specimen as detailed in 4.5.1.1.4 and 4.5.1.1.5 (W2). 4.5.1.2.8 Calculate weight variance from the

Each request for modification of cleaner formulation shall be accompanied by a revised data sheet for the proposed formul
39、ation. 4.6.1.2 A bulletin describing the cleaner and detailed instructions for its use shall be provided by the cleaner manufacturer. The bulletin shall also include mixing instructions, material compatibility, properties, control/analysis procedures, and safety practices including precautions for h
40、azardous ingredients. 4.6.2 Unless waived by purchaser, the vendor of cleaner shall furnish with each subsequent shipment a report stating that the cleaner is of essentially the same formulation as the approved sample cleaner and conforms to the technical requirements of this specification. If resul
41、ts of the storage stability test were not included in the report on the initial shipment of cleaner, results of that test shall be included in the report on the first shipment following completion of that test. This report shall include the purchase order number, lot number, AMS1547A, manufacturers
42、identification, and quantity. If cleaner from more than one lot is supplied in one shipment, a report shall be supplied for each lot in the shipment. 4.7 Resampling and Retesting If any sample used in the above tests fails to meet the specified requirements, disposition of the cleaner may be based o
43、n the results of testing three additional samples for each original nonconforming sample. Failure of any retest sample to meet the specified requirements shall be cause for rejection of the cleaner represented and no additional testing shall be permitted. Results of all tests shall be reported. 5. P
