QUALITY ASSURANCE PROVISIONS: 4.1Responsibility for Inspection: T
14、he vendor of the product shall supply all samples and shall be responsible for performing all required tests. Results of such tests shall be reported to the purchaser as required by 4.6. Purchaser reserves the right to perform such confirmatory testing as he deems necessary to ensure that the produc
15、t conforms to the requirements of this specification, 4.2Classification of Tests: 4.2.1Acceptance Tests: Tests to determine conformance to requirements for ASTM color (3.2. l), flash point (3.2.2), specific gravity (3.2.6), and viscosity (3.2.7) are classified as acceptance tests and shall be perfor
16、med on each lot. -,-,- - 3 - AMS 3158A 4.2.2 Qualification Tests: Tests to determine conformance to all technical requirements of this specification are classified as qualification tests and shall be performed on the initial shipment of a product to a purchaser, when a change in material or processi
17、ng requires reapproval as in 4.4.2, and when purchaser deems confirmatory testing to be required. 4.2.2.1For direct U.S. Military procurement, substantiating test data and, when requested, preproduction test material shall be submitted to the cognizant qualification agency as directed by the procuri
18、ng activity, the contracting officer, or the request for procurement. 4.3 Sampling: Each lot of fluorescent penetrant solution shall be sampled to provide sufficient material to perform required testing. The number of specimens for each test shall be as specified in the applicable test procedure or,
19、 if not specified therein, not less than three. 4.3.1 A lot shall be all product produced in a single production run from the same batches of raw materials under the same fixed conditions, or all material subjected to the same unit chemical or physical process intended to make the final product homo
20、geneous, and submitted for vendors inspection at one time. 4.4 Approval: 4.4.1Sample solution shall be approved by purchaser before solution for production use is supplied, unless such approval be waived.Results of tests on production solution shall be essentially equivalent to those on the approved
21、 sample. 4.4.2Vendor shall use ingredients, manufacturing procedures and processes, and methods of inspection on production solution which are essentially the same as those used on the approved sample solution. If any change is necessary in ingredients, in type of equipment for processing, or in man

26、solution and insert a clean cuvette filled with water, then cover.Again depress shutter and adjust meter to read zero with “Blk“ controls. Remove water- filled cuvette, reinsert cuvette of approved reference solution, and cover. Again depress shutter and set needle at 50, using “Std“ control. Remove
27、 cuvette of approved reference solution, insert cuvette of sample solution, cover, and depress shutter to read sample solution value.
