TECHNICAL REQUIREMENTS 3.1 Material Shall consist of

13、 a liquid concentrate blended with additives as necessary to meet the requirements of 3.1.1 and 3.2. 3.1.1 The product shall be readily soluble in water with moderate agitation to produce a homogeneous solution, determined by adding 25 mL product to 75 mL water, conforming to ASTM D 1193, Type IV, i

14、n a 100 mL stoppered graduated cylinder, and cycling the stoppered cylinder through ten inversions. The resultant mixture shall show no evidence of layering or precipitates. Caution, heat may be generated. 3.2 Properties The product shall conform to the following requirements; tests shall be perform

15、ed in accordance with specified test methods on the product in maximum concentration and at maximum operating temperature recommended by the manufacturer. 3.2.1 Flash Point Shall be not lower than 212 F (100 C), determined in accordance with ASTM D 56. 3.2.2 Total Immersion Corrosion Panels, tested

16、in accordance with ASTM F 483, shall not produce a weight change greater than that shown in Table 1. TABLE 1 - PERMISSIBLE WEIGHT CHANGE Test Specimen Type of Compound Maximum Weight Change mg/cm2per 24 hours AMS5045 Alkaline product Acidic product 0.8 Report loss 3.2.3 Storage Stability When stored

17、 in unopened delivery containers, the product shall, on opening after 12 months, be free from precipitates, be homogeneous, and shall meet the requirement of 3.1.1. SAE AMS1370A - 3 - 3.2.4 Performance Product, when used in accordance with manufacturers recommendations, shall, to the satisfaction of

18、 purchaser, remove oxides from ferrous components such that the surface of the components can be inspected. 3.2.5 Quality The product, as received by purchaser, shall be homogeneous and free from precipitates. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of the produc

19、t shall supply all samples for vendors tests and shall be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the product conforms to specified requirements. 4.2 Classification of Tests

20、4.2.1 Acceptance Tests Solubility (3.1.1) and flash point (3.2.1) are acceptance tests and shall be performed on each lot. 4.2.2 Preproduction Tests All technical requirements are preproduction tests and shall be performed prior to, or on, the initial shipment of the product to a purchaser, when a c

21、hange in ingredients and/ or processing requires reapproval as in 4.4.2, and when purchaser deems confirmatory test to be required. 4.3 Sampling and Testing Sufficient product shall be taken at random from each lot to perform all required tests. The number of determinations for each requirement shal

22、l be as specified in the applicable test procedure or, if not specified therein, not less than two. 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, and presented for vendors inspection at one time. 4.3.2 A
