TECHNICAL REQUIREMENTS: 3.1 Material: Shall consist of a solid/powder blended with additives as necess
13、ary 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 grams product to 90 mL water, conforming to ASTM D 1193, Type IV, in a 100 mL stoppered graduated cylinder, and cycling
14、 the stoppered cylinder though 15 inversions. The resultant mixture shall show no evidence of undissolved solids. Caution, heat may be generated.3.2 Properties: The product shall conform to the following requirements; tests shall be performed in accordance with specified test methods on the product
15、in maximum concentration and at maximum operating temperature recommended by the manufacturer.3.2.1 Flash Point: Shall be not lower than 100 C (212 F), determined in accordance with ASTM D 56.3.2.2 Total Immersion Corrosion: Panels, tested in accordance with ASTM F 483, shall not produce a weight ch

17、cturers recommendations, shall, to the satisfaction of the 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 free flowing and free from lumps caused by packing in an inadequate cont
18、ainer or by poor blending.4. QUALITY ASSURANCE PROVISIONS: 4.1 Responsibility for Inspection: The vendor of the product 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 confirmator
19、y testing deemed necessary to ensure that the product conforms to the specified requirements.4.2 Classification of Tests: 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 a
20、re preproduction tests and shall be performed prior to, or on, the initial shipment of the product to a purchaser, when a change in ingredients and/or processing requires reapproval as in 4.4.2, and when purchaser deems confirmatory test to be required.4.2.3 For direct U.S. Military procurement, sub
