TECHNICAL REQUIREMENTS 3.1 Material The flux shall be a uniformly blende
13、d mixture, primarily metallic chlorides with the addition of metallic fluorides. Other metallic salts of alkaline metals are permitted as required to assist in fluxing ability. 3.1.1 The flux, used in accordance with AMS2673, shall produce satisfactory brazed joints acceptable to purchaser. 3.2 Prop
14、erties Flux shall conform to the following requirements: 3.2.1 Flux shall be fully molten at 1030 F (554 C). The liquidus of the flux shall be 1030 F (554 C) or lower. 3.2.2 Flux shall not etch parent metal to an extent greater than indicated by the following test: 3.2.2.1 A coupon of aluminum alloy
15、 1100 or 3003, nominally 0.025 u 1 u 6 inches (0.64 u 25 u 152 mm), immersed for two minutes 0.2 minutes in a bath of dehydrated molten flux at 1120 F 10 F (604 C 6 C), shall not be reduced more than 0.001 inch (0.025 mm) in thickness. 3.2.3 Flux adhering to brazed assemblies shall be removable by e
16、ither: 1) water at 190 F (88 C) or hotter or 2) by the hot water followed by immersion for not more than 15 minutes in a 10% (approximately) solution of nitric acid to which 0.25% (approximately) hydrofluoric acid is added, at a solution temperature not higher than 100 F (38 C). 3.2.4 The flux shall
17、 not contain more than 5% by weight water as determined by the water content test in accordance with AWS A5.31. 3.2.5 Flux shall pass the fluidity test in accordance with AWS A5.31. 3.2.6 Flux shall pass the flow test in accordance with AWS A5.31. The shelf life shall be a minimum of six months from
18、 date of manufacture when stored in its original unopened container. 3.3 Quality Flux, as received by purchaser, shall be a uniformly blended mixture free from contaminants and foreign materials detrimental to usage of the flux.

19、4.1 Responsibility for Inspection The supplier of flux shall supply all samples for suppliers 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 flux conforms to
20、specified requirements. 4.2 Classification of Tests All technical requirements are preproduction tests and shall be performed at a frequency as agreed upon with the purchaser. 4.3 Sampling and Testing At least one randomly selected sample of flux from the lot selected for test; a lot shall be all fl
21、ux in an identifiable quantity processed at one time and presented for inspection at one time. 4.4 Approval Producer shall assign a product identification of letters and/or numbers, traceable to a specific set of ingredients, methods of manufacture and manufacturing controls. If it is necessary to m
22、ake any changes to the ingredients or proportions of ingredients, methods of manufacture, or to manufacturing controls, that unique name, number or series of letters and/or numbers shall be changed (see 5.1). 4.5 Reports The supplier of flux shall furnish with each shipment a report stating that the
