TECHNICAL REQUIREMENTS 3.1
13、Material The flux shall be a uniformly blended 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 conjunction with aluminum brazing alloys in accordance
14、 with AMS 2673, shall produce satisfactory brazed joints acceptable to purchaser. 3.2 Properties Flux shall conform to the following requirements: 3.2.1 On heating or cooling, 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 no
15、t etch parent metal to an extent greater than indicated by the following test: 3.2.2.1 A coupon of aluminum alloy 1100 or 3003, nominally 0.025 1 6 inches (0.64 25 152 mm), immersed for two minutes 0.2 in a bath of dehydrated molten flux at 1120 F 10 (604 C 6) shall not be reduced more than 0.001 in
16、ch (0.025 mm) in thickness. 3.2.3 Flux adhering to brazed assemblies shall be removable by either: 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% (approx) solution of nitric acid to which 0.25% (approx) hydrofluoric acid is added
17、, at a solution temperature not higher than 100 F (38 C). 3.2.4 The flux shall 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 a
18、ccordance with AWS A5.31. The shelf life shall be a minimum of six months from date of manufacture when stored in its original unopened container.

19、AMS 3415D - 3 - 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. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The supplier of flux shall supply all samples for supplier
20、s 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 specified requirements. 4.2 Classification of Tests All technical requirements are preproduc
21、tion 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 flux in an identifiable quantity processed at one time and presented for inspection at one tim
22、e. 4.4 Approval Supplier shall assign to the product an identification of letters and/or numbers, traceable to a specific set of ingredients, methods of manufacture and manufacturing controls. If it is necessary to make any changes to the ingredients or proportions of ingredients, methods of manufac
23、ture, 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 flux conforms to the technical requirements. This report shall include the purchase
24、 order number, lot number, AMS 3415D, date of manufacture, and quantity. 4.5.1 A material safety data sheet conforming to 29 CFR 1910.1200, or equivalent, shall be supplied to each purchaser prior to, or concurrent with, the report of preproduction test results or, if preproduction testing be waived
25、 by purchaser, concurrent with the first shipment of flux for production use. Each request for modification of flux formulation shall be accompanied by a revised data sheet for the proposed formulation. 4.6 Resampling and Retesting If any sample used in the above tests fails to meet the specified re
26、quirements, disposition of the flux may be based on 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 flux represented. Results of all tests shall be reported. Co
