6、 used typically for removing stains and carbon deposits from corrosion and heat resistant steel and titanium alloy thrust reverser parts removed from the aircraft, but usage is not limited to such applications. This cleaner will etch aluminum. If an aluminum-safe cleaner is required, AMS1540 should

7、be used. 1.3 Safety - Hazardous Materials While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use.

18、e, shall not show a weight change greater than 0.3 mg/cm2per 24 hours, determined in accordance with ASTM F 1111. 3.2.2 Hydrogen Embrittlement The cleaner shall be non-embrittling, determined in accordance with ASTM F 519, utilizing Type 1a, 1c, or 2a specimens, cadmium plated in accordance with MIL

19、-STD-870, Class 1, Type I. Type 1a and 1c specimens shall be loaded to 45% of the predetermined notch fracture strength, and Type 2a specimens loaded to 80% of the yield strength. The entire 2a stressed specimen, or just the notched area of the 1a and 1c stressed specimen, shall be immersed continuo

20、usly in the solution under test for 150 hours at a temperature between 68 to 86 F (20 to 30 C). 3.2.3 Flash Point Shall not be lower than 140 F (60 C), determined in accordance with ASTM D 56. 3.2.4 Solubility Cleaner shall be completely soluble in water to make a uniform solution free of gelatinous

21、 lumps, layering of ingredients, and sediment. There shall be no violent or dangerous reactions when cleaner is diluted according to manufacturers recommendations. 3.2.5 Storage Stability Cleaner shall neither show separation from exposure to heat or cold nor show an increase in turbidity greater th

22、an a control sample, determined in accordance with ASTM F 1104. 3.2.6 Biodegradability Surfactants used shall be not less than 90% biodegradable, determined in accordance with ASTM D 2667. The vendor of the cleaner shall obtain certification from surfactant manufacturer of the percent biodegradabili

23、ty of the surfactant. 3.2.7 Performance Cleaner, when used in accordance with manufacturers recommendations, shall remove carbon deposits and stains normally found on corrosion and heat resistant steel and titanium alloy thrust reverser parts. Standards for acceptance and test methods shall be as ag

24、reed upon by purchaser and vendor. 3.3 Quality The cleaner, as received by purchaser, shall be a homogeneous liquid, free from sediment, abrasives, skins, lumps, and foreign materials detrimental to usage of the cleaner. SAE INTERNATIONAL AMS1545B Page 3 of 6_ 4. QUALITY ASSURANCE PROVISIONS 4.1 Res

25、ponsibility for Inspection The vendor of cleaner shall supply all samples for vendors tests and shall be responsible for performing all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the cleaner conforms to the requireme

26、nts of this specification. 4.2 Classification of Tests 4.2.1 Acceptance Tests Tests for total immersion corrosion (3.2.1.1) and flash point (3.2.3) are acceptance tests and shall be performed on each lot. 4.2.2 Periodic Tests Tests for low-embrittling cadmium plate (3.2.1.2), hydrogen embrittlement

27、(3.2.2), solubility (3.2.4) and performance (3.2.7) are periodic tests and shall be performed at a frequency selected by the vendor unless frequency of testing is specified by purchaser. 4.2.3 Preproduction Tests Tests for all technical requirements are preproduction tests and shall be performed pri

28、or to or on the initial shipment of cleaner to a purchaser, when a change in ingredients and/or processing requires reapproval as in 4.4.2, and when purchaser deems confirmatory testing to be required. 4.2.3.1 For direct U.S. Military procurement, substantiating test data and, when requested, prepro

29、duction test material shall be submitted to the cognizant agency as directed by the procuring activity, contracting officer, or request for procurement. 4.3 Sampling and Testing Shall be in accordance with ASTM D 1568; a lot shall be all cleaner produced in a single production run from the same batc

If

33、necessary to make any change in ingredients or in manufacturing procedures, vendor shall submit for reapproval a statement of the proposed changes in ingredients and/or processing and, when requested, sample cleaner. Production cleaner made by the revised procedure shall not be shipped prior to rece

34、ipt of reapproval.

37、5.2 The vendor of cleaner shall supply a certification of compliance of biodegradability requirements (See 3.2.6). 4.6 Resampling and Retesting If any sample used in the above tests fails to meet the specified requirements, disposition of the cleaner may be based on the results of testing three addi

38、tional samples for each original nonconforming sample. Failure of any retest sample to meet the specified requirements shall be cause for rejection of the cleaner represented. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY 5.1 Packaging and Identification 5.1.1 Cleaner shall be
