ASTM B551/B551M-04 pdf free.Standard Specification for Zirconium and Zirconium Alloy Strip, Sheet, and Plate.
For the purpose of determining compliance with thespecified limits for requirements of the properties listed in thefollowing table,an observed value or a calculated value shallbe rounded as indicated in accordance with the roundingmethods of Practice E 29.One longitudinal tension shall be made from each lot(see 13.1).One chemistry test for hydrogen and nitrogen contentshall be made from each lot of finished product (see 13.2).12.3 Two bend tests, one in the longitudinal and one in thetransverse direction, shall be made from each lot (see 8.2).12.4 Retests:If any sample or specimen exhibits obvious surfacecontamination or improper preparation disqualifying it as atruly representative sample, it shall be discarded and a newsample or specimen substituted.If the results of any tests of any lot do not conform tothe requirements specified, retests shall be made on additionalsheet, strip, or plate of double the original number from thesame lot,each of which shall conform to the requirementsspecified. Retesting after failure of initial retests may be doneonly with the approval of the purchaser.Conduct the tension test in accordancewith Test Methods E 8. Determine the yield strength by theoffset (0.2 %) method. Determine the tensile properties using astrain rate of 0.003 to 0.007 in./in. [mm/mm/min through theyield strength. After the yield strength has been exceeded, thecross-head speed may be increased to approximately 0.05in./in. [mm/mm]/min to failure.Conduct the chemical analysis by thestandard techniques normally used by the manufacturer.The manufacturer shall inspect the material covered bythis specification prior to shipment and,on request,shallfurnish the purchaser with certificates of test.If so specified inthe purchase order,the purchaser or his representative maywitness the testing and inspection of the material at the place ofmanufacturer.
