40、ements typically include aluminum, vanadium, tin, chromium, molybdenum, niobium, zirconium,hafnium, bismuth, ruthenium, palladium, yttrium, copper, silicon, cobalt, tantalum, nickel, boron, manganese, and tungsten.DThe purchaser may, in the written purchase order, request analysis for specific eleme

41、nts not listed in this specification.ELower hydrogen may be obtained by negotiation with the manufacturer.B9771137. Condition7.1 Surface FinishThe surface finish shall be at thediscretion of the producer, unless specified in the purchaseorder.7.2 When specified, the ingots shall be conditioned on th

42、esurface to standards agreed upon between the manufacturer andthe purchaser.7.3 Titanium and titanium alloy ingots shall be free ofimperfections that would be deemed injurious by the standardsof acceptability agreed upon between the purchaser and themanufacturer.7.3.1 The manufacturer shall be permi

43、tted to remove minorsurface imperfections. Surface imperfections may be removedup to 1 in. (25 mm) deep from the ingot surface.Areas adjacentto the imperfection shall be blended smoothly into the ingotsurface at a slope not less than 3:1.8. Retest8.1 If any sample or specimen exhibits obvious contam

44、ina-tion, improper preparation, or flaws disqualifying it as arepresentative sample, it shall be discarded and a new sampleor specimen substituted.8.2 If the results of any test are not in conformance with therequirements of this specification, the original sample from theingot may be retested or th

45、e ingot may be re-sampled andtested.8.2.1 If the original ingot sample is retested, the frequencyof the retest will be at least double the initial number of tests.The retests will be compared to the original value to determineif the original value is an outlier in accordance with PracticeE178. If it

46、 is an outlier the retest values will be averaged andthe averaged retest values reported. If it is not an outlier all thevalues will be averaged and the averages of all of the testsbecome the test value reported. If the averaged value reportedconforms to the specification, then they become the test

47、valuesfor certification.8.2.2 The manufacturer may resample the ingot at thenon-conforming location(s) in a different area at the same axiallocation. The frequency of the resample will be at least doublethe initial number of tests. If the results of the resampleconform to the specification, then the

48、 resample values becomethe test values for certification.8.3 The manufacturer may scalp or crop the ingot to removenonconforming material then sample the remaining ingotposition(s). The ingot shall be acceptable if all results of thetests on the ingot conform to this specification.9. Sampling9.1 Sam

49、ples for chemical analyses shall be representative ofthe material being tested. The utmost care must be used insampling titanium for chemical analysis because of its greataffinity for elements such as oxygen, nitrogen, and hydrogen.Therefore in cutting samples for analysis, the operation shouldbe carried out insofar as possible in a dust-free atmosphere.Chips should be collected from clean metal and tools should beclean and sharp. Samples for analysis should be stored insuitable containers.9.2 The ingot shall be sampled at a minimum of twolocati
