TABLE 6  Permissible Variations in Weight of Titanium Sheet
The actual weight of any one item of an ordered thickness and size in any finish is limited in overweight by the following tolerance: Any item if five sheet or less, or any item estimated to weigh 200 1b(91kg) or less, may actually weigh as much as 10% over the estimated weight. Any item of more than five sheets and estimated to weigh more than 200 1b may actually weigh as much as 71/2% over the estimated weight. There is no under tolerance in weight for titanium sheets, under tolerance being restricted by the permissible thickness variations. Only random(or mill size) sheets may be ordered on a square foot basis, and the number of square feet chipped may exceed the number ordered by as much as 5%.
8. Finish
8.1 Titanium and titanium alloy sheet, strip, and plate shall be free of injurious external and internal imperfections of a nature that will interfere with the purpose for which it is intended. Annealed material may be furnished as descaled, as sandblasted, or as ground, or both sandblasted and ground. If shipped as descaled, sandblasted, or ground, the manufacturer shall be permitted to remove minor surface imperfections by spot grinding if such grinding does not reduce the thickness of the material below the minimum permitted by the tolerance for the thickness ordered.
9. Sampling for Chemical Analysis
9.1 Samples for chemical analysis shall be representative of the material being tested. The utmost care must be used in sampling titanium for chemical analysis because of its great affinity for elements such as oxygen, nitrogen, and hydrogen. Therefore, in cutting samples for analysis, the operation should be carried out insofar as possible in a dust-free atmosphere. Chips should be collected from clean metal and tools should be clean and sharp. Samples for analysis should be stored in suitable containers.
10. methods of Chemical Analysis
10.1 The chemical analysis shall be conducted by the standard techniques normally utilized by the manufacturer and purchaser. In case of disagreement test Methods E 120 shall be used as the referee method except for carbon, oxygen, and hydrogen which are not covered in Test Methods E 120. test Method E 1447 shall be used as a referee method for hydrogen.
11. Retests
11.1 If the results of any chemical or mechanical property test lot are not in conformance with the requirements of this specification, the lot may be retested at the option of the manufacturer. The frequency of the retest will double the initial number    of tests . If the results of the retest conform to the specification, then the retest values will become the test values for certification. Only original conforming test results or the conforming retest results shall be reported to the purchaser. If the results for the retest fail to conform to the specification, the material will be rejected in accordance with Section 14.
12. Referee Test and Analysis
12.1 In the event of disagreement between the manufacturer and the purchaser on the conformance of the material to the requirements of this specification, a mutually acceptable referee shall perform the tests in question. The referee’s testing shall be used in determining conformance of the material to this specification.
13. Rounding-off procedure
13.1 For purposes of determining conformance with this specification, an observed or a calculated value shall be rounded off to the nearest“unit” in the last right-hand significant digit used in expressing the limiting value. This is in accordance with the round-off method of practice E 29.
14. Rejection
14.1 material not conforming to the specification or to authorized modifications shall be subject to rejection. Unless otherwise specified, rejected material may be returned to the manufacturer at the manufacturer’s expense, unless the purchaser receives, within three weeks of notice of rejection, other instructions for dispostion.
15. Certification
15.1 If so requested by the purchaser, the manufacturer shall supply at least one copy of his report certifying that the material supplied has been inspected and tested in accordance with the requirements of this specification and that the results of chemical analysis and mechanical tests meet the requirements of this specification for the appropriate grade.
16. Marking and Packaging
16.1
Marking: 16.1.1 Identification—Unless otherwise specified, each plate, sheet, and strip shall be marked in the respective location indicated below, with the number of this specification, heat number, manufacturer’s identification, and the nominal thickness in inches. The characters shall be not less than 3/8 in.(9.52 mm)in height, shall be applied using a suitable marking fluid, and shall be capable of being removed with a hot alkaline cleaning solution without rubbing. The marking shall have no deleterious effect on the material or its performance. The characters shall be sufficiently stable to withstand ordinary handling.
