8.2Weight—The shipping weight of any item of an ordered size in anyfinish condition may exceed the theoretical weight by as much as10%.
9.Workmanship,Finish,and Appearance
9.1Titanium and titanium alloy wire shall be free of injurious external and internal imperfections of a nature that will interfere with the purpose for which the wire is intended. Material may be furnished as polished,chemically cleaned, ground,or mechanically descaled,and shall have a clean, contamination-free surface.
9.1.1For specific applications,afinal sizing draw pass may be specified,with lubricants to be applied(or allowed to remain)on the wire.
10.Chemical Analysis
10.1Samples 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 met
al and tools should be clean and sharp.Hydrogen analysis shall be performed on the final cleaned wire product.
11.Methods of Chemical Analysis
11.1The chemical analysis shall normally be conducted using the ASTM standard test methods referenced in2.1.Other industry standard methods may be used where the ASTM test methods in2.1do not adequately cover the elements in the material or by agreement between the producer and purchaser. Alternate techniques are discussed in Guide E2626.
12.Retests
12.1If the results of a 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 Section15.13.Referee Test and Analysis
13.1In the event of a disagreement between the manufac-turer 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 using the ASTM standard methods in2.1.The referee’s testing shall be used in determining conformance of the material to this specification.
14.Rounding-Off Procedure
14.1For purposes of determining conformance with the specifications contained herein,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 E29.
15.Rejection
15.1Material not conforming to this 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 pur-chaser receives,within three weeks of notice of rejection,other instructions for disposition.
16.Certification
16.1The manufacturer shall supply at least one copy of the report certifying that the material supplied has been manufac-tured,inspected,sampled,and tested in accordance with the requirements of this specification and that the results of chemical analysis,tensile and other tests meet the requirements of this specification for the grade specified.The report shall include results of all chemical analysis,tensile tests,and all other tests required by the specification.
17.Packaging and Package Marking
17.1Marking—Unless otherwise specified,individual packages of straight wires or coils of wire shall have attached an appropriate tag containing the purchase order number,the specification number,the alloy,the nominal size,and the manufacturer’s lot number,or the product shall be boxed and the box marked with the same information.
17.2Packaging—Unless otherwise specified,material pur-chased under this specification may be packaged for shipment by boxing or crating with adequate protection in accordance with the manufacturer’s standard practice.
