However, long-term clinical experience of the use of the material referred to in t
41、his part of ISO 5832 has shown that an acceptable level of biological response can be expected, when the material is used in appropriate applications.1 ScopeThis part of ISO 5832 specifies the characteristics of, and corresponding test methods for, the wrought titanium alloy known astitanium 6-alumi
42、nium 4-vanadium alloy(Ti 6-Al 4-V alloy) for use in the manufacture of surgical implants.NOTE 1 The mechanical properties of a sample obtained from a finished product made of this alloy may not necessarily comply with the specifications given in this part of ISO 5832.2 Normative referencesThe follow
43、ing standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 5832. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 5832 are encouraged to inv
44、estigate the possibility of applying the most recent editions of the standards indicated below.

48、ce with clause 6, shall comply with the values specified in Table 2.Should any of the test pieces not meet the specified requirements, or should they break outside the gauge limits, two further test pieces representative of the same batch shall be tested in the same manner. The alloy shall be deemed to comply only if both additional test pieces meet the specified requirements.NOTE 3 However, the manufacturer may re-heat-treat the material and resubmit it for testing in accordance with this part of ISO 5832. In this case, all parts should be heat-treated in the same fashion.5.2 BendingTitaniu
