11、dies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizatio
12、ns, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the
13、ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of th
14、e member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 5832-14 was prepared by Technical Committee ISO/TC 150, Implants
15、for surgery, Subcommittee SC 1, Materials. ISO 5832 consists of the following parts, under the general title Implants for surgery Metallic materials: Part 1: Wrought stainless steel Part 2: Unalloyed titanium Part 3: Wrought titanium 6-aluminium 4-vanadium alloy Part 4: Cobalt-chromium-molybdenum ca

18、material has ever been shown to cause absolutely no adverse reactions in the human body. However, long-term clinical experience of the use of the material referred to in this part of ISO 5832 has shown that an acceptable level of biological response can be expected, when the material is used in appr
19、opriate applications.

20、nding test methods for, the wrought titanium 15-molybdenum 5-zirconium 3-aluminium alloy for use in the manufacture of surgical implants. This part of ISO 5832 applies to materials in bar form up to a maximum diameter of 100 mm. NOTE The mechanical properties of a sample obtained from a finished pro
21、duct made of this alloy can differ from those specified in this part of ISO 5832. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the
22、referenced document (including any amendments) applies.

23、emical composition specified in Table 1. Ingot analysis may be used for reporting all chemical requirements except hydrogen, which shall be determined after the last heat treatment and pickling procedure.

25、d condition shall be uniform and fully recrystallized single-phase beta microstructure. The grain size, determined as specified in Clause 6, shall be no coarser than grain size No. 4. at a magnification of 100 , and no alpha case or other foreign phases shall be visible. 5 Mechanical properties The
26、tensile properties of the alloy, determined as specified in Clause 6, shall be in accordance with the requirements of Table 2. Should any of the test pieces not meet specified requirements, two further test pieces representative of the same batch shall be tested in the same manner. The alloy shall b
27、e deemed to comply only if both additional test pieces meet the specified requirements. If a test piece fails outside the gauge limits, the test is invalid and a retest shall be performed. If any of the retests fails to meet the appropriate requirements, the product represented shall be deemed not t
28、o comply with this part of ISO 5832. However, the manufacturer may, if desired, subject the material to heat treatment again and resubmit it for testing in accordance with this part of ISO 5832.
