[ Superseding IS 5347 (Part 8) : 1993 ]

Reaffirmed 2023

NATIONAL FOREWORD

This Indian Standard (Part 7) which is identical with ISO 5832-7 : 2016 ‘Implants for surgery — Metallic materials — Part 7: Forgeable and cold-formed cobalt-chromium-nickel-molybdenum-iron alloy’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Orthopaedic Instruments, Implant and Accessories Sectional Committee and approval of the Medical Equipment and Hospital Planning Division Council.

This standard supersedes IS 5347 (Part 8) : 1993 ‘Requirements for orthopaedic implants: Part 8 Forgeable and cold-formed-cobalt-chromium-nickel-molybdenum-iron alloy (first revision)’. On publication of this standard, IS 5347 (Part 8) : 1993 shall be treated as withdrawn.

This Indian Standard is published in several parts. The other parts in this series are:

Part 1 Wrought stainless steel

Part 2 Unalloyed titanium

Part 3 Wrought titanium 6-aluminium 4-vanadium alloy

Part 4 Cobalt-chromium-molybdenum casting alloy

Part 5 Wrought cobalt-chromium-tungsten-nickel alloy

Part 6 Wrought cobalt-nickel-chromium-molybdenum alloy

Part 8 Wrought cobalt-nickel-chromium-molybdenum-tungsten-iron alloy

Part 9 Wrought high nitrogen stainless steel

Part 11 Wrought titanium 6-aluminium 7-niobium alloy

Part 12 Wrought cobalt-chromium-molybdenum alloy

Part 14 Wrought titanium 15-molybdenum 5-zirconium 3-aluminium alloy

The text of the ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in the Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standard, the current practice is to use a point (.) as the decimal marker.
