Foreword
This standard was drafted in accordance with the rules given in GB/T
1.1-2009.
This standard replaces YY/T 0079-2006 "Implants for surgery - Metallic clip". The main differences between this standard and YY/T 0079-2006 are as
follows.
-- Modify the name of the standard, which is changed from “Implants for surgery - Metallic clip” to “Metallic clip”;
-- Revise structure type and size requirements;
-- Revise material trademark and hardness range of titanium metal clip; -- Delete tantalum metal clip and related content;
-- Add clamping performance, corrosion resistance and package sealing
requirements and test methods;
-- Add microbiological indicators requirements and test methods;
-- Improve biocompatibility requirements and test methods.
Attention is drawn to the possibility that some of the elements of this standard may be the subject of patent rights. The issuing authority shall not be held responsible for identifying any or all such patent rights.
This standard was proposed by and shall be under the jurisdiction of National Surgical Instruments Standardization Technical Committee (SAC/TC94).
