YY/T 0811-2010 Standard guide for extensively irradiation—Crosslinked ultra high molecular weight polyethylene fabricated forms for surgical implant applications
Basic Information
Scope
This standard applies to pure resin powders and cured high cross-linked ultra-high molecular weight polyethylene materials (products) that meet all the requirements of GB/T 19701.1 and GB/T 19701.2.
This standard does not include ultra-high molecular weight polyethylene that has only undergone gas plasma, ethylene oxide, or ionizing radiation treatment at doses less than 40 kGy, i.e., materials that have only undergone conventional sterilization treatment.
This standard only applies to UHMWPE materials that have been irradiated with high doses from gamma ray and electron beam ionizing radiation sources.
The specific relationship between the mechanical properties of the aforementioned products and their performance in the body has not been determined. Although scientists are committed to studying the relationship between polymer characteristics, polymer structure, and polymer design, this relationship has not yet been fully explained. The following mechanical tests are often used to evaluate the reproducibility of manufacturing procedures and are suitable for comparative studies of different materials.
The following warning text only applies to the test method section of Chapter 5 of this standard. This standard does not attempt to address all safety issues involved, even those related to its use. It is the responsibility of the users of this standard to establish appropriate safety and operating norms and to clarify the applicability of management restrictions before application.
