foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces YY/T 0811-2010 "Standard Requirements for High-Dose Radiation Cross-linked Ultra-High Molecular Weight Polyethylene Products for Surgical Implants".
Compared with YY/T 0811-2010, the main technical changes except editorial changes are as follows.
--- Increased the requirements for elastic modulus (see Table 1);
--- Modified the test methods for compressive modulus and thermal properties (see Table 1, Table 1 of the.2010 edition);
---Small Punch Ultimate Load, Trans Vinylidene Index (TVI) test method replaces ASTM standard with converted industry standard
(See Table 2, Table 1 of the.2010 edition);
--- Adjusted the position of electron spin resonance in the standard (see 5.2.3, Table 1 of the.2010 edition);
--- Added requirements for preclinical simulation (see 5.2.4).

High-Dose Radiation Cross-Linked Ultra-High for Surgical Implants
Molecular weight polyethylene products
1 Scope
This standard specifies the relevant provisions of high-dose radiation cross-linked (highly cross-linked) ultra-high molecular weight polyethylene (UHMWPE) products for surgical implants.
Requirements and test methods.
This standard applies to the pure resin powder required by GB/T 19701.1 or the bulk of the molding compound required by GB/T 19701.2
Amount of radiation cross-linked UHMWPE articles. This standard applies only to UHM-
WPE products.
This standard does not apply to products that have only been treated with gas plasma, ethylene oxide or ionizing radiation with a dose of less than 40kGy
UHMWPE, that is, a material that has only undergone conventional sterilization.
Note 1.The specific relationship between the mechanical properties of the above products and their in vivo properties has not been determined. Although scientists are working on polymer structure, polymer characteristics
studies on the relationship between properties and polymer design, but these relationships have not been satisfactorily explained. The following mechanical tests are commonly used to evaluate the feasibility of a manufacturing process.
Repeatability, suitable for comparative studies of different materials.
Note 2.The following warning text only applies to the test method part of Chapter 5.This standard does not attempt to address all safety issues involved, even if
are those security concerns related to its use. Establishing appropriate safety and operational practices, and clarifying the applicability of regulatory limits prior to application, is an integral part of this
Standard user's own responsibility.
