Surgical implants are made of ultra high molecular weight polyethylene
Small punch test method
1 Scope
This standard is a small disc test (thickness 0.5mm, diameter 6.4mm) small punching test method to determine the ultra-high molecular
The mechanical properties of polyethylene (UHMWPE). This standard applies to characterization of plunger extrusion or compression molding after UHMWPE surgery
The properties of the material are also suitable for the evaluation of radiation cross-linked and sterilized after the same process to manufacture the implant, but also for the recovery of the human body
(Taken from the body) of the corresponding implants were tested.
The small punch test parameters, that is, peak load, ultimate displacement, ultimate load and loss of work, can provide UHMWPE in the multi-axis
Measurement of yield strength, ultimate strength, ductility and toughness under loading conditions. Due to UHMWPE under uniaxial and multi-axis loading conditions
Mechanical properties are not the same, small punching test GB/T 19701.2 Chinese medicine grade UHMWPE uniaxial tensile test conducted a mechanical test
Test technology.
In addition to the study tools for implantation analysis, the small punch test can also be used in laboratory screening tests to evaluate the new UH-
MWPE material, such as gamma irradiation or electron beam irradiation. The test method is also applicable to accelerated aging of UHMWPE materials
(Eg, ASTMF2003), and can specify the mechanical properties of different UHMWPE samples after oxidative aging
Down grade.
Small punch test can be used for other polymers, including polymethyl methacrylate (PMMA) bone cement, polyacetal and high density polyethylene
(HDPE). However, other polymer non-UHMWPE materials, small punching test is not within the scope of this standard test method.
International units (SI) are used in this standard.
This standard does not attempt to address all the security issues involved, even those related to its use. establish
Appropriate safety and health practices, as well as the applicability of regulatory restrictions before application, are the responsibility of the user of this standard.
