ISO 16402 骨科用丙烯酸树脂水泥的弯曲试验
在植入过程中，用骨水泥填补在种植体与骨之间的空间，因此骨水泥的长期力学稳定性对植入的成功至关重要。通过进行静态和循环加载，可以得到这些骨水泥的力学性能
ISO 16402“外科植入物-丙烯酸树脂水泥-骨科用丙烯酸树脂水泥的弯曲试验”提供了在实验室情况下进行弯曲试验的标准，包括准静态弯曲试验和疲劳弯曲试验
在保持37° C的林格氏液中采用一个微型4点弯曲夹具。在准静态弯曲试验完成后，进行疲劳试验，得到应力-循环次数（S/N）曲线。
我们建议采用ElectroPuls全电子动态试验机或8870电液伺服疲劳试验系统来对这些骨水泥进行准静态或循环加载试验。
我们建议您仔细阅读标准更详细地理解其要求。
