ISO 15114:2014规定了确定模式II剪切载荷抗分层性的方法。使用校准的端部加载分裂（C-ELS）试验的单向纤维增强塑料复合材料的GIIC（临界能量释放率）。 它适用于碳纤维和玻璃纤维增强的热固性塑料和热塑性塑料。 范围不一定限于这些纤维和叠层，但对于具有其他类型纤维或叠层的层压板，目前没有关于样品尺寸和纤维体积含量的建议。

ISO 15114:2014 specifies a method for the determination of mode II shear load delamination resistance. G_IIC, (critical energy release rate), of unidirectional fibre-reinforced plastic composites using the calibrated end-loaded split (C-ELS) test. It is applicable to carbon-fibre and glass-fibre reinforced thermosets and thermoplastics. The scope is not necessarily limited to these fibres and lay-ups, but for laminates with other types of fibres or lay-ups, no recommendations for specimen dimensions and fibre volume content are currently available.
