IEC 61400-23:20 14定义了风力涡轮机叶片全尺寸结构测试以及对所获得测试结果的解释和评估的要求。该标准侧重于与叶片完整性评估相关的测试方面，供制造商和第三方调查人员使用。本标准考虑了以下试验: -静态负载测试； -疲劳试验； -疲劳试验后的静载荷试验； -确定其他叶片特性的测试。测试的目的是在可接受的概率水平上确认叶片类型的整个群体满足设计假设。

IEC 61400-23:2014 defines the requirements for full-scale structural testing of wind turbine blades and for the interpretation and evaluation of achieved test results. The standard focuses on aspects of testing related to an evaluation of the integrity of the blade, for use by manufacturers and third party investigators. The following tests are considered in this standard:
- static load tests;
- fatigue tests;
- static load tests after fatigue tests;
- tests determining other blade properties. The purpose of the tests is to confirm to an acceptable level of probability that the whole population of a blade type fulfils the design assumptions.
