ISO 21819-2:2018标准是ISO 21819系列标准的一部分，该系列标准规定了在高负荷条件下测量先进陶瓷、技术陶瓷的压电性能的测试方法。该标准是在高振动水平下使用电瞬态响应方法测量压电陶瓷材料的压电性能。该标准适用于测量压电陶瓷材料在高负荷条件下的压电性能，以评估其在实际应用中的可靠性和稳定性。

该标准要求使用电瞬态响应方法测量压电陶瓷材料的压电性能。该方法是通过在陶瓷材料上施加电压脉冲，然后测量其响应电压来测量其压电性能。在测试过程中，需要将陶瓷材料暴露在高振动水平下，以模拟实际应用中的工作条件。该标准还规定了测试过程中的其他参数，如测试频率、测试温度等。

该标准的实施可以帮助制造商评估其产品在高负荷条件下的性能，并确定其在实际应用中的可靠性和稳定性。此外，该标准还可以帮助用户选择最适合其应用的陶瓷材料。
