ISO 20343:2017规定了使用脉冲激励法测定高温下厚陶瓷单层涂层（厚度大于0.03 mm）弹性模量的试验方法。给出了试样制备程序、试验模式和速率（载荷率或位移）、数据收集和报告程序。 ISO 20343:2017主要适用于陶瓷或金属基材上的脆性陶瓷涂层。该测试方法可用于材料研究、质量控制、表征和设计数据生成目的。

ISO 20343:2017 specifies a method of test for determining the elastic modulus of thick ceramic monolayer coatings (thickness > 0,03 mm) at elevated temperatures, using the impulse excitation method. Procedures for test piece preparation, test modes and rates (load rate or displacement), data collection, and reporting procedures are given. ISO 20343:2017 applies primarily to brittle ceramic coatings on ceramic or metal substrates. This test method can be used for material research, quality control, and characterization and design data-generation purposes.
