適用范圍：The methods of measurement described in this European Standard are for use withpiezoelectric components produced from the ceramic materials described in EN 50324-1“Terms and definitions”. Methods of measurement for specific dielectric, piezoelectric andelastic coefficients are generally applicable to piezoelectric ceramics.The polycrystalline nature of ceramics, statistical fluctuations in composition and the influenceof the manufacturing process, result in specified material coefficients being typical meanvalues. These values are provided for design information only.Piezoelectric transducers can have widely differing shapes and may be employed in a range ofvibrational modes. Material parameters however, are measured on simple test-pieces (discs,rods etc. see EN 50324-1, Figure 2) using specific geometric and electrical boundaryconditions. Consequently, the results of the tests provide basic material parameters only andmust only be used as a guide to the actual properties of manufactured commercialcomponents.
