Céramiques techniques — Méthode de mesurage de la contrainte piézoélectrique à champ électrique élevé

ISO 17859:2015 specifies the measurement method of piezoelectric strain at high electric field for high power piezoelectric devices. ISO 17859:2015 is intended to be used to determine the piezoelectric strain coefficient of the materials by measuring strain vs. electric field:

? applied electric field: 0 to 2 MV/m;

? frequency of electric field: 0,1 to 1 Hz.
