ISO 21819-1:2018

Fine ceramics (advanced ceramics, advanced technical ceramics) - Characteristic of piezoelectric properties under high-load conditions - Part 1: Resonant-antiresonant method under high temperature conditions

This document specifies a method of measuring piezoelectric properties of piezoelectric fine ceramics and other piezoelectric devices under high-temperature conditions, where the electromechanical coupling coefficient is determined based on measurements of resonance/antiresonance frequencies using impedance analysers.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
