Sumary

Fine ceramics (advanced ceramics, advanced technical ceramics) - Methods of test for ceramic coatings - Determination of fracture strain

ISO 14604:2012 describes a method of measuring the fracture strain of ceramic coatings by means of uniaxial tension or compression tests coupled with acoustic emission to monitor the onset of cracking of the coating. Tensile or compressive strains can also be applied by flexure using four-point bending. Measurements can be made in favourable cases at elevated temperatures as well as at room temperature.

Advanced technical ceramics - Methods of test for ceramic coatings - Part 9 : determination of fracture strain

Le présent document décrit une méthode permettant de mesurer la déformation à la rupture des revêtements céramiques en procédant à des essais en traction et en compression uniaxiaux associés à une émission acoustique pour surveiller l'amorce de la fissuration du revêtement. Des déformations en traction ou en compression peuvent également être réalisées par flexion en utilisant un dispositif de flexion en quatre points. Les mesurages peuvent être effectués dans les cas favorables à température élevée comme à température ambiante.

ZOOM ON ... the Requirements department

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.
