Hardness of ceramics – DIN EN 843-4 / ISO 14705

Normative References  



DIN EN 843-4: Advanced technical ceramics– Mechanical properties of monolithic ceramics at room temperature–Part 4: Vickers, Knoop and Rockwell superficial hardness

ISO 14705: Fine ceramics (advanced ceramics, advanced technical ceramics) - Test method for hardness of monolithic ceramics at room temperature

EN 843-4 provides three test methods to determine the hardness of ceramic materials: Vickers, Knoop and Rockwell. All three methods use an indenter to apply localized plastic deformation. The point of indentation is measured and hardness values are calculated.

Due to the brittle behavior of ceramic materials, an experienced user of the standard is needed to obtain reliable results. Due to years of experience we are proud to provide this expertise.

email problems with office 365
Dear clients & partners,

Since the end of January, we have heard from some clients who use Office 365 that they are experiencing trouble receiving our emails. Our emails seem to be classified as phishing attempts and, therefore, never reach their inboxes.

If you are also waiting for a reply, please call us at +49 8031 2313230!

We look forward to hearing from you again and hopefully re-establish full communication.

The EndoLab Team
