BS EN ISO 26423:2016

What is ISO 26423 – Coating thickness of fine ceramics about ?

ISO 26423 is one of the hosts of international standards that focus on fine ceramics.  

ISO 26423 specifies a method for the determination of the thickness of ceramic coatings by a crater-grinding method, which includes the grinding of a spherical cavity and subsequent microscopic examination of the crater. 

Note: Because of the uncertainty introduced into the measurement of crater dimensions, the test is not suitable for use where the surface roughness of the coating and/or substrate exceeds 20 % of the coating thickness. 

Who is ISO 26423 – Coating thickness of fine ceramics for ?

ISO 26423 on determining the coating thickness of fine ceramics using crater-grinding method is useful for: 

• Manufacturers of fine ceramic products  
• Designers of fine ceramic products 
• Quality control personnel 

Why should you use ISO 26423 – Coating thickness of fine ceramics ?

Coating thickness often plays a major role in the performance of coated tools and machine parts. Many different techniques have been developed for assessing the coating thickness. 

The crater-grinding method described in ISO 26423 is easy to perform and applicable to most coated systems. ISO 26423 helps you to perform the crater-grinding method accurately by providing you with the necessary details regarding apparatus requirements and step-by-step procedure to the method. 

ISO 26423 also enables you to achieve high accuracy results by providing you with formulas for the estimation of uncertainties and errors that might occur during or prior to the test procedures. 

In conclusion, the test method described in ISO 26423 helps you to calculate the coating thickness in fine ceramic components and based on that make the necessary improvements to enhance their performance.
