BS EN 725-3:2007

This standard BS EN 725-3:2007 Advanced technical ceramics. Methods of test for ceramic powders is classified in these ICS categories:

• 81.060.30 Advanced ceramics

This part of EN 725 describes a method for the determination of the oxygen content of non-oxide powders used for advanced technical ceramics, using an inert carrier gas thermal extraction method. The method described is suitable for oxygen contents of less than 3 %. NOTE An indication of the limits of determination is usually given by the manufacturers of the gas analysis apparatus used. However, for a specific measurement procedure, such limits can be determined by experiments conducted by the user.
