ISO 4884 is an international standard on hard metals that discusses the best procedures and specifications required for sampling and testing hard metals. ISO 4884 specifies procedures for the sampling and testing of powder mixtures for the manufacture of hard metals, using sintered test pieces. It also covers the preparation of test pieces. 

Who is ISO 4884- Hardmetals for?  

ISO 4884 on hard metals is relevant to: 

• Manufacturer of hard metals 
• Laboratories and Research centers  

Why should you use ISO 4884- Hardmetals?
