Abstract

A technology for the manufacture and production of reference material (CRM) of the composition of magnesium alloys of the VML20 and VMD16 grades has been developed. In FSUE «VNIIOFI» tests of CRM material were carried out in order to approve their type, as well as metrological examination. Conclusions were drawn up on checking the results of CRM testing for the composition of the indicated alloys and certificates of type approval of reference materials were issued. CRM sets of the approved type of state standard samples of high-strength magnesium alloys of VML20 and VMD16 grades have a relative error of the certified values of the mass fraction of elements in the range from 0.5 to 5% (by weight) no more than 5% rel.
