THE FIRST STAGE OF DEVELOPING NEW TRANSFER STANDARD IN MASS METROLOGY

The necessity of making a new transfer standard was proposed to disseminate of mass scale during or after establishing new definition of kilogram unit. It is worthy to find new material or perfect surface characterization of mass transfer standard. It should be confirmed whether a material is suitable to use as a standard after much chemical or mechanical analysis of its surface. In this presentation, we would like to present the first plan for development project of new transfer standard materials.
