These group standards will be included in state primary standard of complex resistance. These standards have good long time stability. It's year non stability is less than 0,0002%. Research of these standards shown that these ones have good metrologies parameters. It can be included in primary state standard after investigation of their parameter on alternative current and determination of it's frequency correction coefficients.
