    Reference standard of the loss-angle tangent unit

    • Name – reference standard of the East-Siberian branch of FSUE «VNIIFTRI» for measurements of loss-angle tangent of solid dielectrics («DELTA 0,1-10» system)
    • Purposereference standard of the East-Siberian branch of FSUE «VNIIFTRI» for measurements of loss-angle tangent (tgd) of solid dielectrics serves to     calibrate against the loss-angle tangent in the frequency range of 0,1-10 MHz, certify (for the first time  and repeatedly) standard samples of the loss-angle tangent
    • Approval Year in accordance with the Metrological Certification – 1991
    • Technical Characteristics:

    Operating  range …………………………………………………………………… 0,1-10 MHz

    Range of loss-angle tangent for materials with dielectric permittivity

    value in the range of 2 – 80 ………………………………………………..… 5∙10-5 ÷ 10-1

    – standard deviation of measurement value of tgd, no more than

    formula_1

    – residual bias of tgd, no more than

    formula_2

    • Technical documentation: passport R52.950.009 PS

    The standard consists of:

    – Q- meter VM 560

    – AC bridge  CE 5002
