Electrical Resistance Transitional Standard R40114
1.1. Resistance standards R40114 are designed:
for electrical resistance values transferring from model standard in measuring DC currents through parallel-consistent switching of stages(MPEC);
1.2. Modification climatic type in accordance with GOST 15150: for areas with temperate and cold climates - YXL 4.1, but at standard R40114 working conditions:
ambient temperature (20 ± 5) ° C (for Р40115 - [20 ± 10] ° C);
relative humidity of 25 to 80%;
atmospheric pressure 84-106.7 kPa (630-800 mmHg)
2.1. Main parameters of standard R40114 are shown in Table 1.
2.2. Maximum and nominal power and voltage dissipation per stage, applied to standard, are shown in Table 1.
2.3. Standard P40114 are restorable, repairable and multifunction devices.
2.4. Acceptable basic deviation limit of resistance standard R40114 (MMEC) from nominal at primarytesting (at release from factory) is 0.02% under normal using conditions:
ambient temperature (20 ± 1) ° C;
relative humidity of 25 to 80%;
atmospheric pressure 84-106,7 kPa (630-800 mmHg);
voltage or power is not over ratedat 2.1.
2.6. Acceptable additional error of electrical resistance values transfer is less than 0.0005% under normal using conditions at p. 2.4 and amendments:
P40114 standard (ambient) temperature changes for electrical resistance values transfer time is less than 0.3 ° C, standard’s voltage isat least not over rated, shown in Table 1.
2.8. Standard P40114 additional acceptable error –caused by changes in ambient temperature between top (lower) limit of normal range temperature conditions and point adjacent of operating temperature conditions corresponding to largest change in R max, is numerically equal to maximum acceptable error, at p. 2.4 and 2.5.
2.10. Standard’s P40114 maximum acceptable additional error in percentage of its nominal value with power value dissipation from nominal to any, do not exceed maximum voltage under normal using conditions and thermal equilibrium steady state, which is numerically equal to the value of the maximum acceptable basic error at p.2.4 and 2.5.
2.12. Resistance standard’s P40114 electric insulation resistance between case and isolated dc electric circuit, is not less than 5 • 1013 Ohm in working condition, with the help of special device which reduces influence of currents leakage.
2.13. Considering maintenance and regulated operational documents, standard’s P40114 rate mean time between failure is10000 hours. Mean time between failure is set for working conditions and for voltage which is not lower than the nominal. Failure criterion of standard P40114 is discrepancy with requirements of p. 2.5.
2.15. Standard’s P40114 full average life service is 10 years.
2.16. Fixed-failure operating time for working conditions and maximum voltage (power), applied to standard is 800 hours. Failure criterion of standard P40114 is discrepancy with requirements of p. 2.5.
2.18. Content of non-ferrous and precious metals in standard P40114 is shown in Table 1.
