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.
2.5. Acceptable basic deviation limit of resistance standard R40114 (MMEC) from nominal at primarytesting (at release from factory) is 0.02% under normal using conditions at p. 2.4.
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.
2.7. Resistance standard’s P40114 (MPEC) acceptable resistance change (instability)  does not exceed values in p.2.4 and  2.5. after a year from the date of first attestation.
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.
2.9. 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 capacity 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.
2.10. 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.
