stability in a controlled laboratory environment and traceable to national or international primary standards”
Replace 3.1.14 with:
“
3.1.14
AC active power
is defined at any single sinusoidal frequency component of a periodic signal in a single-phase circuit as the
product of the RMS values of current and voltage and the cosine of the phase angle between them, where the
phase angle is the angle of the voltage signal vector with respect to the current signal vector
Note 1 to entry: Under sinusoidal conditions, the AC active power is the real part of the complex power.
Note 2 to entry: The AC active power of a non-sinusoidal periodic signal is the algebraic sum of the AC active power of
the sinusoidal frequency components.
Note 3 to entry: The coherent SI unit for AC active power is the watt, W.”
Replace 3.1.15 with:
“
3.1.15
active energy
electrical energy transformable into some other form of energy
Note 1 to entry: The coherent SI unit of active energy is joule, J. Another unit is watt hour. Its multiple, kilowatt hour, kWh,
is commonly used for billing consumers of electric energy and is therefore indicated on electric energy meters.
Note 2 to entry: For AC signals, the active energy is the time integral of the AC active power as defined under 3.1.14.
Note 3 to entry: For DC signals, the active energy is the time integral of the DC active power as defined under 3.1.25.

rms electric current I in the element or circuit
S = UI
Note 1 to entry: Under sinusoidal conditions, the apparent power is the modulus of the complex power S, thus S = |S|
Note 2 to entry: The coherent SI unit for apparent power is voltampere, VA.
[SOURCE: IEV 131-11-41]
3.1.27

verified by reading the energy registers through the meter’s communication ports using the communication
protocols specified by the manufacturer. ”
with
“The verification of accuracy may be performed using the relevant or established test methods, or alternatively
by reading the meter’s energy registers. The content of the meter’s energy registers may be verified by reading

the manufacturer.”
8 Modifications to Clause 9, “The effects of external influence quantities and
disturbances”
In 9.3.1.2.2, replace
“The manufacturer shall specify the number of test pulses necessary for the verification of accuracy, or an
alternative and equivalent method of verification of accuracy.”
with
“The number of test pulses necessary for the verification of accuracy shall be applied, or an alternative and
equivalent method of verification of accuracy shall be applied.”
In 9.3.2.1, add the following note to Table 16, “Voltage dips, short interruptions and voltage variations
immunity tests”:
“
NOTE 2 ΔU specifies the relative voltage reduction in Table 16. The basic standard IEC 61000-4-11 specifies the
residual voltage instead. Also, tests were modified partly compared to the basic standard based on long field experience
with TC 13 products.”
Renumber the original NOTE as “NOTE 1”.
In 9.3.2.2, add the following note to Table 17, “Voltage dips, short interruptions and voltage variations on
