SIST EN 13203-1:2015
EN 13203-1:2015 (E)
— electrical energy: ± 2 %.
The stated measurement uncertainties relate to individual measurements. For measurements that
combine a number of individual measurements, smaller uncertainties on the individual measurements
may be necessary to ensure a total uncertainty within ± 2 % under the steady state conditions.
These uncertainties correspond to two standard deviations (2σ).
4.3 Test conditions
4.3.1 General
Except where otherwise stated, the appliance shall be tested under the following conditions.
4.3.2 Test room
The appliance shall be installed in a well-ventilated, draught-free room (air speed less than 0,5 m/s).
The appliance shall be protected from direct solar radiation and radiation from heat generators.
4.3.3 Water supply
For the tests:
— domestic water pressure is the static inlet pressure under dynamic conditions measured as close as
possible to the appliance;
— inlet and outlet temperatures of the domestic water shall be measured in the centre of the flow and
as close as possible to the appliance.
The inlet temperatures shall be measured immediately upstream of the water inlet connection. Except
where otherwise stated, the outlet temperatures shall be measured immediately downstream of the

temperature measuring device, e.g. a u-tube fitted at the outlet of a tube of the same length as the
minimum length of the spout normally supplied by the manufacturer.
The hot water temperature shall be measured with a rapid response thermometer.
"Rapid response thermometer" means a measuring instrument with a response time such that 90 % of
the final temperature rise, from 15 °C to 100 °C, is obtained within about 1 s, when the sensor is
plunged into still water.
4.3.4 Steady state
Steady state operating conditions shall be regarded as established when the appliance operates for
sufficient time to reach thermal stabilization. The steady state is reached when the water temperature
at the outlet does not vary by more than ± 0,5 K.
NOTE This condition can be reached with a gas which is different from the specified test gas, provided that
the appliance is supplied with the specified test gas at least 5 min before the requirements are verified.
4.3.5 Initial adjustment of the appliance
The appliance shall be installed in accordance with the manufacturer's instructions.

5.3 Classification according to the quality of the domestic hot water produced
5.3.1 Classification procedure
The classification of appliances according to the performance in delivery of the domestic hot water
takes account of a certain number of particular performance criteria; these criteria are as follows:
— waiting time, t ;
m
— variation of the temperature according to the water rate, ΔT ;
1
— temperature fluctuation (during delivery at a constant water rate), ΔT ;
2
— temperature stabilization time in case of variation of the water rate, t ;
s
— minimum nominal water rate, D ;
m
— temperature fluctuation between successive deliveries, ΔT
3.
Depending on the test results obtained, each particular performance criterion is given a score of
between 0 and 3, called the "particular performance factor" f .
i
In addition, each criterion is associated with a weighting coefficient (a ) corresponding to a ranking of
i
importance.
An overall performance factor, F, is calculated to quantify the performance associated with the domestic
hot water delivered.
This factor F is obtained by calculating the sum of the products of the particular performance factors
multiplied by the corresponding weighting coefficients.
The particular performance factors and the weighting factors corresponding to each of the criteria
considered are given in Table 1.

5.3 Classification according to the quality of the domestic hot water produced
5.3.1 Classification procedure
The classification of appliances according to the performance in delivery of the domestic hot water takes
account of a certain number of particular performance criteria; these criteria are as follows:
— waiting time, t ;
m
— variation of the temperature according to the water rate, ΔT ;
1
— temperature fluctuation (during delivery at a constant water rate), ΔT ;
2
— temperature stabilization time in case of variation of the water rate, t ;
s
— minimum nominal water rate, D ;
m
— temperature fluctuation between successive deliveries, ΔT
3.
Depending on the test results obtained, each particular performance criterion is given a score of between 0
and 3, called the "particular performance factor" f .
i
In addition, each criterion is associated with a weighting coefficient (a) corresponding to a ranking of
i
importance.
An overall performance factor, F, is calculated to quantify the performance associated with the domestic hot
water delivered.
This factor F is obtained by calculating the sum of the products of the particular performance factors multiplied
by the corresponding weighting coefficients.
The particular performance factors and the weighting factors corresponding to each of the criteria considered
are given in Table 1.
