A.4.301.1 Measurement of oven temperature

Measure the temperature at the centre of the main oven and any additional oven(s) (where fitted) using

a thermocouple capable of meeting the uncertainty of measurement requirements specified in A.3.

Measure and record the centre temperature of each oven either continuously or at intervals not exceeding

1 min. At the end of the test period, calculate the mean centre temperature of each oven.

A.4.301.2 Hotplate boiling test
A.4.301.2.1 General

This test may be conducted as a separate test or as part of one of the typical test regimes detailed in

A.4.302. The hotplate boiling test may start from cold or may follow the nominal heat output test provided

that the fire has been de-ashed in accordance with A.4.3 at the termination of that test. In either case, the

---------------------- Page: 13 ----------------------
oSIST prEN 16510-2-3:2021
prEN 16510-2-3:2021 (E)

appliance is then operated for a further pre-test period in accordance with A.4.7.2 before commencing

the test period.

If the test is started from cold, the hotplate boiling pre-test period shall be preceded by an initial ignition

and pre-test period at nominal heat output in accordance with A.4.7.2.

The primary air opening to be used for the hotplate boiling test shall be as specified by the manufacturer

in the operating instructions for the appliance. If the appliance is fitted with a thermostatically controlled

primary air control, the test is carried out with the thermostatic control in operation.

A.4.301.2.2 Test utensil

The boiling test utensil shall be a steel or cast iron saucepan having the dimensions shown in

Figure A.301. The base of the saucepan shall be flat with a tolerance of 0,05 mm in the concave direction

only.
A.4.301.2.3 Pre-test period

At the end of the nominal heat output test or at the end of the initial ignition and pre-test period, de-ash

the fire if this has not already been done. Load the appliance with the calculated mass of test fuel in

accordance with A.4.2.

Where the appliance is fitted with an oven, set the primary air control as stated in the appliance operating

instructions so that a centre of oven temperature of (230 ± 30) °C is achieved. The pre-test period ends

when the centre of oven temperature has remained steady within (230 ± 30) °C for a period of not less

than 30 min.

For appliances without an oven, leave the control set for nominal heat output and allow it to operate at

this nominal heat output for a period of not less than 30 min. This ends the pre-test period.

A.4.301.2.4 Test period

Place (2 000 ± 5) g of water into the test utensil and place the lid in position. Insert a thermometer,

meeting the uncertainty of measurement requirements specified in A.3, through the hole in the centre of

the lid, so that the bottom of the thermometer bulb is positioned (10 ± 1) mm above the inside base of

the test utensil. Leave the test utensil to stand for at least 5 min. Measure the temperature of the water

and ensure that this is between 17 °C and 20 °C.

The boiling test starts 20 min after the start of the test period by placing the test utensil on the boiling

plate and ends when the temperature in the test utensil has increased by 75 K. Record the time taken for

the temperature to rise by this amount.

For cookers without an oven, maintain the control settings necessary to give the nominal heat output.

Refuel and de-ash the fire as necessary. A single hotplate boiling test shall be completed within 30 min of

the start of the test period.

For cookers with oven(s), maintain the centre of oven temperature within (230 ± 30) °C over the 120 min

boiling test period. Refuel and de-ash the fire, as necessary. A total of two boiling tests shall be carried

out, one starting 20 min into the first 60 min period and the other starting 20 min into the second 60 min

period.

Measure and record the surface temperatures of any operating knobs intended to be operated without

the use of a tool, and the temperature in any integral fuel storage container, if fitted. The temperatures

shall be measured at intervals of such duration as to ensure that the maximum temperatures achieved

are recorded.

Measure and record the temperatures of the trihedron test hearth and walls, either continuously or at

regular intervals of not more than 1 min, to ensure that the maximum temperatures achieved are

recorded.

A.4.301.3 Oven heating test
A.4.301.3.1 General

This test assesses the ability of the oven to cook satisfactorily strips of shortbread at an oven temperature

declared by the manufacturer. This test may be conducted as a separate test or as part of one of the typical

test regimes detailed in A.4.302. The test can be started from cold or may follow another test. In either

case a pre-test period is allowed to pre-condition the cooker and achieve the manufacturer's claimed

oven temperature.
A.4.301.3.2 Recipe for shortbread
For the shortbread cooking test, the following recipe is used:
— 300 g wheat flour;
— 200 g margarine taken from the refrigerator 1 h beforehand;
— 100 g caster sugar;
— 1 egg (approximately 60 g);
— 1 pinch salt.

The ingredients are mixed together in a mixer to form a paste. The mixing is stopped when a good paste

consistency is obtained. The paste is then placed in a refrigerator at a temperature between 2 °C and 10 °C

and left to stand for not less than 12 h.

The paste is removed from the refrigerator 20 min before being formed into strips (4 ± 1) mm thick and

(20 ± 2) mm width. The strips, spaced (10 ± 1) mm apart, are placed on the baking sheet parallel with the

side walls of the oven so as to fill the tray to within (25 ± 3) mm of the nearest projection from the walls

of the oven.
A.4.301.3.3 Ignition and pre-test period

Start the flue gas extraction system and adjust the applied draught so that the static pressure in the

measurement section is set to the nominal heat output test draught for the appliance as given in Figure 2,

or such other value as given in the appliance manufacturer’s installation instructions.

Load the appliance with sufficient test fuel to ensure ignition of the fuel in accordance with the appliance

manufacturer's operating instructions
