Household and similar food roasting appliance

Toaster, waffle iron and sandwich grill

5.2 Safety

The product safety as covered by this standard shall comply with the

requirements of GB 4706.14.

5.3 In-appliance materials

5.3.1 The in-appliance materials in contact with food shall comply with the

relevant national food hygiene standards:

a) Aluminum products shall comply with the requirements of GB 11333;

b) Stainless-steel products shall comply with the requirements of GB 9684;

c) The ceramic products shall comply with the requirements of GB 13121;

d) Coatings and products of other materials shall comply with the

corresponding national standards, industry standards or be certified by the

relevant institutions through inspections to prove compliance with the

national food hygiene requirements;

5.3.2 After the coating on the sprayed surface is subjected to the cross-cut test,

the number of coating-off grids shall not exceed 5%.

5.4 Timing control performance

For the appliances with timing function, the timing deviation of the timer shall

not exceed ±5%.

5.5 Power consumption at standby mode and off mode

The power consumption at standby mode and off mode shall be not more than

0.5 W. For the appliances which have the information or state display (including

clock) function in the standby mode, the power consumption at standby mode

shall be not more than 1 W.

5.6 Roasting performance

When the food is subjected to a roasting test, if the browning is between 4 and

5.7 Roasting time

Squeeze the tape and the coating to achieve maximum bond. Pull one end of

the tape up quickly along the perpendicular direction. Along two different

directions in the grid area, respectively repeat the above steps 5 times for each,

use new tape for each repeated operation.

6.4 Timing control performance

Turn the appliance to the rated voltage, adjust the timer to the maximum timing,

measure the time when it automatically cuts off the power.

6.5 Power consumption at standby mode and off mode

The accuracy of the power meter and electric energy meter used in this test

shall not be less than 0.01 W.

Before the test, it shall place the appliance in an environment which has a

temperature of 15 °C ~ 25 °C and a humidity of 45% ~ 75% for at least 6 h, so

that the overall temperature of the appliance is at (20 ± 5) °C.

Note: It may use the forced cooling method to assist in reducing the temperature

of the appliance, in which case the appliance's placement time may be reduced.

The appliance is in an unloaded state during the test and is in the state of

maximum power consumption in standby mode or off mode. The test is carried

out in accordance with the methods of 6.5.1 or 6.5.2.

6.5.1 Short-term power measurement method

This test method is only applicable to the selected mode and power stable

conditions. If the measured change of power within 5 min is less than 5%, the

power is considered to be stable, in which case it may directly read the power

value as displayed by the instrument.

Connect the appliance to the measuring instrument. Select the mode to be

measured. After the appliance has passed at least 5 minutes to stabilize the

power, use the measuring instrument to measure the power consumption, the

time shall not be less than 5 min. The change of power value during the

measurement is less than 5% (obtained from the observed maximum power

value), the power is considered to be stable. Directly record the power value at

the end of 5 min from the measuring instrument.

6.5.2 Average power method

This test method is suitable for the conditions where the selected mode or the

measured power is unstable. However, this method is also applicable to all

cases where the mode is stable. This method uses the average power reading

or cumulative energy for the user's selected time period.

sandwiches shall meet the requirements of 5.8.

6.9 Temperature control performance

6.9.1 Place the browning adjustment device at the highest position. Let the

appliance run at no load. Use the thermocouple to measure the temperature of

the temperature controller at the 3rd, 4th, 5th ON and OFF operations at the

center points of the upper and lower working surfaces of the appliance.

Calculate the average temperature for each ON and OFF operation.

6.9.2 In the operating temperature range of the waffle iron and sandwich grill,

let the appliance run at no load. Use the thermocouple to measure the

temperature of the temperature controller at the 3rd, 4th, 5th ON and OFF

operations at the center points of the upper and lower working surfaces of the

appliance. The deviation of action temperatures is the difference between each

OFF temperature and nominal temperature value (if any). The amplitude of

change of ON-OFF action temperatures is the maximum temperature of the

absolute value of the difference between each ON temperature and OFF

temperature. The deviation of action temperatures and the amplitude of change

of ON-OFF action temperature shall comply with the provisions of 5.9.2.

6.10 Durability of hinge

The durability of the two grille hinges of the waffle iron and the sandwich grill

shall be subjected to the open-close test at the frequency of 8 times/min ~ 10

times/min. The appliance is opened to the maximum angle during the test. Carry

out 5000 times of tests.

6.11 Bread rack's operating force

Put a standard bread slice in the roasting cavity. Open the bread rack's lock.

Use a dynamometer to hook the handle of the bread rack as shown in Figure 2,

to measure the maximum force required for the operation.

6.12 Service life of toaster

Connect the toaster to the rated voltage. Place the browning adjustment device

to the highest position. Press down the button. After 30 s after the first popup,

press down the button again. After the second popup, first place it for 5 min,

then col the appliance to room temperature, which forms 1 cycle. Carry out

7.1 Classification of inspections

Inspection is divided into exit-factory inspection and type inspection.
