Addition:
Appliances that are manually filled shall have a level mark or other means to indicate when they are filled to their rated capacity, unless they cannot be filled beyond this capacity. This indication shall be visible when the appliance is being filled.
If the temperature of the water vapour exceeds 60 C, the appliance shall be marked with the substance of the following:
CAUTION: Hot water vapour
7.12 Addition:
The instructions shall include details regarding filling, cleaning and descaling.
The instructions shall state the substance of the following:
— care should be taken when using the appliance due to the emission of hot water vapour;
— unplug the appliance during filling and cleaning.
The instructions for electrode-type appliances shall include the substance of the following:
— the composition and quantity of solution to be used and advice not to use an excessive amount of salt;
— the appliance is not to be operated from a d.c. supply.
7.12.1 Addition:
The installation instructions for appliances intended to be connected to the water mains shall state the maximum permissible water pressure in pascals.
8 Protection against access to live parts
This clause of Part 1 is applicable.
9 Starting of motor-operated appliances
This clause of Part I is not applicable.
10 Power input and current
This clause of Part 1 is applicable except as follows.
10.1 Modification:
NOTE 101 For electrode-type appliances, the negative deviation is not limited.
11 Heating
This clause of Part 1 is applicable except as follows.
11.4 Modification:
Electrode-type appliances are supplied at 1,06 times rated voltage.
Addition:
If the temperature rise limits are exceeded in appliances incorporating motors, transformers or electronic circuits, and the power input is lower than the rated power input, the test is repeated with the appliance supplied at 1,06 times rated voltage.
11.6 Replacement:
Combined appliances are operated as heating appliances.
11.7 Replacement:
Appliances are operated until steady conditions are established.
11.8 Addition:
The temperature rise limits of motors, transformers and components of electronic circuits, including parts directly influenced by them, may be exceeded when the appliance is operated at 1,15 times rated power Input.
12 Void
13 Leakage current and electric strength at operating temperature
This clause of Part 1 is applicable except as follows.
13.1 Modification:
Electrode-type appliances are supplied at 1,06 times rated voltage.
13.2 Addition:
For electrode-type appliances, the leakage current is measured between a metallic mesh placed in the water vapour, 10 mm from the outlet, and accessible metal parts.
The leakage current shall not exceed 0,25 mA.
NOTE 101 Accessible metal parts include the metal foil,
14 Transient overvoltages
This clause of Part I is applicable.
15 Moisture resistance
This clause of Part 1 is applicable except as follows.
15.2 Addition:
In case of doubt, the spillage test is carried out with the appliance deviating from the normal position of use by an angle not exceeding 5°.
Appliances intended to be connected to the water mains are operated until the maximum water level is reached. The inlet valve is held open and the filling continued for 15 mm after the first evidence of overflow or until the in flow stops automatically.
16 Leakage current and electric strength
This clause of Part 1 is applicable.
17 Overload protection of transformers and associated circuits This clause of Part 1 is applicable.
18 Endurance
This clause of Part 1 is not appiicable,
19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.2 Addition:
The container of electrode-type appliances is filled with a saturated solution of NaCI at 20 °C t 5 °C. the appliance being supplied at rated voltage.
NOTE 101 A solution is saturated when no more salt can be dissolved.
19.3 Addition:
The test is not applicable to electrode-type appliances.
19.4 Modification:
Appliances are only filled with sufficient water to cover the heating elements.
Fans are switched off.
20 Stability and mechanical hazards
This clause of Part 1 is applicable.
