BS/EN 60335-2-3-2016 pdf download.Household and similar electrical appliances Safety Part 2-3: Particular requirements for electric irons.
The hand-held part of the iron is then placed in a sling that is constructed by tying together
the four corners of a single layer of cheesecloth. The lowest point of the sling is suspended at
a height of 900 mm above a horizontal hardwood board approximately 20 mm thick placed on
a concrete or similar hard surface.
The iron in the sling is dropped from a stationary position. The test is carried out three times, the iron being positioned so that it falls onto the board first on the right side, then on the left side and subsequently on its heel. The iron is reheated prior to each drop.
After the test, the iron shall withstand the electric strength test of 16.3, steam irons first being filled with water as specified in the instructions and allowed to rest for 10 mm on their stands
The iron shall not be damaged to such an extent that compliance with 8. 1 and 19.4 is impaired,
22 Construction
This clause of Part 1 is applicable except as follows.
22.7 Replacement:
Pressurized steam Irons and Instantaneous steam Irons shall incorporate adequate safeguards against the risk of excessive pressure.
If jets of steam or hot water are emitted through protective devices, the electrical insulation shall not be affected or the user exposed to a hazard.
Compliance is checked by inspection and by the following test.
For pressurized steam irons. the maximum pressure occurring during the test of Clause 11 with the boiler filled but without steam emission is measured. All pressure-regulating devices that operated during the test are rendered inoperative and the pressure shall not exceed three times the previously measured value. Any pressure-limiting protective device is then rendered inoperative and the pressure in the boiler is raised hydraulically to five times the pressure measured originally or twice the pressure measured with the pressure-regulating devices rendered inoperative, whichever is higher. This pressure is maintained for I mm. There shall be no leakage from the appliance. Hoses that are subjected to the pressure within the boiler when the iron is placed on its rest or during normal use of the appliance are also subjected to the hydraulic pressure test.
Pressurized steam irons in which the device regulating the steam supply is within the boiler are operated as specified in Clause 11 but with all pressure-regulating devices operating during the test of Clause 11 rendered inoperative. All vents in the sole plate are sealed and the device regulating the steam supply is opened. There shall be no leakage from the hose except at an intentionally weak place within the enclosure of the boiler. if this occurs, the test is repeated on another appliance that shall also leak in the same way.
All vents in the soleplate of instantaneous steam irons are sealed and the pressure in the water reservoir is raised hydraulically until the pressure-limiting protective device operates. The pressure shall not exceed 50 kPa. The outlet through the protective device is then sealed and the pressure is raised to 100 kPa and maintained at this value for I mm. There shall be no leakage from the appliance.
22.101 Irons shall be provided with a stand. Compliance is checked by inspection.
22.102 Steam irons shall be constructed so that there is no spillage of water or sudden jets of steam or hot water likely to expose the user to a hazard when the iron Is used in accordance with the instructions.
When removing the filling cap of boilers, the pressure shall be relieved in a controlled manner before the cap is removed completely, to avoid the emission of jets of steam or hot water in a manner likely to expose the user to a hazard.
Compliance is checked by inspection during the test of Clause 11 and by removing the filling cap at the end of the test.
22.103 The boiler of steam Irons with a separate boiler shall incorporate at least one non-
self-resetting thermal cut-out that is only accessible by means of a tool. Compliance Is checked by inspection.
22.104 Pressure-limiting protective devices that operate during the tests of 19.4 and 22.7 shall have an inlet aperture at least 5 mm in diameter or 20 mm2 In area and a width of at least 4 mm, The area of the aperture at the outlet shall not be less than that of the aperture at the inlet.
Compliance is checked by measurement.
22.105 The connection contacts of cordless irons shall be constructed so that any electrical or mechanical failure occurring in normal use will not give rise to a hazard.BS/EN 60335-2-3-2016 pdf download.
