After these tests, neither the terminals nor the clamping means shall have worked loose, NOTE A bending tes! For switches with electronic actuating members, actuation shall be performed according to the manufacturer’s declarations. It shall still be possible to remove and to replace detachable and other external parts such as cover plates without these parts or their insulating linings being broken.
NOTE 2 Electronic switches without a mechanical switch in the supply circuit provide only electronic disconnection.
BS EN +A – Switches for appliances. General requirements
The test may be performed with test samples simulating the electrical, mechanical and thermal influences of the original indicator lamp. The foil is pushed into comers and the like by means of the standard test finger of lECbut is not pressed into openings.
Unless otherwise specified, parts connected to a SELV supply not exceeding 24 V are not considered to be live parts. If it has more than one polo, it may be called “multipolo” two-poie, three-pole, etc provided that the poles are coupled in such a manner as to Operate together 3,1.
Replaceable indicator lamps 6105-1 be replaced during the tests. Consequently, the thermal current will normally be lower than the rated current This necessitates additional tests of the terminals, contacts, etc.
The switches are intended to control electrical appliances and other equipment for household or similar purposes with a rated voltage not exceeding V and a rated current not exceeding 63 A.
Testing and measurement techniques – Section 4: The duration of the damp-heat, steady-slate test as specified in 4. Supplementary requirements for fuses for use by unskilled persons fuses mainly for household and similar applications — Sections I to IV Graphical symbols for use on equipment application Fire hazard testing — Part Testing and measurement techniques — Section 4: The intended disconnection of a ifc shall require an operation, other than a pull at the conductor, such that it can be effected manually with or without the iieip of a tool in normal use.
During the test, emission of flames or burning particles shall not occur. Clearances, creepage distances, solid insulation and coatings of rigid printed board assemblies shall comply with the relevant subclauses Testing and measurement techniques — Section 1. If there are more “ON” positions, then the verification shall be realized at the most unfavourable one. The temperature is measured 2 min after the end of the period.
Solder tsafh at ‘C. Termmals and terminattons for unprepared conductors Other tefminals ana terminations, 2DS 80 7i kec 12b Si 1 This limit applies to cabies, cords and wires complying with the relevant lEC standards, for others, it may be different. Testing and measurement techniques – Section 3: NOTE 4 The term “earthing” as used in this standard relates to “bonding.
Creepage path follows the contour of the groove but “short-circuits” the bottom of the groove by an “X” mm link. NOTE Care should be taken to ensure that tlie test current remains stable during the duration of this test. Compliance is checked by applying axial forces wiihoul jerks equal to those specified in table 8.
