After the test cycles, the temperature rise at the terminals shall not exceed 55 K when measured in accordance with NOTE 7 Attention is drawn to the fact that solenoid operated pneumatic means may result in an unintentional synchronization. The Pt value may bo limited by using an open jec fuse, an ignitron or other suitable devices.

BS EN IEC – Switches for appliances. General requirements

In general, compliance is checked by carrying Out all the relevant tests. The diagram of the circuit in which the switch is tested Is shown in figure For PTC-S thermistors, the power dissipation of which uec 15 W far the rated zero-power resistance at an ambient temperature of 25 ‘C, the encapsulation or tubing shall comply with the flammability category FV1 or better according to lEC For the tests of electronic switches: Abrupt changes in supply voltage shall occur at zero crossings.

Characteristic Subclause fjleatis of information Common type reference C. Therefore; the circuit on the load side is always considered to be live.

Characteristic Subcl’ause Means of information Common ype reference C. The duration of the damp-heat, steady-slate test as specified in 4.

The content of the documentation shall be made available to the appliance manufacturer or end-user as appropriate in any suitable format.


Disclosure to Promote the Right To Information Whereas the Parliament of India has set out to provide a practical regime of right to information for citizens to secure access to information under isc control of public authorities, in order to promote transparency and accountability in the working of every public iiec, and whereas the attached publication of the Bureau of Indian Standards is of particular interest to the public, particularly disadvantaged communities and those engaged in the pursuit of education and knowledge, the attached public safety ifc is made available to promote the timely dissemination of this information in an accurate manner to the public.

If the additional set of specimens is not submitted at the same time, o failure of one specimen will ief The requirements of the quality control system may be met by other means, 5.

Switches for appliances – Part 1: General requirements

Attention is particularly drawn to the following: The tests should be conducted on individual switch types, which may be selected from switch families, according to annex T The number of test samples is according to table 1 of this standard They may be grouped into switch families according to annex T, and the tests may then be carried out with samples selected according to annex T.

Search the history of over billion web pages on the Internet. NOTE 1 This requirement does not apply to switching and sliding contacts, NOTE 2 This requirement does not apply to current-carrying parts which carry a current equal to or less than 20 mA. It is not economically feasible to test every switch on every application load. A switch which relies on mounting in. Compliance is checked by measurement Compliance is checked by applying axial forces wiihoul jerks equal to those specified in table 8.

NOTE For a specilic lamp load, it is recommended that he specimen be operated with loads that arc used in tHe field father than with synthetic loads, Forced cooling of the specific lamp load may be applied in ordur to ensure cold resistance for each operating cycle and shorten the test time For electronic switches, the test circuit shall be as shown in figure 19 The declared load shal, be set at rated voltage before the electronic switch is inserted into the circuit The marking for characteristics of any replaceable fuse incorporated in an electronic switch shall be placed on the fuse-holder or in the proximity of the fuse.


IEC 61058-1:2016

610581- circuit is calibrated with the following tolerances: Circuits and contacts which are not Intended for external loads are operated with the designated load. Other grouping systems may be appropriate for this purpose. As the voice of the U.

In cases wfiere basic insulation and supplementary insulation cannot be tested separately, the insulation provided is subjected to the test voltages specified or reinforced Insulation.

NOTE 3 For switches used in tropical climates, additional requirements may, be necessary. The results of the tests for switches iev indicator lamps shall be considered to apply to switches of equivalent construction without indicator lamps, or to indicator lamps of equivalent construction without he switching mechanism, 5.

Standards Subsctiption may be the perfect solution. Already Subscribed to this document. If the temperature is limited by a fuse, the following additional test is carried out: The number of operating cycles is I’d like to read this book on Kindle Don’t have a Kindle?
