IS/ IEC Degrees of protection provided by enclosures (IP Code)
This means that the full diameter of the sphere shall not pass through an opening, in the enclosure. This Indian Standard has been developed from Doc No.: If an ief rate of 40 to 60 volumes per hour is obtained the duration of the test is 2 h.
Bureau of Indian Standards BIS is a statutory institution established under the Bureau of Indian Standards Act, to promote harmonious development of the activities of standardization, marking and quality certification of goods and attending to connected matters oec the country. When the access probe is placed in the most unfavourable position sthe equipment shall be capable of withstanding the dielectric tests as specified in the relevant product standard applicable to the equipment.
Thanks and best regards. In the case where an enclosure includes sections at different voltage levels the appropriate acceptance conditions for adequate clearance shall be applied for each section.
Table 3 – Degrees of protection against water indicated by the second characteristic numeral o S 3E CD 00 I CO First characteristic numeral Degree of protection Test conditions, see Brief description Definition Non-protected – – 1 Protected against verticaliy failing water drops Vertically falling drops shall have no’ harmful effects Copyright BIS has the copyright of all its publications.
In the last two cases, the volume of air to be drawn through the enclosure under test iev be the same as for the whole enclosure in full scale. It features 3 of our devices! The first digit shows the extent to which the equipment is protected against particles, or to which persons are protected from enclosed hazards.
For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. This standard supersedes IS Additional letters are only used – if the actual protection ied access to hazardous parts is higher than that indicated by the first characteristic numeral – or if only the protection against access to hazardous parts is indicated, the first characteristic numeral being then replaced by an X.
Where appropriate, such a standard idc also specify the method of marking which is to be used when – one part of an enclosure has a different degree of protection to that of another part of the same enclosure; – the mounting position has an influence on the degree of protection; – the maximum immersion depth and time are indicated.

Search the history of over billion web pages on the Internet. S Empty enclosures If the enclosure is tested without equipment inside, detailed requirements shall be indicated by the enclosure manufacturer in his instructions for the arrangement and spacing of hazardous parts or parts which might be affected by the penetration of foreign objects or water. iev
The object of the test is to draw into the enclosure, by means of depression, a volume of air 80 times the volume of the sample enclosure tested without exceeding the extraction rate of 60 volumes per hour. International Standard IEC Unit comes with ISO compliant NIST -traceable Certificate of Calibration, one year warranty, tech support, measurement data is available at a nominal charge and cases are available.
Model P18 Spray Test Chambers. A complete integrated system! Certificate of compliance included. The talcum powder used shall be able to pass through a square-meshed sieve the nominal wire diameter of which is 50 jim and the nominal width of a gap between wires 75 jim.
However, the tests establishing compliance with any one of the lower degrees of protection need not necessarily be carried out provided that these tests obviously would be met if applied. It should be kept constant during the test. Enclosures where no pressure difference relative to the surrounding air is present. Certain conventions are, however, not identical to those used in Indian Standards.
The enclosure under test is supported in its normal operating position inside the test chamber, but is not connected to a vacuum pump.
An enclosure shall only be designated with a stated degree of protection indicated by the additional letter if the enclosure also complies with all lower degrees of protection. For undated references, the latest edition of the normative document referred to applies. Spherical cap of the spray nozzle is nickel-plated brass, all other metallic parts of stainless or nickel-plated steel. This is the standard that narrates the degree of protection dispense by the enclosures of electrical equipments.
