Product Details Designed to allow for motorized sieve shaking of talcum powder sieves. An enclosure shall only be designated with a stated degree of protection 6059-1 by the first characteristic numeral if it also complies with all lower degrees of protection. Ieec necessary, complementary requirements may be included in the relevant product standard, A guide for the details to be specified in relevant product standards is given in annex B, For a particular type of equipment, lec technical committee may specify different requirements provided that at least the same level of safety is ensured.
Full details are specified in the clauses indicated in the last column. Dust r and sand IEC In this standard “direct contact” is replaced by “access to hazardous parts.
The counterbalanced shield is in place for this test. The signal-circuit method should also be applied to the hazardous moving parts of high- voltage equipment. No part of the these publications may be reproduced in any form without the prior permission in writing of BIS.
BS EN 60529:1992+A2:2013
It will remain the responsibility of individual technical committees to decide on the extent and manner in which, the classification is used in their standards and to define “enclosure” as it applies to their equipment. Product Details Designed to sit on top of the specimin grate of our drip box systems. The enclosure under test is supported in its normal operating position inside the test chamber, but is not connected to a vacuum pump.
The test is continued until the whole area of the enclosure has been sprinkledTor the specified time. The tests are specified in clause The relevant product standard shall specify details such as: The maximum acceptable radius of the oscillating tube is 1 mm. It is signified with a number like IP65, IP 67 etc.
The first digit shows the extent to which the equipment is protected against particles, or to which persons are protected from enclosed hazards. Meets Requirements for Testing Standard s including but not limited to: Except for special cases to be clearly specified in the relevant product standard, no dust shall deposit where it could lead to tracking along the creepage distances.
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 Enclosures where the normal working cycle of the equipment causes reductions in air pressure within the enclosure below that of the surrounding air, for irc, due to thermal cycling effects.
For the test of first characteristic numeral 2, the jointed test finger may penetrate to its 80 mm length, but the stop face 0 50 mm x 20 mm shall not 6052-91 through the opening.
However, the tests establishinq compliance with any one of the lower degrees of protection need not ‘necessarily be carried out 6529-1 that these tests obviously would be met if applied. Annexes A and B are for information only. This standard applies to the classification of degrees of protection provided by enclosures for electrical equipment with a rated voltage not exceeding 72,5 kV. It shall not have been used for more than 20 tests.
This standard deals only with enclosures that are in all other respects suitable for their intended use as specified in the relevant product standard and which from the uec of view of materials and workmanship ensure that the claimed degrees of protection are maintained under the normal conditions of use.
Various models available offering irc sizes and either wall or ceiling mount options. This’ maximum voltage should be considered when the dielectric test voltage and the adequate clearance are determined. ISO Accredited in Scope calibration.
Conversely, an enclosure which protects equipment against ingress of particles will also protect a person from potential hazards within that enclosure, and this degree of protection is also defined as a standard. If adequate clearance is verified by a signal circuit between the probe and hazardous parts, the lamp shall not light. Base plate and specimen holder options are available.
It provides IP codes by an additional letter A, B, C or D if the actual protection of the persons against access to hazardous parts is higher than that indicated by the first characteristic numerals.
Level The first digit for solid particle protection.
The enclosure to be tested is placed at the centre point of the semicircle. Ie does not preclude the free use, in the course of implementing the standard, of necessary details, such as symbols and sizes, type or grade designations.
For any IP testing contact info itcindia. Professional in AutoCAD programming. Spherical cap of the spray nozzle is nickel-plated brass, all other metallic parts of stainless or nickel-plated steel. The suction connection shall be made to a hole specially provided for this test. Certain conventions are, however, not identical to those used in Indian Standards. An enclosure designated with second characteristic numeral 7 or 8.
Certificate of compliance included. Degrees of protection against ingress of water Indicated by the second characteristic numeral The second characteristic numeral indicates the degree of protection provided by enclosures with respect to harmful effects on the equipment due to the ingress of water. Hazardous live parts covered only with varnish or paint, or kec by oxidation or by a similar process, are covered by a metal foil electrically connected to those parts which are normally live in operation.
Verification may be made either by dielectric test or by inspection of the specified clearance dimension in air which would ensure that the tests would be satisfactory under the most unfavourable electric field configuration see IEC Also includes manual mode for flexibility. NOTE The attention of relevant technical committees is drawn to the fact that in some types of electrical equipment the maximum voltage produced internally r.
The interpretation of test results is the responsibility of the relevant technical committee. If it is impracticable to test the complete equipment, representative parts or smaller equipment having the same full-scale design details shall be tested.

The tests for the second characteristic numeral are carried out with fresh water. The texi of iEC Standard has been approved as suitable for publication as an Indian Standard without deviations. If an enclosure provides different degrees of protection for different intended mounting arrangements, the relevant degrees of protection shall be indicated by the manufacturer in the instructions related to the respective mounting arrangements.
Product Details This is an optional accessory device for the turntables. 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.
