IS 13252 PART 1 2010 DRIVER

The basic insulation between the primary and secondary windings is not subjected to the single fault testing required by 5. Examples are sonic acoustic , radio frequency, infra-red, ultraviolet and ionizing radiation, and high intensity visible and coherent light lasers. Three to six impulses of alternating polarity, with intervals of at least 1 s between impulses, are applied between each of the following points where relevant: NOTE 1 The test of 2. As a result, it may not pass the appropriate electric strength test if the field is substantially inhomogeneous.

T2 is the temperature of the parts measured during the test of 4. In such a case, the terminals shall be sized according to the rating of the associated supply input. NOTE Requirements regarding colours of insulation are in 2. Compliance with tlie requirements of 2.

In the case of multilayer printed boards, there shall be no delamination. The battery is then reverse charged for a single period of 7 h with that simulated failure in place.

Compliance is checked by inspection and for accessibility, where necessary, by a test with the test finger. These tests shall not result in any of the following: The failure of functional insulation is simulated only when required by 5.

The resulting physiological effects depend on the value and duration of the current and the path it takes through the body. Plugs and appliance inlets shall be so designed that reverse polarity connections are prevented if a hazard could be created by psrt connection. The battery is charged under each of the following conditions in turn.


The effect of transients from a cable distribution system is not taken into account however, see 7. After the tests of 4.

You may use these HTML tags and attributes: The pollution has no influence. Also, the abrasion resistance test of 2. Before testing a cemented joint, any winding of solvent-based enamelled wire used in the component is replaced by metal foil or by a few turns of bare wire, placed close to the cemented joint. parf

The pivoting of such terminators is considered; – short rigid conductors that remain in position when the terminal screw is loosened. Material Group lllb shall be assumed. It is permitted to leave lamps in place for this test. The downward force is applied with the complete flat surface of the test tool in contact with the EUT; the parh tool need not be in full contact with uneven surfaces for example, corrugated or curved surfaces.

Would that be sufficient or do we need the IS certificate,too? The horizontal surface consists of hardwood at least 13 mm thick, mounted on two layers of plywood each 19 mm to 20 mm thick, all supported on a concrete or equivalent non-resilient floor. For parts whose voltage, U, exceeds us kV peak or d.

Equipment with such a VDR bridging basic insulation shall be one of the following: In considering the durability of the marking, the effect of normal use shall be taken into account. NOTE 2 It is not a requirement of this standard to comply with any particular component standard for surge suppressors used in secondary circuits. The requirements of 4. NOTE 4 The tests of 2.


Breakdown of insulation between parts normally 20110 hazardous voltages and ls conductive parts. 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 the control of public authorities, in order to promote transparency and accountability in the working of every public authority, 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 iw standard is made available to promote the timely dissemination of this information in an accurate manner to the public.

Servicing instructions are normally made available only to service persons and are generally acceptable in the English language only. In any case, the thickness of the metal part at the point where a screw is threaded into 2100 shall be not less than twice the pitch of the screw thread. Moving mechanical parts in mechanical and electromechanical systems are not subjected to simulated single faults if they comply with 2.
