FOREWORD

This Indian Standard (Part 2/See 3) (First Revision) was adopted by the Bureau of Indkm Standards, afier thedratl finalized by the Electrical Appliances Sectional Committee had been approved by the ElectrotechnicalDivision Council.

This standard was first published in 1992. This revision has been undertaken primarily to align the existingstandard with latest International Standard and also to cover requirements of steam iron, which were earliercovered under a separate standard. Safety requirements of cordless iron and travel irons have also been coveredin this standard.

This standard covers the safety requirements of electric iron. This standard does not cover the performancerequirements, which is covered under a separate standard (see IS 366).

It has been assumed in the formulation of this standard that the execution of its provisions is entrusted toappropriately qualified and experienced persons.

This standard recognizes the Indian accepted level of protection against hazards such as electrical, mechanical,thermal, fire and radiation of appliances when operated as in normal use taking into account the manufacturer’sinstructions. It also covers abnormal situations that can be expected in practice.

If the fimctions of an appliance are covered by different parts and sections of IS 302, the relevant part and sectionis applied to each function separately, as far as is reasonable. If applicable, the influence of one function on theother is taken into account.

NOTE—Throughoutthispublication,when “Part2”ismentioned, it refers to therekvant panofIS302:2007.

This standard is a product family standard dealing with the safety of appliances and takes, precedence overhorizontal and generic standards covering the same subject.

Application of this standard, as far as is reasonable, maybe considered to appliances not mentioned in Part 2,and to appliances designed on new principles.

An appliance that complies with the text of this standard will not necessarily k considered to comply with thesafety principles of the standard, if when examined and tested, it is fotqd to have other features, which impair thelevel of safety, covered by these requirements.

An appliance employixigmaterials or having forms of construction differing tlom those detailed in the requirementsof this standard may be examined and tested according to the intent of the requirements and, if found to besubstantially equivalent, may be considered to comply with the standard.

This standard is to be read in conjunction with IS 302-1 :2007 ‘Safety of household and similar electricalappliances: Part 1 General requirements (shth revision)’. For the sake of convenience, the clauses of this standardcorrespond to those of IS 302-1, instead of reproducing Ii,Illtext of each clause, clauses of IS 302-1:2007 whichare applicable (which means that relevant provisions of the clause apply) or not applicable and the sub-clauses orportion there of which are not applicable are indicated as unde~

a) In case of a clause where it is applicable, the wording used is ‘This clause of IS 302-1:2007 is applicable/not applicable’; and

b) In case of sub-clause or part thereof ‘Not applicable’.

Wherever a sub-clause of IS 302-1 :2007 is to be replaced by a new text, it has been indicated as unden

Replacement — followed by the new text.

Any addition to the existing provision of a sub-clause of IS 302-1:2007 has been indicated as undent

11 TEMPEARTURE RISE


11.2 Replacement

Irons are placed on their stands on the floor of a testcomer and away from the walls. However, the separatewater reservoir or boiler or steam irons is placed asnear to the walls as possible. Dull black paintedplywood approximately 20 mm thick is used for thetest corner.

Vented steam irons with a separate water reservoir,pressurized steam irons and instantaneous steam ironsare tested both with the water reservoir empty andfilled but without steam emission.

Irons, other than cordless irons, are also tested withthe soleplate in the horizontal position placed on threepointed metallic supports, which have a height of atleast 100 mm. Vented steam irons with a separate waterreservoir, pressurized steam irons and instantaneoussteam irons are operated with the water reservoir orboiler filed.

For appliance provided with an automatic cord reel,one-third of the total length of the cord is unreeled.The temperature rise of the cord sheath is determinedas near as possible to the hub of the reel and alsobetween the two outermost layers of the cord on thereel. However, if the cord reel is incorporated in a part,which is moved during ironing, the cord is completelyunreeled.

For cord storage devices, other than automatic cordreels, which are intended to partially accommodate thesupply cord while the appliance is in operation, 50 cmof the cord is unwound. However, for cord storagedevices on parts, which are moved during ironing, thecord is completely unwound. The temperature rise ofthe stored part of the cord is determined at the mostunfavorable place.

11.4 Addition

If the temperature rises limits are exceeded inappliances incorporating motors, transformers orelectronic circuits and the power input is lower thanthe rated power input, the test is repeated with theappliance supplied at 1.06 times rated voltage.

11.7 Replacement

Irons are operated until steady conditions areestablished.

IS 302-2-3:2007

When vented steam irons with a separate waterreservoir, pressurized steam irons and instantaneoussteam irons are tested with the iron placed on thepointed supports, steam is emitted in cycles, each cyclehaving a period of 10 s with steam emission and aperiod of 10 s with the steam emission interrupted.

11.8 Modification

Instead of the temperature rise limit of 50 K forrubber or polyvinyl chloride insulation of internalwiring, including supply cords without T-marking,60 K applies.

Addition:

During the test with the iron placed on the pointedsupports, only the temperature rises of the insulationof internal wiring and flexible cords are measured.However the temperature rise limits apply to the waterreservoir and the hose of pressurized steam irons andinstantaneous steam irons. The temperature rise of theaccessible surface of the hose shall comply with thetemperature rise limits for handles, which innormal use are held for short periods only. However,if a non-metallic hose is covered by textile material,the temperature rise of the surface of the textilematerial shall not exceed 80 K.
