FOREWORD
This Indian Standard wasadopted bythe Bureau ofIndian Standard afier the drafi finalized bythe Doors,Windows
and Shutters Sectional Committee had been approved bythe Civil Engineering Division Council.
GRPisanengineering plastic finding application inavariety offields ranging from aircraft androcket components
to consumer durables, Its entry into the applications in building industry in our country was made when Indian
Standards were drawn up for corrugated and plain roofing sheets and GRP Squatting pans.
Theproduct hasahigher initial cost, which ismore than offset asitisvirtually maintenance free. When subjected
to avalue engineering analysis or its life cycle cost analysis, itturns out to be very economical, too. Therefore,
with aviewtoserve the larger national objective ofprotection ofour environment andto improve thequality of life
ofthe product (when no maintenance isneeded ),this standard isevolved for GRP door shutters for internal use,
particularly for use inbathrooms/toilets and kitchens.
Composition ofthe technical committee responsible forthe formulation ofthis standard isgiven inAnnex J
For the purpose of deciding whether a particular requirement of this standard iscomplied with, the final value,
observed orcalculated, expressing theresult ofatestoranalysis, shallberounded off inaccordance with IS2:1960
‘Rules forrounding off numerical values (revised)’. Thenumber ofsignificant place retained inthe rounded off
values should be the same as that of the specified value inthis standard.
