Doors, Windows and Shutters Sectional Committee, CED II

FOREWORD This Indian Standard (Fourth Revision) was 'adopted by the Bureau of Indian Standards, after the draft finalized by the Doors. Windows and Shutters Sectional Committee had been approved by the Civil Engineering Division Council. This standard was first published in 1957 and subsequently revised in 1966, 1977 and 1991. The major modifications made in this revision are: a) Requirements that arc to met by door shutters. when tested as per relevant parts of IS 4020 (Parts I to 16) : 1998 · Door shutters--Methods of tests (third revision)' have been specified. b) 'Spot test' for determination of penetration and identification of preservatives used for treatment of timber has been included. c) Other modifications based on the prevailing practices in the country have been made. '/\ scheme of labelling environment friendly products to be known as ECO-Mark is being introduced at the instance of the Ministry of Environment and Forests (MEF), Government of India. The ECO-Mark shall be adnunistercd by the Bureau of Indian Standards (8(S) under the BIS Act, 1986 as per the Resolution No. 71 dated 21 February 1991 published in the Gazette of the Government of India. For a product to be eligible for ECOMark. it shall also carry the Standard Mark of the HIS besides meeting additional optional environment friendly requirements. ' For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960' Rules for rounding off numerical values (revised)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

5.1.3 Seasoning and Treatment

I.t This standard lays down the requirements regarding material, sizes, construction, workmanship, finish, inspection and testing of timber door shutters with timber, plywood, blockboard, veneered particle board, asbestos cement sheet, wire gauge and glass panels used in domestic buildings, offices, schools, hospitals, etc. The shutters could be single panelled or multi-panelled with or without glazing.

All timbers shall be kiln-seasoned by a suitable process conforming to IS 1141 before being planed to the required dimensions. Sap-wood of durable species and heartwood and sapwood of non-durable species shall be treated with suitable preservative (except the water soluble leachable type) as specified in IS 401. The finished components shall also be given suitable preservative treatment in places where these have been cut for joinery work. Spot test according to Annex B shall be carried out for determ ination of penetration and identification of preservatives.

t.2 This standard does not cover timber door shutters for industrial and other special buildings, such as, workshops and garages. 2 REFERENCES The standards given in Annex A contain provisions, which through references in this text, constitute provisions of this standard. At the time of publication, the editions indicated were valid.
