    FOREWORDThis Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards, after the draftfinalized by the Wood Products Sectional Committee had been approved by the Civil EngineeringDivision Council.Decorative plywood is~used in panelling work in buildings, interior lining of railway coaches, buses andships and for furniture and general interior decoration. In view of the wide field of its application,decorative plywood has to be durable, of sound construction and highest quality.This standard was first published in 1958 and was subsequently revised in 1970 and 1982 whereinmodifications in the list of species and provision of Types 1 and 2 of plywood were made. This thirdrevision of the standard is being brought out to incorporate modifications found necessary in the presentday context. This revision permits use of any species of timber for cores and backs of veneered decorativeplywood. The grade of~plywood has been limited to only Moisture Resistant (MR) and recommendeddefinite thicknesses have been included. Also the references to referred Indian Standards~have beenupdated.In the formulation of this standard due weightage has been given to international co-ordination amongthe standards and practices prevailing in different countries in addition to relating it to the practices inthe field in this country.The Committee responsible for the preparation of the standard is given at Annex C.For the-purpose of deciding whether a particular requirement of this standard is complied with, the finalvalue, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordancewith IS 2 : 1960 Rules for rounding off numerical values (reGed). The number of significant placesretained in the rounded off value should be the same as that of the specified value in this standard.
