Lcdged, braced and battered timber door shutters are frequently used in places where appearance is not the main criteria for example for temporary sheds, warehouses, stores, low cost housing, etc. This standard \\'2Sfirst published in 1971and subsequently revised in 1983. The second revision ofthis standard incorporates timber species suitable for manufacture of door shutters into four classes that isclass I to IV. The classification is based on various properties in order of pre ference. A list oftimber species which are being imported in India for manufacture of door shutters has also been included ( seeAnnex A ). Keeping in view the advantages ofmodular co-ordination, Indian Standards specify the dimensions ofcomponents in modular units. In line with this, the dimensions ofshutters were also specified in modular units. However, it was repeatedly brought to the notice ofthe committee that there was sufficient demand for sizes other than modular sizes and that the manufacturers were meeting such demands at present. This had led to a situation where shutters satisfying the other require ments ofthe standard. but not the requirements regarding the dimensions were classified as not satisfying the requirements ofthe standard. This situation also came in the way of satisfying the consumer needs for other quality requirements by a third party inspection system. Therefore, with a view to encouraging production oftimber shutters to the quality requirements specified in the standard, the Committee reviewed the relevant clauses ofthis star.dards and decided to relax the dimensional requirements in this secord revision by permitting non-modular sizes in addition to the modular sizes specified in the standard at present. However, the relaxation has been made cnly in the height and width, the thickness remaining unchanged from the present provisions. For the purpose ofdeciding whether a particular requirement of this standard is complied with. the final value, observed or calculated, expressing the result ofa test or analysis, shall be rounded off in accordance with IS 2 : 1960 'Rules for rounding off numerical values (revised)'. The number ofsignificant places retained in the rounded off value should be the same as that ofthe specified value in this standard.
