Indian Standard CODE OF PRACTICE FOR LIBRARY LIGHTING
0.1 This Indian Standard was adopted by the Indian Standards Institu- tion on 5 August 1966, after the draft finalized by the Illuminating Engineering and Lifts Sectional Committee had been approved by the Electrotechnical Division Council.
0.2 The technique of interior lighting in building has developed beyond the stage involving mere provision of light. As a result of a good deal of scientific investigation it has been recognized that improvements in environmental conditions are needed to alleviate the strain on eyesight so widely prevalent. This is particularly so in a library building where all sorts of reading materials have to be read for long periods. Modern standards of interior lighting call for the provision of both quantity and quality adequate for a particular visual task so as to ensure a satisfact- ory degree of ease and comfort to the individual at work. In the design- ing of a lighting installation, provision of adequate illumination is not a guarantee of comfort. It has been found that such factors as ‘glare’ and ‘brightness .pattern’ shall receive great consideration if it is to achieve its object. From this point OF view, this code of practice has been drawn up.
