The source reference :- Chakrabarti, D.,1997: Indian Anthropometric Dimensions for Ergonomic design Practice, NID, Ahmedabad, India
	Key to follow the datasheet. The below key structure showing landmarks, definitions and data table structure is used in all the data sheets incorporated in this presentation under different experiment heads.
	The compiled data (with relevant descriptions of anthropometric terminology and illustrative descriptions with the respective measurement landmarks) are presented herewith as INDIAN ANTHROPOMETRIC DIMENSIONS separately for Males, Females and Combined (males and females both considering a single study	population) forms in the sequence of illustrative measurement land marks, brief of dimensions! measurements and the data table. Dimensional reference numbers as 'R. No.' shown in illustrations and referred both in definitions and in data tables simultaneously. All dimensions (except body weight in Kg) are in millimeters (mm).
