The National Test House[ NTH], formerly known as the Government Test House, was set up long ago by the then Railway Board in Calcutta in 1912 to meet the requirements of the Indian Railways through import substitution. The Indian Industrial Commission recommended for an Indian Stores Department during 1916-1918, and the same was formed that absorbed NTH for long-term testing of the general stores required by government departments including the Department of Defence. In 1934, the Industrial Intelligence and Research Bureau was later re-designated as the Industrial Research Bureau, the genesis of contemporary CSIR, created by the Government of India and housed and nurtured in NTH to conduct research on issues directly related to indigenous raw material growth.
