Independent Testing (INT)
Independent Testing Laboratories undertake complete physical, chemical, mineralogical and micro-structural analyses of various types of raw materials, cement, clinker, pozzolana, aggregate, concrete, admixtures, water, refractory, bricks, coal, lignite etc as per National and International standards.
The INT laboratories were established in 1977 on a Test House pattern and undertake testing jobs for cement, construction and allied industries within India and neighboring countries. NCB testing laboratories achieved a hallmark when NABL accredited them in the year 1997 and since then, the quality of testing services is maintained through NABL accreditation. The laboratories are BIS recognized, ISO certified and equipped with Laboratory Information Management System (LIMS) facilitating smooth and efficient operations with state-of-art instrumental facilities to carry out the tests.
