What National Test House does

National Test House (NTH) is a Government of India scientific testing and calibration laboratory, established in 1912 in Calcutta (now Kolkata) under the Railway Board and currently operating under the Ministry of Consumer Affairs, Food & Public Distribution. It is described as India's largest multi-location, multidisciplinary industrial central-government testing laboratory, offering testing, calibration, and quality-evaluation services across seven regional branches (Kolkata, Mumbai, Chennai, Ghaziabad, Jaipur, Guwahati) and one satellite center in Varanasi, with Bangalore identified as a planned next node. NTH serves manufacturing industries, central and state government departments, public sector undertakings (PSUs), small-scale industries, the welding industry, and the emerging drone industry, with named customers including AAI, BHEL, Indian Oil, Coal India, DMRC, NABARD, FCI, Topcem Cements, Star Cement, Adani Group, Aditya Birla Group, Jindal Group, Saint Gobain, and HCC. NTH Ghaziabad additionally serves as India's only government drone testing and certification facility.

NTH's core technology comprises multi-disciplinary laboratories spanning Chemical and Microbiological testing (with instrumentation including GC-MS, Ion Chromatography, HPLC, ICP-MS, and Atomic Absorption Spectroscopy), Electrical testing (including lighting, conductors, cables, batteries, appliances, and high-voltage testing), Mechanical testing (Universal Testing Machines up to 2000kN), Civil Engineering testing, Non-Destructive Testing (radiography, ultrasonography, magnetic particle, dye penetration, failure analysis, and welding tests), Rubber/Plastics/Paper/Textile (RPPT) testing, and Electro-Technical and Thermal calibration with SI-unit traceability. All laboratories are NABL accredited under ISO/IEC 17025:2017 and BIS-recognized. The Laboratory Information Management System (MIS) portal at mis.nth.gov.in and the E-Samadhan mobile app, both launched in 2022, provide digital channels for online test-request submission, payment processing, and tamper-proof e-signed certificate issuance, supporting bulk payments of up to 25 test requests per transaction. NTH also operates statutory welder-certification authority under the Indian Boiler Regulations Act 1950.

NTH's revenue model is a hybrid of transaction-fee testing and calibration services, professional-services training programs, and Government of India budgetary support under its parent Ministry. Pricing is structured as pay-as-you-go unit pricing per test parameter, with three visible tiers: Standard Indian Standards Testing (INR 250 to INR 100,000), RDSO/Railway Specification Testing (INR 9,000 to INR 120,000), and Custom/NABL Testing (INR 625 to INR 480,000), plus selective tests reaching INR 1,000,000. Payment is accepted via Net Banking, UPI, Credit/Debit Card, the Bharatkosh government portal, and Demand Draft. The GTM motion is direct-to-customer via regional offices and the MIS portal, serving domestic Indian industry exclusively; revenue is not publicly disclosed. Leadership is led by Director General Dr. Alok Kumar Srivastava, with regional Directors heading each of the seven branches.
