Testing labs in Udaipur 313 003

Yadav Measurements Private Limited (YMPL), headquartered in Udaipur, Rajasthan, India, is the country's leading independent, internationally accredited testing and calibration laboratory. Originally established in 1996 as Yadav Metrology Lab and incorporated as a private limited company in July 2003 (CIN: U31909RJ2003PTC018450), YMPL operates from its permanent facility at 373-375 RIICO Bhama Shah Industrial Area, Kaladwas, Udaipur, Rajasthan 313003 and deploys mobile on-site services nationwide. The laboratory supports original equipment manufacturers (OEMs), utilities, meter manufacturers, and regulatory bodies seeking compliance with Indian and international standards, serving customers across the power, gas, healthcare, IT and telecommunications, automotive, lighting, and industrial automation sectors. YMPL's foundational expertise lies in the power and energy sector, where it functions as India's premier independent type-testing laboratory for static electricity meters and power-monitoring equipment. The laboratory has tested more than five million meters to date, offering full and partial type testing of single- and three-phase static energy meters in accordance with IEC 62052-11, IEC 62052-21, IEC 62052-22, IEC 62052-23, IEC 61036, IEC 60687, IEC 61268, Indian standards IS 13779 and IS 14697, Australian standards AS 1284.5 and AS 1284.9, NSC M6, and CBIP Report-88. Type testing is also performed on instrument transformers — current transformers (CT) and potential transformers (PT) — per IS 2705 and IS 3156, and on electrical measuring transducers per IEC 60688 and IS 12784. A signature YMPL capability is its Mobile Laboratory, MobiLAB — a deployable NABL-accredited facility that brings precision calibration directly to live high-voltage substations across India. The current MobiLAB extends on-site calibration of instrument transformers up to 220 kV, allowing utilities to verify in-service transformers without decommissioning them, reducing outage risk and operational costs during India's rapid grid modernisation. YMPL additionally facilitates European MID (Measuring Instruments Directive) certification for smart meters through a formal collaboration with Istituto Giordano (IG), Italy, and SASTEK, Turkey, enabling Indian manufacturers to achieve regulatory market access across the European Union. Beyond power metering, YMPL offers specialist testing across several adjacent sectors. In the gas sector, the laboratory performs type testing and calibration of diaphragm and ultrasonic domestic gas meters to BS EN 1359, BS EN 14236, EN 16314, OIML R137-1&2, and IEC 60068-2, helping gas utilities avoid the significant financial losses associated with inaccurate measurement in transmission and distribution networks. In healthcare, YMPL evaluates medical devices — ranging from pacemakers to X-ray machines and other diagnostic imaging equipment — for electromagnetic compatibility (EMC) per IEC 60601-1-2. Automotive component testing verifies compliance with domestic and export market regulatory requirements, while dedicated lighting and luminaire testing covers LED-based products for residential and commercial applications. The laboratory's IT and telecommunications testing services address the growing regulatory complexity of wireless communication devices and smart-connected systems. YMPL tests wireless communication equipment and networked devices for conformance with applicable EMI/EMC standards, supporting market-approval submissions. For industrial automation and control systems, YMPL offers performance verification and compliance testing of embedded measurement hardware. Environmental and mechanical stress test facilities — covering vibration, shock, humidity cycling, and temperature cycling per the IEC 60068 test series — enable comprehensive product qualification across all of these sectors, from type approval through production batch verification. YMPL holds multiple internationally recognised accreditations that provide formal traceability and third-party assurance for all test results. The National Accreditation Board for Testing and Calibration Laboratories (NABL), India, has accredited YMPL for electro-technical calibration since 30 September 1996, and for electrical testing since 15 September 2001. In parallel, the United Kingdom Accreditation Service (UKAS) has accredited YMPL for electro-technical calibration since 29 April 1999, and for electrical testing since 10 April 2003 — making it one of very few Indian private laboratories to hold concurrent NABL and UKAS accreditation in the electro-technical domain. The laboratory operates under ISO/IEC 17025:2017 and is also recognised by the Bureau of Indian Standards (BIS), completing a multi-body accreditation portfolio that is accepted by regulators, utilities, and procurement teams worldwide. Complementing its testing operations, YMPL runs a dedicated Training Academy that develops metering technology expertise among practising engineers and technicians. As India accelerates smart-meter deployment under the Revamped Distribution Sector Scheme (RDSS), demand for skilled professionals in advanced metering infrastructure, calibration, and energy auditing is intensifying; YMPL's training programmes are structured to close that skills gap. The combination of more than 25 years of operational history, rare dual NABL and UKAS accreditation, a fleet of advanced test equipment operated by qualified staff, and the unique 220 kV MobiLAB on-site service makes Yadav Measurements Private Limited a highly credible and versatile testing partner for manufacturers and utilities operating anywhere in India and targeting international certification.
