Yadav Measurements Private

Yadav Measurements Private Limited (YMPL), headquartered at Plot No. 373–375, RIICO Bhama Shah Industrial Area, Kaladwas, Udaipur, Rajasthan, India, is one of India's foremost independent and internationally accredited testing and calibration laboratories. Incorporated in 2003 and employing approximately 345 professionals, YMPL provides a comprehensive suite of type testing, calibration, certification, field services, and training to original equipment manufacturers (OEMs), utilities, government bodies, and industrial enterprises. The laboratory supports clients in achieving product certification for both Indian and international markets, verifying that products and systems comply with applicable national Bureau of Indian Standards (BIS/IS) requirements and global benchmarks including IEC, BS EN, OIML, and Australian Standards. YMPL functions as a one-stop independent testing partner from design verification through regulatory approval, serving clients across power, gas, telecommunications, healthcare, automation, automotive, and lighting sectors.

YMPL's core competency lies in the electrical testing and calibration of energy measurement equipment, with particular emphasis on type testing of static energy meters. The laboratory tests to a comprehensive range of international and national standards including IEC 62052-11, IEC 62052-21, IEC 62052-22, IEC 62052-23, IEC 61036, IEC 60687, IEC 61268, IS 13779, IS 14697, AS 1284.5, AS 1284.9 (Australian Standard), NSC M6, and CBIP Report-88. Tests performed encompass accuracy class and register compliance verification, influence quantity tests, electrical safety tests, dielectric withstand, insulation resistance, environmental stress testing per IEC 60068-2 (temperature cycling, humidity, thermal shock), and mechanical tests including vibration and shock. YMPL's BIS recognition confirms its authority to conduct type approval testing under Indian standards, providing results that are accepted by national regulatory bodies and procurement agencies.

In the electromagnetic compatibility domain, YMPL performs EMI/EMC (electromagnetic interference and electromagnetic compatibility) testing for products in the power, IT and telecommunications, automation, and consumer electronics sectors. The wireless communications revolution has driven demand for rigorous EMC testing as devices are required to operate without causing or suffering from electromagnetic disturbance. YMPL's EMC test capabilities allow OEMs to demonstrate compliance with applicable standards prior to market launch, covering both radiated and conducted emission limits as well as immunity tests to relevant IEC and IS frameworks. This capability extends the laboratory's value to manufacturers of connected devices, smart meters, industrial controllers, and wireless communication equipment entering Indian and global markets.

In the gas metering sector, YMPL provides accredited testing and calibration of diaphragm gas meters and ultrasonic domestic gas meters to standards including BS EN 1359, BS EN 14236, EN 16314, OIML R137-1&2, and IEC 60068-2. Inaccurate gas measurement creates significant financial exposure for utilities in transmission and distribution, making precise traceable calibration critical. YMPL also facilitates MID (Measuring Instruments Directive) certification for gas and energy meters through a formal partnership with Istituto Giordano (IG) of Italy and SASTEK of Turkey, providing OEMs with a structured route to CE marking and European market access. This cross-border certification partnership makes YMPL particularly valuable to manufacturers targeting simultaneous compliance in Indian and European regulatory environments.

A distinctive capability of YMPL is its MobiLAB fleet of mobile laboratories, which enables NABL-accredited on-site calibration of instrument transformers in high-voltage substations up to 132 kV, with a 220 kV MobiLAB also available for major power grid infrastructure. All MobiLAB measurements are traceable to India's national measurement standards maintained by the National Physical Laboratory (NPL) and conform to Indian and IEC specifications. This field-deployable calibration service eliminates the logistical burden of transporting large, heavy, or energized instrument transformers to a fixed facility, reducing downtime for power utilities and transmission system operators. YMPL's field service capability makes it especially valuable to power generation, transmission, and distribution companies conducting metrological verification or periodic compliance audits on in-service metering infrastructure at remote substation locations.

YMPL holds dual international accreditation under ISO/IEC 17025, the globally recognized standard for testing and calibration laboratory competence. Accreditation by NABL (National Accreditation Board for Testing and Calibration Laboratories, India) was first granted in September 1996 for electro-technical calibration and extended to electrical testing in September 2001. Accreditation by UKAS (United Kingdom Accreditation Service) was awarded in April 1999 for electro-technical calibration and in April 2003 for electrical testing. These parallel accreditations confirm that YMPL's measurement uncertainty budgets, equipment traceability chains, staff competence frameworks, and quality management processes meet the most rigorous international requirements. BIS recognition further reinforces the laboratory's standing for type approval under Indian national standards, and the MID certification partnership broadens its reach into the European conformity assessment system.

YMPL operates a dedicated Training Academy, also known as the Electricity Metering School, addressing the growing skills gap in India's rapidly evolving energy metering sector. Training programs cover energy metering technologies and advanced applications, smart meter integration, electricity revenue protection strategies, loss reduction methodologies, and NABL accreditation processes for utility meter test laboratories. Courses are designed for utility engineers, calibration technicians, and quality managers who need to build or refresh expertise as metering technology advances. YMPL additionally provides consultancy to help other laboratories obtain NABL accreditation under IS/ISO/IEC 17025, drawing on nearly three decades of accredited laboratory operation to guide clients through gap analysis, system development, and assessment preparation.
