In News: National Metrology Conclave 2021
- Prime Minister Narendra Modi recently delivered the inaugural address at the National Metrology Conclave 2021.
- The Conclave was organised by Council of Scientific and Industrial Research-National Physical Laboratory (CSIR-NPL), on its 75th year of formation. The theme of the conclave is Metrology for the Inclusive Growth of the Nation.
- At the conclave, the PM dedicated the National Atomic Timescale and Bhartiya Nirdeshak Dravya Pranali to the Nation.
What is Atomic time?
- Atomic time, is a timescale generated by atomic clocks. The International Atomic Time (TAI, from the French name temps atomique international) is based on the combined output of some 400 highly precise atomic clocks.
- Signals from these atomic clocks are transmitted to the International Bureau of Weights and Measures in Sèvres just outside Paris, which uses them to form TAI.
- International Atomic Time (TAI) is one of the main components of Coordinated Universal Time (UTC).
What is Atomic clock?
- An atomic clock is the most accurate type of timepiece in the world, designed to measure time according to vibrations within atoms (usually caesium or rubidium).
- Atomic clocks are used to coordinate systems that require extreme precision, such as Global Positioning System (GPS) navigation and the Internet.
- A group of atomic clocks located in a number of places throughout the world is used to establish Coordinated Universal Time (UTC), the time scale used to determine local times around the world.
About: National Atomic Timescale
- Precise time with nanosecond accuracy is generated and maintained over world using atomic clocks at national measurement institutes (NMIs) in more than 70 countries including India.
- CSIR-NPL is the NMI of India and authorized (by an act of Parliament) to release and maintain the Indian Standard Time.
- Through CSIR-NPL’s National Atomic Timescale, India has become self-reliant in measuring the time within the range of a nano second.
- Now Indian Standard Time is matching the International Standard Time with the accuracy range of less than 3 nano second.
- The atomic clocks maintained by CSIR-NPL are so accurate that they would lose or gain one second in about three lakh years.
Significance of National Atomic Timescale:
- It will significantly aid organizations like ISRO, that are working with in highly advanced technological domains.
- Modern technology related banking, railways, defence, health, telecom, weather forecast, disaster management and many similar sectors will also benefit from this achievement.
- The timescale will also play a big role in strengthening India’s role in Industry 4.0.
Bharatiya Nirdeshak Dravya:
- Bharatiya Nirdeshak Dravyas (BNDs) are Indian reference materials are CRMs developed by CSIR- NPL.
- The Bhartiya Nirdeshak Dravya is supporting testing and calibration of laboratories for quality assurance, at par with international standards.
- Reference materials (RM) play an important role in maintaining the quality infrastructure of any economy through testing and calibration with precise measurements.
- A transition of India from developing state to developed state requires strengthening of its quality infrastructure and manufacturing, for which availability of indigenous standards and certified reference materials (CRMs) are important.
- The national metrological institutes of advanced economies (e.g. USA, Germany, Japan France, UK, Korea, China) have strong programs on reference material production.
- However, major industries in India depend on the other National Measurement Institutes (NMIs) for certified reference materials (CRMs), which are very costly.
- CSIR-NPL is developing the certified Indian reference material (called as Bharatiya Nirdeshak Dravya) in association with ministry of commerce and industries for self-reliant India.
Significance of BND:
- BND would enhance the national quality infrastructure in the country and help the industry to make quality products in sectors like heavy metals, pesticides, pharma and textiles by drafting a ‘Certified Reference Material System’.
- With these new standards, there is an effort to bring global identity to local products in districts across the country, which will be of particular benefit to the MSME sector.
- Complying with the International standards will help the large foreign manufacturing companies coming to India to find a local supply chain.
- It will also provide quality goods to the general consumer of India and reduce the problems faced by the exporter.
BASICS: About Metrology
- Metrology is the scientific study of measurement. It establishes a common understanding of units, crucial in linking human activities.
- In the modern world, the study of measurement is a vital component in many fields, including manufacturing, engineering, science and technology. Within these fields, metrology is used to validate and verify to pre-defined standards.
- These standards are the foundation of metrology and are tested and verified against a recognised quality system by certified laboratories.
About: National Physical Laboratory (NPL)
- The National Physical Laboratory is the National Metrology Institute of India and a premier research laboratory in the field of physical sciences.
- The National Physical Laboratory was conceptualized in 1943 by the Governing Body of Council of Scientific and Industrial Research (CSIR), for using science and technology as a means for industrial growth and develop
- The foundation stone for the laboratory was laid in 1947 and it was one of the first national laboratory to be set-up under the CSIR.
- The main aim of the laboratory is to strengthen and advance physics-based research and development for the overall development of science and technology in the country.
