Metrology: CSIR-NPL Stands the Test of Time

Hailed as the Time Keeper of India CSIR-NPL, provides the Indian Standard Time (IST), steadfastly promoting Metrology, the science of measurement and its application, and accuracy and precision through the ensuing decades post -Independence.

National Physical Laboratory: NPL, New Delhi

National Physical Laboratory (NPL) is one among the two scientific institutes established in the country under the aegis of CSIR in 1950. Over the years, the NPL also known as the National Measurement Institute of (NMI) India has more than realized its primary mandate as the keeper of measurement standards for the nation while also substantially expanding its research activities to emerge as a leading national institution for research in a whole gamut of areas in the Physical Sciences.

Metrology is one of the key components in improving product quality which in turn affects quality of life. For instance, home appliances have to meet certain specifications in terms of acoustic noise, mechanical dimensions, pressure, electrical voltages and consumption.

Metrology and calibrated instruments are a must for judging the conformance to specifications. Chemical metrology and physical metrology is essential for controlling the pollutions, similarly it enables biomedical arena. Standards play a key role in Metrology.

CSIR realizing its importance was the first to establish CSIR-NPL- a dedicated laboratory for carrying out metrological activities by establishing apex level standards.

NPL through the government is part of the Metre Convention, a diplomatic treaty which was signed by representatives of 17 countries in Paris in 1875. The treaty created the International Bureau of Weights and Measures (BIPM).

An intergovernmental organization under the authority of the General Conference on Weights and Measures (CGPM).India had signed this treaty in 1957.


CSIR-NPL has successfully established equivalence with international standards. All other reference and working standards in other laboratories and industries throughout India are required to be traceable to the National Standards of Measurements maintained at the NPL.

The focus area of CSIR-NPL are on metrology arerealization of Base & Derived Units; Apex Level Calibration of physico-mechanical and electrical & electronic standards; and chemical metrology.

Few of the milestones for metrological activities carried out by NPL India include the introduction of the metric system in India ; Law of Weights and Measures promulgated (Re-issued in 1976, 1988), India joining the Meter Convention, ‘Apex Metrology Laboratory’, a highly controlled environment building for apex level measurements in 2015.

Currently CSIR-NPL provides apex calibration of equipments to various industries, strategic, academia and government agencies to the tune of six crore per year which is likely to double over the next five years. Such calibrations at CSIR-NPL are key drivers toImage result for CSIR make in india the growth engine of industries and assumes utmost significance for ensuring the success of “Make in India” mission. Accurate and precise measurements would also support Indian industry and business to innovate. This would require up-gradation of existing calibration facilities at CSIR-NPL, for which work is already underway in full swing.

The main objective of division of apex level calibration at CSIR-NPL is, realization, establishment, custody, maintenance, dissemination and upgradation of the national standards in the field of physico-mechanical and electrical and electronics standards and time and frequency standard.

In India, the research on solar cells is being pursued in various scientific laboratories and industries; however, there is no facility for the validation of solar cell efficiency. CSIR-NPL has taken up an initiative for setting up a ‘National Facility’ for validation of solar cell efficiency with the maximum possible accuracy.

Similarly, the calibrations of biomedical equipments are essential for correct diagnosis as well as treatment of the patients. This will contribute greatly to the cause of “Swasthya Bharat” mission.

On the environment front, CSIR-NPL has recently developed the 2.5 PPM sampler and it will be first of its kind in India to provide accurate and traceable measurement facility.

CSIR-NPL foresees that the quantum technologies will deliver game-changing applications ranging from faster communications to cancer detection and navigation, which will be vital to improve lives and creation of new businesses.  CSIR-NPL is gearing up its existing “Quantum Metrology” laboratory that will provide world-class measurement expertise to validate the new quantum technologies and secure the India’s position in this emerging field “Sashakt  Bharat”.

Many government and semi-government as well private sector entities have benefitted from CSIR-NPL’s support, advices and calibrations. These include Air Force, Air India, Bharat Electronics , BHEL; Bhilai Steel Plant; Bureau of Indian Standards, Defense Electronics Applications Laboratory and several prominent private sector companies.csir

Understanding Minimum Wages and Bonus


Author :Bandaru Dattatreya

A minimum wage is the lowest remuneration that employers may legally pay to workers or it is the price floor below which workers may not sell their labour.


The concept of minimum wages first evolved with reference to remuneration of workers in those industries where the level of wages was substantially low as compared to the wages for similar types of labour in other industries.

As far back as 1928, the International Labour Conference of International Labour Organization, at Geneva, adopted a draft convention on minimum wages requiring the member countries to create and maintain a machinery whereby minimum rates of wages can be fixed for workers employed in industries in which no arrangements exist for the effective regulation of wages and where wages are exceptionally low.

Also, at the Preparatory Asian Regional Labour Conference of International Labour Organisation held at New Delhi in 1947 and then at the 3rd session of the Asian Regional Labour Conference, it was approved that every effort should be made to improve wage standards in industries and occupations in Asian Countries, where they are still low. Thus, the need of a legislation for fixation of minimum wages in India received an impetus after World War II, on account of the necessity of protecting the interest of demobilized personnel seeking employment in industries.

The justification for statutory fixation of minimum wage is obvious. Such provisions which exist in more advanced countries are even necessary in India, where workers’ organizations are yet poorly developed and the workers’ bargaining power is consequently poor.

To provide for machinery for fixing and revision of minimum wages a draft Bill was prepared and discussed at the 7th session of the Indian Labour Conference in November, 1945. Thereupon the Minimum Wages Bill was introduced in the Central Legislative Assembly. The Minimum Wages Bill having been passed by the Legislature received the assent on 15th March, 1948. It came on the Statute Book as the Minimum Wages Act, 1948.

The Act provides for fixation by the appropriate Governments of minimum wages for employments covered by Schedule to the Act.  The Central Government is the appropriate Government in respect of 45 scheduled employments in the Central Sphere. The minimum wages fixed for Central sphere are applicable to the scheduled employments in the establishments under the authority of Central Government, railway administrations, mines, oil-fields, major ports or any corporation established by a Central Act. Employments other than the scheduled employment for Central Sphere come under the purview of the State Government and accordingly State Government wages are applicable in such employments.  The minimum wages for Central Sphere are revised from time to time based on the increase in Consumer Price Index effective from April and October.

According to Section 3(1)(b) of the Minimum Wages Act, 1948, “the appropriate government shall review at such intervals, as it may think fit, such intervals not exceeding five years, the minimum rates of wages so fixed and revise the minimum rates if necessary.

The norms recommended by the Indian Labour Conference, in 1957, fox fixing the minimum wages are: (a) consumption units for one wage earner; (b) minimum food requirements of 2700 calories per average Indian adult; (c) clothing requirements of 72 yards per annum per family; (d) rent corresponding to the minimum area provided for under Government’s Industrial Housing Scheme; and (e) fuel, lighting and other miscellaneous items of expenditure to constitute 20% of the total minimum wage.

In 1991, the Hon’ble Supreme Court delivered a historic judgement and directed that children’s education, medical requirement, minimum recreation including festivals/ceremonies, provision for old age, marriage etc. should further constitute 25% of the minimum wage and be used as a guide in fixation of minimum wage.

The Act envisages appointment of an Advisory Board, by the appropriate Government, for the purpose of advising the appropriate Government in the matter of fixing and revising minimum rates of wages.

The Central Government revises the wages in the scheduled employments from time to time in accordance with the provisions of the Minimum Wages Act, 1948. Draft Notifications for all the Scheduled Employments in the Central Sphere were issued on 1st September, 2016 simultaneously, in fact for the first time.

The basic rate of minimum wages for an unskilled worker in the scheduled employment other than agriculture has been proposed at Rs.350 in Area ‘C’ from the current minimum wage (basic wage + variable dearness allowance) of Rs.246 resulting in an increase of about 42%. The basic rate of minimum wages for an unskilled worker in the scheduled employment “agriculture” has been proposed at Rs.300 in Area ‘C’ from the current minimum wage (basic wage + variable dearness allowance) of Rs.211 resulting in an increase of about 42%.

The proposed revision in the rates of basic minimum wages would indeed provide much needed solace to the labour fraternity.

Bonus payment is an extra payment given for doing one’s job well also known as  performance-related pay or pay for performance.

The practice of paying bonus in India appears to have originated during First World War when certain textile mills granted 10% of wages as war bonus to their workers in 1917.  In certain cases of industrial disputes demand for payment of bonus was also included.  In 1950, the Full Bench of the Labour Appellate Tribunal evolved a formula for determination of bonus.  A plea was made to raise that formula in 1959.

At the second and third meetings of the eighteenth Session of Standing Labour Committee (G.O.I) held in New Delhi in March/ April 1960, it was agreed that a Commission be appointed to go into the question of bonus and evolve suitable norms.  A Tripartite Commission was set up by the Government of India to consider in a comprehensive manner, the question of payment of bonus based on profits to employees employed in establishments and to make recommendations to the Government.  The Government of India accepted the recommendations of the Commission subject to certain modifications.  To implement these recommendations the Payment of Bonus Act, 1965 was enacted, which came into force on 25-9-1965.

The objective of the Payment of Bonus Act, 1965 is to provide for the payment of bonus to the persons employed in certain establishments on the basis of profits or on the basis of production or productivity and for matter connected therewith.

It applies to (i) Every Factory; and (ii) Every other establishment in which 20 or more persons are employed on any day during an accounting year subject to the exemptions under section 32. Every employee shall be entitled to be paid by his employer in an accounting year, bonus, in accordance with the provisions of this Act, provided he has worked in the establishment for not less than thirty working days in that year. While the minimum bonus is 8.33% of the salary or wage earned by the employee during the accounting year, the maximum bonus is 20% of such salary or wage.

Two ceilings are available under the said Act generally known as eligibility limit and calculation ceiling respectively. Clause 13 of Section 2 of Payment of Bonus Act, 1965 defines an employee based on salary or wage per mensem. This is usually taken as the “eligibility limit” for computation of bonus. Similarly, Section 12 of the Payment of Bonus Act, 1965 provides for calculation of bonus of an employee based on salary or wage per mensem. This is known as “calculation ceiling”.

The two ceilings are revised from time to time to keep pace with the price rise and increase in the salary structure. At present, the calculation ceiling has been enhanced to Rs.7000 or the minimum wage for the scheduled employment, as fixed by the appropriate Government, whichever is higher and the eligibility limit has been enhanced to Rs.21,000/-.

Due to this revision, additional 55 lakh workers would be benefited.  This would indeed, be a good gesture on the part of the Government towards the labour fraternity.
