1. (I) These rules may be called as the Legal Metrology (National Standards) (Amendment) Rules, 2019.
(2) They shall come into force on the date of their publication in the Ofticial Gazette.
2. In the Legal Metrology (National Standards) Rules, 2011,-
(a) for rules 4, 5, 6, 7, 8,9 and 10, the following rules shall be substituted, namely:- ['l1JTT JJ-~ 3(i)] 3 "4. Base units of Length- The base unit of length shall be the metre, symbol rn, which is detined by taking the tixed numerical value of the speed of light in vacuum c to be 299792458 when expressed in the unit ms'", where the second is defined in terms of the caesium frequency 60".
5. Base units of Mass- The Base unit of mass shall be the kilogram, symbol kg, which is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015xI0-34 when expressed in the unit 1 s. which is equal to kgmZs-l, where the metre and the second are defined in terms of c and 6IJe,·
6. Base unit of time- The base unit of time shall be the second, symbol s, which is defined by taking the fixed numerical value of the caesium frequency 60es' the unperturbed ground-state hyperfine transition frequency of the caesium-133 atom, to he 9192631770 when expressed in the unit Hz, which is equal to S-l
7. Base unit of electric current - The base unit of electric current shall be the ampere. symbol A. which is detined by taking the fixed numerical value of the elementary charge e to be 1.602176634x 10-IYwhen expressed in the unit h.
which is equal to A s, where the second is defined in terms of 6IJe,.
8. Base unit of thermodynamic temperature- (I) The Base unit of thermodynamic temperature shall be the kelvin.
symbol K. which is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380649xI0-z3 when expressed in the unit 1K-1• which is equal to kgm2s-2K-1, where the kilogram. metre and second are defined in terms of h.
(' and 60cs.
(2) The Kelvin shall also be used for expressing the interval or difference of temperature.
(3) Zero degree Celsius corresponds to 273.15 kelvin.
(4) The degree Celsius may also be used for expressing the interval or difference of temperature, unit degree Celsius being equal to unit Kelvin.
9. Base unit of luminous intensity.- The base unit of luminous intensity shall be the candela. symbol cd, in a given direction which is defined by taking the fixed numerical value of the luminous efficacy of monochromatic radiation of frequency 540x I012 Hz. Ked. to be 683 when expressed in the unit 1m»r', which is equal to cd sr »r', or cd sr kg-l m-2 S3. where the kilogram. metre and second are defined in terms of h, c and 60".
10. Base unit of amount of substance.- (I) The base unit of amount of substance shall be the mole, symbol mol. which contains exactly 6.02214076x1023 elementary entities. This number is the fixed numerical value of the Avogadro constant. NA• when expressed in the unit mol-l and is called the Avogadro number. The amount of substance. symbol n, of a system is a measure of the number of specified elementary entities. An elementary entity may be an atom. a molecule, an ion, an electron, any uther particle or specified group of particles.
(2) When the mole is used, the elementary entities shall invariably be specified and may be atoms. molecules.
ions, electrons, other particles, or specified groups of such particles".
