Weights and
Measures (International Definitions) (Jersey) Order 1968[1]
THE ENVIRONMENT
AND PUBLIC SERVICES COMMITTEE, in pursuance of paragraph
3 of Part 1, paragraph 3 of Part 4, paragraph 5 of Part 5 and paragraph
1 of Part 6 of Schedule 1 to the Weights and Measures
(Jersey) Law 1967, orders as follows –
Commencement [see endnotes]
1
The
metre, litre, kilogramme, ampère, watt, volt and ohm shall, for the
purposes of measurements falling to be made in Jersey, have the meanings
respectively assigned to them in the Schedule to this Order, being the meanings
appearing to the Minister to reproduce in English the international definitions
of the said units in force at the date of the making of this Order.
2
This Order may be cited
as the Weights and Measures (International Definitions) (Jersey)
Order 1968.
SCHEDULE
(Article 1)
DEFINITIONS OF UNITS OF MEASUREMENT
MEASUREMENT OF LENGTH
Metre
The metre is the length
equal to 1 650 763.73 wavelengths in vacuum of the radiation corresponding to
the transition between the levels 2p10 and 5d5 of the
krypton – 86 atom.
(General Conference of
Weights and Measures held in Paris in 1960).
MEASUREMENT OF CAPACITY
Litre
The litre is the volume
occupied by a mass of 1 kilogramme of pure water at its maximum density and
under standard atmospheric pressure.
(General Conference of
Weights and Measures held in Paris in 1901).
MEASUREMENT OF MASS
Kilogramme
The kilogramme is the
unit of mass represented by the mass of the international prototype kilogramme.
(General Conference of
Weights and Measures held in Paris in 1901).
MEASUREMENT OF ELECTRICITY
Ampère
The ampère is the
constant current which, if maintained in 2 straight parallel conductors of
infinite length and of negligible circular sections and placed 1 metre apart in
vacuum, will produce between the conductors a force equal to 2 ´ 10-7 M.K.S. units of force per metre of length.
(General Conference of
Weights and Measures held in Paris in 1948).
Watt
The watt is the power
which gives rise to the production of energy at 1 joule per second.
(General Conference of
Weights and Measures held in Paris in 1948).
Volt
The volt is the difference of electrical potential between 2 points
of a conducting wire carrying a constant current of 1 ampère when the
power dissipated between these 2 points is equal to 1 watt.
(General Conference of
Weights and Measures held in Paris in 1948).
Ohm
The ohm is the electrical
resistance between 2 points of a conductor when a constant difference of
potential of 1 volt applied between the 2 points produces in the conductor a
current of 1 ampère, the conductor not being the seat of any
electromotive force.
(General Conference of
Weights and Measures held in Paris in 1948).
Note
The reference in relation
to each definition to a General Conference of Weights and Measures is a
reference to the General Conference of Weights and Measures (convened by the
International Bureau of Weights and Measures) at which that definition was recognized.
