MEASUREMENT LAW. JAPAN
Chapter ‡T General Provisions
Article 1
The purpose of this Law is to establish the standards of measurement and secure administration of proper measurement and thereby to contribute toward the development of economy and uplifting of culture.
Article 2
1.The term gmeasurementh as used in this Law shall mean to measure the following matters (Hereinafter referred to as gquantity of the state of physical phenomenah) and the term gmeasuring unitsh shall mean the standards for measurement :
(1)Length, mass, time, electric current, temperature, amount of substance, luminous intensity, angle, solid angle, area, volume, angular velocity, angular acceleration, velocity, acceleration, frequency, rotational frequency, wave number, density, force, moment of force, pressure, stress, viscosity, kinematic viscosity, work, power, mass flow rate, flow rate, quantity of heat, thermal conductivity, specific heat capacity, entropy, quantity of electricity, electric field strength, voltage, electromotive force, capacitance, magnetic field strength, magnetmotive force, magnetic flux density, magnetic flux, inductance, electric resistance, electric conductance, impedance, active power, reactive power, apparent power, active energy, reactive energy, apparent energy, attenuation of electromagnetic wave, electric power density of electromagnetic wave, radiant intensity, luminous flux, luminance, illuminance, sound power, sound pressure level, oscillating acceleration level, concentration, neutron emission rate, radioactivity, absorbed dose, absorbed dose rate, kerma, kerma rate, exposure, exposure rate, dose equivalent or dose equivalent rate :
(2)Linear density, specific gravity and others prescribed by Cabinet Order.
2.The term gtransactionh as used in this Law shall mean any act in business, irrespective of compensation or not, for the purpose of supply of goods or services and the term gcertificationh shall mean to express to other persons, in public or in business, that a certain fact is true.
3.The measurement, prescribed by Cabinet Order for the prevention of impairments of human lives or properties with respect to driving carriages or ships or to handling explosives, gases and other dangerous materials shall be deemed to be certification in the application of this Law.
4.The term gmeasuring instrumentsh as used in this Law shall mean appliances, machines or equipment used for measurements and the term gspecified measuring instrumentsh shall mean measuring instruments used in transaction or certification, or supplied chiefly for the life of general consumers and prescribed by Cabinet Order as being necessary to establish the standards with respect to the construction or the instrumental error for the purpose of securing performance of proper measurements.
5.The manufacture of measuring instruments in this Law shall include remodelling prescribed by the Minsistry of International Trade and Industry Ordinance and the repair of measuring instruments shall include remodelling other than that prescribed by the same Minsistry of International Trade and Industry Ordinance.
6.The term greference materialh as used in this Law shall mean a material attached with the specified value of the quantity of the state of physical phenomena prescribed by Cabinet Order and used for measurements of instrumental errors of measuring instruments for measuring the same quantity of the state of the physical phenomena.
7.The term gcalibration of a measuring instrumenth as used in this Law shall mean to measure the difference between the quantity of the state of physical phenomena which the measuring instrument indicates and the specified quantity of the state of the physical phenomena, as the standard of the measuring instrument, which the measuring instruments pertaining to the specification prescribed in Article 134 Paragraph 1, or the reference material manufactured by use of the appliances, machines or equipment pertaining to the specification prescribed by the same Paragraph, represent.
8.The term gvaluing of a reference materialh as used in this Law shall mean to revise the value of the quantity of the state of physical phenomena given to the reference material by measuring the difference between that quantity of the state of physical phenomena and the specified quantity of the state of the physical phenomena, as the standard of the measuring instrument, which the reference material manufactured by use of the appliances, machines or equipment pertaining to the specification prescribed in Article 134 Paragraph 1, represents.
