also noted, "The kelvin is currently defined in terms of an intrinsic property of water that, while being an invariant of nature, in practice depends on the purity and isotopic composition of the water used.
The spread of the katal in routine medical laboratory reporting, however, has been sporadic, and apart from general inertia, the argument was often advanced that the special term lacked adoption by CGPM for use with the SI.
Finally, the IFCC petition and the related CCU and CCQM Recommendations were put before the 21st CGPM meeting in October 1999, which adopted the combined recommendations summarized above.
The katal is now adopted under the Convention of the Metre of 1875 by the highest metrologic authority, the intergovernmental diplomatic CGPM, to express quantity values of catalytic activity of enzymes and other catalysts in any field of science and technology.
Journals subscribing to the preferred use of SI units can now with the blessing of the CGPM promote international standardization of units by including the katal in their Information for Authors, thus facilitating the globalization of medicine.
A ce propos, il precisera que la CGPM
ambitionne de moderniser la peche industrielle dans la region, la valoriser sans porter atteinte aux ressources.
The culmination of this discussion is Draft Resolution A considered by the 24th CGPM at its October 2011 meeting (10), which was prepared by the CIPM upon the recommendation of its CCU.
6, Appendix C how the definition of the current SI can be recast into a fully equivalent form that is identical to the two-part form proposed for defining the New SI by the CIPM and which is under consideration by the CGPM for eventual adoption.
4, Appendix A, the CGPM formally established the SI in 1960, some 50 years ago.
In 1921, the Sixth CGPM
modified the Meter Convention to extend the scope of the BIPM and CIPM to cover electrical measurements.
In 1979 the CGPM
adopted a recommendation from the International Committee on Weights and Measures (CIPM) and redefined the candela in terms of a specific amount of optical power:
In 1960, the 11th CGPM
adopted the newton as the unit of force in the International System of Units (SI), where one newton is the force required to accelerate a mass of one kilogram to one m/[s.
