Abstract:
The traditional approach for the establishment of a metrology infrastructure in other countries has been established as central laboratory,call
generically National Metrology Institute (NMI) which has an official recognition to enhance the capacities of measurement of the country or economy.
Chile has took the decision to have a Network more than an unique NMI,so at the present time,the structure of the Network is included by 7 magnitudes
managed by 6 Institutions,CESMEC (mass and temperature), IDIC (force) and ENAER (pressure),DICTUC S.A. (length),CISA (Liquid Flows) and University
of Conception (electrical Magnitudes).

Resumen.
La aproximación tradicional para implentar una insfraestructura metrológica en otros países se ha logrado cuando un laboratorio central,de-
nominado genéricamente Instituto Nacional de Normalización (INN/NMI) con un reconocimiento oficial para respaldar las capacidades de medición del
país o economía.Chile tomó la decisión de crear una Red y no una institución única o INM,por lo que en este momento, la estructura de la Red incluye
siete magnitudes,administradas por seis instituciones:CESMEC Ltda. (Masa y Temperatura); IDIC (Fuerza);ENAER (Presión);DICTUC S.A. (Longitud);CISA
(Flujos Líquidos) y la UNIVERSIDAD DE CONCEPCION (Magnitudes Eléctricas).

I. Introduction
The traditional approach for the establishment of a metrology infrastructure in other countries has been estab-
lished as central laboratory, call generically National Metrology Institute (NMI) which has an official recognition to
enhance the capacities of measurement of the country or economy.Within each country the National Metrology
Institutes (NMIs) are designated to develop and maintain national standards for one or several quantities. The
institutional arrangements for NMIs are as varied as the countries themselves. Some countries centralize all the
national standards to one institution, others decentralize widely. Many NMIs are wholly owned by their govern-
ments, others are semi-private agencies and others are wholly private. A number of NMIs are also primary labora-
tories, which are internationally recognized for providing primary standards. Some NMIs are exclusively reference
laboratories, which provide a national standard traceable to a primary standard. Many NMIs concentrate on pure
metrology whereas others have a range of activities including commercial interests.[1]
In addition to that, it is not necessary that the national metrology standard are located closely together of the
international standards. It is only necessary that standard must be recognized and be used like standard for the
calibrations required by the industry of the country.
The difficulty of the centralize scheme is in the highest cost to maintain that infrastructure, considered in several
tens of millions of dollars. For that reason and from an effective reduction of the fiscal apparatus in Chile for al-
ready several years, it became necessary to look for an alternative that allowed to conjugate the necessities of the
metrology with the real sources of financing.
Taking the advantage for the already existing potentialities in some national institutions and their experience
about metrology, it was created an integrated system that works in a coordinated form.This system was denomi-
nate National Metrology Network (RNM), because it is compound of 7 National Standard Laboratories (LCPN)
who grants the traceable to the international units to a second level of 40 Calibration laboratories (LC) and finally
destined to scatter the units to the national industry. Fig 1 illustrates in schematic form the configuration of the
RNM and its relation with the rest of the productive organizations.
