Cap. 454 Art. 16Measurement standards.

(1) The Authority shall provide, maintain or cause to be maintained such measurement standards including facilities, equipment and reference materials as are considered necessary from time to time to facilitate the realisation and dissemination of the SI System of Units of measurement, and to make funding available for such purposes.

(2) For the purpose of subarticle (1), the Authority may, upon the recommendation of the Director General, designate and delegate other organisations to be responsible bodies in specialised fields of measurement.

(4) Where any doubt arises as to the continued conformity of a measurement standard with the appropriate permissible limits of error, the measurement standard shall not be used until its value has been redetermined or it has been replaced by a measurement standard conforming to the appropriate permissible limits of error. An up-to-date certificate of traceability shall be maintained in respect of every measurement standard or set of measurement standards maintained by the Institute or any organisation designated under subarticle (2).

(5) For the purposes of this article:

(a) "reference material" means a material one or more of whose properties are sufficiently homogeneous to be measurement which is related, through an unbroken chain of comparisons, to international measurement standards.
