ISO Guide 32: Calibration in analytical chemistry and use of certified reference materials
（修订中，将与ISO Guide 33合并）
Quality assurance in a testing laboratory, particularly
in the case of its assessment (see ISO/IEC Guide 25), highlights the need to
consider closely the question of the accuracy of its measurements and
analytical results, and to ensure that the principles necessary to establish
demonstrated accuracy have not been omitted.
The calibration of the parameters associated
with chemical analyses and material testing deserves particular attention,
because major errors can be made by neglecting or ignoring the basic principles
of metrology which also apply to these areas. This Guide identifies a number of
general recommendations for those who, either in laboratories or as assessors,
are faced with this problem.
