The evaluation and the characterization of the colour
constitute critical
factors of the process of quality control of products,
that also must take care of
requirements imposed by customers and final consumers. The
colour of an object
depends greatly on the characteristics of the
illumination. In this context, this
research is aimed at discussing the different
international standards that
characterize the performance of the daylight simulators
used in instrumental
(spectrophotometers) and visual (light booths) evaluations
and also at analysing
the differences between the various methods specified in
these standards. To
reach these objectives the measurement conditions
established by the CIE
(interval and spectral band-width) were verified and
elaborated and validated
procedures for the measurement of different luminous
sources. Based on these
procedures, measurements of daylight simulators were
carried out to acquire
their spectral power distributions. The measurement
results were then used to
analyze the evaluations methods specified in standards.
The following main
results have been accomplished: (i) the CIE
recommendations for the
measurement of luminous sources must, in fact, be
incorporated into the
measurement process; (ii) the increase in the metrological
reliability through the
validation of the spectroradiometric procedures based on
the analyses of the
repeatability of the measurements; and (iii) the
comparison established among
the different evaluation methods of daylight simulators,
leading to the distinction
between the presence or the lack of correlation present in
the different methods
investigated. The work also contributed by the
introduction of standard routines to
express the uncertainty associated with spectroradiometric
measurements.
