15、trae 9/9AForeword International Standards produced by the Commission Internationale de lEclairage are concise documents on aspects of light and lighting that require a unique definition. They are a primary source of internationally accepted and agreed data which can be taken, essentially unaltered,
16、into universal standard systems. This CIE International Standard has been prepared by CIE Technical Committee 2-401“Characterizing the Performance of Illuminance and Luminance Meters”. It has been approved by the Board of Administration and Division 2 of the Commission Internationale de lEclairage a
17、s well as by the CIE National Committees. It is supposed to supersede CIE Publication 69-1987. 1This TC was chaired by R. Rattunde (DE) and P. Blattner (CH). Members were: R. Austin (US), J.

31、 rights reservedCharacterization of the Performance of Illuminance Meters and Luminance Meters 1 Scope This CIE International Standard is a pplicable to illuminance and luminance meters. The Standard defines quality indices characterizing the performance of such devices in a general lighting measure
32、ment situation, as well as measurement procedures for the individual indices and standard calibration conditions. Measurements of illuminance or luminance and their accuracy are influenced by various parameters, such as operational conditions, properties of light sources, as we ll as characteristics
33、 of the applied photometers. The characteristics of these photometers alone do not allow the determination of the measurement uncertainty for a specific measurement task. Nevertheless, it is generally true that instruments with “better” characteristics in most cases produce smaller uncertainties tha
34、n instruments with “worse” properties. This Standard has been written to: give clear and unambiguous definitions for the individual quality indices; define measurement procedures and methods for numerical evaluation of these quality indices; define calibration conditions for illuminance meters and l
35、uminance meters. Where different, the definitions of the quality indices and the associated measurement procedures and methods for numerical evaluation given in this Standard supersede those given in CIE Publication 53-1982. CIE publication 69-1987 shall be superseded by this Standard. 2 Normative R

41、ng Vocabulary) and the following apply. 3.1 General Definitions 3.1.1 measurement accuracy closeness of agreement between a measured quantity value and a true quantity value of a measurand Note 1 to entry: The concept measurement accuracy is not a quan tity and is not given a numerical quantity valu
42、e. A measurement is said to be more accurate when it offers a smaller measurement error. Note 2 to entry: The term “measurement accuracy” should not be used for measurement trueness and the term measurement precision should not be used for measu rement accuracy, which, however, is related to both th
43、ese concepts. Note 3 to entry: Measurement accuracy is sometimes understood as closeness of agreement between measured quantity values that are being attributed to the measurand. Source: ISO/IEC Guide 99:2007 (VIM), 2.13 3.1.2 measurement error measured quantity value minus a reference quantity valu
44、e Note 1 to entry: The concept of measurement error can be used both a) when there is a single re ference quantity value to refer to, which occurs if a calibration is made b y means of a measurement standard with a measured quantity value having a negligible measurement uncertainty or if a conventio
45、nal quantity value is given, in which case the measurement error is known, and b) if a measurand is supposed to be represented by a unique true quantity value or a set of true quantity values of negligible range, in w hich case the measuremen t error is not known. Note 2 to entry: Measurement error
46、should not be confused with production error or mistake. Source: ISO/IEC Guide 99:2007 (VIM), 2.16 3.1.3 calibration operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and co
47、rresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication Note 1 to entry: A calibration may be e xpressed by a statement, calibration function, calibration diagram, cal
48、ibration curve, or calibration table. In some cases, it may consist of an additive or multiplicative correction of the indication with associated measurement uncertainty. Note 2 to entry: Calibration should not be confused with adjustment of a measuring sy stem, often mistakenly called “self-calibra
49、tion”, nor with verification of calibration. Note 3 to entry: Often, the first step alone in the above definition is perceived as being calibration.
