Abstract

Identifies the factors that influence variability in lighting performance and gives recommendations on how such variability may be contained within tolerable limits in the specification, calculation and measurement of interior and exterior lighting systems. Provides advice on the comparison of calculated/measured values of lighting parameters with specified or target values, taking into account the uncertainties of calculation/measurement. Sets out typical uncertainties that might be expected for various elements of lighting calculations/measurements, together with total uncertainties for the overall design.

Scope

This Standard identifies the factors that influence variability in lighting performance and gives recommendations on how such variability may be contained within tolerable limits in the specification, calculation and measurement of interior and exterior lighting systems. It applies particularly where quantitative values of lighting parameters are specified, but does not cover qualitative or aesthetic attributes of lighting systems except where these involve specific lighting performance parameters. The Standard sets out typical accuracies that might be expected for various elements of the calculation/measurement process, as well as the range of accuracies that can be expected for the overall design. These can be taken to apply unless otherwise specified, e.g. in a Standard covering the application, or by the client.
NOTE: Attention is drawn to AS/NZS 3827.2, which sets out the minimum requirements that should be complied with in order for a design or verification to be considered of an acceptable accuracy with respect to the achievement of specified values of light technical parameters.
