Luminance meters. Requirements and test methods Ingestion-build-201039 using blast- cleaning techniques1 Scope This British Standard specifies performance requirements for luminance meters for the measurement of photopic luminance for applications other than the measurement of luminaires. It specifies the performance requirements for two types of luminance meter, Type L (laboratory instruments) and Type F (field instruments). This standard is intended for use by meter manufacturers and users. NOTE The requirements specified for a Type L meter in this
