    Abstract

    Illuminance scale is one of the fundamentals in the realisation of candela in optical radiation. The en route of the realisation is based on the fundamental process from the unbroken chain of traceability which includes from the primary standard disseminated to working standard and lastly the end user. There are many variations towards this realisation even though some of the national metrology institutes (NMI) does not have the primary standard but their traceability still valid. The realisation of National Metrology Laboratory SIRIM (NML-SIRIM), Malaysia illuminance scale is based on detector. The scale is traceable to National Physical Labortaory (NPL), United Kingdom (UK) by annually calibrating photometers and luminous intensity lamp. This paper describes measurement method and the system set-up was previously crosschecked with Korea Research Institute Standards and Science (KRISS), Republic of Korea. The agreement between both laboratories is within 0.5% the uncertainty maintained at NML-SIRIM. Furthermore, the basic measurement equation for illuminance realisation is also derived
