BS 7920:2005

This standard BS 7920:2005 Luminance meters. Requirements and test methods is classified in these ICS categories:

• 29.140.40 Luminaires
• 17.180.20 Colours and measurement of light

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 standard are identical to the requirements specified for a luminance meter in BS EN 13032-1. However, BS EN 13032-1 specifies additional requirements which are not specified in this standard.
