BS 667:2005 PDF

1   Scope This British Standard specifies performance requirements for illuminance meters for the measurement of photopic illuminance for applications other than the measurement of luminaires. It specifies the performance requirements for two types of illuminance meter, Type L (laboratory instruments) and Type F (field instruments). This British Standard is applicable to meters for the measurement of planar illuminance . This standard is intended for use by meter manufacturers and users.

NOTE 1 The requirements specified for a Type L meter in this standard are identical to the requirements specified for an illuminance meter in BS EN 13032‑1. However, BS EN 13032‑1 specifies additional requirements which are not specified in this standard.

NOTE 2 If other types of illuminance e.g. semi-cylindrical, are used, reference should be made to CIE Publication 69:1987 [1].

NOTE 3 Annex A gives recommendations for the choice of meter range.
