Scope

Systematic review results and committee decision to revise as several errors to fix.

BS 8493 specifies the method of test to determine the Light Reflectance Value (LRV) of different surfaces of materials. LRV is the proportion of visible light reflected by a surface compared to the sensitivity to light of the human eye.

Purpose

To revisit and update the outdated references and text. Ensure that the descriptions of the equipment needed to make the LRV measurements are still current and that the method of measurement of sample surfaces remains accurate.
