This standard agrees in principle with ISO 2813 and ASTM

Herewith three methods for the measurement of the specular gloss
of paints with 20°, 60° and 85° geometry are specified.
The measurement results are similar to those of the visual
perception, BUT visual assessment according to Ford Laboratory Test
Method BI 109-01 will always override numerical measurement data
and is compulsory for any type of appearance approval.
