A measurement angle (θm) is determined from the resonance angle (θr).
In this case, the gloss indicates a value at a measurement angle of 60°, measured in conformance with ASTM-D523.
Perform the readings always with the same procedure and measurement angle
A reflex angle is an angle measuring between 180 and 360 degrees.
a) for gloss at angle of 60° according to DIN 67530
The surface gloss R'(75°) of the cast-coated paper according to the invention is less than 30 (measuring angle 75°), measured according to DIN 54502.
The inventive pigments are characterised by a CIELAB colour angle of 80 - 85°, a chroma of 58 - 62 and a luminosity ≥ 87 (measuring angle 45°, standard illuminant D65).
By providing that the transmitter (55) is separated from the receiver (56), the invention achieves a measuring angle that actually reduces the scattered light effect of the steam enough to enable reliable optical measurements of the blade vibration.
The angle of observation is the angle between the incident light and the reflected light.
