The reticle retroreflection measuring instrument is a portable field measuring instrument with an open optical path, which is used to measure the retroreflection brightness coefficient of the reticle. Unit: mcd·m-2·lx-1.
The main characteristics of its research are: simulating a motor vehicle driving on the road at night, the headlights illuminated on the road (made of retro-reflective material) markings, after reflection, the brightness observed by the driver in the cab, The parameter measured is the nighttime retroreflection luminance coefficient, or RL value.
This instrument can measure the reticle and oscillating reticle retroreflection luminance coefficient under three conditions: dry R_L, wet R_(L_wet) and continuous rainfall R_(L_rain). This instrument complies with the following standards: GB/T 26377-2010 “Retroreflection Measuring Instrument”, GB/T16311-2009 “Quality Requirements and Testing Methods for Road Traffic Markings”,
JJG(Traffic) 059-2004 “Retroreflective Measuring Instrument Verification Regulations” “, support JTGF80-1-2017 “Highway Engineering Quality Inspection and Evaluation Standard”, DB36/T978-2017 “Rainy Night Road Traffic Reflective Line Quality Requirements and Testing Methods”, DB51/T2429-2017 “Rainy Night Highway Traffic Reflective Line Quality Requirements” and testing
methods” and other standard requirements.
