5. Title, number of pages and language(s) of the notified document: DUS 1999: 2018, 
Standard Test Method for Measurement of Retroreflective Pavement Marki ng Materials with 
CEN-Prescribed Geometry Using a Portable Retroreflectometer, First Edition. (15 page(s), 
in English)   
6. Description of content: This Draft Uganda  Standard  covers the measurement of the 
retroreflective properties of horizontal pavement marking materials containing 
retroreflecting beads, such as traffic stripes and surface symbols, using a portable 
retroreflectometer that can be placed on the road delineation to measure the 
retroreflection at a prescribed geometry. The restriction to bead  based materials is for the 
purpose of ensuring a sufficiently gradual optical response function (from points of the 
source aperture to points of the receiver aperture) to allow generous sized instrument 
source and receiver apertures.  
The entrance and obse rvation angles of the retroreflectometer affect the readings. As 
specified by the European Committee for Standardization (CEN), the entrance and 
observation angles shall be 88.76° and 1.05°, respectively. This test method is intended to 
be used for field m easurement of pavement markings but may be used to measure the 
performance of materials on sample panels before placing the marking material in the 
field.
