Note 2: The retro-reflective devices and markings for motor vehicles include retro-reflector, retro-reflective markings of carriage, rear marking plate for vehicles and their trailers and warning triangles for motor vehicles. 3.1.1 retro-reflector device mounted on a vehicle and consisting of one or more retro-reflecting optical units for improving night visibility of the vehicle Note: It is referred to as "reflector" for short. 3.1.1.1 retro-reflector (Class I) reflector whose retro-reflective area is non-triangular and whose retro-reflective angle is relatively small 3.1.1.2 retro-reflector (Class III) reflector with a triangular retro-reflective area 3.1.1.3 retro-reflector (Class IV) reflector having a non-triangular retro-reflective area but a relatively large light-emitting angle 3.1.1.4 retro-reflector (Class A) reflector that can be installed and used independently Note: Retro-reflector (Class A) in retro-reflector (Class I), retro-reflector (Class III), retro-reflector (Class IV) are denoted as retro-reflector (Class I A), retro-reflector (Class III A) and retro-reflector (Class IV A). 3.1.1.5 retro-reflector (Class B) reflector that is integrated with the signal lamp and cannot be installed and used independently Note: Retro-reflector (Class B) in retro-reflector (Class I) and retro-reflector (Class III) are denoted as retro-reflector (Class I B) and retro-reflector (Class III B). 3.1.2 retro-reflective markings of carriage reflective material or combination of reflective materials affixed or installed on the surface of the carriage to enhance the identifiability of the vehicle Note: It is referred to as "retro-reflective marking" for short. 3.1.2.1 retro-reflective sheeting for the markings of carriage strip-shaped retro-reflective sheeting for application as reflective identification 3.1.2.1.1 retro-reflective sheeting for the markings of carriage (Class A) retro-reflective sheeting whose retro-reflective area color is red and white 3.1.2.1.2 retro-reflective sheeting for the markings of carriage (Class B) retro-reflective sheeting whose retro-reflective area color is orange 3.1.2.2 retro-reflector for the markings of carriage rectangular reflectors as reflective identification applications 3.1.3 rear marking plate for vehicles and their trailers flat plate having a specific shape and pattern mounted at the rear of the vehicle to increase the visibility of the vehicle Note: It is referred to as "marking plate" for short. 3.1.3.1 rear marking plate for slow moving vehicles triangular marking plate shaped as a truncated vertex angle 3.1.3.2 rear marking plate for heavy vehicles rectangular marking plate consisting of alternating strips of red and yellow materials 3.1.3.3 rear marking plate for long vehicles rectangular marking plate composed of red material in the border and yellow material in the center 3.1.3.4 rear marking plate (Class 1) marking plate with a combination of retro-reflective sheeting and fluorescent material in the retro-reflective area 3.1.3.5 rear marking plate (Class 2) marking plate with a combination of retro-reflective sheeting of different colors in the retro-reflective area 3.1.4 warning triangles for motor vehicles equilateral triangle warning equipment consisting of a retro-reflecting optical unit and a fluorescent material equipped in a motor vehicle Note 1: It is referred to as "warning triangle" for short. Note 2: It is generally used as a warning sign when a motor vehicle breaks down on the road or has a traffic accident, which hinders traffic and is difficult to move, to indicate that there is a faulty motor vehicle ahead. 3.2 retro-reflection that the light rays are reflected in a direction adjacent to the direction of incident light, and this property can still be maintained when the angle of incidence varies over a wide range 3.3 retro-reflecting optical unit smallest hard optical device that can produce retro-reflection 3.4 retro-reflective sheeting thin sheet material capable of producing retro-reflection 3.5 retro-reflective area surface enclosed in an area by the outermost edge having retro-reflective and/or fluorescent properties as specified by the manufacturer Note: The retro-reflective area of the retro-reflective sheeting is the surface on the side with retro-reflective properties. 3.6 center of reference geometric center of the retro-reflective area or the point specified by the manufacturer 3.7 the CIE co-ordinate system for retro-reflection CIE angular system for illustration and measurement of retro-reflective devices Note: See Figure A.1 in Annex A for the CIE co-ordinate system for retro-reflection. 3.7.1 axis of reference straight line passing through the center of reference, and the straight line is perpendicular to the retro-reflective area or direction specified by the manufacturer. 3.7.2 illumination axis line between the center of reference and the center of the light source 3.7.3 observation axis line connecting the center of reference and the light receiver (observation measurement point) 3.7.4 observation on half-plane half plane that starts at the illumination axis and contains the observation axis 3.7.5 first axis straight line that passes through the center of reference and is perpendicular to the observation on half-plane 3.7.6 observation angle α angle between the observation axis and the illumination axis 3.7.7 entrance angle β angle between the illumination axis and the reference axis Note: β is composed of two components, β1 and β2. 3.7.7.1 first component of the entrance angle β1 angle between the illumination axis and a plane including the reference axis and the first axis 3.7.7.2 second component of the entrance angle β2 angle between the observation on half-plane and the center of reference 3.7.8 rotation angle ε angle through which the reflective device rotates about its axis of reference, starting from an arbitrary position 3.8 luminosity 3.8.1 coefficient of luminous intensity ratio of the luminous intensity of the reflected light in the observation direction by the reflective device to the irradiance on the plane perpendicular to the incident light direction and passing through the center of reference
