1、 Overview
The ZTT-201C raised road sign measuring instrument is an instrument that measures the main performance index of raised road signs - luminous intensity coefficient. This instrument is suitable for photometry laboratories, testing centers, traffic management departments, and road construction sites; It is also applicable to the inspection of product quality by protruding road sign manufacturers. The measuring object of this instrument is a rectangular raised landmark. The main technical basis for the design of this instrument is China's national standard GB8416-2003 "Visual Signal Surface Color", GB/T3978-2008 "Standard Lighting Body and Geometric Conditions", GB/T3979-2008 "Measurement Methods for Object Color", GB/T24725-2009 "Raised Road Signs", GB/T 26377-2010 "Retroreflection Measuring Instruments", and JJF 1809-2020 "Calibration Specification for Retroreflection Measuring Instruments". We also referred to relevant national standards (such as ASTM-810, ASTM-E 809, DIN 67520). The detector of this instrument meets the requirements of the CIE (International Commission on Illumination) standard photometric observer, the color temperature of the light source meets the CIE standard A light source, and the geometric conditions of the instrument comply with the provisions of CIE Technical Document No. 54. Therefore, the technical conditions of this instrument are consistent with international standards.
