1、 Overview
ZTT-101A Multi angle Retroreflection Sign Measuring Instrument is a specialized instrument used to measure the retroreflection coefficient (R ′) of traffic sign materials. Applicable to quality control and testing of retroreflective marking materials by material production units, quality supervision departments, engineering construction and supervision units, etc. The design of this instrument complies with the international standard ISO 3864 (1984) and the Technical Specification No. 54 of the International Commission on Illumination (CIE), and refers to relevant national standards such as ASTM E808-01 "Retroreflection Description Standard", ASTM E809-00 "Measurement of Retroreflector Optical Performance", and ASTM E810-00 "Test Method for Retroreflective Film Retroreflection Coefficient" in the United States; German DIN 67520-1994 et al. The performance of the instrument meets the requirements of China's transportation industry standard JT/T612-2004 "Retroreflective Measuring Instrument" and meets the measurement requirements specified in the national standard GB/T18833-2012 "Reflective Film for Highway Traffic Signs".
