ASTM E808 Practice for Describing Retroreflection

ASTM E808 is a standard method to determine the reflectance properties of materials by determining the angle between the direction of the incident radiation and the direction of view. This test method is important to determine the proper terminologies, geometrical coordinate systems, and procedures required to evaluate retroreflector performance and measure retroreflection. The results are crucial for various lab settings and are used to enhance various industrial applications.

    Introduction to ASTM E808

    ASTM E808 is an important test method to evaluate the retroreflection properties of materials to assess their quality and durability. In this method, the ability of materials to reflect the light back to their source is determined and used to enhance various applications such as road signs, markings for traffic, and safety signs. ASTM E808 provides geometric coordinate systems that are applicable worldwide and enhance the visualization of relationships between various angles. MatestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to conduct ASTM E808 tests for our clients.

    ASTM E808 Test Method

    The method proceeds as follows:

    Instrument SetupThe ASTM E808 involves preparing the specimen and emitting a light beam onto the specimen at a defined angle through a reflectometer. The amount of light reflected in the direction from where it came is measured.  
    Data Acquisition and AnalysisThe testing conditions are maintained throughout the test and the retroreflection measurements are taken based on the data obtained. The findings are then presented in a comprehensive report. 

    ASTM E808 Specimens

    Specimen DetailsThe ASTM E808 specimens used are flat-shaped materials capable of reflecting light.    
    Specimen dimensionsThe acceptable specimen size varies with the testing requirements. 
    Specimen PreparationThe ASTM E808 specimens are cleaned and prepared as per requirements.

    ASTM E808 Results

    The results obtained from the ASTM E808 test method help determine the retroreflection properties of materials and assess their performance in various projects, such as the effective visualization of roads or traffic signs. These findings aid in product optimization, quality control, performance evaluation, and research.

    Tests Related to ASTM E808

    ASTM E808 is similar to other standard methods, such as ASTM E809 and ASTM E810, used for determining the photometric characteristics of reflectometers and outlines the procedure for determining the coefficient of retroreflection of retroreflective sheeting, respectively.
