Organization: ASTM International
Publication Date: 10 February 2003
Status: inactive
Page Count: 8
ICS Code (Colours and measurement of light): 17.180.20
significance And Use:

Measurements made by this test method are related to visual observations of retroreflective sheeting as seen by the human eye when illuminated by tungsten-filament light sources such as a motor... View More

scope:

1.1 This test method describes the instrument measurement of the retroreflective performance of retroreflective sheeting.

1.2 The user of this test method must specify the entrance and observation angles to be used.

1.3 This test method is intended as a laboratory test and requires a facility that can be darkened sufficiently so that stray light does not affect the test results.

1.4 Portable and bench retroreflection measuring equipment may be used to determine RA values provided the geometry and appropriate substitutional standard reference panels, measured in accordance with this test method, are utilized. In this case the methods of Procedure B in Practice E809 apply. Additional information on the use of portable retroreflectometers may be found in Test Method E 1709.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
