Organization: ASTM
Publication Date: 1 January 2008
Status: active
Page Count: 11
ICS Code (Colours and measurement of light): 17.180.20
scope:

This practice describes the general procedures for instrumental measurement of the photometric characteristics of retroreflective materials and retroreflective devices.

This practice is a comprehensive guide to the photometry of retroreflectors but does not include geometric terms that are described in Practice E808.

This practice describes the parameters that are required when stating photometric measurements in specific tests and specifications for retroreflectors.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
