Determining the light transmittance with this application is preferred to measuring the photometric transmittance using methods that use the sun as the source and a photometer as the detector, except for transmitting inhomogeneous, patterned or corrugated sheet materials.

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