CONTAINED IN VOL. 12.02, 2015 Covers the measurement of solar energy transmittance and reflectance (terrestrial) of materials in sheet form: - Method A, using a spectrophotometer, is applicable for both transmittance and reflectance and is the referee method; - Method B is applicable only for measurement of transmittance using a pyranometer in an enclosure and the sun as the energy source.

1.1 These test methods cover the measurement of solar energy transmittance and reflectance (terrestrial) of materials in sheet form. Method A, using a spectrophotometer, is applicable for both transmittance and reflectance and is the referee method. Method B is applicable only for measurement of transmittance using a pyranometer in an enclosure and the sun as the energy source. Specimens for Method A are limited in size by the geometry of the spectrophotometer while Method B requires a specimen 0.61 m (2 ft). For the materials studied by the drafting task group, both test methods give essentially equivalent results.

1.2 This standard does not purport to address all of the safety problems, 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.
