Description:this practice covers the calculation of the solar reflectance index (sri) of horizontal and low-sloped opaque surfaces at standard conditions. the method is intended to calculate sri for surfaces with emissivity greater than 0.1.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. solar flux solar reflectance solar reflectance index thermal emittance
