BACKGROUND
• Round robin – confirmed reproducibility and repeatability of solar reflectance testing
• Specification to implement procedure−Prepared vs. commercially-available substrate
−Thermal emittance testing
−Weathering/field exposure

SUBSTRATE
• Discussed commercial substrate −Potential to reduce error in preparation
−Ease of preparation
• M&I confirmed use of prepared substrate at December 2016 meeting
−Round Robin confirmed reproducibility and repeatability
−No study using commercial product as substrate

THERMAL EMITTANCE
TESTING
• Applicability of slide method discussed−Potential damage to equipment
• Devices & Services completed preliminary testing
−0.002 to 0.006 higher – slide method
−Surface temperature effect
−Surface roughness effect (0.018 displacement)
• Effects minimal and tend to offset one another
