Why are environmental conditions (e.g. temperature, relative humidity) not specified on the CofA for the UV Calibration Kit?

The UV Calibration Test Replacement Absorbance Solutions are made in controlled laboratory conditions of 20–25 °C. Within this temperature range, the variability on CofA values is not significant and therefore not reported. The stray light test, which is temperature sensitive, includes a temperature correction factor in the software, allowing the user to correct for unusual laboratory temperatures. […]
