Abstract: With reference to SH/T 0404—2008 Test method for light stability of paraffin wax and GB/T 34097—2017 Test method for light stability of petroleum products. This paper introduces in detail the calibration methods of ultraviolet irradiance and temperature parameters of the paraffin light stability tester, evaluates the uncertainty of the measured values by direct measurement, and analyzes them.
Key words: paraffin light stability tester; calibration; uncertainty
