Scope
Main technical content: 4. Measurement characteristics 4.1 The appearance and structure of the testing machine should be intact. The testing machine should have a nameplate, manufacturer's name, model, factory serial number and date, and a certificate of conformity, etc. 4.2 The temperature cold bath equipment can be maintained at (–20 ± 0.5) °C. 6. Calibration items and calibration methods 6.1 Appearance: Conduct an appearance inspection of the asphalt wax content measuring instrument in accordance with the measurement performance requirements in Section 4.1. 6.2 Temperature: Immerse the thermometer in the cold bath circular tank. After the temperature stabilizes, read the temperature every 2 minutes. After reading the temperature 10 times, take the arithmetic average value as the calibration result of the temperature. Take half the difference between the maximum and minimum values of the measurement results as the temperature fluctuation degree.
