This procedure is equivalent to the international document D24. Chapters 1, 2, 3, 4, and 6 and parts of Chapter 5 do not adopt Articles 5.5, 5.6, and 5.7.1 ScopeThis procedure is applicable to the full-radiation thermometer for working in the measurement range (20~2800) °C (hereinafter referred to as the full-radiation) The first test and subsequent verification of the thermometer and its sensors (optical systems and detectors).2 CitationsThis procedure refers to the following documents. OIMLD24TotalRadiationPyrometers1996 English version JJF1001-1998 General Terms and Definitions JJF1059-1999 "Measurement and Expression of Measurement Uncertainty" When using this procedure, care should be taken to use the current valid version of the above cited documents.3 terms and units of measure3.1 Terminology 3.1.1 inherent error The inherent error characterizes the accuracy of the full-radiation thermometer, which is equivalent to measuring the constant temperature of the full-radiation thermometer under the reference conditions. Between the indicated mean value of the blackbody radiation source temperature and the agreed true value of the blackbody temperature using a standard thermometer difference. 3.1.2 Target distance The distance between the optical system of the total radiation thermometer and the surface of the object to be measured, also called the measurement distance. 3.1.3 Target area The surface of the object to be measured is a part of the vertical projection plane of the optical axis of the target distance, and its image covers the full radiance temperature. The gauge detector (or field diaphragm) whose diameter determines the minimum size of the measured object corresponding to the target distance. 3.1.4 Target aperture The ratio of the diameter of the target area to the target distance (D/L) is inversely proportional to the distance coefficient. Can use distance and straight Path diagram or table representation. 3.2 Unit of measurement 3.2.1 The verification of the full radiation thermometer shall be based on the.1990 international temperature scale, and the output shall be expressed in units of the International System of Units. Degrees are expressed in degrees Celsius (°C) or Kelvin (K). 3.2.2 The temperature measurement result indicated by the output quantity can be directly read by the scale or display device of temperature. The number can also be the temperature calculation result using a table, formula or curve. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 67-2003_English be delivered?Answer: Upon your order, we will start to translate JJG 67-2003_English as soon as possible, and keep you informed of the progress.
