- Scope
1.1 These test methods describe the principles, apparatus, and procedures for calibration and testing of resistance thermometers.
1.2 These test methods cover definitions of terms and tests for insulation resistance, interchangeability, calibration, immersion error, pressure effects, thermal response time, vibration effect, mechanical shock, self-heating effect, stability, thermoelectric effect, humidity, and thermal hysteresis.
1.3 This series of tests is not necessarily intended nor recommended to be performed on every thermometer. Not all the tests are appropriate for all types of thermometers. The expected limits of results are given in the test procedures and also tabulated in Appendix X4.
1.4 The test methods, when specified in a procurement document, shall govern the method of testing the resistance thermometer and the accuracy of the tests.
1.5 Thermometer performance specifications, acceptance limits, and sampling methods are not covered in these test methods; they should be specified separately in the procurement document.
1.6 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 6.3.2, 6.3.5, and 8.1.
