E20.03 - Resistance Thermometers

SIGNIFICANCE AND USE
5.1 This guide is intended to be used for verifying the resistance-temperature relationship of industrial platinum resistance thermometers that are intended to satisfy the requirements of Specification E1137/E1137M. It is intended to provide a consistent method for calibration and uncertainty evaluation while still allowing the user some flexibility in the choice of apparatus and instrumentation. It is understood that the limits of uncertainty obtained depend in large part upon the apparatus and instrumentation used. Therefore, since this guide is not prescriptive in approach, it provides detailed instruction in uncertainty evaluation to accommodate the variety of apparatus and instrumentation that may be employed.  
5.2 This guide is intended primarily to satisfy applications requiring compliance to Specification E1137/E1137M. However, the techniques described may be appropriate for applications where more accurate calibrations are needed.  
5.3 Many applications require tolerances to be verified using a minimum test uncertainty ratio (TUR). This standard provides guidelines for evaluating uncertainties used to support TUR calculations.
SCOPE
1.1 This guide describes the techniques and apparatus required for the accuracy verification of industrial platinum resistance thermometers constructed in accordance with Specification E1137/E1137M and the evaluation of calibration uncertainties. The procedures described apply over the range of -200 °C to 650 °C.  
1.2 This guide does not intend to describe procedures necessary for the calibration of platinum resistance thermometers used as calibration standards or Standard Platinum Resistance Thermometers. Consequently, calibration of these types of instruments is outside the scope of this guide.  
1.3 Industrial platinum resistance thermometers are available in many styles and configurations. This guide does not purport to determine the suitability of any particular design, style, or configuration for calibration over a desired temperature range.  
1.4 The evaluation of uncertainties is based upon current international practices as described in JCGM 100:2008 “Evaluation of measurement data—Guide to the expression of uncertainty in measurement” and ANSI/NCSL Z540.2-1997 “U.S. Guide to the Expression of Uncertainty in Measurement.”  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
This guide is intended to be used by laboratories interested in the calibration of industrial platinum resistance thermometers that are intended to satisfy the requirements of Specification E 1137/E 1137M. It is intended to provide a consistent method for calibration and uncertainty evaluation while still allowing the user some flexibility in choice of apparatus and instrumentation. It is understood that the limits of uncertainty obtained depend in a large part upon the apparatus and instrumentation used. Therefore, since this guide is not prescriptive in approach, it provides detailed instruction in uncertainty evaluation to accommodate the variety of apparatus and instrumentation that may be employed.
This guide is intended primarily to satisfy applications requiring compliance to Specification E 1137/E 1137M. However, the techniques described may be appropriate in applications where higher accuracy calibrations are needed.
SCOPE
1.1 This guide describes the techniques and apparatus required for the accuracy verification of industrial platinum resistance thermometers constructed in accordance with Specification E 1137/E 1137M and the evaluation of calibration uncertainties. The procedures described apply over the range of –200 °C to 650 °C.
1.2 This guide is not intended to describe the procedures necessary for the calibration of platinum resistance thermometers intended to be used as calibration standards or Standard Platinum Resistance Thermometers. Consequently, calibration of these types of instruments is outside the scope of this guide.
1.3 Industrial platinum resistance thermometers are available in many styles and configurations. This guide does not purport to determine the suitability of any particular design, style, or configuration for calibration over a desired temperature range.
1.4 The evaluation of uncertainties is based upon current international practices as described in ISO/TAG 4/WG 3 “Guide to the Evaluation of Uncertainty in Measurement” and ANSI/NCSL Z540-2-1997 “U.S. Guide to the Expression of Uncertainty in Measurement”.

SIGNIFICANCE AND USE
These test methods provide uniform methods for testing industrial resistance thermometers so that a given tester may expect to obtain the same value of a test result from making successive measurements on the same test article within the limits of repeatability given in Appendix X4. Independent testers may also expect to obtain the same result from the testing of the same article within the limits of reproducibility given in Appendix X4.
These tests may be used to qualify platinum resistance thermometers for use in specific applications to meet a particular specification such as Specification E 1137/E 1137M, or to evaluate relative merits of equivalent test articles supplied by one or more manufacturers, or to determine the limits of the application of a particular design of thermometer.  
The expected repeatability and reproducibility of selected test methods are included in Appendix X4.
Some non-destructive tests described in these test methods may be applied to thermometers that can be subsequently sold or used; other destructive tests may preclude the sale or use of the test article because of damage that the test may produce.
SCOPE
1.1 These test methods cover the principles, apparatus, and procedures for calibration and testing of industrial resistance thermometers.
1.2 These test methods cover the tests for insulation resistance, calibration, immersion error, pressure effects, thermal response time, vibration effect, mechanical shock, self-heating effect, stability, thermoelectric effect, humidity, thermal hysteresis, thermal shock, and end seal integrity.
1.3 These test methods are not necessarily intended for, recommended to be performed on, or appropriate for every type of thermometer. The expected repeatability and reproducibility of the results are tabulated in .
1.4 These test methods, when specified in a procurement document, shall govern the method of testing the resistance thermometer.
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.

ABSTRACT
This specification establishes the physical, performance, and testing requirements, as well as resistance-temperature relationship and tolerances for metal-sheathed industrial platinum resistance thermometers (PRT) suitable for direct immersion temperature measurement. All materials including the sheath materials, sensing elements, insulation, connecting wire end closure materials, epoxy materials, and connecting wires shall be in accordance with specified requirements. The PRT shall be subjected to corresponding qualification tests to demonstrate conformance to the acceptance criteria of the following properties: insulation resistance; resistance versus temperature; minimum immersion length; pressure; thermal response time; vibration; self-heating; stability; thermoelectric effect; mechanical shock; and dimensions.
