5.1 Thermomechanical analyzers are employed in their various modes of operation (penetration, expansion, flexure, etc.) to characterize a wide range of materials. In most cases, the value to be assigned in thermomechanical measurements is the temperature of the transition (or event) under study. Therefore, the temperature axis (abscissa) of all TMA thermal curves must be accurately calibrated either by direct reading of a temperature sensor or by adjusting the programmer temperature to match the actual temperature over the temperature range of interest. 1.1 This test method describes the temperature calibration of thermomechanical analyzers from8201;−50 to 1500°C. (See Note 1.) 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard is similar to ISO 11359–1 but addresses a larger temperature range and utilizes additional calibration materials. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 7 and Note 11.

5.1 Dynamic mechanical analyzers monitor changes in the viscoelastic properties of a material as a function of temperature and frequency, providing a means to quantify these changes. In most cases, the value to be assigned is the temperature of the transition (or event) under study. Therefore, the temperature axis (abscissa) of all DMA thermal curves must be accurately calibrated by adjusting the apparent temperature scale to match the actual temperature over the temperature range of interest. 1.1 These test methods describes the temperature calibration of dynamic mechanical analyzers (DMA) from –100°C to 300°C. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Note 10.

This standard contains the manufacturing tolerances for both noble and base metal thermocouples manufactured in accordance with e.m.f.-temperature relationships of Part 1 of the standard. The tolerance values are for a thermocouple manufactured from wires, normally in the diameter range 0.25 mm to 3 mm, as delivered to the user and do not allow for calibration d rift during use.

This standard specifies the requirements and temperature/resistance relationship for industrial platinum resistance temperature sensors later referred to as “platinum resistors” or "resistors" and industrial platinum resistance thermometers later referred to as "thermometers" whose electrical resistance is a defined function of temperature. The International Standard applies to platinum resistors whose temperature coefficient α, defined as 0 100 C 100 0 ⋅ ° − = R R R α is conventionally written as α = 3.851 x 10–3 °C–1, where R100 is the resistance at t = 100 °C and R0 is the resistance at t = 0 °C. Values of temperature in this standard are in terms of the International Temperature Scale of 1990, ITS-90. Temperatures in degrees Celsius are denoted by the symbol t, except in Table 1 where the full nomenclature t90/°C is used. The standard covers resistors or thermometers for all or part of the temperature range -200 °C to +850 °C with different tolerance classes, which may cover restricted temperature ranges.

This International Standard establishes the requirements for mineral insulated thermocouple cables and for mineral insulated thermocouples but does not specify cold end seals, terminations, connections and other accessories. This standard deals only with cables and thermocouples having one pair of base-metal conductors and is intended for use in general industrial applications. NOTES 1 This standard does not deal with precious metal cables and thermocouples. 2 Mineral insulated cables and thermocouples also are available with more than one pair of conductors or where there is one conductor and a sheath. In these cases the detailed prescriptions in this standard — e.g. the dimensions — may not necessarily apply. 3 The special requirements for nuclear primary loop applications are dealt with in other standards.

The standard describes significant influences on the precision of measurements using radiation thermometers and explains their effects on a typical application. The procedure for choosing a suitable wavelength range for contact-free temperature measurements is described. The emissivity of important materials are summed up in a table. The influence of the object temperature, the dimension of the measurement field, and the setting time on the temperature resolution reachable are discussed.

It specifies manufacturing tolerances for extension and compensating cables (other than mineral insulated cables) provided directly to users of industrial processes. These tolerances are determined with respect to the e.m.f.-temperature relationship of Part 1 of the standard. Furthermore, requirements for extension and compensating cables for use in industrial process control are specified. The main technical changes with regard to the previous edition are as follows: Addition of Subclause 5.4 Connectors. Addition of Clauses 7 Dimensions and 8 Requirements.

IEC 60584-1:2013 specifies reference functions and tolerances for letter-designated thermocouples (Types R, S, B, J, T, E, K, N, C and A). Temperatures are expressed in degrees Celsius based on the International Temperature Scale of 1990, ITS-90 (symbol t90), and the EMF (symbol E) is in microvolts. The reference functions are polynomials which express the EMF, E in V, as a function of temperature t90 in °C with the thermocouple reference junctions at 0 °C. Values of EMF at intervals of 1 °C are tabulated in Annex A. This third edition cancels and replaces the second edition published in 1995 and constitutes a technical revision. It includes the following changes: - IEC 60584-1:1995 and IEC 60584-2:1982 have been merged; - the standard is now explicitly based on the reference polynomials which express thermocouple EMF as functions of temperature. The tables derived from the polynomials are given in Annex A; - inverse polynomials expressing temperature as functions of EMF are given in Annex B, but inverse tables are not given; - the range of the polynomial relating the EMF of Type K thermocouples is restricted to 1 300 °C; - values of the Seebeck coefficients are given at intervals of 10 °C; - thermoelectric data (EMF and Seebeck coefficients) are given at the fixed points of the ITS-90; - some guidance is given in Annex C regarding the upper temperature limits and environmental conditions of use for each thermocouple type.

1.1 This specification covers non-insulated platinum-rhodium alloys (weight percent composition), and platinum thermoelements that meet the requirement of Specification E230 and NIST Monograph 175.2 1.2 This specification does not cover platinum and platinum-rhodium materials, that require a higher purity than specified in 5.1, such as used for temperature coefficient of resistance (TCR) measurements or standards type calibration. For requirements of this superior quality, it is suggested that suppliers of precious metals be contacted. 1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
