This document provides general methods for measurement and calculation of quantities associated with human exposure to electromagnetic fields in the frequency range from 0 Hz to 300 GHz. It is intended specifically to be used for the assessment of emissions from products and comparison of these with the exposure limits for the general public given in Council Recommendation 1999/519/EC, and those given for workers in Directive 2013/35/EU, as appropriate. It also is intended to be used for assessment of human exposure to electromagnetic fields in the workplace to determine compliance with the requirements of Directive 2013/35/EU. This standard deals with quantities that can be measured or calculated external to the body, notably electric and magnetic field strength or power density, and includes the measurement and calculation of quantities inside the body that form the basis for protection guidelines. In particular the standard provides information on: — definitions and terminology, — characteristics of electromagnetic fields, — measurement of exposure quantities, — instrumentation requirements, — methods of calibration, — measurement techniques and procedures for evaluating exposure, — calculation methods for exposure assessment. Where an applicable electromagnetic field standard specific to a product or technology exists it is expected to be used rather than this document. EN 62311:—, Table 1 gives a list of relevant standards.

This International Standard specifies the requirements, in addition to the resistance versus
temperature relationship, for both industrial platinum resistance thermometers (later referred to
as "thermometers") and industrial platinum resistance temperature sensors (later referred to as
"platinum resistors") whose electrical resistance is derived from defined functions of
temperature.
Values of temperature in this document are in terms of the International Temperature Scale of
1990, ITS-90. A temperature in the unit °C of this scale is denoted by the symbol t, except in
Table A.1 where the full nomenclature t90 /°C is used.
This document applies to platinum resistors whose temperature coefficient α, defined as
is conventionally written as α = 3,851⋅10-3 °C-1, where R100 is the resistance at t = 100 °C and R0 is the resistance at t = 0 °C.
This document covers platinum resistors and thermometers for the temperature range −200 °C
to +850 °C with different tolerance classes. It can also cover particular platinum resistors or
thermometers for a part of this temperature range.
For resistance versus temperature relationships with uncertainties less than 0,1 °C, which are
possible only for platinum resistors or thermometers with exceptionally high stability and
individual calibration, a more complex interpolation equation than is presented in this document
can be necessary. The specification of such equations is outside the scope of this document.

It is necessary for thermocouple temperature measurement that the electro-motive force (abbreviated
as e.m.f. hereafter) of the thermocouple circuit is precisely measured by a measuring
instrument. A thermocouple is electrically connected to the instrument by a proper pair of
electric cables. IEC 60584-3 standardizes these cables. It specifies identification and manufacturing
tolerances for extension and compensating cables (mineral insulated extension and
compensating cables are not included) provided directly to users of industrial processes.
These tolerances are determined with respect to the e.m.f. versus temperature relationship of
IEC 60584-1. The requirements for extension and compensating cables for use in industrial
process control are specified.
Extension and compensating cables may consist of a single strand (solid) wire or multistranded
wire for which this document is applied. Specification for extension and compensating
conductors of forms of rods, flat wires or strips can be established by agreement between
suppliers and users.

IEC 62828-3:2018 establishes specific procedures for testing temperature transmitters used in measuring and control systems for industrial process and for machinery control systems. When the process measurement transmitter features the temperature transmitter separated from the sensing element, the standard applies only to the temperature transmitter without the sensing element. In the case of a device where the sensing element is fully integrated with the temperature transmitter, the standard applies to the complete device. For general test procedures, reference is made to IEC 62828-1, which is applicable to all types of industrial and process measurement transmitters (PMT). The sensing element itself as well as radiation thermometers are excluded from the scope of this document. The IEC 62828 series cancels and replaces the IEC 60770 series and proposes revisions for the IEC 61298 series. NOTE In industrial and process applications to indicate the process measurement transmitters, it is common also to use the terms “industrial transmitters”, or “process transmitters”.

IEC 62828-3:2018 establishes specific procedures for testing temperature transmitters used in measuring and control systems for industrial process and for machinery control systems.
When the process measurement transmitter features the temperature transmitter separated from the sensing element, the standard applies only to the temperature transmitter without the sensing element. In the case of a device where the sensing element is fully integrated with the temperature transmitter, the standard applies to the complete device. For general test procedures, reference is made to IEC 62828-1, which is applicable to all types of industrial and process measurement transmitters (PMT). The sensing element itself as well as radiation thermometers are excluded from the scope of this document. The IEC 62828 series cancels and replaces the IEC 60770 series and proposes revisions for the IEC 61298 series.
NOTE In industrial and process applications to indicate the process measurement transmitters, it is common also to use the terms “industrial transmitters”, or “process transmitters”.

This part of IEC 61757 defines detail specifications for distributed temperature measurement
by a fibre optic sensor, also known as fibre optic distributed temperature sensing (DTS). DTS
includes the use of Raman scattering, Brillouin scattering and Rayleigh scattering effects. In
addition, Raman scattering and Rayleigh scattering based measurements are performed with
a single-ended fibre configuration only. Brillouin scattering based measurements are
performed with a single-ended fibre or fibre loop configuration. The technique accessible from
both sides at same time (e. g. Brillouin optical time domain analysis, BOTDA) is referred to
here as a loop configuration. Generic specifications for fibre optic sensors are defined in
IEC 61757-1:2012.
This part of IEC 61757 specifies the most important DTS performance parameters and defines
the procedures for their determination. In addition to the group of performance parameters, a
list of additional parameters has been defined to support the definition of the measurement
specifications and their associated test procedures. The definitions of these additional
parameters are provided for informational purposes and should be included with the sets of
performance parameters.
A general test setup is defined in which all parameters can be gathered through a set of tests.
The specific tests are described within the clause for each measurement parameter. This
general test setup is depicted and described in Clause 4 along with a list of general
information that should be documented based upon the specific DTS instrument and test
setup used to measure these parameters as per IEC 61757-2-2.
Annex A provides a blank performance parameter table which should be used to record the
performance parameter values for a given DTS instrument and chosen optical test setup
configuration.
Annex B provides guidelines for optional determination of point defect effects.

This International Standard establishes the requirements for simplex, duplex and triplex
mineral-insulated metal-sheathed thermocouple cables and thermocouples, which are intended
for use in general industrial applications. The abbreviation MIMS (for “mineral-insulated
metal-sheathed”) will be used hereafter. It covers thermocouple cables and thermocouples with
only base-metal conductors of Types T, J, E, K and N. The specifications in this standard apply
to new thermocouple cables and thermocouple units as delivered to the user. They do not apply
to the product after use.
External seals, terminations, connections and other accessories are not within the scope of this
International Standard.
This standard does not apply to precious metal thermocouple cables and thermocouples. The
special requirements for nuclear primary loop applications are dealt with in the other standards.

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.

IEC 61788-5:2013 covers a test method for the determination of copper to superconductor volume ratio of Cu/Nb-Ti composite superconducting wires. This test method and the alternate method in Annex are intended for use with Cu/Nb-Ti composite superconducting wires with a cross-sectional area of 0,1 mm2 to 3 mm2, a diameter of the Nb-Ti filament(s) of 2 micrometers to 200 micrometers, and a copper to superconductor volume ratio of 0,5 or more. The Cu/Nb-Ti composite test conductor discussed in this method has a monolithic structure with a round or rectangular cross-section. This test method is carried out by dissolving the copper with nitric acid. Deviations from this test method that are allowed for routine tests and other specific restrictions are given in this standard. Cu/Nb-Ti composite superconducting wires beyond the limits in the cross-sectional area, the filament diameter and the copper to superconductor volume ratio could be measured with this present method with an anticipated reduction of uncertainty. Other, more specialized, specimen test geometries may be more appropriate for conductors beyond the limits and have been omitted from this present standard for simplicity and to retain low uncertainty. The test method given in this standard is expected to apply to other superconducting composite wires after some appropriate modifications. The copper to superconductor volume ratio of composite superconductors is used mainly to calculate the critical current density of superconducting wires. The test with the method given in this International Standard may be used to provide part of the information needed to determine the suitability of a specific superconductor. Moreover, this method is useful for quality control, acceptance or research testing if the precautions given in this standard are observed. This second edition cancels and replaces the first edition published in 2000. It constitutes a technical revision. The main revisions are the addition of two new annexes, 'Uncertainty considerations' (Annex E) and 'Uncertainty evaluation in test method of copper to superconductor volume ratio of Cu/Nb-Ti composite superconductors' (Annex F).

This part of IEC 60584 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 μV, 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. For convenience of calculating temperatures, inverse functions are given in Annex B which express temperature as functions of EMF within stated accuracies. This International Standard specifies the tolerances for thermocouples manufactured in accordance with this standard. The tolerance values are for thermocouples manufactured from wires, normally in the diameter range 0,13 mm to 3,2 mm, as delivered to the user and do not allow for calibration drift during use. Annex C gives guidance on the selection of thermocouples with regard to temperature range and environmental conditions.
