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:
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 document specifies the technical and functional characteristics for all types of thermometers (electronic, mechanical, etc.) for equipping the means used for the transport, storage and distribution of temperature sensitive goods and for measuring the ambient or internal temperature of the products between −80 °C and +85 °C.
It specifies the test methods which allow the verification of the equipment's conformity to suitability and performance requirements.
It applies to the whole thermometer and indicating device(s). The temperature sensor(s) can be integrated into the thermometer or remote from it (wired or wireless external temperature sensor(s)).
It does not specify the location of the thermometer and its sensors with respect to types of usage such as transport, storage and distribution.
NOTE Examples for the transport, storage and distribution of temperature sensitive goods between −80 °C and +85 °C include chilled, frozen, deep frozen and quick-frozen food; ice cream; fresh and hot food; pharmaceuticals; blood and organs; chemicals; biologicals; electronic and mechanical devices; flowers, plants and bulbs; raw materials and liquids; animals; art and furnishings.

This document specifies requirements and test methods for room temperature sensors used to control the room temperature.
This document is applicable to wall mounted and flush mounted room temperature sensors.
The following aspects are not covered by this document:
NOTE The measured value available at the output of the sensor is influenced by the place where the sensor device is located and factors such as air velocity, wall temperature, self/waste heating of the device and the air temperature. The perceived temperature, which is important for the well-being of a person, depends among other factors on air temperature, temperature of the surrounding walls and air flow rate as indicated in EN ISO 7730.
The temperature sensor element can be combined with other sensors in one device. This document only deals with the room temperature sensing of this devices. Other sensors are not covered except of their influence on the room temperature sensing (e.g. self-heating).
This document specifies sensor characteristics contributing to the determination of the control accuracy of individual zone controller according to EN 15500 1.

4.1 This guide describes a procedure for placing a water triple-point cell in service and for using it as a reference temperature in thermometer calibration.
4.2 The reference temperature attained is that of a fundamental state of pure water, the equilibrium between coexisting solid, liquid, and vapor phases.
4.3 The cell is subject to qualification but not to calibration. The cell may be qualified as capable of representing the fundamental state (see 4.2) by comparison with a bank of similar qualified cells of known history, and it may be so qualified and the qualification documented by its manufacturer.
4.4 The temperature to be attributed to a qualified water triple-point cell is exactly 273.16 K on the ITS-90, unless corrected for isotopic composition (refer to Appendix X3).
4.5 Continued accuracy of a qualified cell depends upon sustained physical integrity. This may be verified by techniques described in Section 6.
4.6 The commercially available triple point of water cells described in this standard are capable of achieving an expanded uncertainty (k=2) of between ±0.1 mK and ±0.05 mK, depending upon the method of preparation. Specified measurement procedures shall be followed to achieve these levels of uncertainty.
4.7 Commercially-available triple point of water cells of unknown isotopic composition should be capable of achieving an expanded uncertainty (k=2) of no greater than 0.25 mK, depending upon the actual isotopic composition (3). These types of cells are acceptable for use at this larger value of uncertainty.
1.1 This guide covers the nature of two commercial water triple-point cells (types A and B, see Fig. 1) and provides a method for preparing the cell to realize the water triple-point and calibrate thermometers. The qualifications concerning preparation and the types of glass used for a cell are discussed. Tests for assuring the integrity of a qualified cell and of cells yet to be qualified are given. Precautions for handling the cell to avoid breakage are also described.
