Clinical dosimetry -- Dosimetry with solid thermoluminescence detectors for photon and electron radiations in radiotherapy
This document describes rules for the procedures, applications, and systems of thermoluminescence dosimetry (TLD) for dose measurements according to the probe method. It is particularly applicable to solid "TL detectors", i.e. rods, chips, and microcubes, made from LiF:Mg,Ti or LiF:Mg,Cu,P in crystalline or polycrystalline form. It is not applicable to LiF powders because their use requires special procedures. The probe method encompasses the arrangement, particularly in a water phantom or in a tissue-equivalent phantom, of single TL detectors or of "TL probes", i.e. sets of TL detectors arranged in thin-walled polymethyl methacrylate (PMMA) casings. The purpose of these rules is to guarantee the reliability and the accuracy indispensable in clinical dosimetry when applied on or in the patient or phantom. This document applies to dosimetry in teletherapy with both photon radiation from 20 keV to 50 MeV and electron radiation from 4 MeV to 25 MeV, as well as in brachytherapy with photon-emitting radionuclides. These applications are complementary to the use of ionization chambers.

Ergonomics of human-system interaction -- Part 210: Human-centred design for interactive systems
This document provides requirements and recommendations for human-centred design principles and activities throughout the life cycle of computer-based interactive systems. It is intended to be used by those managing design processes, and is concerned with ways in which both hardware and software components of interactive systems can enhance human?system interaction. NOTE Computer-based interactive systems vary in scale and complexity. Examples include off-the-shelf (shrink-wrap) software products, custom office systems, process control systems, automated banking systems, Web sites and applications, and consumer products such as vending machines, mobile phones and digital television. Throughout this document, such systems are generally referred to as products, systems or services although, for simplicity, sometimes only one term is used. This document provides an overview of human-centred design activities. It does not provide detailed coverage of the methods and techniques required for human-centred design, nor does it address health or safety aspects in detail. Although it addresses the planning and management of human-centred design, it does not address all aspects of project management. The information in this document is intended for use by those responsible for planning and managing projects that design and develop interactive systems. It therefore addresses technical human factors and ergonomics issues only to the extent necessary to allow such individuals to understand their relevance and importance in the design process as a whole. It also provides a framework for human factors and usability professionals involved in human-centred design. Detailed human factors/ergonomics, usability and accessibility issues are dealt with more fully in a number of standards including other parts of ISO 9241 (see Annex A) and ISO 6385, which sets out the broad principles of ergonomics. The requirements and recommendations in this document can benefit all parties involved in human-centred design and development. Annex B provides a checklist that can be used to support claims of conformance with this document.

Live working - Protective clothing against the thermal hazards of an electric arc - Part 1-1: Test methods - Method 1: Determination of the arc rating (ELIM, ATPV and/or EBT) of clothing materials and of protective clothing using an open arc
IEC 61482-1-1:2019 specifies test method procedures to determine the arc rating of flame resistant clothing materials and garments or assemblies of garments intended for use in clothing for workers if there is an electric arc hazard. An open arc under controlled laboratory conditions is used to determine the values of ELIM, ATPV or EBT of materials, garments or assemblies of garments. NOTE 1 The user can, if he desires, classify the arc protective performance into arc rating protection levels based on ELIM, ATPV and/or EBT values which correspond best to the different hazard and risks levels that can result from the user’s risk analysis. NOTE 2 This document is not dedicated to classifying the arc protective performance of the material and clothing into arc protection classes. Procedures determining these arc protection classes APC1 and APC2 are specified in IEC 61482 1-2, which uses a constrained arc for testing. NOTE 3 This test method is not intended and not appropriate to evaluate whether materials or garments are flame resistant or not, as this is covered in IEC 61482-2. Other effects than the thermal effects of an electric arc like noise, light emissions, pressure rise, hot oil, electric shock, the consequences of physical and mental shock or toxic influences are not covered by this document. Protective clothing for work intentionally using an electric arc, e.g. arc welding, plasma torch, is not covered by this document.
This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – addition of the Incident energy limit (ELIM) as a further arc rating performance property value; – replacement of char length requirement in the scope by indication that Procedure A is applicable for testing of materials meeting the limited flame spread requirements of IEC 61482-2; – clarification of the definition and the meaning of the Stoll curve; – modification of specification of positioning of monitor sensors with respect to the electric arc as function of intended high incident energy exposure of test specimens; – modification of specifications of monitor sensor construction; – specification of black paint; – elimination of calorimeters from the chest of the mannequin; – specification for possible positioning of mannequin(s) at a height different from the centre of the electric arc and possible turning in order to adequately expose all parts of the garment or clothing which would affect performance; – more explicit description of requirements for data acquisition system; – preconditioning of the samples; – modification of requirements for apparatus and arc exposure verification by bare shots; – more explicit description of test procedures A and B, in particular the subclauses dealing with “sequence of test”, “test parameter” and “test criteria”; – addition of determination of arc rating values of garments and/or garment assemblies.

Acoustics - Reference zero for the calibration of audiometric equipment - Part 7: Reference threshold of hearing under free-field and diffuse-field listening conditions (ISO/DIS 389-7:2019)
This document specifies a reference threshold of hearing for the calibration of audiometric equipment used under the following conditions. a) The sound field in the absence of the listener consists of either a free progressive plane wave (free field) or a diffuse sound field, as specified in ISO 8253-2. In the case of a free field, the source of sound is directly in front of the listener (frontal incidence). b) The sound signals are pure (sinusoidal) tones in the case of free field conditions and one third octave bands of (white or pink) noise in the case of diffuse field conditions. c) The sound pressure level is measured in the absence of the listener at the position where the centre of the listener’s head would be. d) Listening is binaural. NOTE 1 Correction values for the threshold of hearing under free-field listening conditions and selected angles of sound incidence (45° and 90°) deviating from frontal incidence are given in ISO 8253-2 for information. NOTE 2 Other conditions are given in Reference [1]. The data are given in numerical form for the preferred frequencies in the one-third-octave series from 20 Hz to 16 000 Hz inclusive in accordance with ISO 266 and, in addition, for some intermediate audiometric frequencies up to 18 000 Hz. The threshold data differ from the audiometric zero specified in ISO 389-1, ISO 389-2, ISO 389-5 and ISO 389-8, since the latter refer to monaural listening through earphones with sound pressure levels referred to specified couplers and ear simulators. Direct comparison between the data in the parts of ISO 389 mentioned above and in this document is therefore not appropriate.

The required withstand voltage and minimum approach distances determined by the method described in this standard are recommended for use only if the following working conditions prevail: – workers are trained for, and skilled in, working live lines or close to live conductors or equipment; – the operating conditions are adjusted so that the statistical overvoltage does not exceed the value selected for the determination of the required withstand voltage; – transient overvoltages are the determining overvoltages; – tool insulation has no continuous film of moisture present on the surface; – no lightning is observed within 10 km of the work site; – allowance is made for the effect of conducting components of tools; NOTE 1 In some countries, special procedures have been developed to permit live working with surface moisture on tools at distribution voltages (below 50 kV).

Alarm systems - Intrusion and hold-up systems - Part 2-4: Requirements for combined passive infrared and microwave detectors
This document is for combined passive infrared and microwave detectors installed in buildings and provides for security Grades 1 to 4 (see EN 50131-1), specific or non-specific wired or wire-free detectors, and uses environmental classes I to IV (see EN 50130-5). This document does not include requirements for detectors intended for use outdoors. The purpose of the detector is to detect the broad spectrum infrared radiation emitted by an intruder, to emit microwave signals and analyse the signals that are returned and to provide the necessary range of signals or messages to be used by the rest of the intrusion alarm system. For a combined detector where both technologies have to be activated in order to generate an alarm condition, providing higher false alarm immunity, it is essential to meet the grade dependent requirements of this document. For a combined detector which can be configured or operated such that each detection technology can generate an alarm condition independently, it is essential to meet the grade-dependant requirements of EN 50131-2-2 and EN 50131-2-3 when configured accordingly. Otherwise the manufacturer clearly states that the detector does not comply to this document and not to EN 50131-2-2 and EN 50131-2-3 when put into such a configuration. It is essential that a detector fulfil all the requirements of the specified grade. Functions additional to the mandatory functions specified in this document can be included in the detector, providing they do not influence the correct operation of the mandatory functions. This document does not apply to system interconnections.
