This Technical Specification provides guidelines for the use of hydrogen in its gaseous and liquid forms as well as its storage in either of these or other forms (hydrides). It identifies the basic safety concerns, hazards and risks, and describes the properties of hydrogen that are relevant to safety. Detailed safety requirements associated with specific hydrogen applications are treated in separate International Standards. “Hydrogen” in this paper means normal hydrogen (1H2), not deuterium (2H2) or tritium (3H2).

 

This document specifies a specific method for determining the Vicat softening temperature (VST) of thermoplastics pipes and fittings. It includes the adaption of method B 50 of ISO 306:2022 using a force of 50 N and a heating rate of 50 °C/h and the procedure for specimen preparation. It includes the particular test conditions for determining the Vicat softening temperature (VST) of unplasticized poly(vinylchloride) (PVC-U) or chlorinated poly(vinylchloride) (PVC-C) pipes and fittings, for high impact resistance poly(vinylchloride) (PVC-HI) pipes and for acrylonitrile/butadiene/styrene (ABS) and acrylonitrile/styrene/acrylic ester (ASA) pipes and fittings. This document can also be used for pipes and fittings from other materials (e.g. PE-UHMW).

 

The method specified is based on determining the temperature at which a standard indenter, under a force of 50 N ± 1 N, penetrates 1 mm into the surface of a test piece cut from the wall of a pipe or fitting while the temperature is raised at a constant rate. Is applicable only to thermoplastics materials for which it is possible to measure the temperature at which the rate of softening becomes rapid. Is based on ISO 306:1994 which, however, applies to materials in the form of sheets.

This document specifies requirements, test methods and performance criteria for thermal image fire detectors (TIFD), which operate in the infrared spectrum, for use in fire detection and alarm systems installed in and around buildings (see ISO 7240-1). Detectors developed for the protection of specific risks that incorporate special characteristics (including additional features or enhanced functionality for which this document does not define a test or assessment method) are beyond the scope of this document.

 

This document specifies how a preliminary welding procedure specification is qualified by welding procedure tests according to the principles given in ISO 15607. This document applies to production welding, repair welding and build-up welding. This document defines the conditions for the execution of welding procedure qualification tests and the range of qualification for welding procedures for all practical welding operations within the qualification of this document. The primary purpose of welding procedure qualification is to demonstrate that the joining process proposed for construction is capable of producing welded joints having the required mechanical properties for the intended application. Two levels of welding procedure tests are given to permit application to a wide range of welded fabrications. They are designated by levels 1 and 2. For level 2 the extent of testing is greater, and the ranges of qualification are more restrictive than in level 1. Welding procedure qualification tests carried out to level 2 automatically qualify for level 1 requirements, but not vice-versa. When no level is specified in a contract or application standard, all the requirements of level 2 apply. This document applies to the arc and gas welding of steels in all product forms and the arc welding of nickel and nickel alloys in all product forms. Arc and gas welding are covered by the following processes in accordance with ISO 4063:2023. 111 — manual metal arc welding (metal-arc welding with covered electrode); 114 — self-shielded tubular-cored arc welding; 12 — submerged arc welding; 13 — gas-shielded metal arc welding; 14 — gas-shielded arc welding with non-consumable electrode; 15 — plasma arc welding; 311 — oxy-acetylene welding.

This document specifies the execution, validation, verification and documentation of a numerical welding simulation within the field of computational welding mechanics (CWM) and performed with a scientific computational tool (SCT). This document is applicable to the thermal and mechanical finite element analysis (FEA) of arc, laser and electron beam welding processes for the purpose of calculating the effects of welding processes, and in particular, residual stresses and distortion, in support of structural integrity assessment.

 

This document specifies a set of tests and procedures designed to indicate whether encoders or decoders meet the requirements specified in Rec. ITU-T H.266 | ISO/IEC 23090-3.

 

This document specifies a method for the determination of the selected metals and semi-metals migration from the internal surface of plastics pipes, fittings and joints to be used for the transport of water intended for human consumption by inductively coupled plasma mass spectrometry (ICP-MS). This document applies to the determination of the selected metal and semi-metals migration values of lead (Pb), tin (Sn), antimony (Sb), cadmium (Cd), chromium (Cr), copper (Cu), barium (Ba), magnesium (Mg), aluminium (Al), nickel (Ni), zinc (Zn) and arsenic (As). This method is suitable for all plastics pipes, fittings, and joints to be used for the transport of water and raw water intended for human consumption.

This document addresses the essential elements and protocols needed for Space Traffic Coordination (henceforth referred to as “STC”). STC is critical to enhance the safety, stability, and sustainability of operations in the space environment.” STC enables flight safety, mitigates collision risk (for manoeuvrable spacecraft), and mitigates Radio Frequency Interference (RFI) for all phases of flight, spanning pre-launch safety assessment through manoeuvre plans, on-orbit collision avoidance, RFI mitigation support services, and mission disposal. This document is designed to enable the effective coordination of space traffic from pre-launch safety assessment to disposal at the end of operation through norms, the effective monitoring, and mitigation of collision risk and RFI. The document is designed for state actors, spacecraft designers, spacecraft operators, and STC system developers and operators. While this document applies to the range of orbital regions in which current STC and SSA systems can effectively track, monitor, and provide actionable data for space objects, it is envisioned that this document is generally applicable to all orbit regimes and for orbits around all central bodies and barycentres.

This document concerns human exposure to whole-body vibration and shock in buildings with respect to the comfort and annoyance of the occupants based on both measurements and simulations. It specifies a method for measurement and evaluation, comprising the determination of the measurement direction and measurement location. It defines in Annex A the frequency weighting Wm which is applicable in the frequency range 1 Hz to 80 Hz where the posture of an occupant does not need to be defined. Whilst it is often the case that a building will be available for experimental investigation, many of the concepts contained within this document would apply equally to a building in the design process or where it will not be possible to gain access to an existing building. In these cases, reliance will have to be placed on the prediction of the building response by some means. This document does not provide guidance on the likelihood of structural damage, which is discussed in ISO 4866[3]. Further, it is not applicable to the evaluation of effects on human health and safety. Acceptable magnitudes of vibration are not stated in this document, but guidance is provided in Annex C in the form of exposure-response curves for the estimation of annoyance when vibration originates from various sources, including railway, construction activities and blasting.
