This document specifies load actions and load combinations for the calculation of load effects as basis for the proof of competence of a crane and its main components. It will be used together with the other generic parts of the EN 13001 series of standards, see Annex E. As such they specify conditions and requirements on design to prevent mechanical hazards of cranes and provide a method of verification of those requirements. NOTE Specific requirements for particular types of crane are given in the appropriate European product standards for the particular crane type, see Annex E. The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and reasonably foreseeable misuse. Clause 4 of this document provides means to reduce or eliminate the risks of mechanical failures due to the following: a) rigid body instability of the crane or its parts (tilting); b) exceeding the limits of strength (yield, ultimate, fatigue); c) elastic instability of the crane or its parts or components (buckling, bulging). The hazards covered by this document are identified by Annex G. This document is not applicable to cranes that are manufactured before the date of its publication as EN.

 

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 provides guidelines for establishing, maintaining, monitoring and improving infrastructure resilience to help ensure the continuity and robustness of essential services. It supports collaborative decision-making across many stakeholders in diverse organizations. It can be used for engaging stakeholders at all levels responsible for, or having influence on, infrastructure resilience matters. This document is intended to be applicable to all types and sizes of organizations which have a role in infrastructure resilience.

This document specifies the test principle, apparatus, materials, sampling, determination, calculation, and reporting requirements for the determination of particulate matter content in natural gas by a gravimetric method. Unless otherwise specified, the volume standard reference conditions used in this standard are 101,325 kPa and 273,15 K.

 

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 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 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 specifies methods for measuring rolling resistance, under controlled laboratory conditions, for new pneumatic tyres designed primarily for use on passenger cars, trucks and buses. This document is not applicable to tyres intended for temporary use only. It includes a method for correlating measurement results to allow inter-laboratory comparisons. It is designed to facilitate international cooperation and, possibly, regulation building. Measurement of tyres using the methods of this standard enables comparisons to be made between the rolling resistance of new test tyres when they are free-rolling straight ahead, in a position perpendicular to the drum outer surface, and in steady-state conditions. During the measurement of rolling resistance using the methods of this standard, the value of the rolling circumference of the tyre can be derived using the drum method of either standard ISO 9112 or ISO 17269.
