This document is applicable to helical steel suspension springs used in the suspension of rail vehicles. It deals specially with cylindrical compression springs made from round section steel bars of constant diameter and with constant inclination of coiling. It deals also with helical springs with different shapes (e.g. conical and/or inclination of coiling not constant and/or steel bar with other cross sections, etc.). This document gives guidance for: specification of technical and quality requirements; — the approval procedure and quality assurance of production methods; — the examinations and tests to be carried out; — the delivery conditions.

 

This document defines the generic names and specific names used to designate the different categories of man-made fibres, based on a main polymer, currently manufactured on an industrial scale for textile and other purposes, together with distinguishing attributes that characterize them. The term “man-made fibres” has been adopted for those fibres obtained by a manufacturing process, as distinct from materials which occur naturally in fibrous form. This document gives recommendations of rules for the creation of the generic name (see Annex A). NOTE These rules have been introduced in the sixth edition of ISO 2076, and thus, they are not applicable to the existing generic names of the previous editions.

This document specifies the content and structure of specifications for research and test reactors, including sections relevant to radioactive waste management, spent fuel management, and decommissioning considerations for existing and new fission research reactors. It identifies the organizational, technical, and procedural elements that support the pre-decommissioning preparatory phase and associated operational interfaces. The scope includes guidance on defining decommissioning tasks, characterizing waste streams, and establishing administrative and operational arrangements that support safe and effective decommissioning. Considerations related to organizational capacity, turnover of research personnel, and the development of safety and safeguards competencies are addressed where relevant. The document also provides guidance on needs-based waste management pathways applicable to research reactors located on open or publicly accessible campuses or research centres. Safety and protection considerations addressed in this document include administrative and operational controls, as well as waste management and storage arrangements associated with decommissioning activities in areas with varying levels of access control. While many waste-management and decommissioning principles are common across nuclear facilities, this document applies these principles specifically to research and test reactors, reflecting their operational characteristics, scale, and regulatory context.

This document defines the overall requirements and architecture for the communication system used to fuel gaseous hydrogen Vehicles. Since this document precedes industry applications it is written in the context of anticipated use. Specific systems may be given as examples, but applying the communication protocol is not limited to a particular system. The document includes requirements for the hardware, software, identification of Vehicle, communication structure, and integrity of the data. The communication protocol is intended to be capable of: Exchange of data for identifying the vehicle Exchange of data for the relevant parameters of its VFS Exchange of data for optimizing fuelling protocol Exchange of data in a safe and reliable manner This version of ISO 19885-2 does not include communications not directly related to the fuelling of Vehicle, such as payment methods. This document is intended to be used in conjunction with the family of ISO 19885 documents. It takes the general fuelling protocol requirements in ISO 19885-1 and adds communication specific requirements which would apply to all communications systems used in hydrogen fuelling. Example physical layers are included in the annex to provide guidance. Additional editions of ISO 19885 (e.g. 19885-3) will use this ISO 19885-2 to specify their communication systems for each fuelling protocol within their document.

ISO 21813 specifies methods for the chemical analysis of fine high purity barium titanate powders used as the raw material for fine ceramics. ISO 21813 stipulates the determination methods of the barium, titanium, aluminium, cadmium, calcium, cobalt, dysprosium, iron, lead, magnesium, manganese, nickel, niobium, potassium, silicon, sodium, strontium, vanadium, zirconium, carbon, oxygen and nitrogen contents in high purity barium titanate powders. The barium and titanium contents, the major elements, are determined by using an acid decomposition-gravimetric method or an acid decomposition-inductively coupled plasma-optical emission spectrometry (ICP-OES) method. The aluminium, cadmium, calcium, chromium, cobalt, dysprosium, iron, lead, magnesium, manganese, nickel, niobium, potassium, silicon, strontium, vanadium and zirconium contents are simultaneously determined via an acid digestion-ICP-OES method. The nitrogen content is determined by using an inert gas fusion-thermal conductivity method, while that of oxygen is determined via an inert gas fusion-IR absorption spectrometry method. Finally, the carbon content is determined using a combustion-IR absorption spectrometry method or a combustion-conductometry method.

 

This document specifies tolerances on dimensions and shape for hot rolled uncoated narrow strip and cut lengths of non-alloy and alloy steel grades in accordance with Table 1. It is usually produced in thickness of 0,8 mm up to and including 16 mm and generally has a rolled width less than 600 mm but is also produced in rolled widths up to and including 720 mm. Hot-rolled narrow strip has a symmetrical thickness profile with tight crown tolerances and therefore cannot be compared to slit wide strip. This document also applies to hot-rolled strip for cold rolling. Table 1 — Field of application [...table not represented...] This document can also be used for other steels, e.g.: steels from standards not mentioned in Table 1. This document does not apply to: — continuously hot-rolled wide strip and plate/sheet cut from wide strip of non-alloy and alloy steels and narrow strip obtained by slitting wide strip (EN 10051); — hot-rolled patterned steel strip and plate/sheet cut from wide strip (see EN 10363); — uncoated or electrolytically coated cold rolled sheet and strip (see EN 10131); — hot-dip coated steel sheet and strip (EN 10143).

NOTE Actions for design during execution include those that only arise from execution activities and act during execution, termed construction actions (for example personnel and hand tools, auxiliary structures, equipment and elements used during execution), and others that are present during the service life of the completed structure (for example self-weight, wind, etc.) but which can act differently and/or have different values during execution. (2) prEN 1991-1-6 provides guidance and general rules for the determination of actions for the design of auxiliary structures, elements and equipment used during execution in case they are designed to the Eurocodes and not to other European Standards. NOTE Other European Standards (e.g. EN 12810, EN 12811, EN 12812) provide specific rules for certain types of auxiliary structures, equipment and elements used during execution. (3) prEN 1991-1-6 gives rules for buildings and bridges during execution to supplement the provisions in EN 1990. NOTE For combination rules for execution, see EN 1990. 1.2 Assumptions (1) The general assumptions given in EN 1990 apply. (2) The application of this document follows the limit state principle and is based on the partial factor method, unless explicitly prescribed differently. (3) The verification of buildings and civil engineering structures in transient design situations is undertaken in accordance with the Eurocodes, accounting for the interaction with any auxiliary structures, elements and/or equipment. (4) When using European product standards covering auxiliary structures, equipment and elements used during execution, it is assumed that the design basis, design requirements and, if provided, the safety and operational design limits specified in these product standards are taken into account. (5) Adequate planning, documentation, communication, control and supervision are provided during execution, involving all relevant parties. NOTE Execution of a structure can involve interaction between several parties from diverse engineering fields, responsible for the design, fabrication, transportation and execution of different subsystems used during the execution of a structure.
