This document specifies requirements for weldable structural steels made of hot finished seamless and high frequency welded hollow sections to be used in the fabrication of fixed offshore structures. The following thickness limitations are given in this standard: - for seamless hollow sections up to and including 65 mm; - for HFW hollow sections up to and including 25,4 mm. Greater thicknesses can be agreed, provided the technical requirements of this European Standard are maintained. This European Standard is applicable to steels for offshore structures, designed to operate in the offshore sector but not to steels supplied for the fabrication of subsea pipelines, risers, process equipment, process piping and other utilities. It is primarily applicable to the North Sea Sector, but may also be applicable in other areas provided that due consideration is given to local conditions e.g. design temperature. NOTE This document has an informative Annex E on the prequalification of steels for fixed offshore structures in arctic areas. Minimum yield strengths up to 770 MPa are specified together with impact properties at temperatures down to -40 °C.

This document specifies technical delivery conditions for flat products of high yield strength alloy special steels. The grades and qualities are given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) and are supplied in the quenched and tempered condition. The steels specified in this document are applicable to hot-rolled flat products with a minimum nominal thickness of 3 mm and a maximum nominal thickness of 200 mm for grades S460, S500, S550, S620 and S690, a maximum nominal thickness of 125 mm for grades S890 and S960, in steels which, after quenching and tempering, have a specified minimum yield strength of 460 MPa to 960 MPa.

This document defines the minimum requirements for treatment systems, which generate the active substance - "Active chlorine" - from sodium chloride by electrolysis for on-site (in-situ) operation. The in-situ generated active substance (IGAS), in this case active chlorine, may be put into a solution ("off-line") or directly generated in the pipes ("in-line"). This document specifies the device construction, and test methods for the equipment used for in-situ generation of active chlorine. It specifies requirements for instructions for installation, operation, maintenance, safety and for documentation to be provided with the product. The in-situ generation of active substances and the placing of their precursors on the EU market are subject to the specifications of the Biocidal Products Regulation (EU) 528/2012 ["Biocidal products"]). Active substances, generated by devices, which are claiming compliance with this document, shall comply with the BPR for both the registered active chlorine, quality standards and the precursor in accordance with appropriate application and "Product Type" as listed in the BPR. This standard does not identify applications for in situ devices for generation of active chlorine. The range of applications for in-situ generation of chlorine is diverse. It is the responsibility of the economic operator/product supplier, claiming compliance with this standard, to identify the appropriate system type and operating conditions for the specific application and to: - specify the quality of the biocide appropriate to the application. This may be defined in national or international standards; - specify the appropriate product type (see Clause 7) and operating conditions (concentration, dosage rate and quality of the active chlorine); - specify any other regulatory requirements relevant to the specific application; - specify the appropriate precursor sodium chloride (natural or artificial brine), for the application; - and to label the product accordingly.

This document specifies the safety requirements for walkways and working places on inland navigation vessels in the areas used for work. Walkways in the passenger area are governed by requirements which are outside the scope of this standard. Requirements related to the marking of safety and health protection are not covered by this standard.

This document indicates the minimum training and registration requirements for post-tensioning personnel involved in the installation of post-tensioning kits in concrete structures using bonded or unbonded tendons in accordance with the relevant execution specifications, product standard and/or European Technical Assessment (ETA) contract specification. A CEN technical standard does not deal with contracts, but the specification (in this case the execution specification). This document describes the tasks that the various categories of post-tensioning personnel can undertake. For the purposes of this document, post-tensioning personnel means: (Site-)Manager, Supervisors, Operatives and Trainees who are directly or indirectly employed on a sub-contract basis. This document does not cover safety and health aspects. This document does not cover contractual issues. Part 2 of this standard deals with the assessment of competence. Note: It is within the concept of this standard that supplementing requirements can be given in the execution specification or in a national annex.

This European Standard specifies the characteristics and the requirements for sulfamic acids and salts. Similar to antiscalants as phosphonic acids and its salts (EN 15040) and polycarboxylates and its salts (EN 15039), sulfamic acid and its salts can be used alone or in combination with others drinking water substances as antifoulants (antiscalant effect) for membranes for the treatment of water intended for human consumption. Sulfamic acid and salts are used in mixtures with sodium hydroxide and sodium hypochlorite or other drinking water chlorine based oxidizing agents as biofilm remover especially for reverse osmosis (RO) and nanofiltration membranes to prevent biofouling by microbiological contamination. The components will not pass the membrane and are rejected to the wastewater with the concentrate. For the other components EN standards are already exist.

This document specifies technical delivery conditions for flat and long products of hot rolled weldable fine grain structural steels in the thermomechanical rolled condition in the grades and qualities given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) in thickness ≤ 150 mm. The steels specified in this document are especially intended for use in heavily loaded parts of welded structures such as, bridges, flood gates, storage tanks, water supply tanks, etc., for service at ambient and low temperatures.

This document specifies a test method for the determination of cetane numbers (“CN”) in diesel fuel, using a standard single cylinder, four-stroke cycle, indirect injection engine. The cetane number provides a measure of the ignition characteristics of diesel fuels in compression ignition engines. The cetane number is determined at constant speed in a compression ignition test engine equipped with a swirl chamber. The cetane number scale covers the range from zero to 100, but typical testing is performed in the range from about 40 CN to about 75 CN. The precision of this test method covers the range from 44 CN to about 66 CN. This document is applicable to distillate as well as paraffinic diesel fuels intended for use in diesel engines, including those containing fatty-acid methyl esters (FAME), ignition-improvers or other diesel fuel additives. This engine test procedure may be used for other fuels such as synthetics and vegetable oils. However, samples with fuel properties that interfere with the gravity-based pre-supply pressure to the fuel pump e.g. due to high viscosity can only be used to a limited extent. Precision data for such fuels are not available at this stage. Precision data for paraffinic diesel fuels are currently under development.
