This document specifies requirements for flat and long products of hot-rolled weldable fine-grain structural steels in the as-rolled (for SG grades only), normalized/normalized rolled and thermomechanical processed delivery conditions. It applies to steel plates rolled on a reversing mill, wide flats, hot-rolled sections and bars, which are intended for use in heavily loaded parts of welded or bolted structures. This document covers 13 grades and 6 qualities. Grades S275, S355, S390, S420, S460 and S500 are covered in Annex A. Grades SG245, SG290, SG325, SG345, SG365, SG415 and SG460 are covered in Annex B. Not all grades are available in all qualities, and some qualities have Charpy V-notch requirements. The steels specified in this document are applicable to hot-rolled plates, wide flats, sections and bars with a minimum nominal thickness of 3 mm and a maximum nominal thickness of 250 mm for grades S275N, S355N, S390N, S420N and S460N, a maximum nominal thickness of 150 mm for grades
Part 3 of this document, in addition to part 1, specifies requirements for flat and long products of hot rolled weldable fine grain structural steels in the normalized/normalized rolled delivery condition in the grades and qualities given in Tables 2 to 4 (chemical composition) and Tables 5 to 7 (mechanical properties) in thickness ≤250 mm for grades S275, S355 and S420 and in thickness ≤200 mm for grade S460.
Part 4 of this document, in addition to Part 1, specifies requirements for flat and long products of hot rolled weldable fine grain structural steels inTheThermomechanical rolled condition inThe grades and qualities given in Tables 2 to 4 (chemical composition) and Tables 5 to 7 (mechanical properties) in thickness ≤120 mm for flat products and in thickness ≤150 mm for long products.
This standard specifies requirements for flat and long products of hot rolled weldable fine grain structural steels in normalized/normalized rolled delivery condition.
This standard specifies requirements for flat and long products of hot rolled weldable fine grain structural steels in the thermomechanical rolled condition
This document specifies technical delivery conditions for flat and long products of hot rolled weldable fine grain structural steels in the normalized/normalized rolled delivery condition in the grades and qualities given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) in thickness less or equal 250 mm. The steels specified in this document are especially intended for use in heavily loaded parts of welded structures such as, bridges, flood gates, storages tanks, water supply tanks, etc., for service at ambient and low temperatures.
This British Standard gives recommendations and guidance for the design and construction of temporary and permanent barriers to be provided in and about buildings and places of assembly, such barriers being positioned and designed to protect persons from various hazards and to restrict or control the movement of persons or vehicles.This British Standard applies to:a) barriers that indicate routes;b) barriers capable of stopping or diverting moving vehicles within areas where vehicle speed is restricted to a maximum of 16 km/h (4.44 m/s, 10 mile/h);c) walls, glazing and other elements of buildings or structures where such elements act as protective barriers;d) areas other than spectator areas of sports halls and buildings used for spectator sports.This British Standard does not apply to:1) barriers for resisting impact from vehicles travelling at speeds greater than 16 km/h, e.g. bridge parapets beyond the curtilage of a building, or highway safety barriers (see BS 6779);2) barriers used in building operations and works of engineering construction;3) safety barriers, with or without opening gate features, for the protection of children up to 24 months, where the safety requirement is covered by a specific safety standard, e.g. BS EN 1930;4) permanent means of access to machinery (see BS EN ISO 14122, all parts);5) barriers used in spectator areas of sports halls, and buildings used for spectator sports (see BS EN 13200, all parts).
This document specifies the requirements and dimensions for lighting columns, brackets, base compartments, cableways and earthing terminals. It applies to post top columns not exceeding 20 m height for post top lanterns and columns with brackets not exceeding 18 m height for side entry lanterns.nThis Part does not attempt to restrict the actual appearance or shape of the column or bracket. The majority of lighting columns are normally of a stepped tubular, round, octagonal or polygonal cross-section. Lighting columns may be manufactured from materials other than those listed in the foreword (e.g. wood, plastic, cast iron) or in other forms (e.g. lattice and telescopic).nThis document specifies performance related to the essential requirements of resistance to horizontal (wind) loads and performance under vehicle impact (passive safety) in support of the Essential Requirement No 4 Safety in use measured according to the corresponding test methods included in this document or available in separate documents.
(1) EN 1993-1-10 contains design guidance for the selection of steel for fracture toughness and for through thickness properties of welded elements where there is a significant risk of lamellar tearing during fabrication.n(2) Section 2 applies to steel grades S 235 to S 690. However section 3 applies to steel grades S 235 to S 460 only.nNOTE EN 1993-1-1 is restricted to steels S235 to S460.n(3) The rules and guidance given in section 2 and 3 assume that the construction will be executed in accordance with EN 1090.

This European Standard provides guidance on where to find information on materials often used in temporary works. It draws attention to a number of points that a designer should take into account.nThe information given is limited to commonly used steel, aluminium alloys, cast iron, timber and timber based materials.nRequirements are also given for welding, for limiting corrosion and other deterioration.nIt is limited to the selection of types and grades of material from standards, which are either international or European Standards.
This draft European Standard covers the safety requirements regarding the storage and use of:n— liquefied pressurized ammonia for steam boiler plants;n— liquid ammonia water solution for the reduction of NOx in the flue gas from boiler plants. nAnnex A summarizes the operational aspects.
