Overview: This standard has been updated and the newly-amended edition is ready for purchase. It is an indispensable guide to those who specify, purchase or supply steel, of the standard purchase specifications and delivery conditions for circular non-alloy steel tubes suitable for welding and threading and provides a number of options for the finish of tube ends and coatings. The Amendment was produced in order to fulfil the requirements of the EC mandate M/131 belonging to Construction Product Directive 89/106/EC. The scope of BS EN 10255:2004 has not changed.This document covers tubes of specified outside diameter 10,2 mm to 165,1 mm (thread size 1/8 to 6) in two series, medium and heavy, and three types of designated thicknesses. This essential amendment has been prepared under Mandate M/131 “Pipes, tanks and ancillaries not in contact with water intended for human consumption” given to CEN by the European Commission and the European Free Trade Association in order to meet the requirements of the Mandate given under the EU Construction Products Directive (89/106/EEC). Although the scope of BS EN 10255:2004 has not changed, BS EN 10255:2004 incorporating Amendment 1:2007 -  unusually for an amendment -  will supersede BS EN 10255:2004.Contents Include:Normative references Terms and definitions Classification and designationInformation to be obtained from the purchaserMandatory informationExamples of ordering by outside diameter and thickness Ordering by thread size and seriesManufacturing process Steelmaking processTube manufacturing process Delivery conditionsAlternative finishes and protection of the tube endsSuitability for hot dip galvanizing Hot dip galvanized conditionRequirements Chemical composition and mechanical propertiesAppearance Dimensions, masses and tolerancesLeak tightness Dangerous substances Reaction to fireType of inspection Inspection documentsTensile test Bend testFlattening test Leak tightness testDimensional inspection Visual examination Marking Temporary protective coating Evaluation of conformityInitial type testing (ITT) CharacteristicsProduct familiesUse of historical data Deemed to satisfy’ provisions and use of reference tabulated dataSamplingFactory production control (FPC) EquipmentRaw materials and componentsProduct testing and evaluation Non-conforming products Correlation between specified outside diameter, thread size, and nominaldiameterTypes of tubes with wall thickness different from medium and heavy seriesMarking Clauses of this European Standard addressing the provisions of the ECConstruction Products Directive for applications covered by Mandate M/131Scope and relevant characteristics Procedure for attestation of conformity of pipesDeclaration of conformity CE marking and labellingBS EN 10255:2004 replaces BS 1387:1985, which has been withdrawn.
