EN 10314:2002 (E)4IntroductionMinimum values for tensile properties are specified in European Standards for steels andother metals for elevated temperature service. Such values are used to determine designstrength values particularly where the materials are used in pressure systems.Two International Standards, ISO 2605-1 and ISO 2605-2 are available and have beenadopted by CEN as European Prestandards, ENV 22605-1 and ENV 22605-2. They set outprocedures, based on statistical assessments of bodies of data, for the derivation andverification of minimum values of 0,2% proof strength at elevated temperatures. Theseprocedures determine the minimum values from lower confidence lines. A third InternationalStandard, ISO 2605-3, adopted by CEN as ENV 22605-3, sets out procedures for determiningminimum values from the average trend behaviour of the property of interest as a function oftemperature.One of the purposes of the procedures in ISO 2605-1 and ISO 2605-2 (ENV 22605-1 andENV 22605-2) is to reduce the requirement for elevated temperature tensile acceptance testson individual products by organizations and manufacturers contributing data for assessment.Experience has shown that the procedures in ISO 2605-1 and ISO 2605-2 (ENV 22605-1 andENV 22605-2) have limitations affecting the relationship between derived minimum propertyvalues and the minima of the test data arising from the statistical and some subjectivedecisions at various stages of the procedures. They also require relatively large amounts ofdata to produce an acceptable level of accuracy.The procedure set out in ISO 2605-3 (ENV 22605-3) requires less data but because it isdesigned to always give conservative values from few data, it like the other procedures, cangive non-representative results. However, the principle of this procedure is considered to bemore realistic and is adopted as the basis of this European Standard; the objective being toproduce an assessment procedure for tensile property data which is simple to operate, givesrepresentative results and is usable in computerised form.This European Standard, replacing ENV 22605-1, -2 and -3, sets out a method for derivingminimum proof strength values for steels at elevated temperatures with the intention that suchvalues are specified in relevant product standards.This European Standard does not specify a verification procedure. Verification of tensileproperties at elevated temperatures is normally specified in the relevant product standardusing the minimum property values derived by the procedure established in this EuropeanStandard.The method proposed has been tested for proof strength values of steel. However, it isconsidered that the method can also be applied for other metals and for the derivation ofminimum values of tensile strength at elevated temperatures.SIST EN 10314:2003
