17、 Kingdom. BS EN 10314:2016EN 10314:2016 (E) 4 Introduction Minimum values for tensile properties are specified in European Standards for steels and other metals for elevated temperature service. Such values are used to determine design strength values particularly where the materials are used in pre
18、ssure systems. Two International Standards, ISO 2605-1 and ISO 2605-2 (meanwhile withdrawn) were adopted by CEN as European Prestandards, ENV 22605-1 and ENV 22605-2. They set out procedures, based on statistical assessments of bodies of data, for the derivation and verification of minimum values of
19、 0,2 % proof strength at elevated temperatures. These procedures determine the minimum values from lower confidence lines. A third International Standard, ISO 2605-3, adopted by CEN as ENV 22605-3, sets out procedures for determining minimum values from the average trend behaviour of the property of
20、 interest as a function of temperature. One of the purposes of the procedures in ISO 2605-1 and ISO 2605-2 (ENV 22605-1 and ENV 22605-2) is to give an alternative to the requirement for elevated temperature tensile acceptance tests on individual products by organizations and manufacturers contributi
21、ng data for assessment and as a result of this to reduce the test frequency. Experience has shown that the procedures in ISO 2605-1 and ISO 2605-2 (ENV 22605-1 and ENV 22605-2) have limitations affecting the relationship between derived minimum property values and the minima of the test data arising
22、 from the statistical and some subjective decisions at various stages of the procedures. They also require relatively large amounts of data to produce an acceptable level of accuracy. The procedure set out in ISO 2605-3 (ENV 22605-3) requires less data but because it is designed to always give conse
23、rvative values from few data can give non-representative results. However, the principle of this procedure is considered to be more realistic and is adopted as the basis of this European Standard; the objective is to produce an assessment procedure for tensile property data which is simple to operat
24、e, gives representative results and is usable in computerized form. This European Standard, which supersedes EN 10314:2002, which in turn superseded ENV 22605-1, 2 and 3, sets out a method for deriving minimum proof strength values for steels at elevated temperatures with the intention that such val
