1 Scope This part specifies a method of tensile testing of metallic materials at temperatures higher than room temperature in terms of definition, symbols and designations, test piece and dimension measurement, apparatus, test conditions, performance determination, determination result rounding off and test report. This part is applicable to determination of tensile properties of metallic materials at a temperature higher than room temperature. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

In general, all test piece geometries/dimensions are based on measurements taken at room temperature. The exception may be the extensometer gauge length (see 3.3 and 10.2.2). Note: The following properties are generally not determined at elevated temperature unless required by relevant specifications or agreement: ——Permanent set strength (Rr); ——percentage permanent elongation; ——percentage permanent extension; ——percentage yield point extension (Ae); ——percentage total extension at maximum force (Agt); ——percentage plastic extension at maximum force (Ag); ——percentage total extension at fracture (At). 3.1 Original gauge length Lo Gauge length measured at room temperature before heating of the test piece and before application of force. 3.2 Percentage elongation after fracture A Permanent elongation at room temperature of the gauge length after fracture (Lu - Lo), expressed as a percentage of the original gauge length (Lo). Note: For further details, see GB/T 228.1-2010, 3.4.2. 3.3 Extensometer gauge length Le Length within the parallel portion of the test piece used for the measurement of extension by means of an extensometer. 3.4 Extension Increase in the extensometer gauge length (Le) at a given moment during the test. 3.5 Percentage extension Extension expressed as a percentage of the extensometer gauge length (Le). 3.6 Percentage reduction of area
