General inspection of import and export of steel Part 4. sample preparation requirements1 ScopeThis section SN/T 2412.4 provides for import and export of steel test sample preparation general requirements, this part applies to the import and export of steel products (including Preparation of the sample plate, rod (wire), shapes, pipes, etc.) required to detect physical and chemical properties.2 Normative referencesThe following documents contain provisions which, through reference in this part of the provisions of this section. For dated references, all subsequent Amendments (not including errata content) or revisions do not apply to this section, however, encourage the parties to reach an agreement is part of the present study Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this section. GB/T 228 metal materials at room temperature tensile test method GB/T 3655 Method (band) magnetic properties with Epstein measuring electrical steel sheet3 Terms and DefinitionsThe following terms and definitions apply to this section. 3.1 Physical and chemical testing process needs to be processed into metallic material standard samples meet the standard requirements in order to ensure that the test procedure and standardized test The results can be compared, thereby effectively evaluate the performance of metal materials. Usually referred to as a sample. Importers need to adopt standard steel test specimens are. tensile, impact and bending. 3.2 Small samples before processing standard sample from a metal material for an examination of the cut out, cut the sample generally use cut and hot cutting, etc. method.4 steel sample preparation4.1 General principles of sample preparation Preparation of the sample in the sample can not be subjected to heat treatment or other processing, sample processing should generally be mechanical cold working, such as Thermal processing, such as EDM must remove the surface layer of the heat-affected. Sample preparation needs to be removed before the heat affected zone of the sample, the general heat-affected zone should be greater than 20mm. The following provisions are general sample preparation, sample preparation specific dimensions and deviations, see the specific provisions of the main criteria. The main testing standards See Appendix A, for future reference. 4.2 tensile specimen shape and size 4.2.1 Overview Tensile test, the shape and size of the sample to a large extent affected the final result, the tensile specimens in each test gauge standard Given very detailed, this standard to shape the material (plates, rods, tubes, etc.) Classification given shape and size of conventional tensile specimen. Full-sectional sample is divided into tensile specimens and the scaling ratio from the two types, usually machined test and peaceful without being machined, the cross-section through Usually circular, rectangular, shaped and full cross-sectional shape is not processed. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 2412.4-2010_English be delivered?Answer: Upon your order, we will start to translate SN/T 2412.4-2010_English as soon as possible, and keep you informed of the progress.
