This document replaces GB/T 5482-2007 "Dynamic Tear Test Method for Metallic Materials". Compared with GB/T 5482-2007, except for the structure In addition to adjustments and editorial changes, the main technical changes are as follows. a) Change the term "fiber section ratio" to "shear section ratio" (see 3.4,.2007 version of 3.4); b) Added processing accuracy requirements for specimens using end positioning tests (see 4.2.1); c) The regulations on the reading resolution of testing machines have been changed, and the reading resolution of testing machines with a maximum impact energy value of 3000J and above has been added. Regulations (see Table 3, Table 2 of the.2007 edition); d) The test process has been changed and improved (see 6.1, 6.2, 6.1, 6.3 of the.2007 edition); e) Delete the requirements for temperature measurement instruments (see 6.2 of the.2007 edition); f) The requirement for the number of specimens is deleted (see 6.6 of the.2007 edition); g) Added a computer-aided method for measuring shear section ratio (see 7.1.2).

Dynamic tear test method for metallic materials1 ScopeThis document specifies the specimens for dynamic tear testing of metallic materials and their preparation, testing machines, testing procedures, calculation of shear section ratio, and testing Results processing and test reporting. This document is suitable for measuring the dynamic tearing energy and shear fracture of metallic materials or welded joint samples with a Rockwell hardness value less than 36HRC. face rate.2 Normative reference documentsThe contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to this document. GB/T 2975 Sampling location and sample preparation for mechanical property testing of steel and steel products GB/T 3808 Inspection of Pendulum Impact Testing Machine JJG145 Pendulum Impact Testing Machine Calibration Regulations3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 dynamicteartest dynamicteartest On the impact testing machine, the dynamic tearing specimen in the state of a simply supported beam is punched once, and its energy absorption and shear section ratio are measured. test. 3.2 dynamictearenergy dynamictearenergy The energy absorbed by the sample during the dynamic tear test is used to characterize the ability of a metal material of a specific thickness to resist dynamic tearing. 3.3 The fracture surface of the dynamic tear specimen after punching. Note. Macroscopically, the fracture surface of the sample generally has a crystalline, fibrous (including shear lip) or mixed morphology. 3.4 The percentage of the ratio of the fibrous fracture area to the original cross-sectional area at the notch of the specimen.4 Samples and their preparation4.1 Sampling 4.1.1 The cutting position and direction of the sample blank should comply with the requirements for impact specimens in GB/T 2975 or relevant product technical requirements and specifications. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 5482-2023_English be delivered?Answer: Upon your order, we will start to translate GB/T 5482-2023_English as soon as possible, and keep you informed of the progress.
