Introduction
In-depth interpretation of the National Standard of the People's Republic of China GB/T 34487—2017
| Standard dimensions | GB/T 34487—2017 | Comparison standards (such as ISO/ASTM) |
|---|---|---|
| Scope of application | Determination of shear properties of aluminum alloy products for structural parts | International standards focus more on general metal material testing |
| Test method | Shear load is applied until fracture, and the shear strength is calculated | Other methods include tension and bending tests |
| Specimen preparation | Double shear and single shear, with specific dimensions and deviations clearly specified | There are fewer specimen types in general standards |
Overview of aluminum alloy shear test methods
GB/T 34487-2017 specifies the shear test methods for aluminum alloy products used for structural parts, which mainly evaluates the shear performance by applying shear load to the specimen until the maximum load occurs or the specimen breaks.
Explanation of key terms
Comparative analysis of standard frameworks
GB/T 34487—2017 is unique in shear test methods. The following is a comparison with other international standards:
- Scope of application: Focuses on aluminum alloys for structural parts, covering two types of double shear and single shear.
- Specimen preparation: Detailed provisions are made for specimen size, deviation and surface roughness to ensure the accuracy of test results.
- Test equipment: It is clearly required to use a level 1 or higher testing machine specified in GB/T16491 or GB/T16825.1.
Implementation recommendations
To ensure the effective implementation of the standard, it is recommended that:
- Equipment calibration: Regularly calibrate the testing machine and fixture to ensure that the measurement accuracy meets the requirements.
- Personnel training: Provide professional training to operators to master the specific requirements and test steps of the standard.
- Quality control: Establish a quality control system to ensure the standardization of the sample preparation and testing process.
Appendix interpretation
The appendix in the standard specifies the specific requirements of the double shear fixture, single shear fixture and specimens in detail. For example, the double shear fixture consists of a pressure head, a shear ring, a support ring and a base, and the material, hardness and surface roughness of each component are clearly specified.
