Introduction
1. Standard background and technological evolution
This standard GB/T 1964-2023 "Test method for compressive strength of porous ceramics at room temperature" is the second revision of the original standard GB/T 1964-1996. The main modifications include:
- Changed the instrument requirements
- Optimized the sample preparation and test conditions
- Added the provisions for the test environment conditions
- Improved the data processing method
- Added the discrete coefficient requirement
2. Comparative analysis of standard frameworks
| Standard version | Scope of application | Instrument requirements | Test method | Result calculation |
|---|---|---|---|---|
| GB/T 1964-2023 | Applicable to the determination of room temperature compressive strength of porous ceramics | Compliant with GB/T 16491Requirements, automatically record the load and displacement curve | Loading speed is 0.5 mm/min, until failure or deformation 10% | Calculate the compressive strength, mean value, standard deviation and coefficient of dispersion |
| GB/T 1964-1996 | Applicable to compressive strength test of porous ceramics | Manually record load and displacement data | Loading speed is not clear, mainly based on the judgment of the failure phenomenon | Only calculate the compressive strength |
3. Implementation Suggestions and Precautions
Case Analysis: An enterprise adopts GB/T When testing the compressive strength of porous ceramics according to the 1964-2023 standard, it was found that the average compressive strength of the sample was 5.8 MPa and the coefficient of dispersion was 0.12. By optimizing sample preparation and controlling test conditions, the coefficient of dispersion was reduced to 0.08.
- It is recommended to use automatic recording equipment to ensure data accuracy
- Strictly control the temperature and humidity of the test environment
- Pay attention to avoid defects and contamination when preparing samples
- Focus on the coefficient of dispersion index when processing data
