Introduction
In-depth interpretation of GB/T13522-2024 national standard for bone china
GB/T13522-2024 national standard for bone china is a major revision of the 2008 version of the standard. The main updates include requirements for thermal shock resistance and microwave oven adaptability tests. This article will provide an in-depth interpretation of the technical requirements, test methods and implementation recommendations.
1. Comparison of standard frameworks
| Standard dimensions | Requirements of the 2008 edition | Updated for the 2024 edition |
|---|---|---|
| Water absorption | ≤1.0% | Still ≤0.5% |
| Thermal shock resistance | Small and medium size: heat exchange from 160°C to 20°C without cracking once; large and special size: heat exchange from 140°C to 20°C without cracking once. | Small and medium: 160°C to 20°C heat exchange once without cracking; large and special: 140°C to 20°C heat exchange once without cracking. |
| Microwave adaptability | No relevant requirements | Added 72000J energy heating test, no arcing and no cracking. |
2. Detailed explanation of technical requirements
The technical requirements of bone china mainly cover multiple dimensions such as water absorption, thermal shock resistance, whiteness, and microwave adaptability. Among them, the content of tricalcium phosphate is an important indicator for measuring bone china, and the content in the plain body should not be less than 36%.
Case Analysis: Microwave Oven Adaptability Test
A certain brand of bone china had arcing during the microwave oven adaptability test, and the production process needed to be optimized. It is recommended that the manufacturer improve the raw material ratio and firing process.
3. Implementation Suggestions
- The company should establish a complete quality control system to ensure that all indicators meet national standards.
- It is recommended to calibrate production equipment and testing instruments regularly to ensure the accuracy of test results.
- For new requirements (such as microwave oven adaptability), special test plans need to be formulated and included in the daily testing process.
