《GB/T 33329-2016颜料和体质颜料 灼烧损失和灼烧残余物的测定》由TC5（全国涂料和颜料标准化技术委员会）归口，主管部门为中国石油和化学工业联合会。
Introduction
1. Background of Standard Formulation
The formulation of GB/T33329-2016 is based on the pigment industry's demand for product quality control, especially performance testing under high temperature conditions. This standard fills the gap in the determination of pigment ignition loss and residue in China, and provides a reliable testing basis for downstream industries such as coatings and inks.
2. Comparison of standard frameworks
| Standard dimensions | GB/T33329-2016 | International standard correspondence | Main differences |
|---|---|---|---|
| Scope of application | Determination of ignition loss and residue of pigments and extenders | Similar to ISO international standards | Optimization of test condition details |
| Instrument requirements | High temperature furnace, balance, etc. | General laboratory equipment | Increased equipment accuracy requirements |
3. Analysis of standard technology
High temperature furnace is the core equipment in the standard, which is used to simulate the performance changes of pigments in high temperature environment. Its temperature control accuracy directly affects the accuracy of the test results.
Actual application case: aluminum silver powder detection
Through the GB/T33329-2016 method, a company found that the loss rate of its aluminum silver powder was high at high temperature. After optimizing the production process, the ignition loss was reduced from 5.8% to 3.2%, significantly improving product quality.
