Introduction
GB/T 3653.1—2024 Standard Interpretation
| Standard Dimensions | Old version (GB/T 3653.1—1988) | New version (GB/T 3653.1—2024) |
|---|---|---|
| Reagent Requirements | The use of anhydrous sodium carbonate and analytical balance is not specified | Anhydrous sodium carbonate (5.1) and analytical balance (6.2) are added to improve the accuracy of the experiment |
| Titration method | Direct titration with sodium hydroxide solution | The use of mannitol is added to optimize the accuracy of endpoint determination |
| Data processing | No clear requirements for repeatability and reproducibility | Introduce repeatability limits and reproducibility limits (see Chapter 10) to improve the reliability of results |
Practical application case analysis
Case background:A steel company needs to regularly test the boron content during the production of ferroboron to ensure product quality.
Implementation steps:
- Sampling and sample preparation in accordance with GB/T4010, ensuring that the sample particle size all passes through the 0.088mm sieve.
- Use analytical balance (sensitivity 0.1mg) to weigh 0.50g of sample.
- Use anhydrous sodium carbonate and sodium peroxide to melt and decompose the sample, and then extract and filter it with water.
- Use an acidometer and sodium hydroxide standard solution (c=0.1mol/L) to titrate and record the consumed volume.
Implementation suggestions
To ensure the effective implementation of GB/T 3653.1-2024 standard:
- Instrument calibration: Calibrate the acidometer and balance regularly to ensure measurement accuracy.
- Staff training: Provide professional training for experimental personnel on titration operations and data analysis.
- Quality control: Set up blank tests and parallel sample determinations to monitor experimental deviations.
