Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 5452—2017
1. Analysis of the background of standard formulation and technological evolution
GB/T 5452—2017 "56% Aluminum Phosphide Tablets" was drafted according to the rules given in GB/T1.1—2009, replacing the previous GB/T5452—2001 standard. This revision mainly optimizes the following aspects:
- The mass fraction of aluminum phosphide is relaxed from ≥56.0% to (56.0±2.5)%
- The sample weighing range is adjusted from 0.14g~0.16g to 0.18g~0.20g
2. Comparative analysis of standard frameworks
| Standard version | Mass fraction of aluminum phosphide/% | Average mass per piece/g | Vertical strength/N | Powder and fragments/% | |
|---|---|---|---|---|---|
| GB/T 5452—1985 | Specific indicators not specified | ||||
| GB/T 5452—2001 | ≥56.0 | - | - | ||
| GB/T 5452—2017 | 56.0±2.5 | 3.2±0.1 | 70 | 1.5 | |
3. Suggestions and precautions for the implementation of the standard
Case analysis: In actual application, quality control must be carried out strictly in accordance with the test methods in the standard. For example, in the determination of the mass fraction of aluminum phosphide, the sample weight should be accurate to 0.0001g, and potassium permanganate standard titration solution and oxalic acid standard solution should be used for titration.
Implementation suggestions: 1. Strengthen personnel training to ensure that operations comply with safety regulations; 2. Regularly calibrate instruments and equipment to ensure measurement accuracy; 3. Establish a complete quality traceability system to facilitate problem troubleshooting.
