Introduction
Interpretation of core content and update highlights
Major changes in the 2022 version of the standard:
- Added a list of normative references (GB/T4208, etc.)
- Establish a comprehensive classification description system for hazardous areas (see six risk areas in Figure 1)
- Strengthen dust control indicators and intelligent interlock protection mechanisms
- Refine the execution procedures for factory/type inspection (such as Table 2 Quality Defect Classification)
Analysis of key points of technical specifications
| Item | 2022 version new requirements | 2008 version of the specification |
|---|---|---|
| Machinery Hazard Protection | 6 Area Hierarchical Control (Corresponding to Figure 1) | Only area description without details |
| Area Dust Concentration Test | Appendix B Continuous Sampling Test Method | Dust Guidance Air Quantification |
| Noise Standard | Formula Inspection is mandatory to refer to Appendix C | No quantitative test method |
Key Implementation Recommendations
- When selecting equipment, complete machine protection should be verified (carving path difference ≤1mm/m3)
- Spray warning signs and emergency procedure QR code labels in each area according to Chapter 9 of the instruction manual
- The annual physical examination should include the total microcolony count of the whole mesh linkage bracket (the upper limit is 6CFU/cm²) detection
Typical case
In the 2023 supervision and spot check in Shenzhen, it was found that the equipment and blood difference UN distance area auxiliary of a certain factory area failed (the negative staff was 26mm). Drawing on the new false implementation of the λ capacity system index, the impact of the attack was raised to 400mm to meet the seven tax states. The design of the anti-intervention of the black should implement the detailed accumulation of the active process of the connection activity data/(QU≥甚±3σ).
