Standard Evolution and Core Changes
Technical Dimensions GJB 483-1988 GJB 483A-2021 Upgrade Points Water-based Foam Decontamination No clear requirements Add a special chapter Specify 100L:(8~10)kg:3kg modulation ratio Reliability Indicators Not systematized MTBF≥100h Increase operational reliability verification Electromagnetic compatibility No requirements Dual requirements for vehicle + subsystem Comply with GJB 1389A/GJB 151B
Detailed explanation of key technical indicators
1. Decontamination system performance
The standard stipulates that spray gun disinfection must meet the requirements of single nozzle flow ≥18L/min and working pressure ≥0.3MPa. Door-type disinfection requires the configuration of no less than 10 nozzles and 2 supplementary disinfection spray guns. The volumetric efficiency of the high-pressure elimination system must be ≥90%, and the total efficiency must be ≥70%.
2. Environmental adaptability verification
- High temperature operation: 40℃ continuous operation verification
- Low temperature storage: Functional check after storage at -40℃ for 24 hours
- Altitude adaptation: Maintain core functions at 4500 meters
Implementation suggestions
Key points of quality inspection
Special attention should be paid to the identification inspection:
- Heat dissipation verification of hydraulic system oil temperature ≤87℃
- Safety valve opening pressure deviation ≤±10%
- Electromagnetic compatibility test must include CE102/RE102 items
Application value of standard
The new version of the specification introduces reliability quantitative indicators (MTBF≥100h) and maintainability requirements (MTTR≤2h) for the first time, providing a technical basis for the full life cycle management of equipment. The newly added GJB 150.18A impact test requirements (20g acceleration) significantly improve the battlefield adaptability of equipment.
