《GB/T 13705-2019船用无线电通信设备一般要求》由TC531（全国船舶电气及电子设备标准化技术委员会）归口，TC531SC2（全国船舶电气及电子设备标准化技术委员会航海仪器分会）执行，主管部门为国家标准化管理委员会。
Introduction
Standard Evolution and Technology Upgrade
GB/T 13705-2019, as the basic national standard for marine radio communication equipment, has achieved three major breakthroughs compared with the 1992 version:
| Technical Dimensions | 1992 Version | 2019 Version | Upgrade Points |
|---|---|---|---|
| Environmental Adaptability | 8 Items | 19 Items | 11 New Harsh Environment Requirements Such as Thermal Shock and Dust |
| Electromagnetic compatibility | 3 outlines | 7 subdivisions | Detailed tests such as conducted emission and surge immunity |
| Safety protection | Not an independent chapter | 6.10 special chapter | Specify indicators such as insulation resistance and sound pressure limit |
Core equipment performance specifications
Taking VHF radio equipment as an example, the standard requires:
- Frequency accuracy: 156.025-162.025MHz range error ≤±10ppm
- Polarization mode: Vertically polarized antenna configuration
- Interface requirements: Mandatory voice signal intercommunication with VDR equipment
Typical application scenario: The JRC JHS-800 equipment installed on a bulk carrier needs to pass 6.8.12 rain test (IPX6) and 6.9.3 RF conducted disturbance test (10Vr.ms)
Analysis of key test methods
1. Electromagnetic compatibility test
| Test items | Standard clauses | Severity level | Judgment criteria |
|---|---|---|---|
| Electrostatic discharge | 7.8.7 | ±8kV contact discharge | Function self-recovery after test |
| Surge immunity | 7.8.6 | 2kV (power line) | No data loss |
2. Environmental adaptability test
Portable devices must pass the following:
- Thermal shock test: 70℃→25℃ water temperature sudden change (7.7.5)
- 20m drop test: Maintain waterproof performance after water surface impact (6.8.19b)
Implementation suggestions
- Equipment selection: Prioritize products that have passed 8.4 type inspection (including 28 items such as salt spray/mildew growth)
- Installation specifications: Mark the safe distance from the magnetic compass as required by 6.9.8 (usually ≥1m)
- Maintenance points: Power on the inventory equipment for 2 hours every 6 months (10.3.2)
