Standard Overview
BS EN 4840-002:2023 is a British national standard that fully adopts the European standard EN 4840-002:2023. The standard was developed by ASD-STAN (European Aerospace and Defense Industry Standardization Association), and technical committee ACE/6 is responsible for the preparation of avionics, electrical and fiber optic technology.
Core content analysis
Product type Typical style Temperature range Material properties EN 4840-101 Type AA-W -30°C to 105°C Semi-rigid polyolefin, limited fire hazard EN 4840-102 Type D/G/K -75°C to 150°C Semi-rigid elastomer EN 4840-103 T/U/V Type -55°C to 200°C Fluororubber Material
Key Dimensional Parameters
The standard contains detailed dimensional specifications for 23 styles (AA-W), including:
- Style AA: Small lip bottle, maximum diameter 5.2-8mm
- Style D: Lipless straight bottle, length range 25.4-210mm
- Style T: D-sub micro straight plug-in protective cover, tolerance ±5%
All dimensions are marked as recovered (Recovered) and as supplied (As The two parameters are available in two versions and include a tolerance range of ±10%-±30%.
Technology Evolution Analysis
Compared with the previous version of the standard, the 2023 version has the following major updates:
- Added 45°/60° multi-angle specifications for the Style W long-neck angled protective cover
- Optimized the dimensional chain tolerance system of the D-sub series (T/U/V type)
- Clarified the optional configuration requirements for drainage holes and connector cover lifting eyes
Implementation recommendations
Note when applying this standard:
- Different materials (such as EN 4840-103 fluororubber) may cause the actual mass to exceed the maximum value marked
- The d3 diameter of some styles may be reduced due to the material type, which needs to be confirmed with the manufacturer
- The standard does not provide legal exemptions, and users need to ensure compliance with local regulations
