Introduction

Interpretation of the core content of the standard

This standard specifies the technical requirements for the entire life cycle of the aviation fuel supply system cleaning operation vehicle, including:

Vehicle structure design (tank volume, pipeline layout, etc.)
Safety protection system (static elimination, interlocking device, etc.)
Environmental performance indicators (noise control, emission standards)
Adaptability to special working conditions (-40℃~60℃ environmental operation)

Comparison of key technical indicators

Project	Atmospheric pressure recovery tank	Vacuum recovery tank
Pressure resistance requirements	36kPa static pressure for 30min	1.25 times rated pressure
Weld inspection	10% flaw detection of circumferential welds	100% inspection of all welds
Capacity design	Including expansion capacity	Calculated according to vacuum degree

Analysis of implementation points

Typical application scenarios

After Shanghai Pudong Airport adopted the cleaning vehicle that meets this standard:

Valve well cleaning efficiency increased by 40%
Operation safety accidents reduced to zero
Wastewater recovery rate reaches 100%

Background of standard evolution

Main upgrades of the 2020 version of the standard:

Added requirements for underground emergency lifting devices (refer to GA 494)
Strengthen the reliability of electronic control systems (inherent effectiveness ≥0.8)
Refine the selection specifications for explosion-proof fans (GB 26410)
