Closed chamber evaporative emission SHED test chamber
Closed chamber evaporative emission SHED test chamber
1. Product introduction:
SHED closed evaporation test chamber is mainly used to measure the emission of fuel evaporation pollutants under the conditions specified by national/European/American standards and other regulations. The tests include: heat soak loss, refueling emission loss, and 24h/48h/72h daytime loss. . The temperature control range is +15~+60℃, which can simulate two modes of constant temperature and day and night temperature changes.
2. Meet test standards:
GB18352.3-2005 Light-duty vehicle pollutant emission limits and measurement methods (China III and TIV stages)
GB18352.5-2013 Light vehicle pollutant emission limits and measurement methods (China Phase 5)
GB18352.6-2016 Light-duty vehicle pollutant emission limits and measurement methods (China Phase Six)
T/CSAE 121-2019 "Test Method for Evaporative Pollutant Emissions from Non-Fuel Related Vehicle Parts and Materials"
European standard (Euro 6), American standard EPA (Code of Federal Regulations40O Part 86 (EPA Tier-I)) and American standard CARB (CCR Title13 (CARB LEV I-II)) related technical requirements.

|
Sealing |
When there is an overpressure of 1000P8, the gas leakage is less than 10-3x1m³/min, and the gas flow difference between the inlet and outlet is less than 1% |
|
Background concentration in the test chamber |
Toxic acid ≤0.006mg/m³ |
|
Adiabatic |
Climate chamber walls and doors should have effective thermal insulation |
|
Noise |
The noise when the climate box is working ≦60dB |
|
Continuous working time |
The climate chamber has a continuous working time of 28 days |
|
Monitoring parameters |
Monitor and display the temperature and humidity in the cabin, air supply and exhaust volume, power on and off time, working time, data can be transferred and stored |
|
Humidity control method |
The dew point control method is used to control the relative humidity of the working cabin. The humidity is stable, the fluctuation amplitude is <3%.rh, and no water droplets will be produced on the bulkhead. |
4. The following factors ensure the reliability of the test:
Low background emissions significantly below legal specifications
Delivery of fully assembled systems
Short on-site installation and commissioning times
Determine the size of the test chamber according to the size of the sample (drive-in, walk-in, mini SHED, micro SHED, running loss SHED, drive-in (driving on a dynamometer)
If you have any questions about the selection of SHED closed evaporation test chamber, you can consult the relevant technical personnel of "Environmental Instrument".
