Applications
The Photovoltaic Ammonia Test Chamber is a testing device designed to evaluate the corrosion resistance of photovoltaic modules in ammonia environments, ensuring their long-term stable operation in harsh conditions such as industrial or agricultural settings.
Standards
IEC 62716: Photovoltaic (PV) modules—Ammonia corrosion testing (The core standard for this equipment).
IEC 61701: Salt mist corrosion testing of photovoltaic (PV) modules.
IEC 60068-2-52: Environmental testing—Part 2-52: Tests—Test Kb: Salt mist, cyclic (sodium chloride solution).
GB/T 2423.17 / GB/T 2423.18: Environmental testing for electric and electronic products—Salt mist testing methods.
IEC Draft 82/722/CDV: Specific requirements for integrated salt mist and ammonia gas exposure sequences.
Features
This equipment can independently perform all test procedures required by IEC 61701 and IEC Draft Standard 82/722/CDV. Specifically, spray testing at severity levels 1-6. damp heat storage, standard atmospheric environment testing, and sample cleaning phases are all completed within the NaCl corrosion chamber. Ammonia spray testing, damp heat storage, spray washing, and drying can all be performed within the NH3 corrosion chamber.

5.NaCl Spray Module: Integrated nozzles and reservoir for salt mist phases (Standard Severity 1-6).
6.Deionized Water Rinse: Internal spray bars for automated sample cleaning between test stages.
Test Procedures
1.Preparation
Sample Preparation: Clean samples and secure them on the sample rack, ensuring they do not touch each other.
Solution Preparation: Prepare a 5% NaCl solution (pH 6.5-7.2) according to the standard.
2.Power-On Test
Power Connection: Connect the power supply and turn on the main switch.
3. Test Operation
Start Test: After confirming parameters are correct, press the “Start” button.
Spray Inspection: Once temperature is reached, the spray system will automatically activate. Observe spray uniformity.
4. Test Completion
Shutdown Procedure: Turn off the spray switch. Allow cooling to below 40°C before disconnecting power.
Sample Removal: Remove specimens for corrosion assessment.
