ASTM B117 Salt Fog Test Corrosion Chamber
ASTM B117 Salt Fog Test Corrosion Chamber is mainly used for
surface treatment of various materials, including coatings,
electroplating, inorganic and surface films, and anodizing. After
anti-corrosion treatment such as anti-rust oil, test the corrosion
resistance of its products.

Features
1. corrosion test chamber has an automatic/manual water adding
system, which can automatically replenish the water level when the
water level is insufficient, and the test is not interrupted.
2. The temperature controller uses digital display, and the PID
control error is ±01.℃;
3. salt corrosion chamber,Double over-temperature protection,
warning of insufficient water level to ensure safe use.
4. The laboratory adopts the direct heating method of steam, the
heating speed is fast and uniform, and the standby time is reduced.
5. Salt Fog chamber,The precision glass nozzle is sprayed with
adjustable mist, and the conical disperser of the spray tower of
the mist volume is evenly scattered and diffused, and naturally
falls on the test card, and ensures that no crystalline salt is
blocked.
The ASTM B117 cycles include
Step 1: 35°C salt spray
Step 2: Go back to Step 1
Conditions for the salt spray test chamber to be used for ASTM B117
testing:
Salt spray deposition rate measured with a 100mm diameter funnel:
1–2 ml/hour;
Recommended spray pressure: 8psi;
Recommended solution flow: 1100 liters, 0.6 liters/hour; 600
liters, 0.5 liters/hour
