Corrosion tests in artificial atmospheres-Salt spray test chamber
Function
Salt spray test chamber is used for the quality inspection and salt
corrosion resistance test of a variety of materials, including
metal plating, metal, electronic components, chemical coatings,
paint, automobiles, motorcycles, metal ware, screws, springs,
magnetic materials, organic and inorganic coating, anodizing,
anti-rust oil industry etc. after the surface treatment.
It can meet a number of tests such as neutral salt spray (NSS),
acid salt spray (ASS), and copper acceleration (CASS). It is the
most cost-effective product for the salt spray corrosion test.
Testing method
Neutral salt spray test (NSS test), acetic acid salt spray test
(AASS test), salt spray test (SS test), copper accelerated acetic
acid salt spray test method for salt spray test (CASS test) and so
on; (For CASS test, we recommend the PP material or thickening PVC
chamber with high temperature resistance)

According to CSN, JIS, ASTM standards, can be set to constant
temperature control:
- Brine spray test: NSS (neutral); AASS (acid)
- Temp. inside chamber: 35 ℃ ± 1 ℃
- Pressure air bucket: 47 ℃ ± 1 ℃
- Corrosion resistance test: CASS (copper acceleration), (For CASS test, we recommend the PP material or thickening PVC
chamber with high temperature resistance)
- Temp. inside chamber: 50 ° C ± 1 ° C
- Pressure air bucket: 63 ℃ ± 1 ℃
Heating system
The heater is made of advanced titanium protective tube, built-in
nickel-chromium alloy infrared heater core. Heating up fast which
reduce the standby time and make uniform temperature distribution,
with P.I.D + SSR control.
Cover-open method
SNS cylinder lift mode, through the SNS switch solenoid valve
control, the user can press the button switch simply, the cylinder
can open or close the cover automatically.
External material process
Paint production process, plus a layer of PP bag slot, which
effectively avoid rust caused by paint drop, corrosion and other
defects; inside and outside the box adopts PVC board reinforcement,
which is not easy to deformation.
Replenishment function
Automatic water function when the chamber and pressure bucket with
water level is low, don’t need to add water manually.
Executive standard
The chamber conforms to:
GB/T 2423.17 Basic test procedures for electric and electronic
products Ka"- salt spray test methods;
