Salt Fog Chamber For LED Lighting Test (ASTM B117 ISO 9227 IEC60068)

Application
 
LED products or components need to do salt spray test?
[Usually only for products or components with salt spray or risk of corrosion in the working environment]
A Metal and its alloy
B Metal coating, such as tinned nickel plating
C Organic coating, such as spray
D: Anodic oxidation film.If you need more models about our test equipment, please reference our chamber-testing（.）com

Under salt fog chamber  that we usually refer to relevant national and industry standards to ensure the accuracy and comparability of test results. for example: 

GB/T 10125, ISO 9227 Artificial atmosphere corrosion test salt spray corrosion

ASTM B117 US standard salt spray test

GB/T 2423.17, IEC 60068-2-11 Salt spray test for electronic products

GB/T 2423.18, IEC 60068-2-52 electronics alternating salt spray test  

Salt spray test: the LED sample is exposed to salt spray environment, simulate the use scenario in the Marine environment, by observing the change of its surface corrosion, electrical performance changes and other indicators, to evaluate its reliability in a strong corrosion environment.

Artificial simulated salt spray test classification:
(1) Neutral salt spray test (NSS test)
It is the earliest and most widely used accelerated corrosion test method. It uses 5% sodium chloride brine solution, the PH value of the solution is adjusted in the neutral range (6.5~7.2) as a spray solution. The test temperature is set at 35℃, and the settlement rate of salt spray is required to be between 1-2ml/80cm2(h).

【 Neutral salt spray test is the most commonly used test method. If no special instructions are made, the salt spray test we talk about usually refers to the neutral salt spray test 】
