Four Reasons for Incorrect Salt Spray Chamber Test Results
The salt spray Test Chamber is mainly used to test the anti-corrosion performance of the product surface, including electroplating, inorganic film, anti-rust oil and paint and other products. However, the device had a testing bug. Therefore, many users also expressed doubts about the need for more accurate test data. Devices cannot be guaranteed 100% correct during trial, a little bit of data error will occur anyway. What is the reason? According to user feedback, there are the following reasons:
First, the salt spray Test Chamber has its own errors
Taking into account the imperfection of design, manufacture and verification, as well as the aging of its components during the use of the Test Chamber, the wear of mechanical parts, fatigue and other phenomena formed by errors. Not only can these parts cause errors, but various auxiliary equipment or accessories can also cause errors.
Second, the error caused by the test method
The operation method should be carried out according to the correct and standardized steps, and the test method should be improved reasonably. When the theory based on the equipment test is not accurate enough, factors such as unreasonable operation and approximate formulas or approximate calculation results will lead to test errors.
Three, the environment and operators make mistakes
The error caused by the fact that the actual environmental conditions are different from the rated conditions, the main factors are temperature, power supply voltage and electromagnetic interference. In addition, the incorrect operation of the operator is also one of the factors, mainly due to the poor recognition ability of the personnel, visual fatigue, slow Detector speed, bad habits and lack of responsibility, etc.
Fourth, the error caused by the instability of the test sample
The salt spray test takes a long time, if the instability of the test sample changes from the test time, even the performance of the salt spray Test Chamber cannot obtain correct test data.
