Submit Salt Spray Spray Test Samples to the Laboratory

Testing of salt spray (salt fog) has become increasingly popular over the years because accelerated corrosion testing of various materials, coatings, etc. Although many samples of standard geometry (panels, etc.) have been made and received and the duration of the test has been established, there are still problems that need to be addressed before the sample must be submitted for exposure to salt spray.

Will the sample sample be tested with a predetermined procedure? In many cases there are existing specifications which describe in great detail the sample geometry and the testing requirements including the criteria for passing / failing at the end of salt spray exposure. Care must be taken regarding sample making and compliance with subject specifications. After the sample is prepared, it must be made very clear to the testing laboratory what are the requirements for the salt spray test and perhaps more importantly, what are the requirements for the post-test evaluation. Often after samples finish their salt spray exposure it needs to be evaluated for blistering, rust, pitting, etc. The laboratory must have knowledge of post-test evaluation procedures and specific pass / fail criteria for each sample.

Is the sample being tested as a research tool? Not infrequently different base materials and / or coatings experience exposure to salt spray to determine the effect of changes in materials / coatings in preventing corrosion. These types of tests are often carried out with routine checks to document the condition of the sample during exposure to salt spray. This examination is usually carried out every day during the normal opening and closing of the salt spray chamber. Excessive interference from salt spray tests can have a negative impact on the validity of the test so that these intermediate inspections must be kept to a minimum.

Are samples being tested for actual parts or assemblies? Like standard test panels, parts and calorimeter indonesia assemblies can be tested with specific test specifications available. Standard test panels usually experience exposure to salt spray while suspended at certain angles to vertical in space. Parts and assemblies will usually have a more irregular geometry and must be considered when placed in the test room so that the "pool" of saline solution does not occur on the surface of the part - proper continuous drainage is very important. The orientation of parts and assemblies in space is usually done in a way that mimics orientation when parts or assemblies are placed in service.

Does the test need to be documented in a special way? It is not uncommon to have an interest in documenting test results outside of the data obtained during standard post-test evaluations. The most common documentation is the use of photos. Photos can be placed in a final test report that can be distributed widely and easily so that the actual test sample does not have to be seen directly. It is important to notify laboratory personnel before the test begins what type of documentation will be needed. Electrical tests can also be carried out on electrical assemblies that have been exposed to salt spray - these types of samples can be pre-wired and samples can be evaluated when the sample is in a room that is exposed to salt spray (with cables run outdoors through a water seal).
