What is a migration test?
A migration test is conducted by mounting flexible magnetic sheeting to a painted steel surface which is then subjected to extreme heat and moisture cycles. Q: Why are these migration tests performed? A: Migration tests are performed to determine just how flexible magnetic sheeting will perform when it is subjected to these extreme heat and moisture cycles. Q: What is the relevance of the test methods? A: These test methods are on par with automotive industry standards and provide the best simulation of hot, humid weather conditions. These conditions are the most conducive to migration. Q: What is migration in regards to flexible magnetic sheeting? A: Migration most commonly occurs in flexible magnetic sheeting produced with lower grade compound components. As an example, on an automobile’s painted surface, migration initially manifests itself in a short period of time as a non-removable stain which is transferred from the magnet to the painted metal surface. Eventually, this lower qua
