methods are known to have corrosion related failures in use. In addition, these methods may be useful for special applications such as on moving vehicles or seafaring vessels. Test method 7 uses the same neutral pH solution as methods 1 to 6, while test method 8 uses an acidic solution, which may be useful for applications with significant industrial pollution.NOTE Another complication with the use of test methods 7 and 8 is that the rapid drying rate may be very difficult to achieve in chambers large enough for commercial modules.
