One of the more recent controversies in the compressed gas market is the use of MAE testing to extend the service life of Carbon Fiber SCBA Cylinders. You can refer to previous blog articles to understand what all of the hoopla is about. In the meantime, it has come to our attention that SP 16320 which allows the procedure is expired. USDOT Permits office published a notification on their website confirming the permit holder Digital Wave applied for renewal but at this time their application has been denied. USDOT indicated they expect ongoing discussion regarding the permit and at some point it may be renewed.
In the meantime, since this is a testing SP and not a manufacturing SP, it is not clear the ramifications to cylinders tested with this method but USDOT will follow up with information on what this means for previously tested cylinders (if anything). However until the permit is renewed, testing by this method is not allowed.
