When properly used, eddy-current devices contribute significantly to early detection of hard-to-see sustained-load cracks.

A great deal of misinformation and exaggeration about SLC is attributable to rumors and inaccurate reports spread by word-of-mouth and the trade press, but especially by the Internet, where the proliferation of inaccuracies is widespread and essentially unregulated.
Any type of cylinder manufactured from 6351 alloy could conceivably develop a sustained-load crack over time if subjected to certain conditions.
Out of a total population of approximately 1,073,000 Luxfer scuba cylinders made of 6351 alloy, only 1.25% have exhibited SLC.
Very slowly, as extensive research by Luxfer and outside laboratories has shown.
SLC is a metallurgical phenomenon that occasionally develops in cylinders made of 6351 aluminum alloy, as well as in other types of pressure vessels and structural components under stress for sustained periods of time.
All composite cylinders have a 15-year service life in accordance with regulations around the world. In the United States, the service life is set by the U.S. Department of Transportation.
Luxfer's carbon composite cylinders must be retested (i.e., requalified for continued service) every five years, the same as aluminum oxygen cylinders.
Luxfer's carbon composite cylinders do not need any special handling equipment-in fact, they are the strongest, most durable cylinders ever made.
Luxfer's medical composite cylinders take standard valves and regulators.
