CSC welcomes DNV GL adding acoustic emissions testing to its rule set

The global gas cylinder specialist Chesterfield Special Cylinders’ Integrity Management team has welcomed DNV GL’s move to make acoustic emissions (AE) testing the preferred method for carrying out periodical inspections of seamless gas cylinders. The classification society is the first to include AE testing in its rule set, aligning it with a new European Standard for gas cylinders and their periodic inspection and testing (EN 16753), which was introduced in 2016 and favours the AE method.

World-leading experts on AE testing at CSC IM have long argued that hydrotesting, a method where the integrity of seamless gas cylinders is checked by filling them with water, is slower, less safe and more expensive.  

AE testing is also conducted without removing the cylinders from where they are installed.
