Luxfer Gas Cylinders, a unit of Luxfer Holdings PLC, has successfully completed the first testing milestone for LCX-EL® SCBA cylinders with 30-year life under DOT Special Permit 14232.

In 2008 Luxfer Gas Cylinders designed and manufactured the first cylinders under the brand LCX-EL® with an increased service life from 15 to 30 years.

The qualification programme mandated by the US DOT under Special Permit 14232 requires a sample of 30 cylinders of each size from the first year of manufacturing to be collected and tested at ten years of service.

Then a second sample of 30 cylinders from the first year of manufacture is also collected and tested at 15 years of service. Upon successful completed of the test at both services, all cylinders of that design continue as normal beyond the standard life of 15 to 30 years.

Luxfer has completed the first milestone in the process and passed all inspections and tests required by the US DOT under Special Permit 14232 at ten years of service life for the first batch of nine litre LXC-EL® SCBA cylinders sold in 2008.

In a further five years, another group of nine litre LCX-EL® cylinders from the first year of manufacture will be tested.
