EMEMBER!!!!
FIVE YEARS FOR FULL-FIBRE WRAPPED BOTTLES - EN12245 and Pi certified.
THREE YEARS FOR FULL WRAPPED BOTTLES - HSE-AL-FW2 manufactured before July 2003 then five years after retesting for SCI and Luxfer cylinders
THREE YEARS FOR FULL WRAPPED BOTTLES - HSE-AL-FW1
FIVE YEARS FOR HALF WARP BOTTLES
FIVE YEARS FOR ALUMINUM OR STEEL BOTTLES
NOTES and amendments
The new European regulations (TPED) came onto the statute book in July 2003 and at that point the UK specification HSE-AL-FW2 became obsolete ie. no new cylinders could be produced to this specification for the UK market.
From July 2003, the European standard EN 12245 became the only acceptable specification for new cylinders.
All cylinders manufactured and certified to the HSE-AL-FW2 specification prior to July 2003 and retested after July 2003 have their retest period extended from 3 to 5 years at their next retest.
If you have a cylinder manufactured before July 2003 then you need to have it tested 3 years from the original manufactured date. The recertified cylinder will then need retesting after a further five year period.
All cylinders manufactured to EN 12245 and Pi certified to comply with the TPED start with a retest period of 5 years from date of manufacture.
Steel and Aluminium cylinders
In March 2002, European standards for cylinder testing were changed. The familiar old BS 5430 part 1 (steel cylinders) & part 3 (aluminium) were withdrawn and replaced by new standards - BS EN 1968:2002 for Steel Gas Containers, and BS EN 1802:2002 for Aluminium Gas Containers.
I should add that any other cylinders manufactured and certified to other specifications e.g. DOT are not legal in the UK
