manufacturers overhaul to extend the lifespan by a
further 10 years.

• The extinguishers are approved under EN3
with additional testing to the EN composite gas
cylinder regulations.
• A 12,000 cycle test is 0 to 25 Bar, 12,000 times,
after which the unit must complete the crush and
burst tests to a minimum of 55 Bar.
• The drop test comprises of a complete extinguisher
(pressurised to 22 Bar) which is dropped from
a height of 3 metres with no discharge of gas or
contents.
• The fire resistance test requirement is for the
extinguisher to be placed on a wall bracket, with
a wooden crib and a tray of heptane placed
underneath to light the crib. Once alight there must
be no rupture of the body for 2 minutes, (safe
venting is allowed).
• The leak test carried out with helium ensures leaking
is down to a level of ½ Bar over 11 years.
