updated BS 5306

[Guest steve]

can anyone confirm if the new hydrotest from after the first hydrotest for CO2 extingusihers has changed from 5 years to 10 years?

It's been every 10 years since BS5306-3:2000 and the brief requirement for 5 year extended service on CO2 brought in the 2000 edition was repealed in the 2003 edition. Since then we've had 2009 & 2017 editions, the latter being current.

The traditional regime in the 20th Century was 10 years from new unless there was a full service history in which case the test could be delayed until 20 years from new, unless the extinguisher was discharged between 10 & 20 years in which case it had to be tested before recharge. After the first retest the second was a fixed 10 years then the third and any subsequent tests were at a fixed 5 year interval.
