LPG Hose date ?

[Quantric]

HI Folks I am trying to buy a replacement hose for a Cadac BBQ I bought S/H recently. I noticed a date on the hoses. Is this the manufacturing date or ? I believe the working life is 5 years.



I did try and search for a thread but failed to find any previous.

15 mm o.d. orange high pressure hose to EN16436-1 Class 2 and BS 3212 Type 2.

Thanks Chris

Date of manufacture on hose .
No specific service life but good practice is to replace at a maximum of 10 years .

Yup, it is the production date and the (strong) recommendation is to replace the hose every five years.

Actually 10 years , the NCC actually gave out incorrect information for years , they have now revised it.

Interesting - could you point me in the direction of the NCC statement/guidance to this effect?

Thanks for that - couldn't access a copy anywhere but then found another useful link (below).

It's a sorry day where you don't learn something new and what I learnt today was that flexible rubber hose comes in two different types with different "use by" dates. There's the two ply version (which I guess most people use) and a single ply version. The former, providing it doesn't show any obvious signs of deterioration, has a useful life of up to 10 years; the latter should be changed every five years and should have an expiry date marked on it as well as or instead of, a manufacturing date. Who knew.

And before someone starts on about stainless steel hose, I'm ignoring that for the sake of this post but it's covered in the accompanying document..

It shouldn’t have taken me kicking up a fuss about it to get another bulletin released.
I just saw it as farcical when as a Gas Safe Registered operative I could leave a 7 year old hose on a hire van but a caravan fitter was getting all excited about hoses being out of date at 5 years.
Here it is :

Gas hoses and assemblies ​ There is a standard covering gas hoses BS EN 16436-1 and a standard covering assemblies BS EN 16436-2. BS EN 16436-1 is for the hose and BS EN 16436-2 is for hoses when assembled with connections Hoses manufactured to BS EN 16436-1:2014 inc A3 2020 or assemblies manufactured to BS EN 16436-2 are classified in 3 classes depending on the pressure and temperature range they operate at. These details are shown below Class​ Marking​ Life cycle​ Max pressure​ Temperature range​ 1​ Expiry date​ 5 years after manufacturer​ 0.2 bar​ -20 to +70​ 2​ Production date​ Not specified​ 10 bar​ -30 to +70​ 3​ Production date​ Not specified​ 30 bar​ -30 to +70​ For Class 2 and 3 hose and assemblies there is no life cycle specified within the standards therefore the NCC recommends that Class 2 and 3 hoses are replaced after 10 years use.

Please ensure all gas hoses and assemblies offered for sale comply with either BS EN 16436-1 or BS EN 16436-2​
