New 8F out of China

If you want to import them you might as well test them yourself then you know that it has been done properly. The kit to do it is very simple and can't cost much to lash up. You can also sell second hand locos with new certificates.
Does this mean that any (unqualified) person can issue a new boiler certificate? I find that both surprising and more than slightly worrying.

edit - Stockers got in before me :bigsmile:.
 
This thread has been interesting to see the progression. UK laws are such that liability costs are substantial, this can now be seen in that some sellers/manufactures are not able to sell to the USA due to the high cost of insurance. This is a shame since this limits the sellers market size, Live steamers in the USA may or may not be very large at this time but with the availablity of more affordable models and the information available on the internet the size will certainly increase. It would be a shame/unfair if the UK sellers markets are limited due to the cost of insurance.
I really do not believe the USA is any greater a liability risk than the UK. Besides the cost of an overseas court case must be outragious. USA lawyers will take cases on the agreement of taking a percentage of the awarded monitary awards, but they will not take a case that is not expected to have a reasonable payoff because thay won't make enough money.
I would really like to hear lawsuit of a live steam seller who actually got sued from a USA customer.
The live steam products coming out of china are becoming if not already are very good quality, no doubt it will pass a hydrostatic test.

I saw a test to destruction on one of the US fora ages ago, very interesting as they thought the fittings would blow out first - in fact the main shell (drawn tube, as you say) split, at over 400psi though IIRC. That doesn't mean they shouldn't be tested or legally certified though!

I think it is the insurers who decide what level of competency they will accept for a tester - model engineering clubs usually have a designated tester who has satisfied them in terms of competency and method.
 
The situation in this thread is becoming clouded by supposition.

Under EEC rules all commercially produced pressure vessels must carry a test cert and a CE mark at point of first sale.

Any pressure vessel of less than 2 bar/ltrs does not require any further testing, even if sold secondhand/used. (that pretty well covers everything we use in this gauge)

Over-testing can actually damage a perfectly good boiler, which is why copper boilers on models (over 2 bar/ltrs) are now only hydraulically tested every 4 years, to 1.5 times their working pressure, though they do still have a steam test every 12-14 months.

Testers do not require any formal qualifications but Model Societies have a duty to appoint someone who is competent and with some relevent experience.

These regulations where last revised in 2008, in consultation with Midlands Fed of M.E.s, the Northeren Assoc of M.E.s, 7 1/4" Ggauge Society, and the Southern Fed of M.E.s, Ground Level 5" G Mainline Assoc, H.S.E. Model Steam Road Vehicles Soc, representatives of the trade a model maunfacturers, and the Royal, Sun Alliance Engineering representatives (which pretty much covers anyone with an interest). Further consultation is continuous, with regular meetings.
 
Bob G,

Does that mean that a .25 liter boiler needn't be tested if it sees less than 8 bars pressure, (that's 117.6 psi for those on this side of the pond)?
 
Correct. It only needs testing for initial sale if it's commercially built. Not if you build it for yourself not intending to sell it, and most boilers for this scale seem to only require around 50psi max working pressure anyway.

The risks from the boilers in our scale is so small, it is just the US law suit culture than has come over here that is to blame.

I heard it all started in the UK. But I think Political Correctness is a USA invention exported elsewhere, of which I am sad to say.

If you write to any of the organisations listed above they will send you a copy of the "Blue Book". 'The Examination & Testing of Miniature Steam Boilers' (revised edition, 2008).

I think Steve if you read it thoroughly, boilers even under 2 bar/ltrs still require a CE mark if produced within the EEC. That's as I understand it anyway. I have also received notification today that the lower gas tank limit has been raised to 250ml from 180ml, before requiring certification. As you say it all makes for very dry reading.
