Hi all. Just wondered if anyone has any idea what form of Doctorate the writer in a reply to a question regarding CE marking of boilers holds. The title and name given by the writer is Dr Alan Blacker. He seems fairly authorative on the topic. Thanks.
A PM will do fine if there is any reason not to post a reply here

Hi Stan, I don't know who Dr Blacker is but I have sent in a reply to his letter taking issue with his statement that ALL commercial boilers must carry the CE mark. We've had this argument on the forum recently and the PER 1999 clearly states (to me anyway) that boilers between 0.1 and 2 litres capacity must NOT carry the CE mark. Also, his statement that Rule 6 of the Blue book (refering to the testing of commercial boilers) says that the boiler shall carry the CE mark is not correct. It actually states that the boiler shall carry the CE mark 'where appropriate'. It's about time this CE marking businness was clarified as there is obviously some confusion at the moment. I am quite happy to be proved wrong if it means the matter will get sorted once and for all  John |

John.
My question has arisen due to my involvement with the Southern Federation committee as the Editor of their newsletter. We, the committee, are concerned about the possible damage and confusion these statements can, and do have, when made in this manner. Obviously we do have to be a little conservative in our approach when trying to ascertain the credibility of these people that offer their 'opinions', hence my attempt to secure some background knowledge of this Dr Blacker.
We all agree this situation has rambled on for far too long and will be happy to see an end to it, believe me when I say it is not for want of trying!
If anyone else out there wants to or are able to provide some further information on this writer then I suggest they post their comments here for all to see.
This post by the way is not 'officially' through the Southern Federation, but on my own initiative, so bear with me if I seem a little careful on some aspects.
Thanks for your comments, I look forward to more from others.
Stan B.

He also says that a boiler without CE mark will never be legal, I understand they can be made legal with retrospective certification (at a price)
Why not ask on ME's own forum, David Clark seems to answer more there.

The DTi's own interpretation of the PER's are as follows:-
This Document is intended to help suppliers of pressure equipment and enforcement authorities to understand in general terms the main features of the 'PER'. It is informative and for guidance only and cannot act as a substitute for the regulations which constitute the law. The guide has no legal authority and is not an authoritive interpretation of the regulations, which is a matter for the courts
In short Dr Blacker, Baggo and anyone else can interpret these guidlines as they see it. They can comply as they see they should. Should anyone disagree through their enterpretation of the regs then they must go through the courts to see who is correct. An absolute legal minefield where only lawyers would gain anything. Until that happens, if you follow standards and procedures then you do comply, regardless of someone elses opinion. no one is dead right, and no one is absolutely wrong.

Dr Blacker's letter seems to contradict itself. At the start he says you can't pay anyone, including a fellow model engineer, to make you a boiler but at the top of page 509 he says buying from a fellow model engineer is alright!

It is such a good thing that we are all honest, and have not gone down the road of fake Boiler certificates and stamps on our boilers, as have various second hand cars from when they first started to appear on our roads.
To comply these days is very hard work so more and more clubs end passenger hauling etc, and most of us are happy to have one or two completed locos sat on display without a current certificate just to enjoy looking at them.

Does anyone know of a steam-powered space rocket or aircraft ever having been built, as mentioned in Model Engineer November-December 2009 - article by Mark de Barr, Marine and Steam Ltd? (I know Wallace & Grommit went to the Moon in one!)

Well, there has been a discussion about this at the last club meeting and there the same was said: "all commercial produced and sold boilers must carry a CE mark". I found it strange as I read those parts about small boilers also as "should not be marked". After all if the rule says you don't have to comply, then not complying is in fact compliant. But I'm going to read a bit more on it before bringing up the issue with the boiler tester. A plane has been build by Besler. You can even find a movie of it here: www.archive.org/details/BeslerCo1932 (there are trains in it as well so not completely off topic) And there is something on wikipedia about steam rockets but nothing spacegoing. |

Hi havoc
