SUPPLEMENT TO THE EXAMINATION & TESTING OF MINIATURE STEAM BOILERS

(Revised Edition 2012)

INCLUDING THE SAFETY OF LPG TANKS.

The Supplement document has been issued for use by member Societies of the Northern

Association of Model Engineers and the Southern Federation of Model Engineering Societies and is

the Supplement to Boiler Test Code BTC 2012 commonly known as the Green Book. The Issue 1

August 2013 updates and replaces the document previously issued by the Northern Association of

Model Engineers and all previous issues of this document should be destroyed.

Primarily the document describes a Code of Practice to ensure the Safety of Liquid

Petroleum Gas (LPG) Tanks with an internal volume not exceeding 250 cubic centimetres for use

with small boilers. The recording of the relevant Safeguard Test Data, for members of the Southern

Federation only, is to be included on the Certificate of Annual Inspection and Steam Test for Boilers

below 3.00 bar litres. This will require a minor modification to the current Certificates already issued

as shown on the sample herewith. The reprint certificates already contain the modified format.

The minor changes to the Certificate are in Box B.

Repairs etc…. insert (note on the reverse)

First blank line insert Gas Tank Serial Number. e.g. SF 123-100123

For members who manufacture their own Gas Tanks, which will require an Initial Hydraulic

Test to the prescribed test pressure related to the intended gas or mixture of gases, an appropriate

Certificate of Test and Initial Inspection of a Liquid Petroleum Gas Tank will be issued by the

Southern Federation through the web site for completion by the Society Boiler Inspector.
