Heating systems in buildings. Procedure for the preparation of documents for operation, maintenance and use. Heating systems not requiring a trained operatorWhat is BS EN 12171 Preparation of OM&U documents on heating systems about? BS EN 12171 is a European Standard that discusses the procedure for the preparation of documents for operation, maintenance and use, hereafter termed OM&U documents, of heating systems not requiring a trained operator. The main objective of BS EN 12171 is to ensure that the OM&U documents contain essential information to a minimum standardised level. BS EN 12171 specifies

It gives the specifications of the 10/700 μs combined wave generator
