This VGB-Standard on construction and installation supervision in the manufacturing and assembly of water-tube boilers and associated systems in thermal power plants has been revised in intensive discussions between the Fachverband Dampfkessel-, Behälter- und Rohrleitungsbau e.V. (FDBR – Association of Steam Boiler, Pressure Vessel and Piping Manufacturers) and VGB PowerTech e.V. (VGB) and has been endorsed by the FDBR. The purpose of this VGB-Standard is to assist in securing the quality expected and required by the plant owner or operator as the customer.

The market situation is compelling contractors (manufacturers and suppliers) to offer their products and services more and more cheaply. Experience shows that cost savings in manufacture are essentially implemented at the expense of quality. Stipulation of quality assurance measures by the customer, from the tendering process to final inspection, is therefore essential. This standard is a suitable basis for achievement by customers and contractors of the required quality.

This standard covers the processes from ordering to placing on the market of the water-tube boiler and its system components. Placing on the market is completed with the commissioning test to Section 15 of the German Ordinance on Industrial Safety and Health. The process of commissioning is not covered by this standard.
