VGB R 109:2014

The VGB directive R 109 'Material specification for components under pressure in fossil-fired power plants' applies to the steam boiler assembly and pipelines of the water/ steam circulation. It shall clearly determine the delivery contract and the subsequent contract administration between customer, manufacturer and material manufacturer or supplier and thus enable a rationalisation of the order and order processing. The material specification provides a collection of experiences and recommendations compiled to the best of knowledge and coordinated between the parties involved in the construction of the power plant. It intends to summarise the requirements on material manufacturers or suppliers and on the provision of materials for pressure equipment usually used in the 600 °C power plant generation to facilitate the order basis between the parties involved. Regulations from data sheets and directives exceeding the requirement of the EN standards, were textually integrated to a large extent.
The Guideline was revised and the chapter 14 'Requirements on filler material' added.

The Guideline is bilingual (German/English).
