The Amber document status indicator indicates that some caution is needed when using this document – it is either: Document Status Indicators The Green document status indicator indicates that the document is: Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards.
The welding is classified considering the admissible levels of defeats that it can have during the manufacturing process.
The aim is to offer to the designers a summary of the main specifications that need for a definition of a welding process such as: Levels refer to production quality and not to fitness for purpose of 2587 product.
Four classes are defined and they are equivalent to the defeat levels cfr.
The norm EN EN A structure can include several execution classes. B the ENexecution classes may apply to the whole structure or to a part of the structure or to specific details.
The following table is an extract from the EN ISO and shows an example of the acceptable defeats in the weld for the different quality levels.
