TY - RPRT A1 - Kannengießer, Thomas T1 - List of questions relating to the revision of ISO 3690 regarding the acceptance of the carrier gas hot extraction method T2 - IIW Doc. II-A-151-04 N2 - Is it reasonable to restrict ISO 3690 any longer to the determination of the weld metal hydrogen content of ferritic steel? In what respect is the determination of the content of the diffusible and of the total hydrogen content, respectively, (still) merely a research task (supermartensite, duplex materials, austenite, magnesium, aluminium), or is there actually a demand in industry and is there already a first cause for monitoring in view of damage prevention, respectively? Is there a need, arising from the development of materials and filler materials and from their intended applications, for more extensive standards dealing with hydrogen analyses for these materials? Which parts of ISO 3690 could also be applied to any other metallic material/filler material, if necessary, and where would a complete alteration be required, respectively?
