Ausferritic (bainitic) cast iron: Harmonization of international standard ISO 17804 in application to the conditions of Belarus

The experience of the Physico-technical Institute (PhTI) National Acdemy Sciences Belarus in harmonization international standard ISO 17804 (Founding – Ausferritic spheroidal graphite cast irons Classification) and development Belorussian analogue STB is described. reasons for choice austempered ductile iron (ADI) as an object are presented: it most promising comparison with gray classical iron. work procedure on described: how to include task into State Plan standardization, specificity translation text, peculiarities state organizations responsible approbation standards such Standardization Certification (BelGISS) Committee Standards (Gosstandart), writing a summary external reviews, working critical comments from potential users. It outlined that any foreign does not exists independently but closely connected at least 10 20 other standards. Thus, necessitates coordination sometimes even handbooks by adding annexes main text. importance proper status outlined: identical (ID) or modified (MOD). Developing prestigious difficult because requires all referenced standards, which very labor-consuming procedure. argued suitable ‘intermediate’ variant: adopting authentic text (in high-quality translation) reflecting national this area. As result, harmonized developed which, first time Belarus, standardize tensile strength 800 MPa combination elongation % 1400 1 irons. annual demand ADI estimated about 10,000 ton. shown where 60 industrial enterprises have foundry almost every engineering plant has heat-treatment shop, (ADI), features high strength, can successfully compete rolled steel certain applications.
