Equivalences between different standardized specifications of materials are usually established with respect to their main chemical and mechanical properties. However, the technological requirements described by equivalent specifications sometimes exhibit significant differences between them. Additionally, publications of key importance about the influence of the chemical composition on the mechanical behaviour of material have not often been taken into account. The aim of this work is to develop a decision tool to distinguish between two different specifications based in the quantification of the efficacy of technological requirements. We have developed a deterministic algorithm that provides a quantifiable value of the efficacy of each requirement, which has been defined as Stringency Level. This methodology has been applied to SA 508 Class 3 nuclear specification included in ASME B&PV American Code and DIN 20MnMoNi55 as described by KTA German Nuclear Safety Rules. Finally, it has been concluded that DIN specification is more suitable than SA specification to be used in the manufacture of the primary loop for PWR-Type Nuclear Power Plants. De forma habitual, se establecen equivalencias entre distintas especificaciones normalizadas de materiales con respecto a sus principales propiedades qu\u00edmicas y mec\u00e1nicas. Sin embargo, los requisitos tecnol\u00f3gicos descritos por las especificaciones equivalentes, a menudo presentan diferencias significativas. Asimismo, en determinadas ocasiones, no se han tenido en cuenta algunos trabajos clave sobre la influencia de la composici\u00f3n qu\u00edmica en el comportamiento mec\u00e1nico del material. El objetivo del presente trabajo es el desarrollo de una herramienta de decisi\u00f3n sobre dos especificaciones normalizadas diferentes, basada en la cuantificaci\u00f3n de la eficacia de requisitos tecnol\u00f3gicos. Para ello, hemos desarrollado un algoritmo determinista que permite obtener un valor cuantificable definido como Nivel de Severidad. Esta metodolog\u00eda ha sido aplicada sobre especificaciones de materiales destinados al sector nuclear, como son las especificaciones SA 508 Clase 3 del c\u00f3digo de fabricaci\u00f3n americano ASME B&PV y la especificaci\u00f3n DIN 20MnMoNi55 descrita por las normas de seguridad nuclear alemanas KTA. Finalmente, se ha concluido que la especificaci\u00f3n DIN es m\u00e1s id\u00f3nea para su empleo en la fabricaci\u00f3n del circuito primario de una central nuclear tipo PWR… See all…<\/strong><\/span><\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
