Grupos de materiales (ISO/TR 15608)
Consulta aquí qué significa cada grupo o subgrupo de material. El desplegable "Grupo de material base" del certificado WPQ solo permite elegir grupos de Acero (los mismos que ya tenía el programa original); el resto de familias se incluyen solo como referencia. Las descripciones están en el idioma original de la norma (inglés).
