Qu\u00e8 \u00e9s la ISO 23932?
La norma ISO 23932, sobre Enginyeria de seguretat contra incendis, proporciona les bases conceptuals i metodol\u00f2giques per aplicar el disseny prestacional en seguretat contra incendis. Aquesta norma facilita un enfocament m\u00e9s flexible, t\u00e8cnic i adaptat a les caracter\u00edstiques reals dels edificis i els seus usos, en contraposici\u00f3 al disseny purament prescriptiu.<\/p>\n\n\n\n
ISO 23932 tracta aspectes com la formulaci\u00f3 d\u2019objectius de seguretat, la identificaci\u00f3 d\u2019escenaris d\u2019incendi, la definici\u00f3 de criteris d\u2019acceptaci\u00f3 i l\u2019avaluaci\u00f3 de les solucions projectades. La seva aplicaci\u00f3 permet demostrar que un disseny compleix els nivells de seguretat adequats, fins i tot quan s\u2019aparta de les exig\u00e8ncies normatives tradicionals.<\/p>\n\n\n\n
Un dels eixos clau de la norma \u00e9s la definici\u00f3 dels escenaris dincendi de disseny, que han de ser representatius, realistes i justificables, i que constitueixen la base per a la simulaci\u00f3 del comportament del foc, la propagaci\u00f3 de fum i els temps devacuaci\u00f3. Aix\u00ed mateix, s\u2019emfatitza la necessitat d\u2019utilitzar models validats (com CFD o models zonals), i de considerar tant el temps disponible d\u2019evacuaci\u00f3 (ASET) com el temps requerit (RSET).<\/p>\n\n\n\n
ISO 23932 tamb\u00e9 destaca la import\u00e0ncia de documentar de forma rigorosa el proc\u00e9s de disseny prestacional, assegurant la tra\u00e7abilitat, justificaci\u00f3 t\u00e8cnica i transpar\u00e8ncia de l\u2019enfocament utilitzat. Aquesta norma \u00e9s especialment rellevant per a edificis complexos, innovadors o amb usos no convencionals, on els m\u00e8todes prescriptius s\u00f3n insuficients o inadequats.<\/p>\n\n\n\n
Preguntes freq\u00fcents sobre la ISO 23932
On es pot trobar el marc metodol\u00f2gic del disseny prestacional d’incendis?
La ISO 23932 \u00e9s una norma que estableix els principis generals del disseny prestacional d\u2019incendis (performance-based fire safety design). En concret, proporciona un marc metodol\u00f2gic per analitzar i justificar la seguretat contra incendis basant-se en el comportament real del foc, les persones i l\u2019edifici, i no nom\u00e9s en requisits prescriptius.<\/p>\n\n\n\n
La ISO 23932 serveix per estructurar correctament un estudi de disseny prestacional, definint com identificar objectius de seguretat, escenaris dincendi, criteris dacceptaci\u00f3 i m\u00e8todes dan\u00e0lisi. Per tant, \u00e9s una refer\u00e8ncia clau per a enginyeria dincendis avan\u00e7ada i projectes complexos.<\/p>\n\n\n\n
Tot i que no \u00e9s obligat\u00f2ria, es fa servir com a refer\u00e8ncia t\u00e8cnica clau per estructurar correctament el disseny prestacional d\u2019incendis.<\/p>\n\n\n\n
\u00c9s obligat\u00f2ria la ISO 23932 a Espanya?
No, la ISO 23932 no \u00e9s obligat\u00f2ria. Tot i aix\u00f2, s\u2019utilitza com a norma de refer\u00e8ncia t\u00e8cnica quan es plantegen solucions alternatives al CTE DB-SI. A la pr\u00e0ctica, aporta credibilitat i rigor davant administracions i serveis de bombers.<\/p>\n\n\n\n
La ISO 23932 no substitueix cap normativa nacional. M\u00e9s aviat, s\u2019utilitza com a complement t\u00e8cnic per justificar solucions equivalents o millorades, mentre que el CTE i el RIPCI segueixen sent de compliment obligat.<\/p>\n\n\n\n
A quins tipus d’edificis \u00e9s m\u00e9s recomanable el PBD?
El disseny prestacional (PBD) \u00e9s recomanable aplicar-lo especialment a:<\/p>\n\n\n\n
Naus industrials i log\u00edstiques de gran al\u00e7ada o superf\u00edcie.
Sitges i magatzems automatitzats.
Aparcaments tancats complexos.
Centres comercials i estadis.
Estacions de ferrocarril.
Edificis patrimonials.
Instal\u00b7lacions amb zones ATEX o processos cr\u00edtics.
Edificis singulars o rehabilitacions complexes, on l\u2019enfocament prescriptiu no \u00e9s suficient o no resulta viable t\u00e8cnicament o econ\u00f2micament.
En aquests escenaris, aplicar nom\u00e9s criteris prescriptius sol portar a sobredimensionar sistemes o directament a bloquejar el projecte.<\/p>\n\n\n\n
Per qu\u00e8 serveixen els models validats (com CFD o models zonals)?
Els models validats, com ara CFD o models zonals, s\u00f3n essencials en el disseny prestacional d\u2019incendis. Permeten predir amb rigor l\u2019evoluci\u00f3 del fum, les temperatures i la visibilitat, aportant dades fiables per justificar solucions alternatives, optimitzar mesures de seguretat i garantir el compliment dels objectius de seguretat contra incendis.<\/p>\n\n\n\n
Qui ha d’aplicar la ISO 23932?
L\u2019ha d\u2019aplicar un t\u00e8cnic especialitzat en enginyeria d\u2019incendis, tant de l\u2019enginyeria com de la certificadora que en faci la revisi\u00f3 per tercera part, amb capacitat per definir escenaris, interpretar resultats i assumir la responsabilitat t\u00e8cnica de l\u2019estudi.<\/p>\n","protected":false},"excerpt":{"rendered":"
