Langues : Anglais (eng) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique. L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1. C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple. Certification Ignifugeants Composé chimique utilisé pour réduire l'inflammabilité.

Intumescence (chimie) Métaux -- Revêtements protecteurs Index. décimale : 667.9 Revêtements et enduits Résumé : Intumescent coatings (lCs) are often used for protecting steel buildings during a fire when the structural, aesthetic, and architectural features of the structural members should be preserved. ICs form a thin protective layer on the steel surface, that if exposed to fire or elevated temperatures, expands in volume with a consequent reduction in density. Hence, the protective layer captures heat and protects the structural member from damage or elevated deformation. This reactive fire protection is designed using prescriptive tables, in which the IC thickness is chosen according to the required fire resistance, critical temperature, and section factor of the steel element. These tables are elaborated on the basis of the tests results according to the UNI EN 13381-8 standard, which is the reference for characterising reactive systems such as ICs. For its reactive nature, this fire protection has to be applied to the structure in a controlled manner, and it is good practice to verify its correct application by measuring thickness and adhesion in situ through regulated methods. The qualification process of IC systems in Italy can be realised through a voluntary certification within the scope of a European technical assessment or by means of a national technical assessment certificate that is mandatory. Ail these aspects related to qualification, assessment, and design of ICs are often ignored by both designers and manufacturers, especially in Italy. Therefore, this paper describes all the approaches, introducing the main technical differences, in order to provide a sort of guideline on the use of these reactive fire protections Note de contenu : - IC TECHNICAL SOLUTION : Inert phase - Transient phase - Steady phase - post-austenitisation phase - QUALIFICATION PROCESS : National qualification process - European qualification process - DESIGN AND CONTROL OF THE APPLICATION : OVERVIEW OF AVAILABLE CODES : Design and verification methods with a prescriptive-based approach - Design and verification methods with a performance-based approach - Control of IC application - Table 1 : Typical table for the prescriptive design of IC thickness - Table 2 : Essential characteristics and relative assessment methods for reactive coating systems according to EAD 350402-00-1106 En ligne : https://drive.google.com/file/d/13svCKQtaUCgP7PwWeePbKr0l2sOPihHv/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=37871 [article]
