This Standard is applicable in Italy as long as the substitute, integrating and suppressive prescriptions contained in the General Part and in Sections I and III of Ministerial Decree dated 9 January are complied with. Some details of hollow core floors, for example the absence of nor- mal transverse reinforcement, make it necessary to apply some spe- cific rules in addition to ENV This is the General Standard addressing the needs for strength, behav- iour when installed and durability of structures made of reinforced and prestressed concrete.
It is extended to include the satisfaction of other interested parties: This is a most precise and detailed description of the production of concrete in order to assure the necessary durability as well as quality. This part supplies the principles and 10052 that supplement those cnf in ENV concerning prefabricated components and therefore also hollow core slabs. It promotes the adoption of a process approach to enhance customer satisfaction by meeting customer requirements.
It does not deal with specific fields but con- tains the values of safety coefficients approved by CEN-TC and the general principles of design valid 10025 for prefabricated compo- nents in general.
Reference to codes To obtain the Certificate of Conformity it will be indispensable for producers to adopt a Factory Production Control System.
General rules to value fire resistance of reinforced or prestressed con- crete structures are supplied by this standard. The new version of this Standard also applies to all cases concerning 100225. Reference 100225 codes Chapter 1 This indicates the objectives that a company must set itself in order to satisfy the Customer with continuity, to ensure company manage- ment that the pre-established quality standard has been reached and to assure the purchaser that the specified quality will be delivered.
This standard thus supplies the rules for special designs not contemplated by ENV andbut in perfect agreement with their principles of calcula- tion. This supplies a general basis for the design and building details of the structures of buildings partly or entirely constructed with pre- fabricated components.
Indeed, this Standard considers all operating stages of a job, from designing to dnr, erection and servicing once the structure has come into use. Reference to codes par.
European building Standards The geometric and strength characteristics of sections as well as calculating, designing, verifying and acceptance methods refer to European standards in force at the time this text is being written and are listed below.
The EC Conformity Mark will become obligatory for all building products as for all other products in circulation in countries belonging to the European Community. Reference to codes with concrete prefabricated structures and concerns the characteris- tics that producers of hollow core slabs must assure in order to respond to the essential requisites as defined by the Directive on Building.
At the moment it is not suitable for hollow core slabs. The effective application of the system aims to enhance not only customer satis- faction and product quality. Provision for hollow core floors with concrete topping. Ministerial Decree dated 3 December and Ministerial Memorandum no.
Minimum depth for hollow core floors without topping. Enviado por Leandro flag Denunciar. The certificate of conformity will be issued by national certification and inspection bodies which shall assess the compliance of the product with the European Product Standard by carrying out inspection and surveillance of production control.
