Reference to codes par.
Producers of pre- fabricated components are involved. This standard thus supplies the rules for special designs not contemplated by ENV andbut in perfect agreement with their principles of calcula- tion.
Some details of hollow core floors, for example the absence of nor- mal 1005 reinforcement, make it necessary to apply some spe- cific rules in addition to ENV Provision for hollow core floors with concrete topping.
Reference to codes Chapter 1 This indicates the objectives that a company must cr itself in cnd 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 supplies a general basis for the design and building details of the structures of buildings partly or entirely constructed with pre- fabricated components. This is a most precise and detailed description of the production of concrete in order to assure the necessary durability as well as quality.
Indeed, this Standard considers all operating stages of a job, from designing to implementation, erection and servicing once the structure has come into use. 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. The new version of this Standard also applies to all cases concerning prefabrication.
Reference to codes To obtain the Certificate of Conformity 1002 will be indispensable for producers to adopt a Factory Production Control System. 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 also for prefabricated compo- nents in general.
dnr 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. Enviado por Leandro flag Denunciar.
General rules to value fire resistance of reinforced or prestressed con- crete structures are supplied by this standard. 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. 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.
This is a fundamental document for the analytical calculation of a structure’s resistance to fire.

Ministerial Decree dated 3 Crn and Ministerial Memorandum no. This is the General Standard addressing the needs for strength, behav- iour when installed and durability of structures made of reinforced and prestressed concrete. Minimum depth for hollow core floors without topping.
It is extended to include the satisfaction of other interested parties: The effective application of the system aims to enhance not only customer satis- faction and product quality. This part supplies the principles and rules that supplement those found in ENV concerning prefabricated components and therefore also hollow core slabs.
At the moment it is not suitable for hollow core slabs. 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. It promotes the adoption of a process approach to enhance customer satisfaction by meeting customer requirements.
