The declaration of conformity of home systems: definition, when required, obligations, penalties
The Ministerial Decree 37/2008, evolution of the Law 46/90, governs the construction, maintenance, and design of systems in buildings. The declaration of conformity of the systems is a document issued by a company authorized following the installation or modification of a plant. If the "compliance" is non-existent it is possible to proceed with the DIRI (declaration of conformity). The decree describes the obligations and penalties for the owner deeds and renovations.
Declaration of Conformity
At the end of the work, the official of the company that has changed or installed the system, issue the customer the declaration of conformity. This document is composed by the report of the materials used, the forms attached in the decree and the design drawings (if applicable).
In the event that the 'intervention modify an existing installation, the certificate relates only partly modified but must also take into account the functionality and security of all del'impianto.

- And 'necessary to establish new utilities (gas, electricity, water)
- And 'necessary to obtain the certificate of occupancy
- It is no longer necessary to attach to the deed (but you should specify if the plant is "under")

Declaration of Conformity DIRI
In the case of the certificate of conformity is no longer available, you can replace it with a Declaration of Conformity called "DIRI" (facsimile Diri) only if the plants were established before the entry into force of Decree 37/08.

The declaration must be supported by assessments and surveys useful to verify the compliance of the installation with the legislation.
When a plant can be considered a norm?
The decree does not require to adapt the non-compliant plants but discipline interventions on existing plants and construction of new ones. To consider an installation in accordance need to define what epoch was made or modified.
If the premises have been made before the 'entry into force of Decree 37/2008 (March 27, 2008) are considered according to whether, when they were made, responding to the existing provisions at that time. If you no longer available the certificate of conformity is possible to replace it with the Declaration of Compliance prepared by an authorized installation engineer with experience in the field for at least 5 years.
In particular, an electrical system made before March 13, 1990 is considered to be under if equipped with isolation and protection against overcurrent places to 'origin and plant protection with GFCI.
