NF P04-002

Tolerances for building. Dimensions and positions. General specifications.

Il existe de nombreux documents techniques où figurent des spécifications pour les tolérances relatives aux dimensions des ouvrages de bâtiment et à la position des ouvrages et des bâtiments : - normes de produits ou de composants, où les valeurs des tolérances dimensionnelles sont généralement dépendantes des matériaux constitutifs, - Cahiers des Clauses Techniques, où les valeurs des tolérances dimensionnelles et de position, relatives aux principaux ouvrages (façades, planchers, cloisons ), sont fonction également de leur technologie ou mode de réalisation (béton coulé en place, maçonnerie, bois, métal...). Il est nécessaire que toutes ces valeurs de tolérances et leur mode de présentation constituent un ensemble cohérent. La présente norme a pour but de fournir un certain nombre de principes tendant à assurer cette cohérence.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
