Temporary works equipment - Part 3: Load testing

This standard specifies general rules for: - testing; - documentation of test results and - evaluation of test results in the field of (non mechanical) temporary works items.

Temporäre Konstruktionen für Bauwerke - Teil 3: Versuche zum Tragverhalten

Diese Norm legt die Regeln für Belastungsversuche, Dokumentation und Auswertung der Versuchsergebnisse im Bereich der nichtmaschinenbaumäßigen temporären Konstruktionen für Bauwerke fest.
ANMERKUNG   Diese EuropäischeNorm sollte allen Arbeitsgruppen des CEN/TC 53 als Grundlage für Normen dienen, welche Versuche beinhalten. Diese Norm enthält allgemeine Regeln; dabei wird vorausgesetzt, dass bei Bedarf spezielle Anforderungen in der jeweiligen Norm festgelegt werden, z. B. die Einzelheiten von Prüfverfahren.

Equipements temporaires de chantiers - Partie 3: Essais de charges

Cette Norme européenne précise les règles à appliquer pour les essais de charge effectués sur les équipements temporaires de chantier de nature non-mécanique, ainsi que pour la documentation et l'évaluation des résultats de ces essais.
NOTE   La présente norme s'adresse à tous les groupes de travail du CEN/TC53 et constitue un document de base pour les différentes normes portant sur les essais. La présente norme se limite aux règles générales ; dans tous les cas où des exigences particulières devront être définies (procédure d'essai à préciser, par exemple), il est entendu que ces exigences feront l'objet d'une norme spécifique.
