Le présent document spécifie les méthodes d’examen des connaissances et compétences exigées d’un soudeur PE pour réaliser des raccordements de protection de l’assemblage sur site sur des systèmes monotubes ou bitubes isolés thermiquement pour les réseaux d'eau chaude et froide enterrés directement conformément à l’EN 13941‑1:2019 [17] et à l’EN 13941‑2:2019 [18].
L’application de ces méthodes spécifiées garantit que l’examen est réalisé selon un mode opératoire d’examen normalisé.
Le présent document s’applique aux processus suivants :
- travaux préparatoires pour la protection de l’assemblage ;
- assemblage et essai des éléments destinés aux systèmes de surveillance ;
NOTE Une formation complémentaire peut être nécessaire pour les systèmes de surveillance spéciaux.
- travaux préparatoires pour l’installation du système de protection de l’assemblage ;
- assemblage du système de protection de l’assemblage soudable ;
- exécution du soudage au gaz chaud et du soudage par extrusion au gaz chaud ;
- contrôle d’étanchéité des joints (essais d’étanchéité) ;
- isolation thermique de la protection de l’assemblage (injection de mousse PUR ou demi-gaine) ;
- étanchéité des trous de remplissage et de mise à l’évent (bouchons soudables) ;
- évaluation (non destructive) de la qualité d’installation globale du raccord de protection de l’assemblage.
