Armourstone - Part 2: Complementary information and test methods

This document specifies sampling and test methods for natural, manufactured and recycled aggregates for use as armourstone. This document specifies the reference methods to be used for type testing and in case of dispute where an alternative method has been used. For other purposes, in particular factory production control, it allows for other methods to be used provided that an appropriate working relationship with the test method has been established. This document provides non-contradictory complementary information that can be of use when producing or purchasing armourstone produced according to harmonised standard prEN 13383-1:2021.
NOTE   prEN 13383-1:2021 is also intended to be read in conjunction with the Construction Products Regulations.

Wasserbausteine - Teil 2: Ergänzende Informationen und Prüfverfahren

Dieses Dokument legt die Probenahme und Prüfverfahren für natürliche, industriell hergestellte und wiederaufbereitete Gesteinskörnungen für die Verwendung als Wasserbausteine fest. Dieses Dokument legt die Referenzverfahren fest, die für die Erstprüfung und in Streitfällen, in denen eine alternative Methode verwendet wurde, anzuwenden sind. Für andere Zwecke, speziell im Rahmen der werkseigenen Produktionskontrolle, dürfen andere Verfahren angewendet werden, sofern ein ausreichender Zusammenhang mit den Referenzverfahren nachgewiesen wurde. Dieses Dokument enthält eindeutige ergänzende Informationen, die bei der Herstellung oder dem Kauf von Wasserbausteinen, die in Übereinstimmung mit der harmonisierten Norm prEN 13383-1:2021 hergestellt wurden, von Nutzen sein können.

Enrochements - Partie 2 : Informations complémentaires et méthodes d’essai

Le présent document spécifie des méthodes de prélèvement et d’essai pour les granulats naturels, artificiels et recyclés destinés à être utilisés comme enrochement. Il spécifie les méthodes de référence devant être utilisées pour les essais de type et en cas de litige, lorsqu’une méthode alternative a été utilisée. À d’autres fins, en particulier pour la maîtrise de la production des granulats, il permet d'établir autres méthodes pouvant être utilisées sous réserve qu’une corrélation appropriée avec la méthode d’essai ait été établie. Le présent document fournit des informations complémentaires non-contradictoires qui peuvent être utilisées lors de la fabrication ou de l’achat d’enrochements produits selon la norme provisoire harmonisée prEN 13383-1:2021.
NOTE   La prEN 13383-1:2021 est également destinée à être lue conjointement avec la réglementation sur les produits de construction.

armourstone designation with a nominal lower and upper limit
Note 1 to entry: This designation accepts the presence of undersize and oversize pieces of armourstone.
3.1.2
nominal lower limit
mass or sieve size in a grading below which the armourstone pieces are considered to be undersized
3.1.3
nominal upper limit
mass or sieve size in a grading above which the armourstone pieces are considered to be oversized
3.1.4
coarse grading
designation of grading with a nominal upper limit defined by a sieve size ≥ 90 mm and ≤ 250 mm
3.1.5
light grading
designation of grading with a nominal upper limit defined by a mass ≥ 40 and ≤ 300 kg
3.1.6
heavy grading
designation of grading with a nominal upper limit defined by a mass > 300 kg
3.1.7
fragment
aggregate pieces in the finest fraction of coarse gradings or the lightest fraction of light and heavy
gradings for which the particle size distribution or mass distribution requirements apply
Note 1 to entry: For further information on grading, see pr EN 13383-1:2021, 4.1.1.
3.1.8

sampler
individual or a number of individuals working as a team, or an organisation, taking samples on a routine
