Tests for chemical properties of aggregates - Part 1: Chemical analysis
This European Standard specifies procedures for the chemical analysis of aggregates. It specifies the reference procedures and, in certain cases, an alternative method which can be considered as giving equivalent results. Unless otherwise stated, the test methods specified in this standard may be used for factory production control, for audit tests or for type tests. This standard describes the reference methods used for type testing and in cases of dispute (and alternatives methods) for chemical analyses of aggregates. For the purpose of type testing and in cases of dispute only the reference method should be used. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the reference method has been established.
Prüfverfahren für chemische Eigenschaften von Gesteinskörnungen - Teil 1: Chemische Analyse
Diese Europäische Norm legt Verfahren für die chemische Analyse von Gesteinskörnungen fest. Sie legt die
Referenzverfahren und in bestimmten Fällen ein Alternativverfahren fest, dessen Ergebnisse als gleichwertig
zu denen des Referenzverfahrens angesehen werden.
Sofern nicht anders festgelegt, dürfen die in dieser Norm festgelegten Prüfverfahren für die werkseigene
Produktionskontrolle, für Audits oder für Erstprüfungen angewendet werden.
Diese Norm beschreibt für die chemische Analyse von Gesteinskörnungen die für die Erstprüfung und in
Streitfällen anzuwendenden Referenzverfahren (sowie Alternativverfahren). Für die Erstprüfung und in Streitfällen
sollte nur das Referenzverfahren angewendet werden. Für andere Zwecke, speziell im Rahmen der
werkseigenen Produktionskontrolle, dürfen andere Verfahren angewendet werden, sofern ein ausreichender
Zusammenhang zum Referenzverfahren nachgewiesen wurde.
Essais visant à déterminer les propriétés chimiques des granulats - Partie 1: Analyse chimique
La présente Norme européenne décrit les modes opératoires pour l’analyse chimique des granulats. Elle décrit les modes opératoires de référence et dans certains cas, une méthode alternative donnant des résultats similaires.
Sauf prescription, les méthodes d’essais décrits dans cette norme peuvent être utilisées pour le contrôle de fabrication en usine, pour des essais d’audit ou des essais de type.
Cette norme décrit les méthodes de référence utilisées pour les essais de type et en cas de litige (ainsi que les méthodes alternatives), pour l'analyse chimique des granulats. Pour les essais de type et en cas de litige, seule la méthode de référence sera utilisée. Lorsque d'autres objectifs sont visés, en particulier le contrôle de fabrication en usine, d'autres méthodes peuvent être utilisées, à condition que des corrélation appropriées avec la méthode de référence aient été établies.
Preskusi kemičnih lastnosti agregatov - 1. del: Kemijska analiza
Ta evropski standard določa postopke za kemijsko analizo agregatov. Določa referenčne postopke in v nekaterih primerih alternativno metodo, s katero lahko pridobimo enakovredne rezultate. Če ni navedeno drugače, se lahko preskusne metode iz tega standarda uporabljajo za kontrolo proizvodnje v obratu, zunanje kontrolne preskuse ali tipske preskuse. Ta standard opisuje referenčne metode, ki se uporabljajo za tipsko preskušanje in v primerih spora (in alternativnih metod) za kemijsko analizo agregatov. Za namen tipskega preskušanja in v primerih spora naj bi se uporabljala le referenčna metoda. Za druge namene, zlasti za kontrolo proizvodnje v obratu, se lahko uporabijo druge metode, če obstaja primerna delovna povezava z referenčno metodo.
