(Main)Characterization of waste - Static test for determination of acid potential and neutralisation potential of sulfidic waste
Characterization of waste - Static test for determination of acid potential and neutralisation potential of sulfidic waste
This European standard specifies methods to determine the potential of sulfide bearing materials for the formation of acidic drainage. Specified are methods for determining both the acid potential (AP) and the neutralisation potential (NP) of the material. From these results the net neutralisation potential (NNP) and the neutralisation potential ratio (NPR) are calculated.
This European standard is applicable to all sulfide bearing wastes from the extractive industries excluding wastes which will have pH < 2 in the initial step of the procedure described in 8.2.3.
Charakterisierung von Abfällen - Statische Prüfung zur Bestimmung des Säurebildungspotenzials und des Neutralisationspotenzials von sulfidhaltigen Abfällen
Diese Europäische Norm legt Verfahren zur Bestimmung des Potenzials von sulfidhaltigen Materialien zur
Säurebildung fest. Festgelegt werden Verfahren zur Bestimmung sowohl des Säurebildungspotenzials
(en: acid potential, AP) als auch des Neutralisationspotenzials (en: neutralisation potential, NP) des Materials.
Aus diesen Ergebnissen werden das Nettoneutralisationspotenzial (en: net neutralisation potential, NNP) und
der Pufferungsquotient (en: neutralisation potential ratio, NPR) berechnet.
Diese Europäische Norm ist auf sämtliche sulfidhaltigen Abfälle aus der mineralgewinnenden Industrie
anwendbar, mit Ausnahme von Abfällen, deren pH-Wert beim ersten Schritt des in 8.2.3 beschriebenen
Verfahrens kleiner als 2 ist.
Caractérisation des déchets - Essai statique pour la détermination du potentiel de génération d'acide et du potentiel de neutralisation des déchets sulfurés
La présente Norme européenne spécifie des méthodes permettant de déterminer le potentiel des matériaux sulfurés à former des eaux de drainage acides. Les méthodes spécifiées permettent de déterminer à la fois le potentiel de génération d’acide (AP) et le potentiel de neutralisation (NP) du matériau. A partir de ces résultats, le potentiel de neutralisation net (NNP) et le rapport de potentiel de neutralisation (NPR) sont calculés.
La présente Norme européenne est applicable à tous les déchets sulfurés de l’industrie extractive, à l’exclusion des déchets qui auront un pH inférieur à 2 lors de l’étape initiale du mode opératoire décrit en 8.2.3.
Karakterizacija odpadkov - Statični preskus za določevanje kislinske in nevtralizacijske kapacitete odpadkov, ki vsebujejo sulfid
Ta evropski standard določa metode za določevanje kapacitete materialov, ki vsebujejo sulfid, za tvorbo kisle drenaže. Opredeljene so metode za določevanje kislinske (AP) in nevtralizacijske kapacitete (NP) materiala. Iz teh rezultatov se računa neto nevtralizacijska kapaciteta (NNP) in razmerje nevtralizacijske kapacitete (NPR). Ta evropski standard se uporablja za vse odpadke ekstraktivne industrije, ki vsebujejo sulfid, razen odpadkov, katerih pH v prvi fazi postopka, opisanega v 8.2.3, znaša < 2.

To carry out a more precise assessment of the acid generation potential and buffering capacity mineralogical information is required. A number of special cases can be identified: e.g. presence of sulfate (e.g. gypsum), non-acid producing sulfides or carbonates with no buffering capacity. Acid neutralisation behaviour as obtained by other methods can provide additional information in circumstances of uncertainty.
