Unshaped refractory products - Part 3: Characterization as received

This standard specifies the methods for the characterization of unshaped refractory materials as received and for checking the homogeneity of a delivery of a product. It is applicable to castables (dense and insulating), gunning materials and mouldables, as defined in ENV 1402-1. Note: A check list of appropriate tests is given in annex A.

Ungeformte feuerfeste Erzeugnisse - Teil 3: Prüfung im Anlieferungszustand

Dieser Teil dieser Europäischen Norm legt die Verfahren für die Prüfung ungeformter feuerfester Erzeugnisse im Anlieferungszustand und für die Prüfungen der Gleichmäßigkeit von Lieferungen eines Erzeugnisses fest. Er ist anwendbar für die in EN 1402-1 festgelegten Feuerbetone (dichte Feuerbetone und wärmedämmende Feuerbetone), feuerfesten Spritzmassen und formbare Massen.
ANMERKUNG   Eine Übersicht geeigneter Prüfungen ist im Anhang A aufgeführt.

Produits réfractaires non façonnés - Partie 3: Caractérisation à l'état de réception

La présente partie de cette Norme européenne spécifie les méthodes pour la caractérisation des matériaux réfractaires non façonnés dans l'état de réception et pour le contrôle de l'homogénéité d'une livraison de produits. Elle s'applique aux bétons (denses et isolants), aux matériaux projetables et aux matériaux moulables, tels que définis dans le prEN 1402-1.
NOTE   La liste des essais appropriés est donnée dans l'annexe A.

EN 1402-3:2003 (E)54 SamplingTake samples in accordance with the guidance given in EN 1402-2 and prepare the quantities required by eachindividual determination.5 Determination of chemical composition5.1 Preparation of test sampleFor ramming materials supplied wet, dry the samples (see clause 4) in accordance with 6.5.1. For all samples,reduce the amount by coning and quartering and grind to the particle size required for chemical analysis.NOTEThe methods of chemical analysis used include the determination of loss on ignition.5.2 Alumina-silica productsDetermine the chemical composition either in accordance with EN 955-2 (wet methods), EN ISO 12677 (X-rayfluorescence (XRF) analysis) or ENV 955-4 (Analysis by Flame Atomic Absorption Spectrometry (FAAS) andInductively Coupled Plasma Emission Spectrometry (ICP)).NOTEFor products containing chrome, prEN 955-3 can be used in place of EN 955-2.Report the method used.5.3 Basic productsDetermine the chemical composition in accordance with EN ISO 10058 (wet methods), prEN 955-3 for productscontaining chrome or EN ISO 12677 (XRF analysis).Report the method used.5.4 Special productsAs no standard is currently available for the determination of materials other than the alumina-silica or basic series,the chemical composition shall be determined according to me
