Metallic powders - Determination of acid-insoluble content in iron, copper, tin and bronze powders (ISO 4496:2017)

ISO 4496:2017 specifies methods for determining, in iron, copper, tin and bronze powders, the approximate content of non-metallic materials which are insoluble in the ordinary mineral acids.
The insoluble matter referred to is generally considered to be acid-insoluble silica and silicates, carbides, alumina, clays or other refractory oxides which are either present in the raw material from which the powders are manufactured or introduced during the manufacturing process.

Metallpulver - Bestimmung der säureunlöslichen Bestandteile in Eisen-, Kupfer-, Zinn- und Bronzepulvern (ISO 4496:2017)

Dieses Dokument legt Verfahren zur Bestimmung des genäherten Gehaltes an nicht-metallischen Bestandteilen in Eisen-, Kupfer-, Zinn- und Bronzepulvern fest, die in den üblichen Mineralsäuren nicht löslich sind.
Zu unlöslichen Bestandteilen, die hier behandelt werden, rechnet man allgemein säureunlösliche Kieselerde und Silikate, Karbide, Tonerde, Ton und andere stabile Oxide, die entweder im Ausgangsstoff, aus dem die Pulver hergestellt werden, bereits vorhanden sind oder während des Herstellungsprozesses eingebracht werden.

Poudres métalliques - Détermination de la teneur en insolubles dans les acides pour les poudres de fer, de cuivre, d'étain et de bronze (ISO 4496:2017)

ISO 4496:2017 spécifie des méthodes pour déterminer, dans les poudres de fer, de cuivre, d'étain et de bronze, la teneur approximative en éléments non métalliques qui sont insolubles dans les acides minéraux courants.
Par éléments insolubles, on entend généralement des composés tels que la silice et les silicates, les carbures, l'alumine, les argiles ou autres oxydes réfractaires qui peuvent être soit présents dans le matériau avec lequel on fabrique les poudres, soit introduits en cours de fabrication.

Kovinski prah - Določevanje netopne kisline železa, bakra, kositra in bronovega prahu (ISO 4496:2017)

Ta dokument določa metode za določevanje netopne kisline železa, bakra, kositra in bronovega prahu,
približno vsebnost nekovinskih materialov, ki so netopni v navadnih mineralnih kislinah. Navedena netopna snov je običajno v kislini netopen silicijev dioksid in silikati, karbidi, glinice, gline ali drugi ognjevzdržni oksidi, ki so bodisi prisotni v surovini, iz katere se prah proizvaja, bodisi se uvedejo med proizvodnim postopkom.
