Preparation of steel substrates before application of paints and related products - Test methods for non-metallic blast-cleaning abrasives - Part 4: Assessment of hardness by a glass slide test (ISO 11127-4:2020)

This document specifies a method of assessing of whether a non-metallic blast-cleaning abrasive has a
minimum hardness of 6 on Mohs' scale.
This document is a part of the ISO 11127 series dealing with the sampling and testing of non-metallic
abrasives for blast-cleaning.
The types of non-metallic abrasive and requirements on each are contained in the ISO 11126 series.
The ISO 11126 and ISO 11127 series have been drafted as a coherent set of International Standards on
non-metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.
NOTE The test described in this document is a pass/fail test and is not a method for the accurate
determination of hardness.

Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen - Prüfverfahren für nichtmetallische Strahlmittel - Teil 4: Abschätzung der Härte durch Vergleich mit Glasscheiben (ISO 11127-4:2020)

Dieses Dokument legt ein Verfahren zur Abschätzung fest, ob ein nichtmetallisches Strahlmittel eine Mindesthärte von 6 nach der Mohsskala aufweist.
Dieses Dokument ist ein Teil der Reihe ISO 11127, welche die Probenahme und die Prüfung von nichtmetallischen Strahlmitteln behandelt.
Die verschiedenen Arten nichtmetallischer Strahlmittel und Anforderungen an diese sind in der Reihe ISO 11126 enthalten.
Die Normenreihen ISO 11126 und ISO 11127 wurden als zusammengehöriger Satz von Internationalen Normen über nichtmetallische Strahlmittel ausgearbeitet. Angaben zu allen Teilen der beiden Normenreihen sind in Anhang A enthalten.
ANMERKUNG Das in diesem Dokument beschriebene Prüfverfahren, ist eine ja/nein-Prüfung (pass/fail test). Es ist kein Prüfverfahren, mit dem die Härte genau bestimmt werden kann.
