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 11127-4:1993)

The procedure includes examining a small quantity of the sample under the microscope and, if grains of different colours or diameter are present, selecting a few grains of each, placing the selected grains between two glass microscope slides and, whilst applying pressure, slowly moving one slide over the other with a reciprocating motion for 10 s, examining the glass surfaces for scratches. The object of the method is to assess whether the sample has a minimum hardness of 6 on Mohs' scale. Annex A gives information on the international standards series for non-metallic blast-cleaning abrasives ISO 11126 and ISO 11127.

Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen - Prüfverfahren für nichtmetallische Strahlmittel - Teil 4: Abschätzung der Härte durch Vergleich mit Glasscheiben (ISO 11127-4:1993)

Dieser Teil von ISO 11127 legt ein Verfahren fest zur Abschätzung, ob ein nichtmetallisches Strahlmittel eine Mindesthärte von 6 nach der Mohlsskala auweist.

Préparation des subjectiles d'acier avant application de peintures et de produits assimilés - Méthodes d'essai pour abrasifs non métalliques destinés à la préparation par projection - Partie 4: Evaluation de la dureté au moyen d'un essai à la lame de verre (ISO 11127-4:1993)

La présente norme est l'une des parties de l'ISO 11127, qui traite de l'échantillonnage et des essais des abrasifs non métalliques destinés à la préparation par projection. Les types d'abrasifs non métalliques et les prescriptions relatives à chacun figurent dans les différentes parties de l'ISO 11126. Les séries des normes ISO 11126 et ISO 11127 constituent une série cohérente de normes internationales sur les abrasifs non métalliques destinés à la préparation par projection. Des informations sur toutes les parties des deux séries sont données dans l'annexe A. La présente partie de l'ISO 11127 prescrit une méthode pour déterminer si un abrasif non métallique destiné à la préparation par projection a une dureté minimale de 6 sur l'échelle de Mohs.
NOTE 1 L'essai décrit dans la présente partie de l'ISO 11127 est un essai tout ou rien et n'est pas une méthode pour la détermination précise de la dureté.

BS0 11127-4:1993[E) Foreword ISO (the lnternational Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote, International Standard ISO 11127-4 was prepared by Technical Committee lSO/bC 35, Paints and varnishes, Subcommittee SC 12, Preparation of steel substra tes be fore application o f paints and rela ted products. ISO I ‘l 127 consists of the following Parts, under the general title Prep- aration o f steel substra tes be fore applica tion of paints and related products - Test methods for non-metallic blast-cleaning abrasives: - Part 1: Sampling - Part 2: Determination of particle size distribution - Part 3: Determination of apparent density - Part 4: Assessment of hardness by a glass slide fest - Part 5: Determination of moisture - Part 6: Determination of water-soluble con taminants by conductivity measurement - Part 9: Determination of water-soluble chlorides - Part %: Determination o f abrasive mechanical properties G ISO 1993 All rights reserved.
