Plastics - Determination of pourability (ISO 6186:2023)

This document specifies two methods, A and B, for determining the pourability of plastics in powdered and granular form, by measuring the flow time through a funnel under specified conditions.
From method A, information concerning the processability can be derived, whilst method B is especially designed for process control during manufacture.
The methods specified are not necessarily applicable to all plastics in powdered and granular form.

Kunststoffe - Bestimmung der Rieselfähigkeit (ISO 6186:2023)

Dieses Dokument legt zwei Verfahren, A und B, für die Bestimmung der Rieselfähigkeit von Kunststoffen in Form von Pulver und Granulat durch Messung der Durchflusszeit durch einen Trichter unter festgelegten Bedingungen fest.
Aus dem Verfahren A können Informationen bezüglich der Verarbeitbarkeit abgeleitet werden, während Verfahren B speziell für die Prozesskontrolle während der Herstellung ausgelegt ist.
Die festgelegten Verfahren sind nicht unbedingt für alle Kunststoffe in Pulver  oder Granulatform anwendbar.

Plastiques - Détermination de l'aptitude à l'écoulement (ISO 6186:2023)

Le présent document spécifie deux méthodes (méthode A et méthode B) pour la détermination de l’aptitude à l’écoulement des plastiques en poudre et en granulés, par mesurage du temps d’écoulement à travers un entonnoir dans des conditions spécifiées.
La méthode A permet d’obtenir des informations concernant l’aptitude à la mise en œuvre, alors que la méthode B est spécifiquement destinée au contrôle des procédés en cours de production.
Les méthodes spécifiées ne s’appliquent pas nécessairement à la totalité des plastiques en poudre et en granulés.

Polimerni materiali - Določanje časa pretoka prahov in granulatov (ISO 6186:2023)

Ta dokument določa dve metodi, in sicer metodo A in B, za določanje časa pretoka polimernih materialov v obliki prahu in granulatov z meritvami časa pretoka skozi lijak pod določenimi pogoji.
Z metodo A je mogoče pridobiti podatke o primernosti za obdelavo, metoda B pa je posebno zasnovana za nadzor procesov med proizvodnjo.
Opisani metodi ne veljata nujno za vse polimerne materiale v obliki prahu ali granulatov.

Foreword
ISO (the International 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. Each 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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
