Plastics — Determination of pourability

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.

Plastiques — Détermination de l'aptitude à l'écoulement

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.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-
chemical properties, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 249, Plastics, in accordance with the Agreement on technical cooperation between
ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 6186:1998), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— Clause 2 and Clause 3 have been updated;
— Clause 5 “Apparatus” has been technically revised;
— former Clause 9 "Precision" has been deleted and subsequent clause has been renumbered;
— former Clause 10 "Test report" has been renumbered as the new Clause 9, and has been rearranged
and revised.
Any feedback or questions on this document should be directed to the user’s national standards body. A
