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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
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
www .iso .org/ iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 119, Powder metallurgy, Subcommittee
SC 2, Sampling and testing methods for powders (including powders for hardmetals), in collaboration
with the European Committee for Standardization (CEN) Technical Committee CEN/SS M11, Powder
metallurgy, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).
This second edition cancels and replaces the first edition (ISO 13517:2013), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— tolerance for the funnel angle has been added;
— reference grit has been used instead of Chinese emery grit;
— the mandatory Clauses 2 and 3 (Normative references and Terms and definitions) have been added
and the subsequent clauses have been renumbered.
Any feedback or questions on this document should be directed to the user’s national standards body. A

of a calibrated funnel (Gustavsson flowmeter)
1 Scope
This document specifies a method for determining the flow rate of metallic powders, including powders
for hardmetals and mixes of metallic powders and organic additives such as lubricants, by means of a
calibrated funnel (Gustavsson flowmeter).
The method is applicable only to powders which flow freely through the specified test orifice.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
No terms and definitions are listed in this document.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

4 Principle
Measurement of the time required for 50 g of a metallic powder to flow through the orifice of a calibrated
funnel of standardized dimensions.
5 Apparatus
5.1 Calibrated funnel, with the dimensions shown in Figure 1 (see Clause 6). The dimensions shown
for the flowmeter funnel, including the orifice, are not to be considered controlling factors. Calibration
with reference grit, as specified in Clause 6, determines the working flow rate of the funnel.
The funnel shall be made of a non-magnetic, corrosion-resistant metallic material with sufficient wall
thickness and hardness to withstand distortion and excessive wear.
5.2 Stand and horizontal vibration-free base, to support the funnel rigidly, e.g. as indicated in
Figure 2.
5.3 Balance, of sufficient capacity, capable of weighing the test portion to an accuracy of ± 0,05 g.
5.4 Timing device, capable of measuring the elapsed time to an accuracy of ± 0,1 s.
1)
5.5 Reference grit, a reference powder used for calibration of the funnel .
1) Material complying with 5.5 can be purchased as “Chinese emery grit”. This information is given for the
convenience of users of this document and does not constitute an endorsement by ISO of the company named above.
Equivalent products may be used if they can be shown to lead to the same results.
