Описание (английский):

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.

Overview

EN ISO 13517:2020 - "Metallic powders - Determination of flow rate by means of a calibrated funnel (Gustavsson flowmeter)" specifies a standardized laboratory method to measure the flow rate (flowability) of metallic powders using a calibrated funnel (Gustavsson flowmeter). The test measures the time for 50 g of powder to flow through a standardized orifice and applies to freely flowing metallic powders, including powders for hardmetals and mixes containing organic additives (e.g., lubricants).

Key Topics and Requirements

Test principle: measure elapsed time for 50 g of powder to pass through the calibrated funnel orifice (reported as seconds per 50 g).

Apparatus: calibrated funnel (specified dimensions), non-magnetic corrosion‑resistant construction, rigid stand with vibration‑free base, balance (accuracy ±0.05 g), timing device (accuracy ±0.1 s), and reference grit for calibration.

Calibration:

Manufacturer calibration: five repeat determinations on reference grit; average stamped on funnel and must be within 40.0 s ± 0.5 s for 50 g.
User calibration: verify reference grit flow and apply a correction factor (40.0 divided by measured flow) when necessary. Discontinue funnel use if reference flow decreases below 37 s.

Sampling and test portions: typical test portion 50.0 g ± 0.1 g (alternative 90–110 g for automation); at least three determinations per sample; sample mass for testing ≥ 200 g.

Procedure: fill funnel, start timing when orifice opened, stop when last powder exits; light tap permitted once to initiate flow. Powders that do not flow are considered non‑flowable by this method.

Results: arithmetic mean of three runs, reported in seconds per 50 g; apply correction factor if applicable.

Limitations: applicable only to powders that flow freely through the specified orifice.

Applications and Users

Quality control and acceptance testing of metallic powders, including:

Powder metallurgy (PM) manufacturers and suppliers
Producers of hardmetal powders and powder blends with lubricants
R&D laboratories developing powder feedstock
Additive manufacturing (metal AM) and metal injection molding (MIM) quality teams evaluating powder flowability

Use cases: incoming inspection, process control, material specification verification, comparative benchmarking of powder batches, and traceable lab reporting.

Related Standards (if applicable)

EN ISO 13517:2020 is part of the suite of powder metallurgy standards developed by ISO/TC 119 and CEN. Users should consult other ISO/CEN standards on sampling, apparent density, and powder characterization for comprehensive powder testing programs.

Keywords: EN ISO 13517:2020, Gustavsson flowmeter, calibrated funnel, metallic powders, flow rate, flowability, powder metallurgy, powder testing, calibration.
