Plastics - Determination of apparent density of moulding material that cannot be poured from a specified funnel (ISO 61:2023)

This document specifies a method of determining the apparent density, i.e. the mass per unit of volume, of loose material that cannot be poured from a funnel of specified design.
NOTE            For a method of determining the apparent density of loose moulding material that can be poured from a specified funnel, see ISO 60.
This document is applicable to loose moulding materials such as slice, granular or powder.

Dieses Dokument legt ein Verfahren zur Bestimmung der scheinbaren Dichte, d. h. der Masse je Volumeneinheit, von losem Material (Schüttgut), das nicht durch einen Trichter vorgegebener Ausführung abfließen kann, fest.
ANMERKUNG   Zum Verfahren zur Bestimmung der scheinbaren Dichte von losen Formmassen, die durch einen gegebenen Trichter abfließen können, siehe ISO 60.
Dieses Dokument ist anwendbar für lose Formmassen, wie z. B. Mahlgut/Schnitzel, Granulat oder Pulver.

Plastiques - Détermination de la masse volumique apparente des matières à mouler non susceptibles de s'écouler à travers un entonnoir donné (ISO 61:2023)

Le présent document spécifie une méthode de détermination de la masse volumique apparente, c’est-à-dire la masse par unité de volume, des matières à mouler non tassées qui ne sont pas susceptibles de s’écouler à travers un entonnoir d’un modèle déterminé.
NOTE            Pour une méthode de détermination de la masse volumique apparente des matières à mouler non tassées susceptibles de s’écouler à travers un entonnoir donné, voir l’ISO 60.
Le présent document est applicable aux matières à mouler non tassées, par exemple en tranches, en granulés ou en poudre.

Polimerni materiali - Določanje nasipne mase materiala za oblikovanje, ki ga ni mogoče nasuti skozi lij določenih mer (ISO 61:2023)

60 g sipkega materiala za oblikovanje se postopoma in čim bolj enakomerno doda v merilni valj. Bat z določeno maso na merilnem valju se počasi spušča, dokler ga material v celoti ne podpira. Po eni minuti je treba določiti prostornino materiala, ki ga bat stiska, in izračunati nasipno maso.

Overview

EN ISO 61:2023 (ISO 61:2023) specifies a laboratory method for determining the apparent density (mass per unit apparent volume) of loose moulding materials that cannot be poured through a specified funnel. Published by CEN/ISO, this standard applies to loose plastics moulding materials such as slice, granular or powder and updates the earlier edition (supersedes EN ISO 61:1999).

Key topics and technical requirements

  • Scope: Apparent density test for materials that do not flow through the funnel covered by ISO 60 (ISO 60 is referenced for pourable materials).
  • Apparatus:
    • Balance accurate to 0.1 g
    • Ruler accurate to 1 mm
    • Measuring cylinder: smoothly finished, capacity (1000 ± 20) ml, internal diameter (90 ± 2) mm
    • Plunger: hollow cylinder, mass (2300 ± 20) g, diameter slightly less than cylinder internal diameter
  • Procedure:
    • Place (60 ± 0.2) g of material little by little into the measuring cylinder, level the surface.
    • Lower the plunger slowly until fully supported by the material; wait 1 minute and measure material height to nearest 1 mm.
    • Perform three determinations on the sample. Test samples shall not be reused.
  • Calculation and reporting:
    • Apparent density d (g/ml) is calculated by d = m / (A · h), where m = mass (g), A = cross-sectional area (cm²) and h = height (cm).
    • Report the arithmetic mean of three determinations and take two significant digits.
    • Test report must reference ISO 61:2023 and include material ID, individual results and mean, statistical data if required (standard deviation, coefficient of variation or confidence limits), observations and test date.

Applications and users

  • Quality control and incoming inspection of plastic compounds, powders and granules
  • R&D and materials characterization in plastics manufacturing and compounding
  • Test laboratories and certification bodies performing standardized physical tests
  • Process engineers using apparent density to inform feed systems, dosing, and molding process settings
