Mesurydd Dwysedd Swmp Dull ISO R60 - Precision Bulk Density Determination

The ISO R60 procedure determines the bulk density of metallic powders under standardized conditions of free fall and gravity packing. It quantifies how a powder occupies volume when poured through a calibrated funnel into a defined container, providing a reproducible measure of packing behavior and flowability.

Offer

• QPI‑BDM1800R60 Bulk Density Meter, designed in accordance with ISO R60 specifications:

  • Funnel assembly: stainless‑steel funnel with a 25 mm orifice a 60° cone angle, precision‑machined for consistent flow.

  • Receiving cup: 25 cm³ cylindrical container, internal diameter and height calibrated to ISO R60 tolerances.

  • Support frame: rigid alignment between funnel and cup, ensuring vertical discharge.

  • Base platform: adjustable leveling feet for horizontal setup.

• Analytical balance: resolution ± 0.01 g.

• Sample handling tools: scoop, spatula, and brush for cleaning between tests.

Principle of Operation

A metallic powder is allowed to flow freely through the funnel into the receiving cup under gravity. The mass of powder filling the known volume is measured, and the ratio of mass to volume gives the dwysedd swmp. The test reflects the powder’s particle size distribution, shape, and surface characteristics.

Test Procedure

1. Instrument Preparation

• Ensure the QPI‑BDM1800R60 is clean, dry, and free of residual powder.

• Level the base using the adjustable feet and a spirit level.

• Confirm that the funnel outlet is centered directly above the receiving cup.

2. Sample Conditioning

• Bring the powder to standard laboratory temperature (typically 23 ± 2 °C).

• Mix gently to homogenize without altering particle size or moisture content.

3. Filling the Funnel

• Close the funnel outlet using the supplied shutter or plate.

• Pour the powder into the funnel until it is nearly full.

• Avoid vibration or compaction during loading.

4. Initiating Flow

• Remove the shutter quickly to allow the powder to discharge freely.

• Do not tap or disturb the apparatus during flow.

• Allow the cup to fill completely until flow stops naturally.

5. Leveling the Cup

• Use a straight edge to strike off excess powder flush with the rim.

• Maintain a smooth motion to avoid compressing the sample.

6. Weighing

• Weigh the filled cup to the nearest 0.01 g.

• Subtract the mass of the empty cup to obtain the net sample mass.

7. Calculation

Report results to three significant figures.

8. Repeatability

• Perform at least three measurements.

• The variation between results should not exceed ± 1 %.

Engineering Notes

• ISO R60 is optimized for metallic powders such as iron, copper, and alloy blends.

• The QPI‑BDM1800R60’s funnel geometry ensures consistent flow and minimizes bridging.

• Cleaning between tests prevents contamination and maintains dimensional accuracy.

• Stainless‑steel construction provides thermal stability and corrosion resistance for long‑term laboratory use.

Interpretation of Results

Bulk density measured by ISO R60 reflects the powder’s packing efficiency under gravity. It is used for:

• Quality control of powder metallurgy feedstocks.

• Comparative evaluation of particle morphology.

• Process calibration for compaction, sintering, and additive manufacturing.

• Verification of supplier specifications for metallic powders.
