Powder Angle of Repose with Glass Funnel QPI-PAR2800 - Application:
Déi QPI‑PAR2800 Powder Angle of Repose Tester is designed for precise measurement of powder flowability using the fixed‑funnel method, a procedure referenced across ASTM and ISO powder‑handling practices. The instrument uses a borosilicate glass funnel, e precision height block, and a calibrated base plate to generate a reproducible conical pile from which the natural angle of repose is calculated.
ASTM‑Aligned Test Method (Fixed Funnel Procedure)
Although ASTM does not have a single dedicated “Angle of Repose” standard, the method is widely used in ASTM powder‑flow characterization practices (e.g., ASTM C1444, ASTM D6393, ASTM E11 sampling guidance). The QPI‑PAR2800 follows the ASTM fixed‑funnel procedure, which is recognized across powder‑handling industries.
ASTM Procedure Overview
Prepare the Test Setup
Position the glass funnel at a fixed height above the stainless steel base plate.
Ensure the funnel orifice is clean, dry, and free of residual powder.
Condition the Powder Sample
Sieve or de‑agglomerate the powder according to ASTM sampling practice.
Confirm moisture content and particle size distribution are stable.
Controlled Powder Discharge
Allow the powder to flow freely through the funnel without vibration or mechanical assistance.
The powder forms a natural conical pile on the base plate.
Measurement of the Cone Geometry
Measure the height (H) of the pile using the integrated height gauge.
Measure the diameter (D) of the pile at its widest point.
Angle Calculation The angle of repose is calculated using the standard geometric relationship as presented in the ASTM Test Standard.
Rapportéieren
Report the angle in degrees.
Include powder conditioning details, funnel height, and environmental conditions.
ASTM Engineering Purpose
The ASTM fixed‑funnel method is used to evaluate:
powder cohesiveness
flowability during handling
hopper discharge behavior
suitability for mixing, blending, tableting, or packaging
It is especially relevant for pharmaceutical powders, food ingredients, pigments, metal powders, and fine chemicals.
ISO‑Aligned Test Method (ISO Powder Flowability Practice)
ISO standards such as ISO 4324, ISO 4490, an ISO 9276‑6 reference powder flow behavior and free‑flow measurement. The QPI‑PAR2800 follows the ISO fixed‑funnel angle‑of‑repose method, which is widely used in European laboratories.
ISO Procedure Overview
- Instrument Preparation
- Mount the glass funnel at the ISO‑specified height (typically 50–75 mm).
- Verify the base plate is level and free of vibration.
- Sample Loading
- Introduce the powder into the funnel without compaction.
- Avoid tapping or shaking to maintain ISO free‑flow conditions.
- Formation of the Powder Cone
- The powder flows through the funnel and forms a symmetrical cone.
- ISO emphasizes visual inspection of flow behavior through the transparent glass funnel.
- Dimensional Measurement
- Measure cone height and diameter using ISO‑calibrated gauges.
- Repeat the test to confirm reproducibility.
- Angle Determination
ISO uses the same geometric formula as the corresponding ASTM Test Standard.
- Documentation
- Record environmental conditions (humidity, temperature).
- Note any flow irregularities such as arching, bridging, or clumping.
ISO Engineering Purpose
The ISO method is preferred when:
- powder purity and visibility are critical
- flow behavior must be visually documented
- the powder is fine, cohesive, or sensitive
- the laboratory requires traceable, repeatable measurement conditions
This makes the glass funnel version ideal for pharma, cosmetics, food powders, additive manufacturing powders, and high‑value chemicals.
