ISO 23145-1:2007 specifies a procedure to determine the tap density of granulated or ungranulated ceramic powders by a constant-volume measuring method.
Abstract
Overview
EN ISO 23145-1:2016 (ISO 23145-1:2007) defines a standardized method to determine the tap density of granulated or ungranulated ceramic powders. Commonly used in fine ceramics and advanced technical ceramics industries, the standard uses a constant-volume measuring method: a known-volume container is filled, tapped under controlled conditions until packing saturation, and the mass per unit volume (tap density) is calculated. Keywords: tap density, bulk density, ceramic powders, ISO 23145-1, EN ISO 23145-1:2016.
Key topics and technical requirements
- Scope & principle: Tap density is measured by allowing powder to fall freely into a fixed-volume cylinder, tapping to achieve saturated packing, and calculating mass/volume.
- Apparatus:
- Cylindrical stainless-steel container, volume 100 cm3 (diameter-to-height ratio ≈ 1). Example dimensions: 50 mm diameter × 51 mm height and a 50 mm ring.
- Sieve per ISO 565 (aperture 0.71 mm) for sample preparation.
- Balance with precision 0.1 g (0.01 g recommended for very fluffy powders).
- Tapping apparatus with stroke (10 ± 1) mm and tapping frequency
