Comprehensive Methodologies

The BS EN ISO 1183-1:2025 standard meticulously outlines three primary methods for determining the density of non-cellular plastics:

1. Immersion Method

This method involves immersing the plastic sample in a liquid of known density. By measuring the buoyant force acting on the sample, the density can be calculated with high accuracy. This technique is particularly useful for samples that are irregularly shaped or have complex geometries.

2. Liquid Pycnometer Method

The liquid pycnometer method is a precise technique that uses a pycnometer, a specialized glass container, to measure the volume of the plastic sample. By comparing the weight of the pycnometer filled with a liquid to the weight of the pycnometer with the sample, the density can be determined. This method is ideal for small samples and provides highly reliable results.

3. Titration Method

The titration method involves a chemical reaction to determine the density of the plastic. This approach is particularly effective for plastics that may react with certain liquids or require a more controlled environment for accurate measurement. The titration method is a sophisticated technique that offers precise results for specific types of plastics.

BS EN ISO 1183-1:2025

This standard BS EN ISO 1183-1:2025 Plastics. Methods for determining the density of non-cellular plastics is classified in these ICS categories:

• 83.080.01 Plastics in general

This document specifies three methods for the determination of the density of non-cellular plastics in the form of void-free moulded or extruded objects, as well as powders, flakes and granules. —     Method A: Immersion method, for solid plastics (except for powders) in void-free form. —     Method B: Liquid pycnometer method, for particles, powders, flakes, granules or small pieces of finished parts. —     Method C: Titration method, for plastics in any void-free form. NOTE            Density is frequently used to follow variations in physical structure or composition of plastic materials. Density can also be useful in assessing the uniformity of samples or specimens. Often, the density of plastic materials depend upon the choice of specimen preparation method. When this is the case, precise details of the specimen preparation method are intended to be included in the appropriate material specification. This note is applicable to all three methods. Annex C provides further information for calculating the volume of the specimen used for the determination of the density in the case that method A (the immersion method) is applied.
