ASTM D1505 Density of Plastics by the Density Gradient Technique

ASTM D1505 is a standard test method used to determine the density of plastics by the density-gradient technique. The test method is used to measure the density of various plastic materials, which is an important parameter for quality control and material specification purposes.

Introduction to ASTM D1505

ASTM D1505 is a widely used test method for measuring the density of solid plastic materials using the density-gradient technique. The density of plastic material is the mass per unit volume and is expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). The results obtained through the ASTM D1505 test method are specially used for quality control, reliability check, performance evaluation, and specification purposes. The accuracy of the ASTM D1505 test is better than 0.05 % when the gradient tube is designed carefully per the dimensions mentioned in this test method. ASTM D1505 test is based on observing the level to which a specimen sinks in a liquid column exhibiting a density gradient compared to standards of known density.

ASTM D1505 Test Method

The test procedure for ASTM D1505 can be broken down into two main steps: preparing the density gradient column and testing the plastic sample.

Preparing the Density Gradient ColumnThe density gradient column is prepared by layering a series of liquids with known densities. The column can be prepared using a variety of liquids, including water, ethanol, toluene, and other solvents. The liquids are carefully layered in the column to form a gradient of densities, with the densest liquid at the bottom and the lightest liquid at the top. Once the gradient is formed, the column is allowed to settle for a period of time to ensure that the liquids are stable and do not mix.
Testing the Plastic SampleThe plastic sample is dissolved in a solvent and poured into the density gradient column. The sample moves through the column and settles at the point where its density matches the density of the liquid in the column. The density of the plastic material is then determined by measuring the height of the sample in the column and the density of the liquid at that point.

ASTM D1505 Specimens

Specimen detailsASTM D1505 is generally applicable to most plastics, but the specific sample size and shape can vary depending on the type of plastic being tested.
Specimen dimensionsSpecimen size and shape for ASTM D1505 vary depending on the specific test requirements.
Specimen preparationSpecimens are injection molded or cut from molded or extruded sheets or plates. The specimen must be free of voids and other defects that could affect the test results.

ASTM D1505 Results

The results of the test method are used to determine the density of the plastic material. The density is reported in units of grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). The results can be used for quality control, material specification, and research purposes. Mechanical and physical properties are also determined such as hardness, ductility, and lamination factor. 

Tests related to ASTM D1505 

ASTM D1505 is similar to several other standards that measure the density of plastics, including ASTM D792 and ISO 1183. ASTM D792 is a test method for the density and specific gravity of plastics by displacement, while ISO 1183 is a test method for the determination of the density of non-cellular plastics. These standards are used to measure the density of plastic materials and are important parameters for quality control and material specification purposes.
