I'm assuming you're referring to the Australian Standard AS 2331.3.1, which is a part of a series of standards for methods of testing plastics.
The AS 2331.3.1 standard is available for purchase from Standards Australia, either in print or digital format. You can also access a preview or purchase a PDF copy of the standard from their website. as 2331.3.1 pdf
Here's a comprehensive feature on the topic: I'm assuming you're referring to the Australian Standard
The AS 2331.3.1 standard is specifically designed for determining the density of non-rigid plastics, including thermoplastics, thermosets, and elastomers. The method involves measuring the density of a plastic specimen by immersing it in a density gradient column, which is a column filled with a mixture of two liquids of different densities.

In conclusion, AS 2331.3.1 is an important standard for determining the density of plastics using the density gradient column technique. The standard provides a reliable method for quality control, material selection, and research and development. You can purchase a copy of the standard from Standards Australia or access equivalent standards from international organizations.
