Plastic Limit Test Set for Atterberg Limits Testing

The Plastic Limit Test Set is designed to determine the plastic limit of cohesive soils, representing the lowest moisture content at which a soil specimen can be rolled into threads of 3 mm diameter without breaking.

The plastic limit test is an essential part of the Atterberg Limits and provides valuable information for soil classification, engineering properties, and construction suitability. The BESMAK Plastic Limit Test Set is supplied complete with all accessories required for accurate and routine laboratory testing.

Plastic Limit Test Method

The Plastic Limit Test determines the moisture content at which a soil changes from a semi-solid state to a plastic state.

During the test, the prepared soil specimen is rolled into threads with a diameter of 3 mm. The moisture content at which the thread begins to crumble or break is defined as the plastic limit of the soil.

Together with the Liquid Limit Test, this procedure forms one of the two primary Atterberg Limits, which are fundamental for soil classification and geotechnical evaluation.
