ASTM D1790 is the standard test method for brittleness temperature of plastic sheeting by impact. It provides a practical way to assess how plastic sheeting behaves when exposed to low temperatures and struck under defined test conditions. This matters because brittleness can affect handling, performance, and service life in applications where flexible sheet materials may be exposed to cold environments. ASTM D1790 helps support more consistent product evaluation and quality control.

What is ASTM D1790?

ASTM D1790 is an ASTM standard focused on measuring the brittleness temperature of plastic sheeting by impact. In practical terms, it describes a test method used to determine the temperature at which a sheet material may become prone to brittle failure under impact conditions. This makes the standard useful for comparing materials, checking cold-temperature behavior, and supporting technical specifications. ASTM D1790 is most relevant when low-temperature performance is an important product characteristic.

Where is ASTM D1790 used?

This standard is commonly used in testing and quality assurance settings where plastic sheeting must be evaluated for low-temperature toughness. It may be applied by manufacturers, laboratories, and purchasers reviewing sheet materials for product selection or acceptance. ASTM D1790 is especially useful when a project involves sheet goods that could encounter impact loading in cooler conditions. It supports consistent testing practices for material development, incoming inspection, and performance verification.

Why is ASTM D1790 important?

ASTM D1790 helps create a consistent basis for measuring brittleness temperature, which is valuable for compliance, procurement, and product comparison. By using a recognized test method, organizations can reduce uncertainty when evaluating whether plastic sheeting is suitable for its intended environment. The standard also supports quality control by making results more repeatable and easier to compare across materials or suppliers. For cold-weather performance assessment, ASTM D1790 is a practical technical reference.
