About This Item
ASTM D2936 is the ASTM standard that addresses the direct tensile strength of intact rock core specimens. It is used to help determine how rock core behaves when pulled apart, which can be important for engineering assessment and materials evaluation. By focusing on a direct tensile test method, this standard supports more consistent laboratory measurement of rock strength and helps users compare results with greater confidence.
Purpose of ASTM D2936
The purpose of ASTM D2936 is to provide a standardized test method for measuring the direct tensile strength of intact rock core specimens. This helps establish a common approach for laboratory testing where tensile performance of rock material needs to be evaluated. As an ASTM standard, it supports repeatable test practices and clearer communication of results across engineering, testing, and quality-related workflows. The standard is especially useful when a direct tensile property is needed for technical decision-making.
Common use cases of ASTM D2936
ASTM D2936 is commonly used in rock mechanics and geotechnical laboratory settings where intact rock core specimens are tested for direct tensile strength. It may be applied during site investigations, material characterization, and engineering studies involving rock samples from drilling or core recovery. The method is also relevant in workflows that support design evaluation, comparison of rock materials, and documentation of laboratory test results for technical review.
Why ASTM D2936 matters
This standard matters because tensile strength data for rock can influence engineering judgment, test consistency, and risk reduction in project planning. ASTM D2936 helps create a clear testing framework so results are more suitable for comparison, reporting, and compliance-oriented use. For organizations buying or referencing standards, it provides a defined technical document that can support quality control, procurement specifications, and more reliable evaluation of intact rock core performance.
