About This Item
ASTM D1586/D1586M is the ASTM standard for the Standard Penetration Test (SPT) and split-barrel sampling of soils. It provides a recognized method for obtaining in-situ soil test results and representative samples that support geotechnical evaluation, site characterization, and engineering decisions. As a widely used reference for field testing, it helps promote consistency in test execution and reporting, which is important when comparing results across projects, locations, or contractors.
What is ASTM D1586/D1586M?
This standard is the technical document that defines the Standard Penetration Test and split-barrel sampling procedure for soils. ASTM D1586/D1586M is used to describe how the test and sampling method are performed so results can be interpreted with greater consistency. The official standard title shows that it addresses both penetration testing and soil sampling, making it relevant where field data and recovered samples are both needed for geotechnical assessment and engineering review.
Where is ASTM D1586/D1586M used?
ASTM D1586/D1586M is commonly used in geotechnical fieldwork for soil investigation, subsurface exploration, and foundation-related testing. It is especially relevant when a project needs both an SPT result and a split-barrel soil sample from the same test location. The standard is typically applied in boring programs and related field testing workflows where soil conditions must be evaluated in a repeatable, documented way for design, analysis, or construction support.
Why is ASTM D1586/D1586M important?
This standard matters because it supports consistent field testing and sampling practices that are often relied on in engineering and procurement workflows. Using ASTM D1586/D1586M can help reduce ambiguity in how soil test results are obtained and reported, which improves comparability and technical confidence. For project teams, it also supports quality control, compliance with established testing expectations, and better risk management when evaluating subsurface conditions.
