1 Scope
1.1 This standard (Part 13) covers the methods for determination of shear strength of soil with a maximum particle size of 4.75 mm in undrained, consolidated undrained and consolidated drained conditions.
Note - The undrained test can be performed only for highly impermeable clays. When silty clays and silts are involved, partial drainage is inevitable. This fact should be recognized while interpreting the results.
