The soil or material being tested using this test method should not have coarse material in excess of 1½ inch in diameter, should not have natural voids that allow sand to enter, should have sufficient cohesion to maintain stable sides during excavation, and should not have organic or highly plastic characteristics that deform during testing. Which of these is correct?
Understand the Problem
The question is asking for the conditions or characteristics that the soil or material being tested must meet according to a specific test method, indicating that it should not have coarse material, large voids, poor cohesion, or certain deformable qualities.
Answer
ASTM D1556.
The correct test method is ASTM D1556, which applies to soils without coarse material exceeding 1½ inch in diameter, no natural voids for sand to enter, sufficient cohesion for stable excavation sides, and without organic or highly plastic deformation characteristics.

More Information
ASTM D1556 is a standard used to determine the density and unit weight of soil in place by the sand cone method. This method is suitable for certain soil conditions specified in the guidelines.
