Minimum Sample Quantities Required for Tests

Test Name Sample weight (grams)
Bulk Density 800
Hydrometer 50
Moisture Content 1000
Organic Content 120
Microscopy 1000
Permeability 150
Salt Content 100
Sieve Separation 1000
Wax Content 700
Triaxial Test 1200
Tangent Modulus 700

Note:

1) Bulk density, mositure content, triaxial and tangent modulus tests are non-descrtuctive so the samples material can be used in other tests.

2) Typically a single 2500 gram sample that completely fills a gallon zip lock bag is sufficnet material for a full suite of tests.
