There are basically 2 tests are performed on river sand
Sieve analysis - No matter from where you get the river sand - no sand will meet the requirement stated in IS code for plastering purpose. For concrete it may meet the requirement.

Silt Content - its too high compare with standards in most of the sources.

River sand should not be used for any kind of work.

For Crush Sand or manufactured sand following tests are performed.
Sieve Analysis - Results are compare with Zone of sand which is Zone 1 to 4.
Water absorption - there is no specification for it but low absorption will give you better result.
Specific Gravity - use to check yield of concrete or mortar - no specification for it in any code.
Visual Inspection - Should be free from murrum and other sedimentary rocks, clay etc.
