What are the standard capacities of cylindrical measures specified in IS 10079?

The standard nominal capacities are 30, 15, 10, 3, and 1 litre (Table 1).

What is the primary use of this equipment?

It is used for determining the bulk density (unit weight) and percentage of voids in aggregates, a key property for concrete mix design.

What is the allowable tolerance on the capacity of these measures?

The actual capacity of the measure shall not vary from its nominal capacity by more than ±1.0 percent (Clause 2.1).

What material is used to make these measures?

The measures are made from metal, typically steel sheet, which is rigid and protected against corrosion (Clause 3.1).

This standard specifies the material, dimensions, and construction requirements for cylindrical metal measures. These measures are used in laboratories for determining the unit weight (bulk density) and voids of both fine and coarse aggregates, as well as fresh concrete.

Practical Notes

These measures are fundamental for conducting the unit weight test on aggregates as per IS 2386 (Part 3).

Ensure the inner surface is smooth and free of dents before use, as deformities can affect the volume and lead to inaccurate results.

The 30-litre measure filled with aggregate can be very heavy; ensure handles are secure and use proper lifting techniques.
