IS 10079:1982 is the Indian Standard (BIS) for cylindrical metal measures for use in tests of aggregates and concrete. 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.
Specification for cylindrical metal measures for use in tests of aggregates and concrete
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Nominal Capacities | 0.5, 1, 3, 5, 10, 15, 30 litres | Capacities are determined by maximum aggregate size (e.g., 3L for 25mm, 10L for 37.5mm, 14L for 50mm) | ASTM C29 / C29M-17a |
| Diameter to Height Ratio | Internal diameter shall be approximately equal to the internal height. | Internal diameter shall be between 0.75 and 1.25 of the height. | ASTM C29 / C29M-17a |
| Steel Body Wall Thickness (Minimum) | 3.15 mm | 2.0 mm (for measures ≤ 15L); 3.0 mm (for measures > 15L) | ASTM C29 / C29M-17a |
| Steel Base Thickness (Minimum) | 6.3 mm | 2.0 mm (for measures ≤ 15L); 3.0 mm (for measures > 15L) | ASTM C29 / C29M-17a |
| Top Rim Flatness Tolerance | Implied to be plane and at right angles, no specific tolerance given. | The top rim shall be smooth and plane within 0.25 mm. | ASTM C29 / C29M-17a |
| Handles Requirement | Required for measures of 5 litres and above. | Shall be provided with handles (no specific capacity threshold). | ASTM C29 / C29M-17a |
| Minimum Container for Fresh Concrete Density | Not explicitly defined; same measures are used. | The capacity of the container shall be at least 5 litres. | BS EN 12350-6:2019 |
