Using ASTM precision calibration weights and mass reference standards helps ensure accuracy in laboratory weighing processes. Rice Lake offers ASTM calibration weights in Class 0, 1, 2, 3 and 4 as individual weights, sets and complete kits.

ASTM precision laboratory metric calibration kits are used when calibrating Class I and II balances, ASTM Class 4, 5 and 6 weights, student laboratory use, rough weighing operations, tolerance testing and verification checks.

ASTM precision laboratory metric individual weights are used when calibrating Class I and II balances, ASTM Class 4, 5 and 6 weights, student laboratory use, rough weighing operations, tolerance testing and verification checks.
