Weight Instrument Information
Calibration weights are used to check the reading of scale, to make sure it is still accurate.
- Calibration of scales and balances
ASTM Class 7
Primarily used in industrial applications that require rough measurements, ASTM Class 7 has the highest tolerance allowable in the ASTM classification system. Calibration weights with an ASTM Class 7 are suitable for Class III, Class IIII, and non-designated scales like floor scales, shipping scales, and other industrial devices.
ASTM Classes 4 - 6
ASTM Class 4, ASTM Class 5, and ASTM Class 6 calibration weights are primarily used to check and calibrate Class III, IIIL, and unmarked scales. Precision balances and those scales found in student laboratories typically require calibration weights within these classes. These scales typically have readability, or divisions, lower than 0.1 grams (i.e., 0.5g, 1g, etc.).
ASTM Class 3
Moderate precision balances, or those with readability from 0.1 to 0.01 grams, generally require an ASTM Class 3 calibration weight. These types of scales, like the Ohaus Adventurer AX2202N/E, are commonly found in commercial laboratory environments.
ASTM Class 2
Higher precision balances, or those with readability between 0.01 and 0.001 grams (1 milligram), require an ASTM Class 2 weight for calibration purposes. High precision balances, like the Ohaus Explorer EX423N, are used in the pharmaceutical and chemical compounding industries.
ASTM Class 1
Analytical and semi-micro balances have readabilities of 0.1 mg and 0.01 mg respectively. It is recommended to use an ASTM Class 1 weight when calibrating devices that can weigh out to a fraction of a gram. ASTM Class 1 weights may also be used as references when calibrating other weights with higher tolerances. Users should wear gloves or tweezers when handling these weights as any oils or dirt from their hands can alter the weights' tolerances.
ASTM Class 0 - 000
Almost exclusively, metrology laboratories use ASTM Class 0, ASTM Class 00, and ASTM Class 000 as reference standards for calibrating other weights and are often expensive. Controlled environments are required when using these classes of calibration weights because of their tight tolerances. These classes of weights should be handled delicately with tweezers as they are often minute in size.
