ASTM Certified Balance Calibration Weights

ASTM Certified Balance Calibration Weights

BALANCE CALIBRATION WEIGHTS

CERTIFIED TO ASTM STANDARDS

Class “1” weights for calibrating analytical balances.

Note: Class “S” has been discontinued.

Class “1” has a higher accuracy than Class “S” had.

Each weight is provided with an individual serial-numbered case.

Each weight is supplied with a “Statement of Accuracy”, which certifies that the weight conforms to ASTM class 1 standards (refer to certificate pictured below). The certificate references a serial number that is located on the case (not on the weight itself). Note that the users’ name is not on the certificate.
