Designed to meet ASTM E617-23 specifications for Class 1 tolerances.
Constructed from polished stainless steel for durability and corrosion resistance.
Nominal value marked on weights for clear identification.
Supplied as a complete set for calibrating a 500 mg capacity.
Serial numbers applied to the set's protective case for traceability.
Density of 7.95 g/cm³ conforms to standard reference conditions.
The Rice Lake 500 mg Calibration Weight Set is engineered as a fundamental tool for metrology professionals and laboratory technicians who demand the highest level of mass accuracy. Each weight in the set is meticulously manufactured from stainless steel and finished with a polished surface to minimize dust accumulation and ensure long-term stability. This adherence to strict material and manufacturing standards is what grants the set its ASTM Class 1 designation, making it suitable for calibrating high-precision Class I and Class II analytical and micro balances.
Primary applications for this precision weight set include the routine tolerance testing and verification of balances used in research, pharmaceutical development, and stringent quality assurance protocols. It serves as an ideal reference for checking ASTM Class 4, 5, and 6 weights, performing verification checks, and is robust enough for student laboratory use and rough weighing operations where a trusted standard is required. The weights are marked with their nominal value, while the set's serialization on the case provides the necessary documentation for audit trails and quality management systems, such as ISO 17025.
