These ASTM Class 6 calibration weight sets provide convenient reference masses for routine checks of laboratory scales and balances. Durable stainless-steel weights are organized in a protective case to help minimize handling damage, contamination and loss. Each set includes a traceable certificate to support documented verification and quality-system records. Multiple mass combinations allow laboratories to select the reference range appropriate to their instruments and testing workload.
Key Features
- The sets are manufactured to ASTM E617 Class 6 tolerances, providing a defined reference-weight classification for suitable laboratory verification work.
- A traceable certificate helps laboratories document reference mass values and maintain equipment-check records.
- Protective storage cases help keep weights organized, clean and ready for repeated use.
- Stainless-steel construction supports durability in laboratories where weights are handled frequently.
- Multiple set configurations let laboratories select a mass range that fits their scales rather than purchase unrelated individual weights.
Included Items
Selected calibration weight set, protective case and traceable certificate.
Lab Manager's Tip
Handle weights with clean gloves or appropriate tools and store them in their case after use. ASTM E617 defines weight classes, but the calibration-weight class must also be suitable for the balance readability and the mass-accuracy requirements of the specific ASTM/AASHTO test being performed.
Typical Applications
Balance checks, scale verification, laboratory quality assurance, construction materials testing, documented weighing-system checks and calibration support.
