ASTM Individual Scale Calibration Weights

ASTM Class 5 and 6 sets offer high accuracy with tight tolerances and uncertainties of less than 1/4 of the tolerance. Weight surfaces meet or exceed ASTM tolerance and design restrictions. Scale calibration weight sets are manufactured from durable stainless steel and are provided in a rugged protective case to ensure weights are held securely, kept clean, and dust free. Available with certificate options traceable to NIST, including ISO/IEC 17025 accredited certification or traceable certification to aid in meeting SOP and regulatory requirements.

Applications

Used to test commercial weighing devices by weights & measures officials and service technicians. NIST F weights may be used to test most accuracy Class III scales and Class IIIL or IIII scales. Appropriate for weighing applications such as force measuring.

Construction

Two-piece

Design Features

Cast iron scale calibration weights ≤50kg, ≤100lb, are grip handle and ≥100kg, ≥200lb, are block design for lifting with hook.
