This 10 kg calibration weight set is a fundamental tool for maintaining weighing accuracy in industrial and laboratory settings. Engineered to OIML Class M1 standards, it serves as a trusted reference for calibrating platform scales, bench scales, and other instruments where 10 kg capacity verification is required. Adherence to the global OIML R111 recommendation ensures the set meets internationally recognized criteria for mass standards, supporting measurement traceability and quality assurance protocols.

The set’s construction prioritizes long-term stability and precision. Each weight is finished to a polish suitable for classes up to F1 and F2, with a standardized density near 7.95 g/cm³ to reduce air buoyancy corrections during calibration. For laboratories requiring the highest level of documentation, E1 and E2 class weights are available with an Accredited Certificate that provides formal verification of metrological properties, which is often necessary for audits and ISO/IEC 17025 accreditation.
