Stainless steel standard test and calibration weights are precision-engineered artifacts, leveraging the superior corrosion resistance, non-magnetic nature,

density, and stability of austenitic stainless steel (316L/304). Manufactured to exacting international standards (OIML R111, ASTM E617) within strict tolerances

for specific accuracy classes, and accompanied by traceable calibration certificates, they are the fundamental tools for ensuring the accuracy and reliability of

weighing instruments across science and industry. Proper handling and storage are paramount to preserve their integrity.
