An absolute frequency measurement of a CO/sub 2//OsO/sub 4/ secondary frequency standard, operating in the mid-infrared, is reported. A brief description of the measurement chain linking this standard to a hydrogen maser evidences the critical points. The measured frequency stability shows that the measurement system reaches the flicker floor of the frequency standard, below the 10/sup -14/ level.
