Pipette calibration (ISO 8655)
Turn weighed water masses into accuracy and precision against the nominal volume.
V = mass × Z
Mass of each dispensed water aliquot.

Pipette calibration (ISO 8655) · V = mass × Z; accuracy = mean − nominal; precision = SD/CV · the lab bench, calculated
ISO 8655✓ V = mass × Z; accuracy = mean − nominal; precision = SD/CV
Mean 100.2 µL, accuracy +0.2%, CV 0.166%

Accuracy is the systematic error (mean minus nominal); precision is the CV. Compare both to your pipette class limits.
ℹ
Z = 1.003 µL/mg at 20 °C. ISO 8655 calls for 10 weighings; you have 10.
