The error limits in DIN EN ISO 8655- 5 are significantly lower. The maximum error for a single measure-
ment can be approximated from the sum of error limits EL = A + 2 × CV (for 10 ml: 50 µl + 2 x 10 µl = 70
µl).

volume) indicated on the instrument at equal temperature
(20 ºC/68 °F) of instrument, ambient environment and dis-
tilled water. Testing takes place according DIN EN ISO 8655-
