Error Limits - BRAND Dispensette TA Operating Manual

Error limits

Error limits according DIN EN ISO 8655-5 related to the nominal capacity (=
maximum volume) indicated on the instrument, obtained when instrument and
distilled water are equilibrated at ambient temperature (20 °C/68 °F). Testing
takes place according DIN EN ISO 8655-6 with a completely filled instrument
and with uniform and smooth dispensing.

Note:
The error limits are well within the limits of DIN EN ISO 8655-5. The maximum error limit for a single
measurement can be calculated EL = A + 2 CV (e.g. for volume 10 ml: 50 µl + 2 x 10 µl = 70 µl).
