This part of ISO 835 specifies requirements for an internationally acceptable series of graduated pipettes with comparatively large jets, for which a waiting time of 15 s is specified in order to compensate for the possible effect of shorter delivery times, and which are adequate for general laboratory purposes. They are adjusted to class A accuracy.
The details specified are in conformity with ISO 384 and ISO 835/1.
NOTE — Particular requirements for graduated pipettes, for which no waiting time is required, are specified in ISO 835/2, and for blow-out pipettes in ISO 835/4.
