3 Series and capacities
3.1 Series of nominal capacity
The series of nominal capacities of wide-necked conical flasks is as follows (given in millilitres):
50 — 100 — 250 — 500 — 1 000
The series of nominal capacities of wide-necked round-bottom flasks is as follows (given in millilitres):
50—100—250—500—1000—2000—4000—6000—10000
The series of nominal capacities of wide-necked flat-bottom flasks is as follows (given in millilitres):
50—100—250—500—1000—2000
3.2 Nominal capacity
The nominal capacity of a flask is the value, selected from the series given in 3.1, which is closest to but not larger than the actual volume to the base of neck.
NOTE The body dimensions recommended in Tables 1 and 2 take this requirement into account.
