I gcás baisc-sceithte, meánluachanna thar fhad an scaoilte a thógtar mar shamplaí comhiomlána sreabh-chomhréireacha, nó spotsampla a thógtar roimh an sceitheadh ar choinníoll gur meascadh an t-eisilteach ar bhealach iomchuí agus go bhfuil sé aonchineálach.
In the case of batch discharge, average values over the release duration taken as flow-proportional composite samples, or, provided that the effluent is appropriately mixed and homogeneous, a spot sample taken before discharge.
