Water of natural resources (ICS 13.060.10)
Water quality — Irrigation water — Tolerance limits (15 page(s), in English)
The standard specifies essentially a user needs of the quality of water required for different irrigation uses. It is intended to provide the information to make judgements on the fitness of water to be used for irrigation purposes, primarily for crop production. The standard is applicable to any water that is used for irrigation purposes, irrespective of its source (municipal supply, borehole, river, etc.) or whether or not it has been treated.
