SZNS ISO 5667-5:2006 Water quality – Sampling – Part 5: Guidance on sampling drinking water from treatment works and piped distribution systems

E225.24

  1. Scope

This part of ISO 5667 establishes principles to be applied to the techniques of sampling water intended for human consumption.

For the purposes of this part of ISO 5667, water intended for human consumption comprises :

a). All water either in its original state or after treatment, intended for drinking, cooking , food preparation, or other domestic purposes, regardless of its origin, plus

b) All water used in any production undertaking for the manufacture, processing, preservation or marketing of products or substances intended for human consumption unless the competent national authorities are satisfied that the quality of the water cannot affect the wholesomeness of the foodstuff in its finished form.

This part of ISO 5667 is also applicable to sampling situations that can arise to the investigation of system defects or emergency situations where the safety of sampling operatives is not compromised

This part of ISO 5667 does not provide guidance for water sources or for products generated by using drinking water. The following items are examples of cases not addressed by the present document :

  • the sampling of source water, for example groundwater and surface water impoundments
  • sampling of drinking water supplies derived from non- continuous sources ( for example, from road tankers )
  • sampling of bulk water on airplanes, trains and ships
  • the sampling of beverage products ( including bottled water ) or food containing potable water used in itys preparation
  • sampling of drink vending machines that dispense unsealed cups of drinks
