Scope
This part of ISO 5667 establishes principles to be applied to the techniques of sampling water provided for
drinking and for use in the manufacture of food and beverage products.
The guidance given in this part of ISO 5667 is generally confined to those circumstances where water is
drawn from municipal or similar public or private abstraction, treatment or distribution systems for which prior
treatment or quality assessment has resulted in the water being classified as suitable for drinking or potable
process purposes. Specifically, this part of ISO 5667 is applicable to water that is supplied by tanker or other
non-contiguous bulk means, but not contiguously as part of a piped distribution system, during any stage of
use up to and including the point of consumption or transfer to a piped distribution system. This part of
ISO 5667 is also applicable to the distribution and bulk storage of water on aircraft, trucks, trains, ships, and
other vessels and vehicles, as well as to sampling situations that can arise during the investigation of system
defects, initiation of new systems, re-initiation of systems that have been unused for long periods or
emergency situations where the safety of sampling operatives is not compromised.
This part of ISO 5667 does not provide guidance on:
a) the sampling of source water, e.g. groundwater and impoundments;
b) the sampling of potable water supplies derived from contiguous piped supplies covered by ISO 5667-5;
c) the sampling of beverage products (including bottled waters) or food containing potable water used in its
preparation;
d) the sampling of drink vending machines.
