Definitions
Public pool is defined in NZS 5826:2010 as the pool or pools, their fixtures and
surrounds, shower and changing areas, fun equipment, play areas, and attached
facilities where they exist.
Cuboid, for the purpose of this unit standard, refers to the shape of the volume of
water contained within a rectangular pool.
Standard International units refer to metric units of measurement for length, mass,
time, temperature, electric current, luminous intensity and amount of substance.

Controls for microorganisms that affect pool water quality are identified in terms of
their use and impact on water quality.
chemical controls – pH scale, alkalinity, chlorine disinfection;
mechanical controls include but are not limited to – filters, ultra violet
light.
Range
1.3
Tests for microbiological organisms are identified in terms of type, significance,
testing frequency, and compliance with NZS 5826:2010.
