Programme Overview

Programme scope of application

IANZ accreditation in the field of Chemical Testing is generally granted to testing laboratories conducting tests of a chemical nature. Laboratories conducting chemical testing may also be accredited under other industry specific IANZ laboratory accreditation programmes. Examples are:

* Ministry for Primary Industries (MPI) Recognised Laboratory Programme

* Drinking-Water Testing Programme

A Fee Schedule can be found under the Forms section on this page.

Scopes of Accreditation

The scope of accreditation of an accredited chemical testing laboratory is, in general, classified according to the type(s) of samples tested (the Class of Test), then further defined by the specific tests conducted (the analyte) and the test method or technique used.

Commonly accredited Classes of Tests include:

* Metals and alloys

* Ores and minerals

* Cement and concrete

* Petroleum products and fuels

* Paints and surface coatings

* Leather and textiles

* Timber, pulp and paper

* Foods

* Drugs and pharmaceuticals

* Agricultural samples (soils, plants, fertilisers)

* Waters

* Gases

* Environmental samples

* Biological specimens

* Asbestos

A full list of the current Classes of Test is included in the IANZ publication Specific Criteria for Accreditation – Chemical Testing. Laboratories seeking IANZ accreditation under the Chemical Testing programme should not consider this list exhaustive, nor feel constrained by it. This Class of Test structure used by IANZ is an arbitrary classification system used for convenience and can be added to as the situation demands.

Note: The allocation of accredited tests into specific fields of testing can also be somewhat arbitrary in nature. While general principles are followed, there will always be exceptions to these principles. Laboratories seeking accreditation, or persons seeking out accredited laboratories for specific tests should not restrict themselves to only those in the Chemical Testing laboratory accreditation programme. For example, chemical tests can normally be classified into the areas of organic, inorganic or physical chemistry. However, some laboratories in the Chemical Testing programme will be accredited for purely physical or functional testing of sample properties, particularly in the areas of food testing and petroleum related products, or for tests that are biochemical in nature, e.g. ELISA, diagnostic biochemistry and related testing. Biochemical tests may also appear in the accreditation scope of Biological Testing laboratories.
