National instrument test procedures

Test procedures, including national instrument test procedures (NITP), describe the step-by-step process for verifying measuring instruments and inspecting pre-packaged products.

General information for test procedures

This general information for test procedures contains terminology and general information to accompany the test procedures.

Sampling and test procedures for prepackaged products

Trade measurement inspectors use the sampling and test procedures for prepackaged products to inspect the markings and actual contents of prepackaged products.

National instrument test procedures (NITPs)

NITPs are used to assess whether measuring instruments:

The number of the NITP generally refers to the classes or subclasses of servicing licences.

NITP 0: general national instrument test procedures

Use NITP 0 where a test procedure for a particular measuring instrument has not been determined.

NITP 1: length measuring instruments

NITP 2: area measuring instruments

NITP 3.1: trade masses of 1 mg to 20 kg

NITP 4.2: beverage dispensers

NITP 4.3: alcoholic beverage measures

NITP 4.4: lubricating oil measures

NITP 4.5: graduated measures

NITP 5.1: fuel dispensers other than LPG dispensers

NITP 5.2: bulk flowmetering systems for liquid hydrocarbons other than LPG

NITP 6.1 to 6.4: non-automatic weighing instruments

NITP 6.5: continuous totalising automatic weighing instruments (belt weighers)

NITP 6.6: automatic rail weighbridges

NITP 6.7: automatic packaging conveyer weighers

NITP 6.8: wheeled loaders
