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.
