General information on measurement uncertainty
This explains the importance of understanding the quality and reliability of laboratory test results. As no measurement is perfectly exact, measurement uncertainty quantifies the level of confidence in a result and its fitness for purpose. IANZ-accredited laboratories are required to evaluate and report this uncertainty, ensuring results are meaningful and internationally recognised. This document is prepared by International Accreditation New Zealand (IANZ), a crown entity established under the Testing Laboratory Registration Act 1972.

Ice-point & measurement uncertainty papers
Provides practical guidance on performing ice-point checks, understanding measurement uncertainty, and interpreting the importance of calibration traceability. This includes The Ice Point Explained, which demonstrates how the melting point of water can be used as a simple, effective, and low-cost temperature reference. Prepared by the Measurement Standards Laboratory of New Zealand (MSL), New Zealand’s national metrology institute, this resource supports best practice in temperature verification and measurement accuracy.
