Reference materials-ISO/REMCO's work provides economic and social benefits

摘要

For example, they are needed to detect critical amounts of dangerous compounds in our food, to diagnose whether our bodies are functioning correctly for a healthy life, and to check whether a batch of steel is strong enough for the safe construction of a bridge.Such measurements can only be performed when the corresponding measurement instruments have been properly calibrated. This is the same procedure as used when the accuracy of a set of weighing scales is checked by using a known standard weight. Consequently, materials which can be used for instrument calibration - such as the kilogram standard - are required. These are known as "reference materials".
