Reference materials are indispensable when it comes to making the world safer and ensuring the accuracy and reliability of measurement results.

Toys that come into contact with skin, for example, must not contain carcinogenic pollutants. Road surfaces, which are exposed to wind and weather and over which thousands of vehicles roll every day, must have a certain level of grip so that they can be driven on safely. And recycling companies must ensure that there are no harmful substances in the recovered raw materials.

In 1912, the Königliches Materialprüfungsamt zu Berlin, a predecessor institution of BAM, offered a reference material for the first time. At that time, it was a matter of normal steel samples with which the carbon determination could be calibrated. Due to increasing demand and technological progress, the range was rapidly expanded in the following years.

Today BAM offers more than 300 different reference materials which are distributed worldwide. To give you an impression of the versatility and range of the different reference materials produced and offered by BAM, we would like to introduce nine of them in more detail.
