Why annealing loss is important for materials analysis
Annealing loss is used to determine how much organic material is present in a sample. This is an important indicator of the quality and applicability of sandy materials, for example.
A too high content of organic material can affect the performance and durability of the material. Therefore, understanding this composition is essential for reliable applications.
At Normec, we perform this test according to RAW 2015 test 28, so you can count on standardized and reliable results.
How we accurately determine annealing loss and CaCO₃ content
During analysis, we measure how much mass a dry sample loses when heated. This provides insight into the organic matter content.
The test consists of the following steps:
-
1.
Weighing the dry material
-
2.
Heating to 500 °C to determine the organic material
-
3.
Weighing the sample again
-
4.
Heating to 900 °C to determine CaCO₃ content
These controlled steps give you an accurate picture of the composition of the material.

Frequently Asked Questions
-
Loss of annealing is the mass lost by a material when it is heated. This loss is used to determine the organic matter content.
-
At 500 °C, the organic matter is burned. At 900 °C, the CaCO₃ content is determined because it decomposes at a higher temperature.
-
The test is mainly applied to sandy materials.
-
The analysis is performed according to RAW 2015 test 28.
