International Standards Ash Determination (Ash Residue):
DIN EN ISO 1172 - DIN EN ISO 3451-1 (Procedure A) - ISO 247-1 - ISO 1172 - ISO 3451 - VDA 675-130 - a.o.
Ash determination (ash residue) on plastics and elastomers is an analytical method for quantifying the inorganic fillers and reinforcing materials in these materials.
The sample is burned in a muffle furnace or microwave muffle furnace at temperatures of 500°C - 950°C, whereby organic components are oxidized and vaporized, while inorganic substances remain as ash. After cooling, the ash mass is weighed and calculated as a percentage of the original sample mass.
The determined value provides information on the content of inorganic additives and can be used for quality control and material analysis.
This type of analysis is used in particular for glass fiber reinforced materials, to determine the glass content.
Glass fiber-reinforced plastics are widely used in many fields, including the automotive, aerospace and construction industries, and are gaining even more importance due to the dynamic development in the field of electromobility.
The determination of the glass content is an important parameter to estimate the quality and strength of the material.
