Fire Tests

Fire tests for plastics are essential to ensure safety in a wide range of industries. They are used to understand the specific fire behavior of plastics and identify potential hazards. A not insignificant factor is compliance with regulations, as many industries (e.g. construction, electronics and transportation) are subject to strict fire safety standards. 

Controlling the spread of fire is crucial to minimize the impact of fires, especially in buildings and vehicles. Fire testing also supports quality control by ensuring that plastics meet the required standards and guarantee product integrity. 

In product development, they help to design safe and high-quality products from the outset. In addition, fire testing plays a role in insurance and legal liability issues by enabling companies to prove that their products comply with safety standards. Overall, fire testing is essential to ensure safety, meet standards and minimize risks.
