Fire Retardant Paint Test Apparatus (Large Plate Method)

What is the Fire Retardant Paint Test Apparatus (Large Plate Method)

The Fire Retardant Paint Test Apparatus (Large Plate Method) is a testing device used to evaluate the fire-resistant properties of fire-retardant paints on larger surfaces. In this method, a paint-coated large plate or panel is exposed to a controlled flame or heat source, allowing for the assessment of the paint’s performance in slowing ignition, limiting flame spread, and reducing heat release over an extended area.
