Scope

This document describes the test method for determining the burning time, flame height, and residual mass percentage of rigid foam plastics. This document is suitable for small-scale tests to evaluate the vertical combustion performance of rigid foam plastics under laboratory conditions. This document is not suitable for materials that melt or drip during the combustion process. This document is not suitable for evaluating the fire hazard of materials under actual fire conditions, and it cannot be used as the sole basis for effectively assessing the fire hazard of materials.
