This part of IEC 60695 specifies a small-scale laboratory screening procedure for comparing the relative burning behaviour of vertically or horizontally oriented specimens made from plastic and other non-metallic materials, exposed to a small-flame ignition source of 50 W nominal power.
These test methods determine the linear burning rate and the afterflame/afterglow
The test methods described provide classification systems (see 8.4 and 9.4), which may be used for quality assurance, or the pre-selection of component materials of products.
The methods may be used for the pre-selection of a material, providing positive results are obtained at a thickness equal to the smallest thickness used in the application.
NOTE Test results are influenced by material components, e.g. pigments, fillers and fire-retardants, and properties such as the direction of anisotropy and the molecular mass.
