IS 13286 : 2025 Surface Spread of Flame for Thermal Insulation Materials - Methods of Test
1 SCOPE
1.1 This standard prescribes the methods of test for determining surface spread of flame for thermal insulation materials.
1.2 Two methods of tests have been prescribed for determining the tendency of thermal insulation materials to support the spread of flame across their surface, namely, a large-scale test for exposed surfaces of walls and ceilings and a small scale surface spread of flame test suitable for preliminary testing for development and quality control purposes.
NOTE - There is no direct correlation between these two tests.
