IS 1195:2002 is the Indian Standard (BIS) for bitumen-mastic for flooring. This standard specifies the requirements, composition, and application methods for bitumen mastic used as a jointless flooring material. Engineers use this code to specify heavy-duty, damp-proof, and dust-free flooring in industrial, commercial, and residential buildings.

Key Differences
≠IS 1195 defines two specific grades for flooring (Grade 1 General, Grade 2 Light Duty), whereas EN standards provide a framework for specifying properties based on end-use (e.g., traffic, climate) rather than fixed grades.
≠The 'Hardness Number' test in IS 1195 (at 25°C) has different parameters (load, indenter size, duration) from the 'Indentation' test in EN 12697-20 (often at 40°C), making direct numerical comparison of hardness values difficult.
≠IS 1195 includes a specific 'Acid-Resisting Grade' with a defined test method. European standards like EN 13108-6 do not include this by default; chemical resistance is treated as a special property to be specified by the user.
≠IS 1195 has a narrower scope, focusing exclusively on flooring. The equivalent EN standards (e.g., EN 13108-6, EN 12970) cover a broader range of applications, including road pavements and waterproofing.
Key Similarities
≈All standards describe a hot-applied, voidless material composed of bitumen binder and a fine mineral aggregate with a high proportion of filler (passing 0.075 mm sieve).
≈The primary performance characteristic in both IS 1195 ('Hardness') and the EN standards ('Indentation') is the material's resistance to penetration, which is critical for flooring applications.
≈The fundamental composition, requiring a limestone-based aggregate and filler, is a common feature across the Indian and European standards for achieving the desired mastic properties.
≈The manufacturing and application concept is identical: heating the pre-mixed material in a specialised cooker/transporter and laying it hot by hand-floating to form a seamless surface.
