IS 4971:2007 is the Indian Standard (BIS) for recommendations for selection of industrial floor finishes. This standard provides recommendations for selecting appropriate floor finishes for various industrial applications. It classifies performance requirements such as abrasion, impact, and chemical resistance, and guides the selection of a suitable finish based on the intended use and expected loads.

| Parameter | IS Value | International | Source |
|---|---|---|---|
| Traffic Classification | Qualitative: Light, Medium, Heavy, Very Heavy based on vehicle type and load. | Performance-based: 8 flooring types (FeRFA classification) linked to thickness and expected traffic, from foot traffic to heavy forklift traffic. | BS 8204-6:2008+A1:2011 |
| Substrate Moisture Limit (for resin floors) | Not specified quantitatively; base should be 'sufficiently dry'. | Typically ≤75% Relative Humidity (RH) measured with an in-situ probe. Surface-applied DPMs are recommended if higher. | BS 8204-6:2008+A1:2011 |
| Floor Flatness Specification | No quantitative value specified; recommends a 'smooth and level surface'. | Specified using F-Numbers, e.g., 'FF 35 / FL 25' for a random-movement warehouse floor. | ACI 302.1R-15 |
| Abrasion Resistance | Qualitative recommendation, e.g., 'Good abrasion resistance'. No test method specified for selection. | Classified by wear depth using a specified test method (BS 8204-2). Class AR1 (heavy duty) is ≤ 50 µm wear. | BS 8204-6:2008+A1:2011 |
| Chemical Resistance Data | Table with general ratings ('Resistant', 'Attacked') for generic chemical types (acids, alkalis). | Detailed tables rating specific coating systems against specific chemicals, often including concentration and temperature. | ACI 515.1R-01 |
| Heavy-Duty Resin Screed Thickness | General range for 'Polymer Concrete/Mortar' is given as 5 mm to 50 mm. | Specific recommendation for 'Heavy Duty Resin Screed' (FeRFA Type 7) is 'typically applied at 6 mm or more'. | BS 8204-6:2008+A1:2011 |
| Substrate Surface Tensile Strength | Recommends substrate should be 'sound' but does not specify a test or value. | A minimum pull-off strength of >1.5 N/mm² is typically required for resin flooring systems. | BS 8204-6:2008+A1:2011 |
