Key Differences
≠The primary and most critical difference is the reinforcing material. IS 13000:1990 specifies asbestos fibers, whereas all current international equivalents (e.g., EN 12467, ISO 8336) explicitly prohibit the use of asbestos and are designed for alternative fibers like cellulose or synthetic polymers (PVA).
≠Modern standards like EN 12467 use a detailed performance-based classification system (e.g., Categories A, B, C, D) based on strength and durability for specific applications (interior, exterior semi-exposed, exterior exposed). IS 13000 has a simpler classification based on thickness and physical properties.
≠Current international standards include more rigorous durability tests, such as freeze-thaw and heat-rain cycle tests, especially for exterior-grade sheets, which are not specified in IS 13000:1990.
≠Test methods for bending strength, while conceptually similar, differ in specifics. EN 12467 requires determining a 'characteristic' strength value, which is a statistical measure, while IS 13000 specifies a minimum 'average' strength.
Key Similarities
≈The basic matrix composition is similar, utilizing a hydraulic binder (Portland cement) and fine siliceous aggregate as primary components, to which reinforcing fibers are added.
≈All standards cover the same product form: rigid, flat sheets intended for use in building construction for applications like partitions, ceilings, siding, and backer boards.
≈The fundamental performance tests are conceptually alike, focusing on key properties such as bending strength (Modulus of Rupture), water absorption, and apparent density to ensure product quality.
≈Dimensional and geometric requirements are specified in all standards, including tolerances for length, width, thickness, and squareness, to ensure interchangeability and proper installation.
