IS 13008:1990 is the Indian Standard (BIS) for shallow corrugated asbestos cement sheets. This standard specifies the requirements for shallow corrugated asbestos cement sheets used for roofing and cladding. It covers the material composition, dimensions and tolerances, physical requirements such as breaking load and water absorption, and methods of testing. This document aims to ensure quality and performance for these specific roofing products.
! This standard has been WITHDRAWN by BIS. It should not be used for new construction or manufacturing.
! The product contains asbestos, a hazardous material. Extreme care and appropriate safety measures (PPE, wet methods) are required when handling, cutting or demolishing existing sheets to prevent inhalation of carcinogenic fibres.
! Modern, safer alternatives include non-asbestos fibre cement sheets (IS 14862) or metal roofing sheets.

Key Differences
≠Material Composition: IS 13008 permits chrysotile asbestos fibres, whereas modern international standards like EN 494 and ASTM C1530 explicitly ban asbestos and specify alternative reinforcements like PVA or cellulose fibres.
≠Product Classification: EN 494 classifies sheets into categories (e.g., A, B, C) based on their bending moment capacity, allowing for a range of strengths. IS 13008 provides a single minimum breaking load requirement.
≠Test for Frost Resistance: Modern European standards (EN 494) include mandatory tests for frost resistance or freeze-thaw cycling for products intended for use in colder climates, a requirement not specified in IS 13008:1990.
≠Health & Safety Markings: Current international standards for fibre-cement often mandate markings like 'NT' (New Technology) to clearly indicate the absence of asbestos, a practice not required by the 1990 Indian standard.
Key Similarities
≈Product Geometry: All standards cover shallow corrugated profile sheets, defining key dimensions like pitch, depth, and overall width to ensure compatibility and proper installation for roofing and cladding.
≈Bending Strength Test: The fundamental test for mechanical strength in both IS 13008 and its international counterparts is a three-point bending test, where a sheet is supported and a load is applied to determine its breaking strength.
≈Water Performance Requirements: Core performance criteria such as water absorption and impermeability are specified in all standards to ensure the sheets function effectively as a weather barrier.
≈Dimensional Tolerances: All standards specify permissible tolerances on length, width, thickness, and profile dimensions to control manufacturing quality and ensure product consistency.
