ASTM C1492-22

Standard Specification for Concrete Roof Tile

ABSTRACT
This specification deals with the standards for concrete tiles intended for use as roof covering where durability and appearance are required to provide a weather-resistant surface of specified design. The tiles are manufacture from cement, water, and mineral aggregates and shaped during manufacturing by molding, pressing, or extrustion. The tiles may or may not contain inclusion of other materials. The tiles shall also be tested for the following requirements: dimensional tolerance, freeze thaw, transverse strength, permeability, and water absorption.
SCOPE
1.1 This specification covers concrete tiles intended for the use as roof covering where durability and appearance are required to provide a weather-resistant surface of specified design.  
1.2 Tiles are manufactured from portland cement, water, and mineral aggregates with or without the inclusion of other materials.  
1.3 Tiles are shaped during manufacturing by molding, pressing, or extrusion. The shaping method can be used to describe the tile.  
1.4 Other constituents, such as chemical and mineral admixtures established as suitable for use in concrete, shall conform to ASTM standard specifications where applicable, or shall be shown by tests or experience not to be detrimental to the durability of concrete.  
1.5 Tiles are generally planar or undulating rectangular shapes available in a variety of cross-sectional areas profiles, shapes, sizes, surface textures, and colors.
Note 1: Concrete roof tiles covered by this specification are made from lightweight or normal weight aggregates, or both.
Note 2: When particular features are desired, such as color, surface texture for appearance, or other special features, such properties should be specified by the purchaser. However. the local sellers should be consulted as to the availability of concrete roof tile having a desired feature.  
1.6 The text of this specification references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
