This specification covers non-asbestos, fiber-cement shingles, shakes, and slates (roofing products) of nominally uniform thickness (non-tapered) and texture, including accessories designed to provide the weather-exposed surfaces on roofs of buildings. Flexural strength; product modulus of rupture; breaking moment; density test; water absorption; moisture content; water tightness; frost resistance; warm water resistance; and heat/rain resistance shall be made to conform to the specified requirements.
1.1 This specification covers fiber-cement shingles, shakes, and slates (roofing products) of nominally uniform thickness (non-tapered) and texture, including accessories designed to provide the weather-exposed surfaces on roofs of buildings.
1.2 This specification is not applicable to non-asbestos fiber-cement roofing shakes, shingles, and slates with designed varying profiles and thicknesses (Specification C1530), particle board (Terminology D1554), or cement-bonded particleboards (Specification BS 5669: Part 4) and (ISO 8335).
1.3 This specification does not include details of product installation or installed system performance. Refer to the manufacturer's installation literature for proper installation instructions, to Specification C1459 for roofing systems performance, and to Test Methods E108 for levels of fire resistance.
1.4 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.
1.5 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.
