This specification covers non-asbestos fiber-cement roofing shakes, shingles, and slates that are of designed varying profiles and thicknesses manufactured to provide the weather-exposed surfaces on roofs of buildings. These products shall be formed either with or without pressure and cured either under natural or accelerated conditions, to meet the physical requirements of this specification. Breaking load test, water absorption test, frost resistance test, warm water test, accelerated weathering test, water tightness and heat/rain resistance shall be performed to meet the specified requirements.

1.1 This specification covers fiber-cement roofing shakes, shingles, and slates that are of designed varying profiles and thicknesses manufactured to provide the weather-exposed surfaces on roofs of buildings.

1.2 This specification does not include details of product installation or system performance. Refer to the manufacturer's installation literature for proper installation instructions, to Specification C1459 for roofing systems performance, and to Test Method E108 for levels of fire resistance.

1.3 This specification is not applicable to fiber-cement products as specified in Specification C1225.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 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.
