2、the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods cover sampling and testing ofstructural cementitious panels.Structural cementitious panelsar
3、e non-combustible,water durable,fiber reinforced inorganiccomposite panels intended for use as structural panels whenfastened to supports spaced in accordance with the span ratingin inches.1.2 These test methods are utilized in evaluating productscited in Specification C1705/C1705M.1.3 The values st
4、ated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This
5、 standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1
