ASTM C1704/C1704M-09
(Test Method)Standard Test Method for Sampling and Testing Structural Cementitious Panels
Standard Test Method for Sampling and Testing Structural Cementitious Panels
SCOPE
1.1 These test methods cover sampling and testing of structural cementitious panels. Structural cementitious panels are non-combustible, water durable, fiber reinforced inorganic composite panels intended for use as structural panels when fastened to supports spaced in accordance with the span rating in inches.
1.2 These test methods are utilized in evaluating products cited in Specification C 1705/C 1705M.
1.3 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.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
