5.1 SIPs are used as roof, wall, and floor components in building structures. The structural performance properties need to be determined for design purposes.

1.1 These test methods cover procedures for determining strength properties under specified loads for rigid-faced structural insulated panels. These test methods are appropriate for structural insulated panels with rigid facings having a minimum thickness of 0.16 in. (4 mm) and an insulating core with a minimum thickness of 1.5 in. (38 mm). These specified loads include:

1.1.1 Transverse loads,

1.1.2 Axial loads,

1.1.3 Shear loads,

1.1.4 Diaphragm loads,

1.1.5 Uplift loads,

1.1.6 Long Term loads

1.1.7 Impact loads, and

1.1.8 Concentrated loads.

1.2 Structural insulated panels are intended to resist structural loads in permanent building structures.

1.3 These test methods are not intended for quality control purposes and do not evaluate the individual components of the structural insulated panels.

1.4 These test methods are not intended to measure dimensional stability.

1.5 The text of this standard references notes and footnotes, excluding tables and figures, which provide explanatory information. These notes and footnotes shall not be considered requirements of the standard.

1.6 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.

1.7 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.

1.8 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.
