ASTM D7557/D7557M-09(2021)
(Practice)Standard Practice for Sampling of Expanded Polystyrene Geofoam Specimens
Standard Practice for Sampling of Expanded Polystyrene Geofoam Specimens
SIGNIFICANCE AND USE
5.1 This practice provides guidance on sampling of EPS geofoam in order to determine compliance to Specification D6817/D6817M.
SCOPE
1.1 This practice provides guidance on the location, frequency, and method of sampling representative specimens from large blocks of expanded polystyrene (EPS) geofoam.
1.2 This practice is not intended to replace professional judgment, nor should this guide be applied without consideration of a project’s many unique aspects.
1.3 The word “standard” in the title of this guide means only that this guide has been approved through the ASTM International consensus process.
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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
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.
