ASTM has released an update to ASTM D6817. The latest version is now ASTM D6817-15.
There was an important change with the latest version of ASTM D6817. The values for compressive resistance at 5% and 10% were moved from the main body of the document to the Appendix. This is important since the content of the Appendix is non mandatory. Thus, the compressive resistance for geofoam at 5% and 10% are no longer requirements of the standard. This means that when geofoam is tested for compliance with ASTM D6817-15 the compressive resistance at 5% and 10% is not necessary unless specified by a customer.
