ASTM D5663-15(2020)

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.
Designation: D5663 − 15 (Reapproved 2020)
Standard Guide for
Validating Recycled Content in Packaging Paper and
Paperboard
This standard is issued under the fixed designation D5663; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
