(#Tb Designation: D 2808 - 69 (Reapproved 1990)
Standard Test Method for
Compressive Strength of Corrugated Fiberboard (Short
Column Test)'
This standard is issued under the fixed designation D 2808; 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
supemipt epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers the determination of the
edgewise compressive strength, parallel to the flutes, of
single-wall, double-wall, or triple-wall corrugated fiberboard.
1.2 This standard does not purport to address the sajêty
problems associated with its use. It is the responsibility of the
user of this standard to establish appropriate safety and
health practices and determine the applicabilìly of regulatory
limitations prior to use.
