Relating
ETHAFOAM* Brand Polyethylene Foam Products to Federal Commercial Item
Descriptions
In late 1997, the long-standing Federal Specification for polyethylene foam for
packaging, PPP-C-1752 was canceled, and two Commercial Item Descriptions (CIDs)
were issued to take its place.
Although there is some similarity between the CIDs and the Federal Specification
they replace, the CIDs require compliance with fewer property limits, and
generally have less stringent test requirements. Many government users are
finding the replacement CIDs to be insufficient for their needs, so we
anticipate The Dow Chemical Company will continue to receive inquiries relative
to PPP-C-1752 compliance for some time. In general, the ETHAFOAM products, which
were certified to meet PPP-C-1752 requirements, also meet the CID requirements.
Where test data to certify to this fact is available, the product certification
documents have been edited to reflect compliance with both PPP-C-1752 and the
appropriate CID.
The tables below give a quick reference to which ETHAFOAM brand products fit
into which classification under both the new CIDs and the former Federal
Specification. Further information regarding each CID is given following the
tables.
