A03 Drawing 36-3-145.pdf

This is a vendor item drawing specification document for an expanded plastic packaging resin product. The document specifies materials, quality requirements, and performance standards for a 70/30 polystyrene/polyethylene crosslinked foam material with a "gray-green" color designation.

The material must meet specific performance criteria including long-term compressive creep less than 0.5% at 1 PSI static load over 1000 hours, compressive strength of 26.4±1.2 PSI at 10% deformation and 31.4±1.3 PSI at 25% deformation, puncture resistance of 14.9±1.0 ft-lbs (with 0.75 inch plunger), and water absorption less than 0.5% by volume. All testing must be conducted using ASTM standards including D3575, D3763, and C272. The foam density must be 2.0 PCF, with specific tolerances outlined in the specifications. The suggested source of supply is listed as Nova Chemicals Inc., located at 400 Frankfort Rd, Monaca, PA 15061-2298. The document includes revision control information with dates ranging from 07/07/93 to 07/07/20, indicating this is an actively maintained specification. The drawing number is 56-5-145 with Sheet 1 identified, and the document is designated for U.S. Army Expeditionary Warrior Experimentation Center and Natick Soldier Center in Aberdeen Proving Ground, Maryland.
