Attachment 0001 - MIL STD A-A-59136.pdf

This document is a Commercial Item Description (CID) for closed cell foam plank packaging materials, specification A-A-59136, dated 28 October 1997. The standard covers foam cushioning materials used for packaging and protection, including static dissipative and fire retardant grades. It defines four primary classes of foam planks: general purpose polyethylene (Class 1), general purpose polypropylene (Class 2), general purpose plank with procuring activity-specified polymer (Class 3), and special purpose skived sheets and shapes (Class 4). The materials are designed to protect items during handling and shipping across temperatures ranging from -54°C to 70°C, with multiple grades including standard (Grade A), static dissipative (Grade B), fire retardant (Grade C), and combined static dissipative and fire retardant (Grade D). The specification also details five material types (I, III, IV, V) with varying constant compression creep characteristics and nominal densities ranging from 32 kg/M³ to 144 kg/M³, allowing selection based on specific packaging and protection requirements.
