A commercially available cushioned, fiberboard pack was evaluated for both its electrostatic protection properties as well as its shock and vibration characteristics with regard to the critical protection of sensitive electronic components. The cushioning performance of the pack was compared with that of a similar size standard Type II Fast Pack PPP-B-1672. The results of this evaluation indicated that the pack provided cushioning protection which, on average, was comparable to that obtained with the standard Type II Fast Pack. Using as a reference base, the static charge built up on a standard Type II Fast Pack, which contains no antistatic treated materials, it was determined that the pack having electrostatic protection properties avoided the development of electrostatic fields which measured as high as 4.5 KV in the standard pack. Other concepts are also currently being considered for providing electrostatic protection for the Type II Fast Pack. These include the use of conductive carbon impregnated polyurethane foams as well as foams treated with antistatic materials.
