MIL-HDBK-773A
procedures for the packaging of ESDS items with the specialized preservation code GX
in table J.Ia, and marking requirements via a special marking code, 39, found in table J.X. Unpreserved ESDS items should be handled only at an ESD protective workstation by trained personnel (see Appendix C), who can effectively employ the protective materials and equipment provided. Only antistatic preservation materials will be used to form the unit pack. Preserve and pack ESDS items using the following procedures (see figure 2):
a. Wrap the item in material conforming to MIL-PRF-81705, type II or type III, or cushion the item in material conforming to A-A-3129, type I, grade B, or PPP-C-795, class 2, or A-A-59135, class 1, grade B, or PPP-C-1797, type II, to prevent bag puncture. Reclosable cushioned pouches conforming to MIL-P-81997, type I or II, may be used in lieu of initial wrap or cushioning.
b. Place the wrapped or cushioned item in a bag meeting the criteria specified in
MIL-DTL-117, type I, class F, style 1, made from material conforming to MIL-PRF-
81705, type I, class 1 or 2. The bag should be made of one piece of material folded in half and heat sealed on three sides. This becomes the unit pack holding the ESDS item and can now be handled as you would any non-ESDS item.
c. Place an ESDS device unit pack label (see figure 3) on the unit pack as illustrated in figure 4. In the absence of NSNs, local purchase procedures should be followed when ordering this unit pack sensitive electronic device label. Should this label be temporarily unavailable, unit packs may be marked on two opposing sides with the ESDS device symbol and the statement: "DO NOT OPEN - EXCEPT AT APPROVED FIELD FORCE PROTECTIVE WORKSTATION" or "DO NOT OPEN - EXCEPT AT APPROVED STATIC- FREE WORKSTATION."
d. Most ESDS items (for example, circuit cards, resistors, semiconductors) can utilize 1 of the 12 reusable PPP-B-1672, type II, style D, folding convoluted "fast packs," which are the only fast packs authorized for ESDS items (see figure 4). ESDS items that will not fit into 1 of the 12 authorized fast packs will be packed according to prescribed packaging instructions, or into ASTM D 5118/D 5118M fiberboard containers. Allow for antistatic cushioning, measure for desired size fiberboard container and refer to the recommended fiberboard most frequently used container list (see latest revision of
MIL-STD-2073-1). The listed sizes may be requisitioned through normal supply channels. If box-making equipment is available, containers should be fabricated in accordance with ASTM D 5118/D 5118M. After closure of carton that was accomplished in accordance with ASTM D 1974, apply a sensitive intermediate, or
exterior electronic device caution label on the appropriate container (see figures 3 and 4). Label and mark according to MIL-STD-129.
