Interior Cushioning. Containers shall protect the item from shock or vibration to the degree specified by the component manufacturer. Delicate materials as described in [Chapter 2], during drop testing from a drop height of 1 meter measured from the bottom of the container to the floor or drop surface, must not have a deflection of less than 60% into the cushioning material, and the unit must not be capable of 'bottoming out' at that drop height. For the purpose of this specification, all materials and devices used internally in reusable shipping containers for the purpose of absorbing shock are considered to be cushioning materials. Materials shall possess the following properties: Resilient Non-Dust Producing Mold Resistant Durable All cushioning material shall be permanently attached to the container sides. Additional void fill material such as plastic bubble wrap or foam sheets may be added to restrict movement of an item within its container as long as the material is reusable and does not reduce the cushioning characteristics of the container. It is acceptable to have dunnage material which is adjustable and interchangeable. Adjustable materials, while fixed to the containers, are capable of adjustment to receive varying sizes of units. Interchangeable materials may be switched between parts and / or containers. Containers using the "dunnage board" principle fall into this type. Shock absorbing devices such as shock mounts, air cylinders, or xxxxxxxx, etc., shall be suitable for use when designed to provide the protection required. Miscellaneous wadding such as newspaper or rags, and loose fill packing materials such as plastic 'chips' or 'peanuts' shall not be used as dunnage or cushioning material. Foam-in-Place (FIP) dunnage is not acceptable for use in Category I containers. 7-2-5. Lids Lids shall be designed to prevent warping. Where hinged lids are used, they shall be equipped with appropriate limit devices (lid stays). Where unhinged lids are used, lid limiting devices presenting potential damage to the packaged unit or container closure mechanism shall be sleeved or positioned to protect against this possibility. Lids will not be nailed or glued to the container sides. 7-2-6. Closure Fasteners and Hardware All hardware, including fasteners used to secure a lid closed, shall be recessed, flush or guarded so that no protrusions could cause damage to the container or to other goods shipped in the same conveyance. The design should avoid the need for special opening ...
