IATA PACKING INSTRUCTION 650
This instruction applies to UN3373 on passenger and cargo aircraft and CAO.
General Requirements
The packagings must be of good quality, strong enough to withstand the shocks and loadings normally encountered during transport, including trans-shipment between transport units and warehouses as well as any removal from a pallet or overpack for subsequent manual or mechanical handling. Packagings must be constructed and closed so as to prevent any loss of contents that might be caused under normal conditions of transport, by vibration, or by changes in temperature, humidity or pressure.
The packaging must consist of three components:
(a) a primary receptacle(s);
(b) a secondary packaging (s);
(c) a rigid outer packaging.
Primary receptacles must be packed in secondary packagings in such a way that, under normal conditions of transport, they cannot break, be punctured or leak their contents into the secondary packaging. Secondary packagings must be secured in outer with suitable cushioning material. Any leakage of the contents must not compromise the integrity of the cushioning material or of the outer packaging.
Packages must be prepared as follows:
(a) For liquid substances:
• The primary receptacle(s) must be leakproof and must not contain more than 1 L;
• The secondary packaging must be leakproof;
• If multiple fragile primary receptacles are placed in a single secondary packaging, they must be either individually wrapped or separated to prevent contact between them;• Absorbent material must be placed between the primary receptacle and the secondary packaging. The absorbent material, such as cotton wool, must be in sufficient quantity to absorb the entire contents of the primary receptacle(s) so that any release of the liquid substance will not compromise the integrity of the cushioning material or of the outer packaging.
• The primary receptacle or the secondary packaging must be capable of withstanding, without leakage, any internal pressure of 95 kPa in the range of -40ºC to 55ºC (-40ºF to 130ºF)
