Glass inner receptacles (such as ampoules or capsules) intended only for use in sterilization devices, when containing less than 30 mL of ethylene oxide per inner packaging with not more than 300 mL per outer packaging, may be transported in accordance with the provisions in 3;5, irrespective of the indication of "forbidden" in columns 10 to 13 of Table 3-1, provided that:

a) after filling, each glass inner receptacle has been determined to
 be leak-tight by placing the glass inner receptacle in a hot water
 bath at a temperature, and for a period of time, sufficient to
 ensure that an internal pressure equal to the vapour pressure of ethylene oxide at 55 °C is achieved. Any glass inner receptacle
 showing evidence of leakage, distortion or other defect under this
 test must not be transported under the terms of this special
 provision;

b) in addition to the packaging required by 3;5.2, each glass inner
 receptacle is placed in a sealed plastic bag compatible with
 ethylene oxide and capable of containing the contents in the event
 of breakage or leakage of the glass inner receptacle; and

c) each glass inner receptacle is protected by a means of preventing
 puncture of the plastic bag (e.g. sleeves or cushioning) in the
 event of damage to the packaging (e.g. by crushing).
