            PACKING INSTRUCTION 650 (continued)

            Packages must be prepared as follows:
            (a)  For liquidsubstances:
               •   The primary receptacle(s) must be leakproof and must  not contain more than 1L;
               •   The  secondary packaging must be leak proof;
               •   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,
                   aninternal pressure of 95k Pain the range of -40°C to 55°C (-40°F to 130°F}.
               Note:
               The  capability  of  a  packaging  to  withstand  an  internal  pressure  without  leakage  that  produces  the  specified
               pressure differential should be determined by testing samples of primary receptacles or secondary packagings.
               Pressure differential is the difference between the pressure exerted on the inside of the receptacle or packaging
               and  the  pressure  on  the  outside.The  appropriate  test  method  should  be  selected  based  on  receptacle  or
               packaging  type.  Acceptable  test  methods  include  any  method  that  produces  the  required  pressure  differential
               between the inside and outside of a primary receptacle or a secondary packaging. The test may be conducted
               using  internal  hydraulic or  pneumatic pressure (gauge)  or  external vacuum test  methods. Internal  hydraulic  or
               pneumatic pressure can be applied in most cases as the required pressure differential can be achieved under
               most circumstances. An external vacuum test is not acceptable if the specified pressure differential is not achieved
               and  maintained.  The  external  vacuum      test  is  a  generally  acceptable  method  for  rigid  receptacles  and
               packagings but is not normally acceptable for:
                         flexible receptacles and flexible packagings;
                         receptacles and packagings filled and closed under a absolute atmospheric pressure lower than 95
                          kPa.
                         The outer packaging must not contain more than 4L.This quantity excludes ice, dry ice or liquid
                          nitrogen when used to keep specimens cold.
            (b)  For solid substances:
               •   The primary receptacle(s)must be sift proof and must not exceed the outerpackaging weight limit;
               •   The secondary packaging must be sift proof;
               •   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;       ·
               •   Except for packages containing body parts,organs or wholebodies,the outerpackaging must not contain more
                   than 4kg. This quantity excludesice,dry ice or liquid nitrogen when used to keep specimen scold;
               •   If there is any doubt as to whether or not residual liquid may be present in the primary receptacle during transport
                   then a packaging suitable for liquids, including absorbent materials, must be used.
                -An itemized list of contents must be enclosed between the secondary packaging and the outer packaging.
            At least one surface of the outer packaging must have a minimum dimension of 100 mm x 100 mm (4 in x 4 in).
            The completed  package  must be capable  of successfully passing  the drop  test  described in 6.5.1.1except that  the
            height of the drop must not be less than 1.2 m. Following the appropriate drop sequence, there must be no leakage
            from the primary receptacle(s) which must remain protected by absorbent material,when required,in these secondary
            packaging.
