The tests shall be performed on one of the proposed or similar (similar means: same

materials, same technology, may differ in sizes) molded breakout.

The test reports shall include the name and the address of the laboratory and the results of

the type test. The test reports shall be signed by an authorized officer of the laboratory.

12. PACKAGING &DELIVERY

12.1 The heat shrinkable accessories shall be supplied in a suitable cardboard boxes. The

cardboard should be big enough to contain the sleeves in straight shape. The cardboard box

shall be designed to protect the equipment against ingress of moisture and mechanical damage

during shipment and storage. Components supplied with adhesive coatings shall have means to

prevent the coated surfaces from adhering to each other.

12.2 The cardboard boxes shall be supplied in a seaworthy cardboard or wooden box, shipped

on wooden EURO PALLET 1200x800x150 mm (DIN 15146 T2) appropriate for fork lifting

and durable packed for outdoor storage. The gross weight of each pallet should not exceed

1250 kg.

12.3 The number of items per plastic bag (where relevant), length per reel (where relevant) and

number of items/reels per cardboard box are specified in the table below.

Note: Different arrangement should be agreed with I.E.Co.
