Artikel 6

1. The coffin must be impervious; the inside must contain absorbent material. If the competent authority of the State of departure consider it necessary the coffin must be provided with a purifying device to balance the internal and external pressures. It may consist of:
(i) either an outer coffin in wood with sides at least 20 mm thick and an inner coffin of zinc carefully soldered or of any other material which is self-destroying;
(ii) or a single coffin in wood with sides at least 30 mm thick lined with a sheet of zinc or of any other material which is self-destroying.
2. If the cause of death is a contagious disease, the body itself shall be wrapped in a shroud impregnated with an antiseptic solution.
3. Without prejudice to the provisions of paragraphs 1 and 2 or this Article the coffin, if it is to be transferred by air, shall be provided with a purifying device or, failing this, present such guarantees of resistance as are recognised to be adequate by the competent authority of the State of departure.
