Large packagings of fibreboard shall be conditioned for at least 24 hours in an atmosphere having a
controlled temperature and relative humidity (r.h.). There are three options, one of which shall be
chosen.
The preferred atmosphere is 23 °C ± 2 °C and 50% ± 2% r.h. The two other options are: 20 °C ± 2 °C
and 65% ± 2% r.h.; or 27 °C ± 2 °C and 65% ± 2% r.h.
NOTE: Average values shall fall within these limits. Short term fluctuations and measurement
limitations may cause individual measurements to vary by up to ± 5% relative humidity without
significant impairment of test reproducibility.

Test requirements

Bottom lift test

Applicability

For all types of large packagings which are fitted with means of lifting from the base, as a design type
test.

Preparation of large packaging for test

 
The large packaging shall be loaded to 1.25 times its maximum permissible gross mass, the load being
evenly distributed.

Method of testing

The large packaging shall be raised and lowered twice by a lift truck with the forks centrally
positioned and spaced at three quarters of the dimension of the side of entry (unless the points of entry
are fixed). The forks shall penetrate to three quarters of the direction of entry. The test shall be
repeated from each possible direction of entry.

Criteria for passing the test

No permanent deformation which renders the large packaging unsafe for carriage and no loss of
contents.

Top lift test

Applicability

For types of large packagings which are intended to be lifted from the top and fitted with means of
lifting, as a design type test.

Preparation of large packaging for test

The large packaging shall be loaded to twice its maximum permissible gross mass. A flexible large
packaging shall be loaded to six times its maximum permissible gross mass, the load being evenly
distributed.

Method of testing

The large packaging shall be lifted in the manner for which it is designed until clear of the floor and
maintained in that position for a period of five minutes.

Criteria for passing the test

 
(a) Metal and rigid plastics large packagings: no permanent deformation which renders the large
packaging, including the base pallet, if any, unsafe for carriage and no loss of contents;
(b) Flexible large packagings: no damage to the large packaging or its lifting devices which
renders the large packaging unsafe for carriage or handling and no loss of contents.

Stacking test

Applicability

For all types of large packagings which are designed to be stacked on each other, as a design type test.

Preparation of large packaging for test

The large packaging shall be filled to its maximum permissible gross mass.
