With the exception of composite packagings having a plastics receptacle with outer steel drum, plastics packaging shall be tested for permeability. A suitable test method can be found in ADR and RID. This test is only required when the packagings described above are intended to transport benzene, toluene, xylene or mixtures and preparations containing these substances.
NOTE Some substances can lead to permeation of the product through the (plastics) wall of the packaging In some cases these substances give such a high degree of swelling that the required performance of the packaging is not met. In other cases the performance criteria are met, but the high degree of permeation could lead, besides the loss of product, to a dangerous situation because of vapours with dangerous explosive or toxic concentrations. Barrier materials or surface modifications can be used to decrease the amount of permeation and thus the risk of a dangerous situation.
Packagings and IBC’s shall be selected and prepared for testing as specified in ISO 16495:2013, Clause 5 Concerning closure applications all tests for a particular liquid shall be carried out at the same torque.
NOTE 1 The closure torque can vary for different seals.
NOTE 2 If application of the specified closure torque affects the subsequent performance of the seal during the packaging testing then the specified closure torque can be applied after the conditioning period.
NOTE 3 When mechanical tests have been successfully performed, the stacking test can be waived for standard liquids on composite packagings with plastic inner receptacles and non-plastics outer packaging.
NOTE 4 When mechanical tests, in accordance with ISO 16495:2013 have been successfully carried out, it is not necessary to carry out bottom lift test, top lift test and vibration test, for all IBC types. The stacking is also not necessary for composite IBCs having a non-plastics outer structure that supports the stacking load.
The packagings/IBCs user (with the assistance, where appropriate, of the packagings/IBCs manufacturer and the test laboratory) shall identify the packaged substance. The assimilation process shall consist of identifying the plastics material concerned and its possible interactions, such as swelling, environmental stress cracking (ESC) and molecular degradation.
The specification forms for plastics packagings/IBCs should identify the material by polymer type and grade.
NOTE Where tests are carried out using the packaged substance, the test report can be applicable for other substances having equivalent or lesser chemical effects.ISO 13274 pdf download.
