CEN/TC 261/SC 2/WG 3 - Paper and paperboard packaging for primary, transport and distribution packaging

The tolerances of the following dimensions of paper sacks as defined in ISO 6590-1 are specified: ply grammage, length of sack, width of sack, width of gusset, circumference of sack with gussets, width of bottom, width of valve, position of the leading edge of the valve sleeve, print position on sack.

The tolerances of the following dimensions of sacks made from thermoplastic flexible film as defined in ISO 6590-2 are specified: thickness of plies, length of sack, width of sack, width of gusset, circumference of sack with gussets, width of bottom, width of valve, position of the leading edge of the valve sleeve, length of the valve sleeve, print position on sack.

Provides a checklist for the characteristics to be specified when ordering sacks made from thermoplastic flexible films. These ordering specifications cover the decription of the sack and do not deal with quantitative performance requirements. Is primarily intended for application to the types of sacks made from thermoplastic flexible films as specified in ISO 6590-2.

Specifies a method of vertical impact testing, the testing procedure and how the results of tests should be presented. It may be performed either as a single test to investigate the effects of vertical impact or as a part of a sequence of tests designed to measure the ability of a sack to withstand a distribution system that includes a vertical impact hazard. The principle of the method is raising the filled sack above a rigid surface and releasing to strike this surface after a free fall, the atmospheric conditions, the height of the drop and the position of the package being set in advance.
