NOTE Other terms used in the manufacture of sacks are defined in EN 26590-1 for paper sacks and in EN 26590.2 for sacks made of thermoplastic flexible film. Most of these terms can also be applied to sacks made of jute fabric.
jute sack
a container made of jute fabric, closed at least at one end, possibly in combination with other flexible materials used for the liner, to provide the properties required for filling and the goods distribution chain
NOTE Hereafter where the word “sack” is used in the text of this European Standard, a sack made of jute fabric is to be understood.
3.2
ply
a tissue of jute fabric, forming the walls of a sack

4.2.2 The dimensional tolerances of the sack should be agreed upon between the purchaser and the supplier.
4.2.3 The dimensions and the dimensional tolerances of the sack shall be recorded in the ordering documents.
4.2.4 The description of the dimensions, the method of measuring the dimensions and the dimensional designation of the sack shall be in accordance with
EN 26591-2.
NOTE Though EN 26591-2 is valid for sacks made of thermoplastic flexible film it can he applied to sacks made of jute fabric. However for some forms of sacks made of jute fabric EN 26591.2 cannot be applied. A third part of ISO 6591 will be prepared by ISOI1’C122/SC2, Iackaging— sacks.
