Applies to adhesives intended for the bonding of unit loads, primarily fibreboard containers, both corrugated and solid fibre, the surfaces of which have not been coated, waxed or otherwise treated, but which may be either printed or unprinted. An indication of critical bonding parameters for the palletizing operation and general notes on adhesive application are given in an appendix. Test methods are included.

This specification sets out requirements for adhesives which are used for the bonding of unit loads.The specification is applicable to adhesives which are primarily intended for fibreboard containers, both corrugated and solid fibre, the surfaces of which have not been coated, waxed, or otherwise treated, but which may be either printed or unprinted.NOTES:1. If the adhesives are used for bonding either fibreboard containers which have been treated or containers made from other materials, modification of the requirements may be necessary.2. The purchaser should provide adequate information to the supplier on the nature of the adherends and desirable techniques. Some criteria for selecting the adhesives, and the bonding procedure are given in Appendix
