This British Standard describes methods for the determination of those properties of sheet or block cushioning materials particularly relevant for package design purposes; dynamic cushioning performance, creep strain and residual compression set.
The standard also includes methods for the determination of relevant properties of loose fill materials and for the measurement of fungal growth of both cushioning and loose fill materials.
NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
