PKSC 1020 Lecture Notes - Lecture 9: Ultimate Tensile Strength, Unit Load, Astm International
Document Summary
Secondary contains one or more primary packages. Three basic areas of testing: quality testing, environmental testing, shipping and abuse. Use standard methods and machines to determine quality of materials or combination of materials. Subject to real world or simulated real world conditions. Involves accelerated aging process of elevating conditions to speed testing. Measures effects of environment on product and package and effects of product on the package during storage. Shock and vibration testing (transportation or distribution testing): How package stands up to rigors of shipping, storage and handling. Sophisticated machines used to simulate conditions but they are just simulations. Tappi technical association of the pulp and paper industries. Paper must be conditioned using tappi standards: 24 hrs. @ 73 + 3. 5 of, 50 + 2% rh: creates standard conditions to eliminate variables due to changes in climate or season. Permeability testing: cc/mil/ 100in2/day @ 80of, 90% rh. Mocon method for o2, co2, and wvtr.
