This standard does not address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. D685 Practice for Conditioning Paper and Paper Products for Testing. Discontinued D1968 Terminology Relating to Paper and Paper Products E122 Practice for Choice of Sample Size to Estimate a Measure of Quality for a Lot or Process Significance and Use Tensile properties measured in this test method are fundamental properties associated with the manufacture, or end use, or both, of paper and paper products. They may be influenced by, or indicative of the type fibers used or the treatment of the fibers, or both, in a particular paper.
Tensile strength is indicative of the serviceability of many papers.
Stretch and sometimes-tensile stiffness are indicative of the ability of the paper to conform to a desired contour. Tensile energy absorption is a measure of the ability of a paper to absorb energy at the strain rate of the test, and indicates durability of papers. Tensile stiffness often gives a better indication of the mechanical response of the sheet to converting forces than do tensile rupture criteria. The tensile testing machine must be capable of providing the measurement data required for making the calculations specified. Must be equipped with a load measuring device and a recorder which must be capable of accurate calibration.
