increase in length from the start of the force-extension curve toa point corresponding with the breaking force, or otherspecified force, as shown on the autographic record. Calculatethe apparent elongation as the percentage increase in lengthbased on the gage length (initial nominal testing length of thespecimen). 12.2.1 For each testing situation, calculate the average apparent elongation at the breaking force or other specified force, of acceptable specimens. NOTE 14-The elongation calculated as a percentage of the gage length for the specimen should be referred to as the apparent elongation because the actual length of fabric between the jaws is usually greater than the initial (gage) length. This difference in length is frequently due to fabric pull-out from between the jaws. Thus, elongation, calculated on the gage length, has an error which is dependent upon the amount of pull-out.13. Report 13.1 State that the specimens were tested as directed in TestMethod D5035. Describe the material or product sampled and the method of sampling used. 13.2 Report the following information for each laboratory sample: 13.2.1 The average breaking force of acceptable specimens for each test condition and strip test. 13.2.2 The average percent apparent elongation of acceptable specimens for each test condition and strip test, if calculated. Identify this elongation as apparent elongation at breaking force or apparent elongation at specified force, as required by the test specifications. 13.2.3 Number of specimens tested in each direction. 13.2.4 Type of strip test and testing machine used. 13.2.5 Maximum force obtainable in the range used for testing. 13.2.6 Pretension used, if any. 13.2.7 Size ofjaw faces used. 13.2.8 Type of padding used in jaws, modification of specimen gripped in the jaws, or modification of jaw faces, if any. 13.2.9 Number of yarns in the width of the strip, if less than 20. 13.2.10 Average time required to break, if applicable, for allspecimens giving acceptable breaks. 13.2.11 Whether conditioned or wet testing, or both. 13.2.12 In the case of tests on wet specimens, state whetherallowance was made for shrinkage. 13.2.13 Whether sizing or finishes have been removed and,if so, by what procedure.14.
