Such non-gage section fractures constitute invalid tests. When using active gripping systems, insufficient pressure can lead to slippage, while too much pressure can cause local fracture in the gripping area.
The mounting tabs are gripped or connected to the load train for example, by pin and clevis so that the test specimen is aligned axially along the line of action of the test machine. At the same time, the grip facing material must prevent crushing, scoring or other damage to the test specimen that would lead to inaccurate results.
Either analog chart recorders or digital data acquisition systems may be used for this purpose although a digital record is recommended for ease of later data sstm.
Ideally, an analog chart recorder or plotter shall c1575 used in conjunction with the digital data acquisition system to provide an immediate record of the test as a supplement to the digital record. Means for containing these fragments for later fractographic reconstruction and analysis is highly recommended.
An appropriate solvent can be used afterwards to remove the vacuum grease.
ASTM C – 14 – Standard Test Method for Tensile Strength and Young’s Modulus of Fibers
The total length of the specimen should c15577 sufficiently long at least 1. Handle the test specimen at its ends and avoid touching it in the test gage length. However, other gage lengths can be used as long as they are astn, and in either case, the value of the gage length must be reported.
Center the test specimen over the tab using the printed pattern with one end taped to the tab. Zero the load cell.

Check the axial specimen alignment using whatever methods have been established, as described in 7. Alternatively, the sides of astj tab can be burned using a soldering iron, for example.
Record both the cross-head displacement and force, and strain if applicable. The system compliance is determined as follows: Test specimens with at least three different gage lengths, and perform at least, three tests for each value of the gage length.
Precision and Bias Monte Carlo Simulation X1. The error bars correspond to the largest and smallest values of the errors resulting from repetitions. Radial and axial scales are not the same in c5157 diagrams.
