ASTM 2105 DRIVER

Note 4 — Reinforcements of plastics with glass fiber offer wide opportunities for designing and producing products with markedly different responses to loading even when the basic geometry of the product is similar. The values given in parentheses are provided for information purposes only. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. A number in parentheses indicates the year of last reapproval. A gage length of less than 2. Set the speed of testing, and start the machine. Level Zero and Level One Tests.

In the case of pipe for general field use, internal pressure, as well as loads in tension, compression, torsion, and flexure must be resisted to some degree. Hence, it is recommended that each machine 1205 studied individually and veri? Tighten the grips evenly and?

This instrument shall be free of inertia lag at the speci?

Link to Active This link will always route to the current Active version of the standard. As a result, it is important that the purchaser and the seller both have a clear understanding and agreement on the signi? A gage length of less than 2. Historical Version s - view previous 21055 of standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

For referee tests, the resolution of discrepancies must be resolved between aastm purchaser and the seller. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? The test specimen shall be held in such a way that slippage relative aztm the grips is prevented insofar as possible.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Report the result to three signi? Materials possessing a low order of ductility may not exhibit a yield point.

It is desirable, but not essential, that this instrument automatically record this distance or any change in it as a function of the load on the test specimen or of the elapsed time from the start of the test, or both.

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. NOTE 5—It is recognized that the constant rate-of-crosshead-movement type of test leaves much to be desired from a theoretical standpoint, that wide differences may exist between gage marks on the specimen, and that the testing speeds speci?

Note 1 — For the purposes of this standard, polymer does not include natural polymer. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

NOTE 3—It is realized that sstm method of preparation of a material is one of the many variables that affect the results obtained in testing a material.

The accuracy of the testing machine shall be veri? Note 3 — It is realized that the method of preparation of a material is one of the many variables that affect the results obtained 205 testing a material. As a result, it is important that the purchaser and the seller both have a clear understanding and agreement on the significance of this aastm method relative to the intended use.

With this arrangement, the long axis of the test specimen will coincide with the direction of the applied pull through the center line of the grip assembly. Stress-strain data at several levels of temperature, humidity, time, or other variables may be needed to furnish reasonably accurate indications of the behavior of the material. The values given in parentheses are provided for information purposes only.

ASTM D2105 - 01(2014)

Note 4 — Reinforcements of plastics with glass fiber offer wide opportunities for designing and producing products with markedly different responses to loading even when 210 basic geometry of the product is similar.

Express the result as a dimensionless ratio per second units per second and report it to three signi? Different pipe producers have chosen, by design, to offer products having different balances of resistance to such stressing conditions. Record the load carried atsm the specimen when the strain reaches 0.

ASTM D e1. Materials evolved during these weight losses are then analyzed using infrared spectroscopy to determine chemical identity. Originally approved in Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
