ASTM D2105 PDF

More D Recycled polyethylene film or resin may be used as feedstock, and the film or sheeting may contain additives for surface property improvement, pigments, or stabilizers, or a combination of these, but they must conform to the requirements specified. Material covered in this specification shall be designated by a five-digit type number, with each numeral from 0 to 5 indicating the cell limit within which the values of the density, impact strength, kinetic coefficient of friction, haze, and nominal thickness of the material falls under. The sheet or film shall be manufactured free, as commercially possible, of gels, streaks, pinholes, particles of foreign matter, and undispersed raw material, and without any other visible defects such as holes, tears, or blisters.

More D Materials possessing a low order of ductility may not exhibit a yield point. 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 tests cannot be considered significant for applications differing widely from the load-time scale of the standard test Note 4.

Such applications require more suitable tests, such as impact, creep, and fatigue. Hence, when comparative tests of materials per se are desired, the greatest care must be exercised to ensure that all samples are prepared in exactly the same way; similarly, for referee or comparative tests of any given series of specimens, care must be taken to secure the maximum degree of uniformity in details of preparation, treatment, and handling. For example, a tubular product may be designed to give maximum resistance to torsion loading, but such a product might develop a twist or bow if tested in tension or under internal pressure loading.

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. Different pipe producers have chosen, by design, to offer products having different balances of resistance to such stressing conditions. As a result, it is important that the purchaser and the seller both have a clear understanding and agreement on the significance of this test method relative to the intended use.

Scope 1. Larger sizes may be tested if required apparatus is available. The values given in parentheses are provided for information purposes only. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. The asym cannot be considered significant for applications differing widely from the load-time scale of the standard test Note 4. ASTM D Fiberglass Tensile Test Equipment d Note 3 — It is realized that the method of preparation of a material is one of the many variables that affect the results obtained in testing a material. 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. By means of our fiberglass testing expertise and modular product design, we will help find the testing solution that is right for you. It is the responsibility of the user of this standard to establish appropriate safety and astn practices and determine the applicability of regulatory limitations prior to use.
