Scope 11 This test method covers the determination of the tensile properties of unreinforced and reinforced plastics in the form of standard dumbbell-shaped test specimens when tested under defined conditions of pretreatment temperature humidity and testing machine speed. The plastics industry is the third largest in the manufacturing sector and accounts for about 450 billion in US GDP.

Compounds in this family are used to create a vast array of consumer goods such as tires footballs and rubber bands. 1-800-328-2255 MTS MTS Criterion and MTS Exceed are registered. Source publication 10 The Application of a Representative Volume Element RVE Model for the Prediction of Rice Husk.

Materials with a thickness greater than 14 mm 055 in shall be reduced by machining. There are over 15000 plants spread out over all 50 states. ASTM D638 - TYPE - I SPECIMEN DIE.

Five types of specimens. While some large multinational. Consult ASTM D638 for more detailed Type I II III IV and V dimensions.

View publication ASTM D638 Type 1 Sample Dimensions. A graphic user interface PC has been incorporated to provide accurate speed control. ASTM D638-01 -Standard Testing Instruments Tensile Testing Machine - Computerized The equipment provides an accurate cross head speed between 50mm and 500mm min.

ASTM D638 is the standard specification for plastics tensile testing. And is powered by a Servo Motor which can be run at variable speed. Definition of the specimens to ASTM D638 The preferred test specimen is the dumbbell Type I which with a thickness of 32 mm 18 inch and a gauge length of 50 mm 2 inches is still relatively similar to common component material thicknesses and at the same time allows for good strain measurement accuracy.

50 200 Distance between grips. 165 mm length 19 mm width 3mm thickness three sample for each sample as. Measure the diameter of rod specimensand theinside and outside diameters of tube specimens to the nearest0025 mm 0001 in at a minimum of two points 90 apartmake these measurements along the groove for specimens soconstructedUse plugs in testing tube specimens as shown inFig.

Many offshored plastics manufacturing operations are returning with the energy and oil revolution. ASTM D638 measures plastics tensile properties including ultimate tensile strength yield strength elongation and Poissons ratio. Elongation measurements with 10 μm absolute accuracy and 05 relative accuracy Specimens for ASTM D638 are dumbbell-shaped with either a 25 mm or 50 mm gauge length.

If you are going to perform this test you. 19 075 Length overall mm. 13 050 Length of narrow section.

115 45 Radius of filet. These shapes are all variants on a dumbbell design with large ends that will be held by the machine while it stretches the piece. ALL reinforced composites including MTS Systems Corporation highly orthotropic laminates shall use Type I specimens.

13 This test method includes the option of determining Poissons ratio at room temperature. Grip section widthstrong 2. 10 mm 004 in in thickness ASTM standard D882 is the preferred test method.

ASTM D638-14 Standard Test Method for Tensile Properties of Plastics 1. The ASTM D638 test method is relatively simple. 165 65 Gauge length.

A universal testing machine tensile testing machine is needed to perform this test. To assess plastic tensile strength you first cut or mold the sample into one of five designated shapes which you choose based on its thickness and rigidity. Width of narrow section.

Astm d638 type i plastic dimensions are in mm a range of typical thickness values is given. 57 225 Width overall mm. Materials with a thickness greater than14 mm 055 in must be reduced by machining13 This test method includes the option of determningPoisson s ratio at room temperatureNOTE I-This test method and ISO 527- 1 are techcally equivalentNOTE 2-This test method is not intended to cover precise physicalprocedures.

This family also produces highly specialized materials such as O-rings on space. This test method uses standard dumbell or dogbone shaped specimens under 14mm of thickness. The samples are cut in the form of a standard dumbbell shape providing the sample a reduced section where the break will occur upon testing.

Type II is used if break does not occur within the parallel section of Type I. Type I is recommended. NOTE 1This standard and ISO 527-1 address the same subject matter.

A 50 mm gauge length is recommended. If your sample is a sheet or film less than 100 mm thick it should be tested to ASTM D882. 22 Jan 2014 0236 PM.

ASTM D638 only applies to rigid plastic samples between 100 mm and 14 mm in thickness. Other thicknesses may be accomodated upon request depending on the application. ASTM D638 is one of the most common plastic strength specifications and covers the tensile properties of unreinforced and reinforced plastics.

All customers need to do is determine which sample type they will be testing. DIMENSIONS TEST DILATOMETER TEST SLIPPERINESS TEST. What are Astm D638 Type 1 Standard Tensile Bar Dimensions.

To ASTM D638-03 the samples were cut up from the manufacturing plate. Non-rigid Plastics The Type III specimen must be used for all materials with a thickness greater than 7 mm 028 in but not more than 14mm 055 in. ASTM D412 is the most common standard for determining the tensile properties of vulcanized thermoset rubber and thermoplastic elastomers.

While it provides similar results to ISO 527-2 ASTM D638 is not considered technically equivalent due to differences in specimen size and test requirements.
