astm d638 dimensions

For consistency all samples intended for ASTM D638 testing must first be tested for and comply with ASTM D5947 a standard for physical dimensions. OTHER THICKNESSES MAY BE ACCOMODATED UPON REQUEST DEPENDING ON THE APPLICATION.

ASTM D638 Type 1 Sample Dimensions.

. OTHER THICKNESSES MAY BE ACCOMODATED UPON REQUEST DEPENDING ON THE APPLICATION. The compounded polymeric materials were chopped into pieces fed into a mould of 462 mm by 462 mm with a thickness of 3 mm. ASTM D638 is the standard specification for plastics tensile testing.

ASTM D638 can be used for testing materials up to 14 mm 055 in in thickness. Manufactured accord- ing to ASTM D638 13 they were subjected to 120C and 140C for 1000 h so as to simulate the operating conditions in the engine compartment average tem-. ALL reinforced composites including MTS Systems Corporation highly orthotropic laminates shall use Type I specimens.

A 50 mm gauge length is recommended. Thickness of the specimen must be measured three times with the median value being the accepted value. The most commonly tested shape is a die cut C dogbone specimen which calls for an overall length of 115 mm the gauge length being 25 mm width of 6 mm and thickness of 3 mm.

Many offshored plastics manufacturing operations are returning with the energy and oil revolution. United has done virtually all the work for our customers when it comes to performing the ASTM D638 test procedure. 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.

All dimensions in mm 36. 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. This test method uses standard dumbell or dogbone shaped specimens under 14mm of thickness.

Flat specimens are typically molded die-cut or machined into a dogbone or dumbbell shape which ensures that the break occurs in the center of the specimen rather than at the clamping areas.

Type I specimens have an overall length of 165 mm and width of 13 mm with a gauge length of 50 mm.

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. A universal testing machine tensile testing machine is needed to perform this test. 14000 Technology Drive Eden Prairie MN 55344-2290 USA NOTE.

VTEC Laboratories offers a state-of-the-art ASTM D638 testing lab as well as the capacity to perform aging and weathering tests for a comprehensive picture of a materials present and future capabilities. The dumbbell dimensions are modulated as a function of the materials thickness. A 50 mm gauge length is recommended.

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. All customers need to do is determine which sample type they will be testing. Learn more News Events Shimadzu has released the MIV-X Ultrasonic Optical Flaw Detector.

ASTM D638 is one of the most common plastic strengthspecifications and covers the tensile properties of unreinforced and reinforced plastics. Type V ASTM D638 Specimen Dimensions Read more Five types of specimens Type I is recommended Type II is used if break does not occur within the parallel section of Type I Type V is used for special circumstances such as testing in a thermostatic chamber In addition other shapes are specified such as tube and rod shapes Type IV. Last previous edition approved in 2010 as D638 - 10.
