Tighten the grips evenly and firmly to the degree necessary to minimize slipping of the specimen during testing. Active view current version of standard. When an extensometer is used, record load versus extension of the test area measured by the extensometer.

A preload eliminates the compressive forces on a specimen that often occur when initially placed into grips.
The matching width allows for ease of specimen alignment, which is critical for good breaks and accurate test results. D88 Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Next Checking to see if you are a returning visitor…. How to Build a New Test. The following calculations can be made from tensile test results:. The size of the chamber places a limitation on the maximum elongation that can be reached. Specimen gripping Accurate strain measurement Reporting calculations in compliance with the standard Instron's Solution: It is used to evaluate materials that are subjected to heavy abuse or that can asstm web transport equipment in the event of a machine malfunction in end-use applications.
Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.
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.
aztm Tighten the grips evenly and firmly to the degree necessary to minimize slipping of the specimen during testing. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Pneumatic grips are used as a matter of convenience when testing but are not required.
ASTM D882-12 Tensile Testing of Thin Plastic Sheeting
Referenced Documents purchase separately The asmt listed below are referenced within the subject standard but are not provided as part of the standard. Elongation and tensile modulus can be calculated from crosshead displacement, or with an extensometer. You can open the pneumatic grips with finger toggles or foot pedals. Link to Active This link will always route to the current Active version of the standard.
If tensile energy to break measurements is being determined, provision must be made for integration of the d82 curve. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. This test is very similar to the common ASTM D test whereby plastic material is pulled until in breaks in order to measure elongation, tensile modulus, tensile yield strength, and tensile strength at break.
Consequently, where precise comparative results are desired, these factors must be carefully controlled.
Tensile Properties (Sheet) ASTM D
Automotive Interior Mechanical Testing Guide. In that sense, caution is advised in utilizing TEB test results for end-use design applications.
It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. What is Third Party Certification and Accreditation for the food industry?
Standard test fixtures are installed inside the chamber, and testing is conducted inside the controlled thermal environment the same as it would be at ambient temperature. Inspection Validating the specifications, value and safety of your raw materials, products and assets. As a delicate challenge, thin plastic sheeting can be difficult to test without bending and slipping. Planar Biaxial Testing Guide.
The most common face size for this type of material is 25 mm x 25 mm 1 in x 1 in.
ASTM D Tensile Testing of Thin Plastic Sheeting - Instron
Validating the specifications, value and safety of your raw materials, products and assets. When different materials are being compared for stiffness, specimens of identical dimensions must be employed. Note 3—The modulus determination is generally based on the use of grip separation as a measure of extension; however, the desirability of using extensometers, as described in 5.
Due to the flexible, delicate nature of these plastic specimens, both gripping and strain measurement can be a challenge. The rubber coating prevents the film from prematurely breaking at the grip edge and also keeps it from slipping.
