Astm standards for tensile testing series#
This machine is simple to operate, especially suitable for controlling quality in the production line, this series of machine is mainly applied to test the non-metallic and metallic materials which the load is less than 30ton. VEW 2302 Computer Servo Type Universal Testing Machine is a new material testing machine that combined with the electronic technology and mechanical transmission, it has accurate load speed, range of force measurement, has high accuracy and sensitivity for the load, displacement measurement and control, it also can be tested the constant-velocity loading, constant- velocity displacement. We also recommend using a dual-column floor type machine. We recommend to use UTM machines with a capacity of 50kN-100kN, it depends on the strength of the materials. Below is a type of extensometer that can be used when performing tensile tests on metallic materials. It also to determine properties at lower strain values, such as modulus or yield, and a slightly lower-accuracy device for high strain values, such as uniform elongation or total elongation.

When performing a tensile test on metallic materials it requires a high-accuracy device to measure the deformation of metallic materials. This is because the specimen is pulled more tightly into the narrowest area of the wedge and it will be increasing the gripping pressure.ġ. Wedge grips are a popular option to be used for tensile testing on metallic materials. Used for high strength tensile testing, suitable for a flat and round specimen. These mechanical grips are designed to self-tighten as the tensile test progresses. For each of these specimen types, we need to use a good and appropriate grip.ġ. These test standards allow for many different types of specimens such as dogbone-shaped, bar, tube, sheet, plate, wire, rod, pipe, and tube. For testing rectangular type specimens, it uses a flat-shaped inside grip while to test round specimens, it uses a curved inside grip. The most common types of E8/E8M specimens are rectangular and round. The following are the properties of tensile commonly measured through ASTM E8/E8M: Tensile strength tests can be performed on using Universal Testing Machine (UTM) and also known as a tensile testing machine.

This ASTM is divided into two separate standards which are E8 for imperial unit users and E8M for metric users. This test information is useful in comparisons of materials, alloy development, quality control, and design under certain circumstances. The Malaysian government has also adopted this standard.īasically, ASTM E8/E8M measures the strength and ductility of metal, steel, alloy and other materials under uniaxial tensile stresses. In Malaysia, most industries use the ASTM E8/E8M standard in their companies. Nowadays, ASTM standards are highly preferred by both corporate or government bodies. Manufacturing industries such as automotive, metal, alloy, building construction and others often use this standard. Among the ASTM standards that are often used in the industry is ASTM E8/E8M.ĪSTM E8/E8M is an international test standard designed for tensile testing of metallic and steel materials at room temperature (ambient temperature) between 10☌ to 38☌ (50 to 100 degrees Fahrenheit). The purpose it was introduced to the industry is to publish technical standard agreements for various materials, product, systems and others.
