Tension Testing / Tensile Testing Universal Testing Systems
ADMET material testing systems perform accurate and reliable tension tests / tensile tests. Our systems are ideal for measuring the tensile properties of metals, plastics, textiles, adhesives, medical devices and many other products and components. As they pull materials apart, ADMET testing machines accurately calculate mechanical properties such as tensile strength, peak load, elongation, tensile modulus, and yield.
Common tension testing standards include:
- ASTM D412 – Standard Test Methods for Vulcanized Rubber and Thermoplastic Elastomers – Tension
- ASTM D624 – Standard Test Method for Tear Strength of Conventional Vulcanized Rubber and Thermoplastic Elastomers
- ASTM D638 – Standard Test Method for Tensile Properties of Plastics
- ASTM D751 – Standard Test Methods for Coated Fabrics
- ASTM D882 – Standard Test Method for Tensile Properties of Thin Plastic Sheeting
- ASTM D1002 – Standard Test Method for Apparent Shear Strength of Single-Lap-Joint Adhesively Bonded Metal Specimens by Tension Loading (Metal-to-Metal)
- ASTM D1414 – Standard Test Methods for Rubber O-Rings
- ASTM D1708 – Standard Test Method for Tensile Properties of Plastics by Use of Microtensile Specimens
- ASTM D2256 – Standard Test Method for Tensile Properties of Yarns by the Single-Strand Method
- ASTM D5034 – Standard Test Method for Breaking Strength and Elongation of Textile Fabrics (Grab Test)
- ASTM E8 – Standard Test Methods for Tension Testing of Metallic Materials
- ASTM F2516 – Standard Test Method for Tension Testing of Nickel-Titanium Superelastic Materials

Tensile Testing Grips
Manual vise grips are versatile tensile grips for capacities of 50kN or less. Plastic, metal, fabrics, films, ceramics, and many other types of samples can be held in a vise grip. Vise grips jaw options include plain, serrated, rubber, diamond-coated, and v-notched faces.
Pneumatic tensile grips are available as either wedge or vise types. They allow for rapid sample changes and constant clamping force. Many types of samples like plastics, metals, fabrics, films, and ceramics can be held in a pneumatic grip. Jaw options for pneumatic grips include plain, serrated, rubber, diamond-coated, and v-notched faces.
Wedge grips are used to clamp samples that require a high clamping force. They are the preferred grips for ASTM E8 metals tension testing. The self-intensifying clamping mechanism allows holding samples at high forces. Moving-body wedge grips should be used to avoid compressive loads on the samples. ADMET wedge grips can be supplied with pull rods of different lengths to be used in environmental chambers.
Rope & Thread
Rope and thread grips are applicable for filaments, cords, yarn, fine wires, narrow ribbons, ropes, and similar materials. According to its friction coefficient, the specimen will be twisted one or more times around the guide roller before being fixed with clamping jaws. The guide rollers generate a slow, notch free stress relief to prevent the breakage of the specimen in the clamping area. Pneumatic versions available for most grip designs.
Ribbon & Webbing
Ribbon and webbing grips are applicable for tensile testing of webbings and ribbons. The webbing is fed through the center slot, the drum is rotated and then pinned to lock it in place. As the material is pulled it tightens on itself keeping it from slipping. The drums offer stress relief to prevent the breakage of the specimen in the clamping area.
Pinching grips are versatile and easy to use small tensile grips. They are suitable for small force pull and tear tests of components, adhesive bonds, plastic welds, and other low force applications and can be chain mounted for flexible positioning.
Hydraulic grips are high capacity grips for rigid materials. Hydraulic grip types can be vise, pneumatic, or wedge. ADMET offers hydraulic pumps that convert shop air to high pressure hydraulic force. Hydraulic grips may also be operated by the testing machine’s hydraulic system.
Self-tightening grips are ideal for materials that thin as they are stretched such as elastomers and other soft materials. They enable fast loading of plastics, fabrics, films, rubber, and similar materials.
