TRViewX is an advanced non-contact extensometer that offers high-measurement accuracy, is capable of measuring width changes, and is applicable to a wide variety of materials testing applications. In particular, due to the non-contact design, TRViewX is perfect for measuring films, foils, and other thin or narrow materials without affecting the specimen during testing. Furthermore, TRViewX can be used to measure displacements during atmosphere-controlled testing in a thermostatic chamber. TRViewX provides high-accuracy measurements in accordance with ISO 9513 Class 0.5 and JIS B 7741 Class 0.5 for elongation measurements and ISO 9513 Class 1 and JIS B 7741 Class 1 for width measurements. It is compliant with plastic tensile testing standards, including ISO 527, JIS K7161, and ASTM D638, even supporting 75 mm gauge length specimens (type A1 specimens) specified in ISO 527 and JIS K 7161.
To determine the suitability of a material for an application where it is under load, measuring its elongation is important. Measuring elongation enables determination of the elastic modulus (reversible elongation in the elastic region) by measuring the small initial elongation range, and determination of elongation at specimen failure, by measuring larger irreversible elongation in the plastic region. Shimadzu’s SIE-560A series automatic extensometers accomplish both of these measurements with high accuracy, and provide automated functions that increase testing efficiency and test reproducibility. Ideal for testing a wide variety of materials, including metallic materials, plastics, and composites, the SIE-560A series complies with ISO 527, JIS K 7161, and ASTM D638 standards for plastics tensile testing. In addition, the SIE-560A series supports strain-rate controlled metallic material tensile testing measurements specified in ISO 6892, JIS Z 2241, and ASTM E4
A Long-Travel Extensometer That Is Now Easier to Use and Even More Precise The DSES-1000 is a long-travel contact-type extensometer able to measure displacement up to the breakpoint in tensile tests of rubber and other soft materials. The upper and lower arms are clamped to respective gauge positions using a simple single operation, with each arm tracking sample elongation independently.
The SSG-H series of strain gauge extensometers are compliant with ISO, JIS, and ASTM tensile test standards for hard plastics and metal materials Featuring a wide elongation measurement range with the ability to measure using small gauge lengths, these lightweight, clip-on strain gauge extensometers attach to both rod and flat plate specimens.
Shimadzu’s SSG series of strain gauge extensometers are compliant with ISO, JIS, and ASTM tensile test standards, including those for plastics and metallic materials These lightweight, precision extensometers feature a wide elongation measurement range, while retaining the flexibility to measure using small gauge lengths, and support both rod and flat plate shaped specimens. Consisting of an elongation sensor and amplifier, this extensometer is suitable for use with metals and hard plastic materials, and is fastened securely to specimens with screws. Calibration using an extensometer calibrator allows the extensometer to meet JIS and ISO Class 0.5 and ASTM Class C standards for higher accuracy.
ISO Class 1 Compliant Differential Transformer Type Extensometers The ISO 6892-1 standard for tensile testing of metallic materials prescribes Class 1 or higher extensometers, and JIS Z2241 prescribes Class 2 or higher extensometers when measuring withstanding pressure. The DT series includes Class 1 compliant differential transformer type extensometers, which can be used to implement test methods compliant with metal tensile test standards.
After tensile testing, flexural tests are the most common strength tests for plastics and other resins. The main standards for plastic flexural (bend) tests are ISO 178, JIS K 7171, and ASTM D790, which require very accurate test systems. These standards include flexural strain measurements using a deflectometer, ranging from micro-strain measurements in the elastic region, the reversible elongation at the beginning of tests, to larger strain measurements in the plastic region. Shimadzu's deflectometers integrate easily into AG-X plus series, AGS-X series, and EZ-X test frames and Trapezium X testing software. Since these deflectometers push up against the specimen from below, the specimen color is not a limiting factor, as can be for laser type non-contact deflectometers. Furthermore, these deflectometers can partially absorb the shock during specimen failure, preventing specimen fragments from scattering.
Manual non-shift wedge grips are versatile grips for tensile testing a wide variety of materials, including metals, plastics, and composites. The open-front design allows easy insertion of specimens and exchange of grip faces. The self-tightening action means samples are held firmly within the grip faces, minimizing slippage during testing.
Pneumatic non-shift wedge grips have an open-front design and use one-touch chucking by foot operation to provide simple specimen mounting. These grips are suitable for tensile testing materials such as plastics and metals.
Hydraulic non-shift wedge grips combine the benefits of a strong, consistent clamping force with an open-front, wedge design and are ideal for tensile testing plastics, metals, lumber, and composites.
Screw flat grips are general-purpose grips used for static tensile testing of a wide range of materials, most commonly, rubbers, plastics, textiles, and paper, and specimens such as plates and wires. Another advantage of these grips is they can be used to test thick specimens, up to 16 mm (0.63 in).
10 N (2.2 lbf) screw flat grips are primarily used for tensile testing low force, soft materials such as yarn, paper, plastics, and cloth, in film or wire geometry. Grip faces are flat and rubber-coated, and the supplied coupling joints for the 10 N screw flat grips are designed for use on lower-capacity load cells.
For tensile testing rubbers, plastics, elastomers, textiles, cloth, and paper, in specimen geometries such as plates, films, and wires, a good option is pneumatic flat grips. Quick clamping and a repeatable clamping force are advantages of pneumatic flat grips.
These 1 kN pneumatic flat grips are designed for tensile testing metal foils. Unique grip features include a very rigid structure, which reduces swivel of the grip faces during testing, and specially shaped flat grip faces. As with all pneumatic grips, these grips allow quick specimen clamping with a repeatable clamping force.

Hydraulic flat grips have wide grip faces and a strong, symmetric clamping force, making these grips ideal for tensile testing heavy cloth. Two models of hydraulic flat grips are available: 10 kN (2,200 lbf) and 50 kN (11,000 lbf) capacity models.
Pantograph grips use a simple spring design to hold and apply pressure to specimens during tensile testing. These grips are mainly used for tensile testing plate specimens of rubber, textiles, or soft plastics.

These eccentric roller grips are specifically designed for tensile testing flexible materials, such as rubber and soft and semi-hard plastics. Named after the non-symmetric roller design, these grips employ a simple and quick clamping mechanism. They also have a self-tightening action, which maintains clamping of the specimen during testing regardless of any thickness reduction. In addition, the upper and lower grip faces are parallel grooved to help hold these soft materials.
Henry Scott grips are useful for clamping plate and tape specimens of soft, flexible materials for tensile testing. Specimens are held by rollers on the upper and lower grips, which feature a self-clamping action. To minimize specimen slippage, the grip body opposite the roller, where the specimen contacts, is curved and features a parallel-grooved surface. During tensile testing, the self-clamping action applies increasing clamping force to the specimen as the overall force increases to help hold the specimen in place.
This roller grip set includes both 200 N (44 lbf) and 1 kN (220 lbf) roller grips for tensile testing elastomeric ring specimens. The 200 N grips have a 4.5 mm (0.18 in) diameter roller. The diameter of the roller on the 1 kN grips is 25 mm (0.98 in).
Clip grips are easy-to-use and applicable for low force tensile testing of materials such as yarn and plastics. Both 10 N (2.2 lbf) and 50 N (11 lbf) clip grips have flat metal grip faces.
