Some specimens cannot be tested standing up. Strand, cable, chain, webbing and pipe need travel measured in metres rather than centimetres, and a vertical column has nowhere to put it. A horizontal frame lays the test out along the floor instead. NextGen builds horizontal machines for that work, verified to ISO 7500-1 and ASTM E4.

The frame carries long travel while keeping the load path straight, and takes the same grips, load cells and software used across the rest of the range, so methods and records stay consistent with the vertical machines beside it. Installation, calibration and operator training are done on site, and support continues for the life of the frame.

What Horizontal Tensile Testing Measures

A horizontal machine measures the same properties as a vertical frame, tensile strength, proof load, elongation and breaking force, on specimens that are too long, heavy or awkward to lift into a column. Wire rope, cable, chain, rebar, slings, fasteners and structural components lie along the test bed and are loaded in a straight line. The system can be run in closed-loop control of force, displacement and extension, and common results include tensile strength, proof load, elongation and deformation behavior under controlled loading. The horizontal layout provides more usable test length, easier specimen handling and better access for custom grips and fixtures.

Standards for Long-Specimen Testing

The NG-EML Series H can be configured for ASTM E8/E8M and ISO 6892-1 for metals, ASTM A370 for steel products, ASTM A931 and ISO 3108 for wire rope and strand breaking force, and EN ISO 15630-1 for reinforcing bars, rod and wire. Force verification follows ASTM E4 and ISO 7500-1. Applicable methods depend on the specimen type, force capacity, grips, extensometer setup and reporting procedure.

What Affects Horizontal Test Results

Ropes, chains and slings are assemblies rather than simple straight specimens, so the end fittings and fixtures decide whether the breaking force is measured at all. Fixtures are chosen for the specimen shape and loading direction and can include pin-type grips, wedge grips, rope and cable fixtures, chain fixtures, hook and shackle fixtures and rebar fixtures. Test length, stroke and test width must suit the longest specimen, and because these specimens can release stored energy at failure, the guarding around the test area is part of the test setup.

Horizontal Testing Machines from NextGen

The NG-EML Series H is configured around the application, with reference capacities from 200 kN to 5,000 kN. The H-205 is an electromechanical screw-driven machine for lower-force long specimens, the H-206 is an electro-hydraulic machine at 2,000 kN for chains, hooks, wire rope and rebar, and the H-506A is a 5,000 kN hydraulic machine for steel wire ropes, fiber ropes and slings. Force capacity, test bed length, stroke, grips, guarding and software can be adapted to the specimen and the room. Force reading accuracy is within 1 percent, Class 1, with a resolution of 1/500,000 of full scale.

For Laboratories

One partner to equip your complete metals laboratory

A horizontal frame covers one part of a metals laboratory. NextGen equips the rest of it too, from impact and hardness testing to metallography and specimen preparation, and stays responsible for it after delivery.

FAQs

Choose horizontal when specimen length, weight, geometry or expected elongation makes vertical testing impractical. Strand, cable, chain, webbing and pipe need travel measured in meters, and a horizontal bed lets long products lie along the frame instead of being lifted into a column. It also improves loading access and supports guarding for high-force breaking tests.

Supported methods include ASTM E8/E8M and ISO 6892-1 for tension, ASTM A931 and ISO 3108 for wire rope breaking force, and EN ISO 15630-1 for reinforcing bars. Force is verified to ASTM E4 and ISO 7500-1. Force reading accuracy is within 1 percent, Class 1.

The test area can be fitted with protective shielding or a fully enclosed protective frame, depending on force capacity and specimen type. Safety functions can include overload protection, travel limits, emergency stop controls, guarded test areas and protective covers for breaking load tests, which matters for ropes, chains, cables and slings that can release stored energy at failure.

Force capacity, test bed length, crosshead or cylinder stroke, test width, grips, fixtures, guarding, control system and reporting can all be adapted to the specimen geometry, the test method and the facility layout, and custom capacities are available beyond the reference range. Describe your specimen and force for a configuration.

The H-205 is a 200 kN electromechanical screw-driven machine with a maximum sample length of 3,000 mm. The H-206 is a 2,000 kN electro-hydraulic machine with a tensile space of up to 5,000 mm, and the H-506A is a 5,000 kN hydraulic machine with 600 to 5,000 mm of tensile space. All three are reference configurations and can be adapted.
