At the heart of the AMETEK LLOYD LS5Plus Material Testing Machine lies a robust mechanical design that combines high force capacity with meticulous precision—hallmarks of the AMETEK LLOYD Material Testing Machine family. With a 5 kN force rating, the AMETEK LLOYD LS5Plus Material Testing Machine expands beyond the capabilities of lower-capacity models, making it ideal for testing materials that require higher force input, such as thick engineering plastics, metal foils, and reinforced composites. This force capacity is paired with exceptional load accuracy: the AMETEK LLOYD LS5Plus Material Testing Machine achieves ±0.5% accuracy from 1% to 100% of its load cell range, a wide dynamic range that reduces the need for multiple load cells and simplifies setup for diverse tests.  

 

A key mechanical advantage of the AMETEK LLOYD LS5Plus Material Testing Machine is its extended crosshead travel, typically 1500 mm (59.1 in) as standard—ample space to accommodate high-elongation materials like elastic rubbers or stretchable films that require significant deformation before failure. The crosshead speed range further enhances versatility, spanning 0.01 to 2500 mm/min (0.0004 to 98.4 in/min) with a maximum return speed of 2500 mm/min. This range allows for both slow, controlled tests (eg, creep studies on structural plastics) and high-throughput QC checks (eg, batch testing of fasteners), optimizing productivity across use cases.  

 

Environmental control accessories further extend the AMETEK LLOYD LS5Plus Material Testing Machine’s capabilities. An optional temperature chamber enables testing across a range of -70°C to 200°C, critical for evaluating how materials perform in extreme conditions (eg, automotive plastics in cold climates or electronics components in high-heat environments). Safety features, such as adjustable splinter shields with electrical interlocks, protect operators during sample failure—especially important when testing brittle materials like certain composites or glass-reinforced plastics. These accessories ensure the AMETEK LLOYD LS5Plus Material Testing Machine can adapt to nearly any testing scenario, from routine QC to cutting-edge R&D.  

 

which records up to 10 kHz of data to capture transient events like sudden sample failure. Real-time graphs (eg, stress-strain, force-displacement) update during testing, allowing operators to monitor progress and identify anomalies. A unique feature of NEXYGENPlus is its video and still image capture capability: connecting a webcam to the PC lets users record sample behavior, which can be synced with test data to visualize failure points (eg, crack initiation in a composite). This is invaluable for R&D teams analyzing material performance and QC labs documenting test results for compliance.  

 

Data management is seamless with the AMETEK LLOYD LS5Plus Material Testing Machine and NEXYGENPlus. The software integrates directly with Microsoft Office® (Excel, Word) for easy report generation and exports data to LIMS (Laboratory Information Management Systems) or SPC (Statistical Process Control) tools—critical for regulated industries like medical devices or aerospace. Built-in SPC functionality monitors process parameters (eg, Cp, Cpk) to identify trends in manufacturing quality, helping teams optimize production. For high-volume testing, batch testing automation allows the AMETEK LLOYD LS5Plus Material Testing Machine to run multiple samples sequentially without operator intervention, maximizing efficiency.  

 

 

To fully leverage the AMETEK LLOYD LS5Plus Material Testing Machine’s capabilities, it is essential to understand the testing principles that govern its operation. At its core, the AMETEK LLOYD LS5Plus Material Testing Machine applies controlled force or displacement to a specimen, measures the material’s response (deformation, failure), and uses that data to calculate key properties—all while adhering to standardized protocols. Below are the principles behind its most common test types, tailored to the AMETEK LLOYD LS5Plus Material Testing Machine’s 5 kN capacity and precision.  

 

Tensile testing evaluates a material’s ability to resist pulling forces, measuring properties like tensile strength, yield strength, and elongation at break. For the AMETEK LLOYD LS5Plus Material Testing Machine:  

A specimen (eg, a dog-bone-shaped plastic or metal sample) is clamped in the machine’s grips.  

The crosshead moves upward at a controlled speed (set via NEXYGENPlus), applying axial tensile force.  

The AMETEK LLOYD LS5Plus Material Testing Machine’s load cell measures the applied force, while an extensometer tracks specimen elongation.  

NEXYGENPlus calculates stress (force ÷ initial cross-sectional area) and strain (elongation ÷ initial length), generating a stress-strain curve. Key properties are derived from this curve: tensile strength (maximum stress before failure), yield strength (stress at which plastic deformation begins), and elongation at break (percentage of stretch at failure).  

The AMETEK LLOYD LS5Plus Material Testing Machine’s 5 kN capacity is critical here—it can test high-strength materials like carbon fiber composites or thin metal sheets that require more force to reach failure than lower-capacity machines can provide.  

 

Compression testing assesses a material’s resistance to crushing, measuring properties like compressive strength and modulus. For the AMETEK LLOYD LS5Plus Material Testing Machine:  

A specimen (eg, a cylindrical plastic block or foam sample) is placed between compression platens.  

The crosshead moves downward at a controlled speed, applying compressive force.  

The load cell measures the force, while the AMETEK LLOYD LS5Plus Material Testing Machine’s displacement sensor or an extensometer tracks the specimen’s compression (reduction in height).  

NEXYGENPlus generates a force-displacement curve, calculating compressive strength (maximum force before failure, eg, cracking or buckling) and compressive modulus (stiffness under compression).  

This test is vital for materials like packaging foams (to evaluate cushioning) or concrete aggregates (to test load-bearing capacity), and the AMETEK LLOYD LS5Plus Material Testing Machine’s high force capacity ensures it can handle dense, rigid specimens.  

 

Flexural testing (bending testing) evaluates a material’s ability to resist bending, critical for structural materials like beams or panels. For the AMETEK LLOYD LS5Plus Material Testing Machine:  

A specimen (eg, a plastic beam or composite panel) is supported at two ends (3-point) or four ends (4-point) using a bending jig.  

The crosshead applies a downward force at the midpoint (3-point) or between inner supports (4-point), creating a bending moment.  

The load cell measures the force, while an extensometer tracks the specimen’s deflection (bending) at the midpoint.  

NEXYGENPlus calculates flexural strength (maximum stress at the outer fiber of the specimen) and flexural modulus (stiffness in bending). The 4-point test is particularly useful for materials with uneven properties (eg, reinforced plastics), as it distributes stress more evenly than the 3-point method.  

The AMETEK LLOYD LS5Plus Material Testing Machine’s stiffness ensures minimal machine deflection during testing, preserving the accuracy of flexural data—essential for R&D teams designing structural components.  

 

Friction testing measures the force required to slide two surfaces against each other, used to evaluate properties like coefficient of friction (COF) for materials like packaging films or mechanical components. For the AMETEK LLOYD LS5Plus Material Testing Machine:  

One specimen is fixed to the worktable, and the other is attached to a grip connected to the load cell.  

The crosshead moves at a controlled speed, sliding the upper specimen across the lower one.  

The load cell measures the frictional force, while NEXYGENPlus calculates COF as the ratio of frictional force to normal force (weight of the upper specimen or applied downward force).  

This test is critical for industries like packaging (to ensure film slips properly on conveyor belts) and automotive (to evaluate brake pad friction), and the AMETEK LLOYD LS5Plus Material Testing Machine’s precise speed control ensures consistent sliding conditions.  
 

These tests evaluate long-term material behavior under sustained loads, critical for applications like structural plastics or rubber seals. For the AMETEK LLOYD LS5Plus Material Testing Machine:  

Creep Testing: A constant force is applied to the specimen, and the AMETEK LLOYD LS5Plus Material Testing Machine measures deformation over time (hours to weeks). NEXYGENPlus records creep strain (deformation ÷ initial length) vs. time, identifying creep rate (deformation speed) and creep rupture (time to failure).  

Relaxation Testing: The specimen is stretched to a constant deformation, and the load cell measures how force decreases over time (material “relaxation”). NEXYGENPlus calculates relaxation modulus (stress ÷ strain at a given time) to assess long-term tension retention.  

The AMETEK LLOYD LS5Plus Material Testing Machine’s stable force control and high-resolution data capture ensure accurate long-term measurements—essential for materials used in long-service-life products like pipelines or medical implants.  

 

The AMETEK LLOYD LS5Plus Material Testing Machine represents the pinnacle of versatility and precision in the AMETEK LLOYD Material Testing Machine lineup, bridging the gap between high-force testing needs and meticulous data capture.
