The tensile testing machines are available in two types, single column and dual column. If we have to select the single column vs dual column universal testing machine, it depends on the free space in the lab, cost, and load capacity range from 0.5KN to 10KN.
What is A Single Column Universal Testing Machine?
Single Column Universal Testing MachineBest Applications for Single Column Testers
A single column tensile testing machine is designed for low tensile force; it works well for the range of 0.5KN to 5KN. Although the tester has the maximum capacity of up to 10 KN, such as Darong YG(B)026SH, the accurate results can be obtained up to 5KN.
Single column tensile testers are widely used in textile laboratories for determining the tensile strength of woven fabrics, garments, yarn, and lightweight knitted fabrics. This tester has a simple structure and covers low-pressure in the lab.
A tester is used to measure the tensile strength, tear strength, breaking point, elasticity, thread slip, and other mechanical properties of textiles. Darong’s single column tester YG(B)026SH complies with international standards ISO, GB/T, FZ/T, JIS, DIN, BS, and ASTM.
For testing on single column tensile testing machine, we use the specimen with size of 50 × 330 mm a rectangular strip. The tester’s speed can be adjusted from 0.001 to 1000 mm/min to get accurate results.
Overall, when we select the Single Column vs Dual Column, by cost and ease, the single column machines are most suitable.
Key Benefits of Single Column Tester
Compact Size
It is ideal for laboratories with limited space for a working area.
Cost effective
Single column tester has a lower manufacturing cost compared to the dual column, due to its simple frame.
Easy installation & setup
Its simple setup makes it easy to install and get operational quickly.
Best for Lower tensile range materials
It is designed specifically for low-force-range materials and delivers the best results in the 0.5-5 KN range.
Real-time monitoring
Darong’s YG(B)026SH tester features software integration that displays real-time deformation behavior.
What is A Dual Column Universal Testing Machine?
Dual Column Universal Testing MachineBest Applications for Dual Column Testers
Dual column tensile testing machine is designed for high tensile forces and works well over a range of 0.5 KN to 10 KN. This tester is specifically designed to handle materials with tensile strengths above 5 KN.
A dual column can measure the tensile strength of textile, plastic, rubber, leather, paper, and packaging materials. It can withstand the higher loads safely during testing due to its dual column frame structure.
Darong’s double column tester YG(B)026HC complies with international standards ASTM D4964, ASTM D5587, ASTM D5035, ISO13934.1/2, and JIS L1096.
You can set the test parameters, such as grip distance, test speed, force unit, maximum load, number of cycles, specimen circumference, and customer-specified elongation percentage, manually according to standard or customer requirements.
Before starting the tensile test, measure the initial gauge length, from the top of the upper pin to the bottom of the lower pin. Add the initial gauge length in the system’s software, and the instrument will automatically adjust the required gauge length.
For testing on the dual column tensile tester, we use the specimen with a size of 75 × 350 mm, with five warp and five weft samples. The specimen is sewn in a circle with a 10-inch circumference. The seam is positioned in the center of the specimen.
You can see the live test result in the form of a graph with the help of the integrated software. So, in high load tensile test conditions, if we compare Single column vs Dual Column, from a stability perspective, the dual column machines are most suitable.
Key Benefits of Dual Column Tester
High tensile force capacity & stability
The dual column tester can easily test up to 10 KN due to its stable double frame structure, which provides rigidity and support for high-load applications.
Superior alignment & reduced deflection
This tester avoids the risk of frame bending during high-load tensile tests.
Wide testing range
This is an ideal instrument for testing a wide range of mechanical properties, such as tensile, tear, compression, stretching, bending, elasticity, and elongation.
Large specimen accommodation
There is a large distance between the two columns, and it has a larger gauge length, allowing for testing specimens of greater size.
Long machine lifespan
It can withstand high load tensile force and mechanical fatigue better than a single column design.
Capacity-Wise Selection of Single Column vs Dual column testing machines
When to Use a Single Column Machine?
This machine is helpful for low-tensile-force testing and for lighter materials. It can test up to 5 KN, without the risk of frame bending. If there is less space in the lab, then a single column is a good option.
When to Use Dual Column Machines?
These machines are built to analyze the testing values for larger or heavyweight samples. Its strong vertical dual pillar reduces the movement of the frame, which provides us with better and more accurate results.
It is suitable for tensile testing up to 10 KN on geotextiles, industrial fabrics, and other technical textiles.
Concluion
In industries, while selecting single column vs dual column, the dual column gives stability for higher tensile loads up to 10 KN, while the single column takes less space, cost-effective, and can test up to 5 KN tensile load.
FAQs
What is the main difference between a single column and a dual column universal testing machine?
Single column universal testing machine is used for low-force testing and for lighter materials, while dual column is used for heavier materials such as industrial fabrics.
Which universal testing machine is better for small textile QC laboratories?
Single column is better for low space and cost-effective conditions.
Why are dual column testing machines preferred for industrial fabrics and geotextiles?
Because the dual column universal testing machine has a higher load capacity, ranging up to 5KN.
