Summary

A universal testing machine plays an important role in ensuring consistent mechanical testing results of tensile, compression, bend, and other tests on materials. This blog post discusses repeatability factors such as accuracy, specimen preparation, grips, loading, and software with regard to machines manufactured by USA-based companies and pipe testing.

Introduction

While measuring material strength is key to manufacturers, laboratories, and research centers, it is also important to have repeatable results from their tests. A test result is relevant and valuable only if the same material will provide the same test results under similar testing conditions.

A universal testing machine in the USA enables you to test a variety of properties of materials such as tensile, compression, and flexure. Using appropriate grips and fixtures, as well as load cells and software, it becomes possible to test metals, plastics, polymers, composites, rubber, and piping materials on one universal test machine.

For USA manufacturers seeking quality material testing solutions, choosing the proper equipment would definitely help increase the efficiency of your laboratory.

How Does a Universal Testing Machine in the USA Increase Repeatability?

Repeatability is achieving the same results when repeating the same test under the same conditions on a universal testing machine in the USA. A number of aspects play a role here.

1. High Precision in Force Measurement

The load cell is the key part of the universal tensile testing machine. With accurate force measurement, it will be possible to determine such parameters as tensile strength, compression force, yield strength, etc.

Proper selection of the capacity of the load cell is also important to retain the measurement resolution during the test.

2. Constant Crosshead Displacement Speed

The testing speed could affect the material response. In the case of the modern universal tensile strength testing machine and universal testing machine in the USA, the displacement of the crosshead controls the speed of the test. 

Constant displacement speed decreases the variations between the tests and helps laboratories to follow the standard testing procedure.

3. Proper Specimen Alignment

Any bending or non-uniform loading could result from misalignment. Therefore, correct preparation and alignment of the specimen is important to achieve repeatability of the test.

Grips and fixtures make the universal material testing machine applicable for various specimens and their shapes.

4. Digital Data Acquisition

In today’s universal testing machine systems, force, displacement, strain, and other test data can be acquired digitally. The digital acquisition of data ensures accuracy and facilitates comparisons across batches.

In the laboratory setting where research and quality control are involved, the stored test data is valuable for traceability purposes.

Tensile Test Using the Universal Testing Machine in the USA

Tensile testing is an examination of a material’s response to being pulled. Properties tested using tensile testing will include the tensile strength, yield strength, and elongation, among others.

In metal materials, ASTM E8/E8M specifies the procedure for the tensile test, for which the properties that will be determined include yield strength, tensile strength, elongation, and reduction of area.

Plastics’ tensile test procedure for standard dumbbell specimens is outlined by ASTM D638.

This will make the universal strength testing machine handy for laboratories handling different categories of materials.

Compression Testing Using the Universal Test Machine

Compression testing is the process of testing a material or component subjected to compressive loading. This can be done in different areas such as materials, components, packaging materials, polymers, etc.

A universal testing equipment that is already being used for tensile testing can be easily converted for use in compression testing using proper settings.

Repeatability in testing involves factors other than the accuracy of the machine alone. Some of the other important factors include specimen dimensions, condition, alignment, speed, fixtures, and environment.

Universal Testing Machine in the USA for Pipe Testing Applications

Pipe production companies and testing laboratories have mechanical testing needs specific to pipes. A testing machine for pipe tests or a universal testing system set up to conduct pipe tests can be a part of a wider pipe testing equipment suite.

The testing program will differ depending on the application and can include tensile testing, compression testing, pipe components, or mechanical testing of specimens.

A laboratory that caters to the plastic pipe industry can combine the use of the universal testing machine in the USA with other equipment like hydrostatic pipe testers, pipe impact testers, carbon black dispersion testers, and other pipe testing equipment provided by a universal testing machine manufacturer or universal testing machine supplier.

This is especially true when there is a desire to have a comprehensive testing setup rather than one testing process.

Universal Hydraulic Testing Machines vs. Universal Electronic Testing Machines

It is up to the user to determine whether to use hydraulic universal testing machines or an electronic universal testing machine based on force and application for their universal testing machine in the USA setup.

While hydraulic testing machines are good for applications that need large forces, electronic machines are good for controlled movement and measurements in low- and medium-force tests.

Thus, it is recommended that buyers analyze all the factors mentioned above before making their selection.

What Determines Universal Testing Machine Cost?

The universal testing machine cost is determined by many configuration issues rather than the name of the machine.

Key issues to consider are

• Maximum load capacity
• Frame configuration of machine
• Hydraulic or electronic version
• Load cell capacity
• Specified extensometers
• Tensile and compression fixturing
• Software/Data Acquisition
• Automation
• Pipe/Material Specimen Fixturing

As a result, the universal testing machine cost should be determined based on the whole testing application rather than just the machine cost itself.

Provide details regarding your material, sample size, load requirement, and testing requirements to Testron to assist you in selecting the appropriate UTM for your laboratory in the USA.

Why Should You Consider Testron as a Universal Testing Machine Manufacturer?

In choosing a universal testing machine manufacturer, it isn’t just about comparing equipment specifications. Technical consultation, configuration, installation, training, and after-sales services can play crucial roles in determining how user-friendly the equipment will be.

As seen on Testron Group’s product page for the USA, their UTM systems are described as solutions for tensile, compression, bending, and shear testing, which come in hydraulic, electronic, or servo configurations. Technical consultation, customization, installation, and calibration assistance are some of the additional factors that they offer.

For businesses looking for a universal testing machine provider in the United States, application-specific configuration becomes especially relevant when dealing with various materials or pipes.

Conclusion: Make Your Testing Consistent With Quality Assurance

A universal testing machine in the USA can provide the basis for a repeatable tensile and compression test setup when the machine, fixtures, samples, testing speed, alignment, and data acquisition process are well-controlled.

For manufacturers and laboratories, an appropriate universal material testing machine can be useful for quality assurance, research & development, characterization, and special tests. For pipe manufacturers, it can also be complemented with a dedicated pipe testing machine and a wider range of material testing solutions.

When assessing the cost of a universal testing machine, take into account the entire system setup, standards, application, fixtures, software, and testing needs.
