This blog explores the importance of ASTM D638 in a tensile testing machine, meant for plastic specimens. It shows how a UTM plays an important role in extracting meaningful material performance data.
See what your plastic material can really withstand. Start with the right testing approach from Testron’s UTM.
Introduction
Plastic manufacturing is not an uncommon factor in the industrial revolution. It is significant across several countries, and it is a global-tier manufacturing sector that many industrialists are focusing on the most.
To get valid and compliant products, it is necessary to comply with valid manufacturing protocols. The ASTM D638 is a valid tensile testing standard. It provides a recognized method for determining tensile properties of plastics.
Testing Range of A Universal Testing Machine for Plastics
A universal tensile testing machine is a useful tool that applies controlled force to a plastic sample and records responses by conducting the following tests:
- Tensile strength
- Elongation
- Yield behaviour
- Elastic modulus
- Deformation
- Breaking behaviour
- Force-displacement behaviour
- Stress-strain behaviour
Two plastics can have similar tensile strength but very different elongation. The tensile testing equipment from Testron Group has helped manufacturers to assess plastic and rubber materials. Our UTMs support ASTM D638 and ISO 527 among the list of supported testing standards.
It’s time for you to measure more than the breaking force. Build a complete plastic material testing workflow.
The Simple Definition of ASTM D638 in UTM
A tensile testing machine is validated with ASTM D638. That’s how it shows quality for the following test results of plastic materials:
- Tensile property data for control
- Specification
- Characterization
- R&D sectors
In the case of ASTM D638, the standard controls specimen preparation and test conditions. It provides meaningful comparative results.
How Does ASTM D638 Tensile Testing Work?
The complete procedure that ASTM D638 specifies for the tensile test apparatus is mentioned below:
- Step 1: Prepare the plastic specimen
- Step 2: Condition the specimen
- Step 3: Measure the specimen
- Step 4: Mount the specimen
- Step 5: Set the test method
- Step 6: Apply tensile force
- Step 7: Record force and deformation
- Step 8: Analyse the curve
- Step 9: Record the result
ASTM verifies three major parameters of specimen testing, starting with preparation, speed, and environment. Without the proper regulations, the tensile test equipment won’t provide an accurate result.

Single Column vs Double Column Universal Testing Machines
At Testron, users find unique universal material testing machines. That’s why they need to verify what they need to conclude the testing.
Let’s understand the differences between single column and double column UTMs:
Single-column systems
Best for the following uses:
- Compact laboratories
- Lower-force applications
- Research
- Education
- Small specimens
- Routine material testing
At Testron, these single-column models range from 50 N through 5 kN, plus a 1,000 N and 2,000 N model in the same category.
Double-column systems
Best for the following uses:
- Larger testing spaces
- Greater structural capacity
- Higher-force laboratory work
- Broader material applications
At Testron, the range of UTMs starts at 2 kN, 5 kN, 10 kN, and 20 kN.

How to Think About Universal Testing Machine Price
It is not recommended to choose the lowest UTM price. A bad or cheap investment won’t provide accurate and repeatable testing. Instead of investing in poor devices, it is wise to go with Testron’s premium UTMs with premium features.
The entire pricing, benefits, and ROI are dependent on the following factors:
- Machine architecture
- Maximum force
- Servo system/Hydraulic system
- Load cell & Accuracy
- Extensometer
- Grips & Software
- Test chamber & Automation
- Installation to universal testing machine calibration
- Training, Service, and Warranty
All of the above can be yours when you choose Testron’s compliant devices.
