From Inquiry to Result: How We Conduct a Tensile Test at Obsnap Testing Services

At Obsnap Testing Services Sdn Bhd, we believe that transparency builds trust. Whether you are a first-time client or a returning partner, understanding what happens behind the scenes — from the moment you contact us to the moment you receive your test report — helps you make better decisions for your product and your business.

Here is our complete step-by-step tensile test process.

Step A — Customer Inquiry Received

It all starts with you. When you reach out to us, our team collects the basic information — your company name, contact person, and how urgently you need the results. No question is too small at this stage.

Step B — Understanding Your Requirement

This is the most important step. Before we touch any equipment, we need to fully understand your testing needs. We will ask:

• What material are you testing? (metal, plastic, rubber, composite)
• What standard applies? (ASTM, ISO, MS, or your own client specification)
• What are the dimensions? (thickness, width, gauge length)
• How many samples do you have, and what results do you need?
• Any special conditions? (specific test temperature or crosshead speed)

Getting this right upfront saves time and ensures your results are meaningful.

Step C — Quotation & Confirmation

Once we understand the scope, we prepare and send you a detailed quotation. Upon your approval and purchase order, we proceed with scheduling.

Step D — Sample Submission

You deliver your samples to our laboratory in Shah Alam, Seksyen 16. Our lab team immediately checks the condition, labelling, and quantity of every sample received.

Step E — Sample Preparation

Specimens are carefully machined to the required shape and dimensions — typically a dog-bone (flat) or round bar profile, depending on the applicable standard. Width and thickness are measured at three points, and the average is recorded for accuracy.

Step F — Machine Setup & Calibration

Our technicians select the correct grips and load cell suited to your material. The crosshead speed is set according to the standard (for example, 5 mm/min for metals per ASTM E8 or ISO 6892). Gauge length is confirmed, and the machine and extensometer are zeroed before testing begins.

Step G — Conducting the Tensile Test

The specimen is mounted securely in the upper and lower grips of the Universal Testing Machine (UTM). A tensile load is applied at the set speed — continuously — until the specimen fractures. Throughout the test, the machine captures Load (N) vs. Extension (mm) data in real time.

Step H — Observing & Recording Key Points

During and after the test, our team records:

• Yield Point — where the material begins to deform permanently
• Ultimate Tensile Strength (UTS) — the maximum load the material can withstand
• Fracture Point — where the specimen fully breaks
• Elongation & reduction of area — measured from the broken specimen

Step I — Data Analysis & Calculation

From the raw data, we calculate:

• Tensile Strength (MPa) = Maximum Load ÷ Cross-section Area
• Yield Strength (MPa) and Elongation (%)
• Young's Modulus (GPa) derived from the stress-strain curve
• All values are compared against the specified standard limits

Step J — Report Preparation

Our team compiles everything into a comprehensive test report — including the stress-strain graph, specimen photographs, all calculated values, and observations. The report is reviewed and signed off by our qualified testing personnel before release.

Step K — Result Delivered to You

Your final test report is issued in PDF and/or hard copy format, complete with:

• All measured and calculated parameters
• Clear pass/fail verdict against the applicable standard
• Certificate of testing with our ISO/IEC 17025 accreditation stamp
