Material testing standards define how a specimen must be prepared, loaded and measured so that results are consistent, reproducible and comparable across laboratories, suppliers and countries. When purchasing a material testing machine, understanding the standard that governs your product is critical: different standards can specify different specimen shapes, test speeds, measurement methods and reporting requirements. Choosing a machine that can be configured to your standard ensures you produce valid, defensible test data.
The sections below introduce the major standards families and link to the CHENJI machines most often configured to each of them, so you can go from your standard to the right testing solution.
ISO – International Organization for Standardization
The International Organization for Standardization develops globally recognised testing methods used across industries worldwide. ISO standards are widely adopted in international trade and export markets, making them a common requirement for manufacturers selling across borders. Typical ISO methods include ISO 6892-1 for tensile testing of metals, ISO 7500-1 for verification of the force-measuring system, ISO 1133 for melt flow rate of thermoplastics and ISO 1099 for axial fatigue testing.
Machines commonly configured to ISO include the WAW-2000D hydraulic universal testing machine, the WDW electronic universal testing machine and the CXNR-400D melt flow rate meter.
ASTM – American Society for Testing and Materials
ASTM produces standards heavily used in North America and in many export-oriented industries such as metals, plastics, rubber and construction. ASTM test methods are detailed and widely referenced in procurement specifications. Common methods include ASTM E8 for tension testing of metallic materials, ASTM E4 for force verification of testing machines and ASTM D1238 for melt flow rate of thermoplastics.
CHENJI machines configured to ASTM include the WAW 1000 kN / 2000 kN computer controlled hydraulic UTM and the WAW-300 kN hydraulic universal testing machine.
DIN – German Institute for Standardization
DIN standards are characteristic of Europe’s engineering tradition, particularly strong in automotive, machinery and precision manufacturing. DIN methods often emphasise exacting procedural and dimensional control, and they are frequently specified alongside EN (European) standards for products placed on the European market. A universal testing machine with a wide, adjustable test-speed range and interchangeable grips is usually the most flexible starting point for DIN work.
For European customers CHENJI supplies electronic universal testing machines and hydraulic universal testing machines able to run DIN, EN and ISO methods on one platform.
GB – Chinese National Standards
Chinese National Standards govern domestic manufacturing and quality inspection in China. GB methods are essential for products manufactured for or sold within the Chinese market and are increasingly aligned with international practice. Common GB methods include GB/T 228 for tensile testing of metals, GB/T 3682 for melt flow rate and GB/T 4340 for Vickers hardness.
Machines configured to GB include the CXNR-400D melt flow rate meter (GB/T 3682) and the HV Vickers hardness tester.
EN – European Standards
European Standards harmonise testing requirements across EU member states. EN methods are often mandatory for products placed on the European market and frequently reference or align with ISO methodology, so a machine that can be configured to ISO is normally also suitable for the corresponding EN method. Buyers should confirm the exact EN part and the specimen geometry with the machine supplier before ordering.
CHENJI electronic and hydraulic universal testing machines are configured to the ISO methods on which most EN methods are based, and the torsion testing range covers the shear methods used for wire and springs.
JIS – Japanese Industrial Standards
Japanese Industrial Standards drive quality in Japan’s automotive, electronics, steel and machinery sectors. JIS is noted for its precision and is commonly required for components exported to Japan or produced under Japanese specifications. JIS tensile and hardness methods closely parallel the ISO methods, so the same universal testing machine and hardness tester usually serve both.
For JIS customers CHENJI supplies hardness testers and fatigue testing machines as well as universal testing machines configured to the JIS test method.
How to Choose a Machine for Your Standard
The right testing machine is the one that matches the requirements of your specific standard – and that means more than just load capacity. Your machine should be able to achieve the required test speed and force accuracy, accept the specimen dimensions defined by your standard, and report results in the format your standard demands. A universal testing machine with a wide, adjustable test-speed range and interchangeable grips is usually the most flexible starting point, letting you run multiple standards on a single platform.
At CHENJI we configure our machines to your specified testing standard. Whether you need a universal testing machine, a hardness tester, a fatigue or torsion machine, or specialised equipment for plastic and fastener testing, we can match the configuration to the standard that governs your product. Tell us your standard and your specimen, and we will recommend the right machine and accessories.
Frequently Asked Questions
What is the difference between ISO, ASTM, DIN and GB standards?
They are issued by different standards bodies (international, American, German and Chinese) and can specify different specimen shapes, test speeds and reporting requirements; a machine is configured to the standard that governs the product.
Does a machine configured to ISO also test to EN?
Usually yes, because most EN test methods reference or align with ISO methodology, but the exact EN part and specimen geometry should always be confirmed before ordering.
Which standards can CHENJI machines test to?
CHENJI machines are configured to ISO, ASTM, DIN, GB, EN and JIS methods, for example ISO 6892-1 and ASTM E8 for metal tensile testing and ISO 1133 and ASTM D1238 for melt flow rate.
How do I choose the right machine for my standard?
Match the machine’s test-speed range, force accuracy and specimen capacity to your standard, and choose a machine with interchangeable grips so it can run several methods; our engineers will confirm the configuration.
Can you supply the machine already configured to my standard?
Yes. Tell us your standard and specimen and CHENJI configures the machine, fixtures and software to that method before delivery.
