Information on the most widely used ASTM standards within the materials testing industry
Model: WDW-100Y/ WDW-200Y / WDW-300Y (100 ~300KN)
Universal Material Testing Machine (UTM) is a sophisticated instrument designed to evaluate mechanical properties of various materials under controlled loading conditions. It's called "universal" because it performs multiple types of tests—tensile, compression, bending, shear, peel, and tear—on a wide range of materials including metals, plastics, composites, rubbers, and textiles .
UTMs serve as the cornerstone of quality control, research and development, and material certification across industries. They provide accurate data for product design, safety assessment, and compliance with international standards.
Floor type two columns WDW Series Computer Control Electronic Universal Testing Machine made by UNITEDTEST range from 100KN to 300KN load capacity, matched with UNITEDTEST design and produced various test fixture, like peel, flexure, puncture, tear, pneumatic grip, belt tension etc., this UTM can be used to almost all materials include but not limited to steel rod, rubber, steel wire, plastic, seat belt, textile, wood, panel etc., mechanical performance inspection.

General introduction
UnitedTest Dual Column Floor Type Testing Systems are universal, static tensile testing systems that perform tensile and compression testing; and also perform shear, flexure, peel, tear, cyclic, and bend tests. This series are engineered for precision, built for durability, and offer the flexibility for changing requirements.They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.
Dual column systems are multi-purpose instruments that are commonly used for plastics, metals, rubber materials, automotive components, composites, and non-ambient temperature applications.
Load weighing system meets or exceeds the requirements of the following standards: ASTM E4, EN10002-2, BS 1610, DIN 51221, ISO 7500-1.
Working Principle:
UTMs operate through a systematic process:
1, Force Application: A precisely controlled drive system applies tensile or compressive force to a specimen
2, Deformation Measurement: High-precision sensors record the specimen's response
3, Data Analysis: A computer system processes data to calculate key mechanical properties
Drive Systems:
Electronic UTMs: Use servo motors coupled with precision ball screws to generate motion. This provides clean, quiet operation with excellent control from 0.001mm/min to 500mm/min (max. to 2000mm/min)
Control Philosophy:
Modern UTMs employ closed-loop control systems that continuously monitor and adjust force, displacement, or strain during testing. This ensures constant test parameters regardless of material behavior.

PC control system, with advantage of high integration, reliable performance, easy adjusment etc. can real time collect test data, on-time display test curve, test data file can be saved as ACCESS and SQL server, convenient for customer's data resource storage.
Automatically generate the testing report; the testing report can be displayed and printed, also it can be export in Excel/Access Format. Also, the user can edit the report format as requirement in report template;
Result recall function: after the test and saved, customer can open the test data and re-analysis at any time.
Results compare: observe several curve at same time, can fold curve or portion enlarge to analyze and compare sample characters.
Load~Time, Load~displacement, Displacement~time etc. curve smoothly switch, display test data, save, analysis and print.

Frequently Asked Questions
Dual space and Single space difference
UnitedTest offer two kinds frame structure for the test space, dual test space and single test space.
| ![]() |
Advantage of dual space structure: | Advantage of dual space structure: For some user, only or frequently to do tensile test, the tensile grips at lower place, easy for operation to install the specimen. (For some tester like 200KN and 300KN, frame is higher like 2600mm, the tensile grips at upper place is not very suitable to clamping the specimen) |
