UnitedTest has built a diversified product matrix of test specimens, adaptable to the testing requirements of metals, plastics, rubber, composites, and other materials.
The core offerings cover three main types of tests:
1, Dumbbell-shaped tensile test specimens: Serving as the key carriers for material tensile performance testing, they strictly follow standards such as GB/T 528-2009 and GB/T 1040. The thickness deviation in the narrow section (within ±0.05mm) and test length accuracy are precisely controlled. They are compatible with various specifications like Type 1, Type 2, and Type 3. Whether for strength testing of rigid materials or toughness evaluation of flexible materials, they provide a stable and reliable specimen foundation.
2, Impact test specimens: Designed according to the ISO 8256:2023 international standard, optimized for rigid, flexible, and thin-walled materials. They accurately reflect the brittleness or toughness of materials under specific impact speeds and are suitable for impact resistance testing of plastics, metal forgings, and other materials. The preparation process is fully compatible with ISO 179 and ISO 180 series test requirements.
3, Torsion test specimens: Based on the ISO 18338:2021 standard, focused on room-temperature torsion performance testing of metal materials. Precision machining ensures specimen dimensional consistency, helping clients accurately obtain key indicators such as material torsional strength and torsional stiffness, providing data support for product design in fields like mechanical manufacturing and aerospace.
Additionally, UnitedTest can provide specimens for compression, bending, and various other test types, comprehensively covering all scenarios in scientific research, production quality inspection, and product certification.
Key Features
Compliance and adaptability are the core competencies of UnitedTest. All samples strictly adhere to the relevant standards of the International Organization for Standardization (ISO), including the latest versions of ISO 8256 (tensile impact), ISO 15461 (mechanical testing of metal forgings), ISO 18338 (torsion testing), and others, ensuring that test results are internationally recognized and comparable, helping customers smoothly pass various industry certifications and product inspections.
For special scenario requirements, UnitedTest offers customized drawing services: customers can provide detailed dimensions, material requirements, and test standards, and the technical team, drawing on years of industry experience, will optimize structural design and processing techniques to achieve full-process customization, from blank cutting, precision machining, to final product verification. Whether it is non-standard size dumbbell-shaped samples or complex structure impact test pieces, UnitedTest can precisely match customer needs, addressing challenges with special materials or personalized testing.
