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.

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.

Standard
ASTM D695: Standard Test Method for Compressive Properties of Rigid Plastics
ASTM D695 test covers the determination of the mechanical properties of unreinforced and reinforced rigid plastics, including high-modulus composites, when loaded in compression at relatively low uniform rates of straining or loading. Test specimens of standard shape are employed. This procedure is applicable for a composite modulus up to and including 41,370 MPa (6,000,000 psi). It is technically equivalent to ISO 604 Plastics‑Determination of Compressive Properties. This test applies end‑loading compression on standard‑geometry specimens under controlled environmental and displacement‑rate conditions, delivering compressive strength, yield strength, offset yield strength, compressive elastic modulus, and compressive deformation data.
ASTM D3039 Standard Test Method for Tensile Properties of Polymer Matrix Composite Materials
ASTM D3039 defines a unified procedure to measure the in-plane tensile properties of high-modulus fiber-reinforced polymer matrix composites (PMC). It applies exclusively to continuous or discontinuous fiber-reinforced laminates that are balanced and symmetric with respect to the test direction.
ISO 15024 Fibre-reinforced plastic composites. Determination of mode I interlaminar fracture toughness, GIC, for unidirectionally reinforced materials
ISO 15024 specifies the double‑cantilever‑beam (DCB) test for measuring Mode‑I interlaminar fracture toughness GIC (critical energy release rate, unit: J/m²), which quantifies material resistance to opening‑mode delamination crack initiation and growth between composite plies.
ASTM D5528 Standard Test Method for Mode I Interlaminar Fracture Toughness of Unidirectional Fiber-Reinforced Polymer Matrix Composites
ASTM D5528 is standard test method for Mode‑I (opening‑mode) interlaminar fracture toughness GIc of unidirectional fiber‑reinforced polymer‑matrix composite laminates, using Double Cantilever Beam (DCB) specimens. It quantifies the critical strain‑energy release rate for delamination initiation and growth between composite plies.
ASTM D5766 Standard Test Method for Open Hole Tensile Strength of Polymer Matrix Composite Laminates
ASTM D5766 for measuring the open‑hole (notched) tensile strength (OHT) of a multi‑directional fiber‑reinforced polymer composite laminate — essentially a ASTM D3039 tensile coupon with a precision‑machined hole in the middle, pulled to failure in uniaxial tension.It quantifies the notch effect from a central through‑hole, simulating fastener cut‑outs in real composite structures.
