ISO/IEC 17025 Accredited, KOLAS KT921
Accredited materials testing, KOLAS KT921
Our scope of accreditation under the Korea Laboratory Accreditation Scheme (KOLAS) covers 25 test items, and we perform demanding tests in-house, including thermomechanical fatigue (TMF), fracture toughness and fatigue crack growth rate (FCGR) testing. KOLAS is a signatory to the ILAC Mutual Recognition Arrangement (ILAC MRA), which facilitates the acceptance of accredited test reports in other signatory economies.
Accreditation
KOLAS-accredited testing laboratory (Accreditation No. KT921)
Accredited tests: tensile testing at room, elevated and low temperatures; creep testing; low-cycle fatigue (LCF) and high-cycle fatigue (HCF) testing; TMF testing; KIc and JIc fracture toughness testing; FCGR testing; Charpy impact testing at room, elevated and low temperatures; and Vickers and Rockwell hardness testing. This capability is core infrastructure for ensuring reliability in power generation, aerospace and defense.

5-Step Process
Mechanical Testing
Six mechanical test types
From tensile testing to instrumented indentation, we quantify the mechanical properties of materials in accordance with recognized test procedures.
UTS · YS · Elongation
Quantifies tensile behavior at room and elevated temperatures, including yielding and fracture behavior.
Larson–Miller parameter (LMP) · Robinson's life-fraction rule
Evaluates deformation and time to rupture under sustained stress at elevated temperatures.
S-N · LCF · HCF · TMF
Evaluates fatigue life under cyclic loading, including high-temperature thermomechanical fatigue (TMF) testing.
KIc · JIc · Master Curve
Toughness evaluation using C(T) and SE(B) specimens, plus fatigue crack growth rate (FCGR, da/dN) testing.
Absorbed energy at low and elevated temperatures
Analyzes the ductile-to-brittle transition temperature (DBTT) and toughness variation with temperature.
IIT (instrumented indentation)
Vickers and Rockwell hardness testing, plus estimation of mechanical properties by instrumented indentation testing (IIT).
Materials Database
High-temperature materials database — MMPDS
Following MMPDS (Metallic Materials Properties Development and Standardization) data development guidelines, we have built a materials database covering 10 or more superalloys for gas turbines. We provide reliability validation data to Hanwha Aerospace, Doosan Enerbility and the aerospace and defense sectors.

Hydrogen Embrittlement Evaluation
Hydrogen embrittlement testing infrastructure
Using an in-house-built autoclave (max. pressure 172 bar / 2,500 psi; max. temperature 340 °C; flow rate 7 mL/min, up to 10 mL/min), we prepare specimens by electrochemical hydrogen charging at high temperature and pressure. Hydrogen effects are then evaluated through slow strain rate testing (SSRT), creep, FCGR and Charpy tests, together with fracture surface analysis by scanning electron microscopy (SEM).
