Advanced Indentation System

Instrumented Indentation Tester

1

 

Instrumented Indentation Tester (Non-Destructive

Test) is an All-in-one testing equipment for evaluating

mechanical properties (yield strength, tensile strength,

elasticity modulus, Strain hardening index) in Non-

Destructive way called Instrumented Indentation

Technique. When it was first developed, it has been

called different names such as automated indentation

tester, instrumented indentation tester (Non Destructive

Test) and portable Indentation tester, but for external

activities and promotion, we now use integrated name of

“Instrumented Indentation Tester (Non Destructive

Test)”.

Instrumented Indentation Tester (Non-Destructive

Test) is composed and classified as evaluating

properties and case, and the model name is “AIS”. “AIS” is

stand for Advanced Indentation System which is

addressing integrated instrumented indentation tester

(Non Destructive Test), and we have named or

numbered models as its features and evaluating

properties. (eg. AIS2000(now, AIS2100): Tensile

properties evaluation, AIS3000: residual stress

measuring model, etc)

Instrumented Indentation Tester (Non-Destructive

Test) continually measures indentation depth depend

on the indentation load to testing material, and obtains

indentation load displacement curve. Obtained data is

automatically transferred to computer with wire or

wireless. Based on this, it is equipment that allows user

to analyze the material properties and prepare a report

by clicking simplified program. As it is published as KS

B0950, B0951, ISO/TR 29381, KEPIC code MDF A370 and

ASME Code case 2703, the technology has been

recognized.

Main Usage

Receiving Test
 

It is possible to check quality of materials, whether the materials are suitable for basic standard(CMTR or Mill sheet) or not or it’s possible to check the quality or defective product through the materials of structure under construction is screened

Stability assessment
 

Securing integrity or degradation evaluation of structure by monitoring periodic properties transformation of the structure operating in industry

Reliability assessment 
for welding part

Coming up with an effective counterplan or integrity assessment of industrial facilities or welded structures

Failure analysis
 

Accident investigation through root cause analysis when a safety accident happens caused by destruction or deformation of the structures
