Non-Destructive Testing

Non-destructive testing uses the acoustic, optical, magnetic and electrical properties of the material to detect whether there are defects in the tested object and to obtain the size, location, nature and quantity of defects, while ensuring the integrity of the materials.

Testing Applications

Detect defects in the interior and surface of the materials.
Measure the geometric characteristics and dimensions of the materials
Determine the internal composition, structure, physical properties and state of the materials.

Test Services

Liquid Penetrant Testing

STEMart provides liquid penetrant testing for surface quality detection of non-porous materials (such as metal, plastic, glass, ceramic and steel parts).

Magnetic Particle Inspection

STEMart provides magnetic particle inspection service to help manufacturers to check defects and cracks on the surface of materials.

Eddy Current Testing

STEMart provides eddy current testing service to help manufacturers to detect surface and near-surface flaws in conductive materials.

Ultrasonic Testing

STEMart provides ultrasonic testing service to detect internal defects and to analyze the physical properties or microstructure of the materials.

Radiographic Testing

STEMart provides radiographic testing service for examination of the internal features of a product, to characterize materials properties, and to identify defects.

Hydrostatic Pressure Testing

STEMart provides hydrostatic pressure testing service to determine whether a pressure vessel involving the storage and transportation of fuel, chemicals, and other hazardous materials can safely hold the amount of pressure it's rated for.
