Testing materials

Examination of chemical composition for metal alloys with Optical Emission Spectrometer that provides a chemical analysis of the material.

Namely, contents of the different elements making up the specimen.

This examination can also be carried out by melting small parts in a vacuum furnace.

Non-destructive examination (NDE) without need to cut the specimen

The object of the examination is to investigate the microstructure of the material and subsequently draw conclusions regarding its properties.

This examination can be carried out in the field (at the customer site) and not in the laboratory.

Acceptance tests for unassembled printed circuits (PCB) according to IPC standards

Section tests for quality of soldering of components for printed circuits

Investigation of an existing product to determine its chemical composition and its production process including its mechanical properties, special processes that it underwent, coating, thermal treatment etc.

Tests in salt spray fog chamber according to ASTM B117.

Tests in humidity chamber (up to 100% relative humidity)

Intergranular corrosion tests for stainless steel.

Pitting corrosion ‎tests for stainless steel.

Stress corrosion ‎test for brass.

Testing for zinc loss in brass.

Macroscopic tests Preparation of macroscopic specimens for weld tests According to ASME IX, DIN EN ISO 15614 and AWS standards.

Preparation of metallographic specimens according to ASTM E3 for examination of microstructure, coatings, intergranular corrosion and pitting, grain size, carburization/decarburization etc.

Testing of tensile specimens according to ASTM E8 for tensile and yield strength, elongation and reduction of area of the section.

Testing of fasteners for tensile and shear strength.

Hardness testing according to ASTM E18 by Rockwell method A, B, C, 15T, 30N.

Micro hardness testing according to ASTM E384 and ASTM E92 by Vickers and Knoop method.

Bend tests according to ISO 5173 and ASME IX standards and customers' standards.

Impact tests according to ASTM E23 at a temperature of 25°C (room temperature) to -45°C.
