Testing & Analysis

PSM Technical Centers are equipped with a wide range of test equipment to allow the performance of our parts to be tested against customer requirements.
Commonly requested tests include:

Sample Preparation For Hardness Testing And Microstructure Analysis
Prior to testing the hardness of fasteners and analyzing the material structure, samples have to be cut , mounted and polished. PSM uses a range of equipment to ensure the quality of prepared sample and accuracy of results obtained.
Hardness Testing
PSM has a range of hardness test equipment, allowing customers supplied components to be tested to determine the most suitable fasteners for the application.
Fasteners case depth, surface hardness and core hardness can also be checked using a micro-hardness test machine.
Material Microstructure Analysis
Many Sheet Metal Fasteners are hardened to ensure they correctly "clinch" when press fitted into the host sheet metal component. In addition to hardness testing, PSM can analyze the grain structure to ensure the heat treatment process has been correctly controlled.
Plating Thickness Measurement And Element Analysis
Most fasteners are plated to prevent corrosion, PSM uses "sate of the art" X-ray fluorescence (XRF) measuring equipment to determine the plating thickness and for element analysis.
ROHS Analysis
To ensure conformance to RoHS standards, PSM has its own "in-house" test capability. The presence of restricted substances such as Lead (Pb), Cadmium (Cd), Mercury (Hg) and Hexavalent chromium (Cr6+) can be detected and measured in ppm.
Salt Spray Testing
Salt spray testing is a standardized test method used to measure the corrosion resistance of coated samples. PSM has "in-house" equipment allowing NSS, ASS & CASS to be tested to ISO and ASTM B standards.
