Chemical analysis - qualitative and quantitative (composition, impurities, material grades referring to industry standards)
Mechanical testing (tensile testing e.g. elongation, upper yield strength, lower yield strength, conventional yield strength)
Hardness (Vickers, Brinnel, Rockwell, Shore)
Roughness analysis
Metallography (microstructure, decarburizatation, grain size, non-metallic impurities
Charpy impact tests
Corrosion resistance: salt fog/dry/humidity, salt spray (NSS, AASS, CASS), artificial atmospheric conditions etc.
Resistance to liquids (generally protective coatings, paints and varnishes)
Paints and varnishes: specific tests like adhesion with knife on edge, cupping test, cross-cut test, impact resistance, film thickness and many others
Fatigue testing
Methods specific to polymers and parts made of plastics including differential scanning calorimetry, FTIR
Determination of colour: colour analysis, RAL reference etc.
Cone penetration and dropping point (lubrication greases)
- Surface testing – Scanning Electron Microscopy (SEM)
Many other standard and non-standard methods
