CHEMISTRY AND ANTICORROSION SECTION

● Tests of paint and anti-corrosion coatings, among others, according to:

• PN-EN ISO 2808 - thickness by magnetic-inductive method (7B.2) on ferrous substrate, by eddy-current method (7C) on non-ferrous substrate and by wedge cut method (6B),
• PN-EN ISO 1519 - bend test (cylindrical mandrel),
• PN-EN ISO 6272-1 - rapid-deformation (impact resistance) tests,
• PN-EN ISO 1520 - cupping test,
• PN-EN ISO 15184 - determination of film hardness by pencil test,

• PN-EN ISO 1522 –  hardness of coatings (pendulum damping test),

• PN-EN ISO 2409, PN-EN ISO 16276-2 - determination of adhesion/cohesion (fracture strength) of a coating by cross-cut and X-cut test,
• ASTM D6578 - determination of graffiti resistance,
• PN-EN ISO 2812 parts 1 & 3 – determination of resistance to liquids by immersion and using an absorbent medium methods,

• PN-EN ISO 4628 parts 1, 2, 3, 4, 5, 6, 8 – evaluation of degradation of coatings (blistering, rusting, cracking, flaking, chalking, delamination and corrosion around a scribe),

• PN-EN ISO 4624 - adhesion of coatings (pull-off test for adhesion),

• methods developed by the Institute and other standardized methods.

● Tests of wooden elements of the railway line according to:

• PN-EN 13145+A1 (harmonised with the TSI INF),
• PN-D-95006,
• PN-D-95013,
• PN-D-95014,
• DIN 68811,
• and documents related to standards

●  Evaluation of consummables (for compliance with normative documents developed by the Institute, such as:

• cleaning agents (influence on train equipment)
• herbicides for weeding of the railway line (influence on infrastructure and effectiveness in weeding on railway tracks).
