BASF Engineering Plastics Certified to EN 45545 Railway Standard

Key highlights
  • BASF Ultramid and Ultradur grades hold EN 45545 classifications for railway electrical/electronic applications across various R groups and HL1–HL3.
  • Flame-retardant systems cited: FR30, FR40, FR72 based on nitrogen/phosphorus intumescent chemistries and magnesium hydroxide as a halogen-free alternative.
  • Formulations intentionally exclude added chlorine and bromine to reduce corrosive smoke gas risk.
  • EN 45545 certification is color-independent and covers defined minimum and maximum wall thicknesses to support design freedom.

EN 45545 certification

BASF Ultramid and Ultradur engineering‑plastic grades are classified to the European railway fire‑safety standard EN 45545 for electrical & electronic (E&E) components; the standard aims to reduce ignition likelihood, slow flame spread and limit smoke and toxic gas emissions to allow safe evacuation. Certified grades cover various application groups and Hazard Levels (HL1–HL3), with specific mentions of application groups such as R22, R24, R25 and R34 and reference to R1–R26 categories.

Flame‑retardant chemistry

Certification uses flame‑retardant systems FR30, FR40 and FR72 based on nitrogen/phosphorus intumescent systems and magnesium hydroxide as a halogen‑free alternative; formulations intentionally exclude added chlorine and bromine to reduce corrosive smoke gas risk.

Design and material details

EN 45545 classification reports are available for named Ultramid and Ultradur grades: Ultramid A3UG5, A3U42G6, B3UG4, B3UGM210, C3U, TKR4340G6, Advanced N3U41G6; Ultradur B4450G5 and B4441G5. Certification is color‑independent and covers defined minimum and maximum wall thicknesses, providing design freedom within tested ranges.
