Qualified Adhesives for FST Hazard Protection

EN 45545-2:2013 Standard for fire protection on railway vehicles

Adhesives Standards Hazard Level Requirements

SG300 EN45545-2 HL3* R1

SG230 EN45545-2 HL3 R1

SG800 EN45545-2 HL3 R1

*HL3 = lowest hazard rating for R1 Requirements (Good for rail interior components)
