Railway Smoke Density & Visibility Testing Equipment – EN 45545-2 | KDM Global

Overview:

KDM Global is a trusted manufacturer and exporter of Railway Smoke Density & Visibility Testing Equipment designed to comply with EN 45545-2 and ISO 5659-2 standards. These high-precision systems are engineered to assess the smoke generation and visibility reduction characteristics of materials used in railway interiors during fire incidents.

Our equipment helps metro rail authorities, coach builders, OEMs, and accredited labs to test and certify materials for safe use in railway environments by simulating real fire conditions and measuring how smoke impacts visibility and evacuation.

What Is Smoke Density & Visibility Testing?

Smoke density testing evaluates the specific optical density (Ds) of smoke produced when a material burns under controlled conditions. Reduced visibility due to smoke is a major hazard in trains and metros during fire accidents. EN 45545-2 mandates that materials used in railway interiors must not generate excessive smoke that impairs visibility and evacuation.

Testing smoke density ensures that materials meet Hazard Levels HL1, HL2, HL3, depending on their location and application in a railway coach.

Standards Supported:

• EN 45545-2 Requirement for Smoke Opacity

• ISO 5659-2: Plastics — Smoke Generation in a Closed Chamber

• ASTM E662 (Optional calibration standard)

• ISO 5658 & ISO 9239-1 (For extended compliance)
