CMZH Cable Marker Low Fire Hazard – EN45545-2 HL3 (60 x 12)

The CMZH PO cable marker is a polyolefin, with halogen-free, low toxicity, flame retardant properties. The compound is excluded from halogens and offers excellent fire safety characteristics combined with minimal smoke emission.

It is typically used in areas and applications where human life and extended fire safety properties are specified.

The CMZH material boasts 3 top-class railway normative, being one of the best printable heat shrinkable materials for the railway market.

Can be used in other industries also.

The markers are supplied as all-in-one constructions on a roll and optimized for thermal transfer printing.

Additional info:

Material: The ZH heat shrink is made of halogen-free, flame retardant, polyolefin extruded flat band with ideal printability properties for identification purposes. The compound of the tubing is excluded from halogens and offers excellent fire safety characteristics combined with minimal smoke emission. A low smoke density allows good visibility during a fire, increasing the ease of escape and saving lives. A very low smoke toxicity and the excellent result in the LOI.

Standard: EN45545-2 is a standard that describes the material requirements for different hazard levels - HL1 - HL-2 -HL3 in railway applications. The standard sets the flammability, smoke emissions and toxicity requirements for internal and external applications.

The **HL levels** in **EN45545-2** standard are the **hazard levels** that reflect the fire risk and the difficulty of evacuation in case of fire for different railway vehicles¹². The HL levels are based on the combination of **operational categories** and **vehicle design categories**¹²³.

The **operational categories** range from **1** (easiest to escape) to **4** (hardest to escape)³. The **vehicle design categories** are **N** (non-passenger trains), **A** (sleeping cars), **D** (double-deck trains) and **S** (single-deck trains)¹.

The HL levels are defined as follows¹³:

- **HL 1**: Applies to vehicles that operate on open tracks with easy access and low speed. Examples are freight trains, shunting locomotives and maintenance vehicles.
- **HL 2**: Applies to vehicles that operate on open tracks with easy access and high speed, or on closed tracks with easy access and low speed. Examples are regional trains, trams and metros.
- **HL 3**: Applies to vehicles that operate on closed tracks with difficult access and high speed, or on open tracks with difficult access and low speed. Examples are high-speed trains, underground trains and trains that operate in long tunnels.
