This Part of EN 438 applies to laminates less than 2 mm thick produced by using an high pressure process, normally intended for bonding to supporting substrates to produce HPL composite panels and establishes a classification system for high-pressure decorative laminates according to their performance and main recommended fields of application, including materials with special characteristics, for example formability or defined reaction to fire. This Part of EN 438 also specifies requirements for the properties of the various types of laminates covered by this classification system.
This Part of EN 438 specifies performance requirements for two types of Compact laminate of thickness 2 mm or greater intended for interior use. High-pressure decorative Compact laminates are characterised by their aesthetic qualities, strength, durability and functional performance. Compact HPL sheets are available in a wide variety of colours, patterns and surface finishes; they are extremely strong, and resistant to wear, impact, scratching, moisture, heat and staining; and possess good hygienic and anti-static properties, being easy to clean and maintain. EN 438-2 specifies the methods of test relevant to this part of EN 438.
This part specifies fire safety requirements for railway vehicle design to cover the objectives defined in EN 45545-1. The measures and requirements specified in this part of EN 45545 aim to protect passengers and staff in railway vehicles in the event of a fire on board by minimizing the risk of a fire starting, delaying the fire development and controlling the spread of fire products through the railway vehicle, thus aiding evacuation. It is not within the scope of this standard to describe measures which ensure the preservation of the railway vehicles in the event of a fire.
This part specifies the reaction to fire performance requirements for materials and products used on railway vehicles as defined in FprEN 45545-1.The operation and design categories defined in FprEN 45545-1 are used to establish hazard levels that are use
