Railway applications - Fire protection on railway vehicles - Part 3: Fire resistance requirements for fire barriers
SIST EN 45545-3:2024

This document specifies the fire resistance requirements and testing methods for fire barriers for railway vehicles.
The objective of the measures and requirements, specified in this document, is to protect passengers and staff in railway vehicles in the event of a developing fire on board.
Use of a Fire Containment and Control System, where permitted as an alternative to a fire barrier, is not in the scope of this document. It is not within the scope of this document to describe measures that ensure the preservation of the railway vehicles in the event of a fire.

SIST EN 45545-4:2024

This document specifies fire safety requirements for railway vehicle design to cover the objectives specified in EN 45545-1:2013.
The measures and requirements specified in this document 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 document to describe measures which ensure the preservation of the railway vehicles in the event of a fire.

Railway applications - General terms and definitions
SIST EN 17343:2023

This document provides terms and definitions for rail networks and rail vehicles guided by track and wheels, both made of steel and/or other materials.
This includes heavy rail and urban rail systems.
This document is applicable as a reference for future European Standards and the revision of existing standards and represents a set of general technical terms and definitions.
This document does not apply to specific applications such as:
-   track construction and maintenance machines not travelling on rails;
-   road-rail machines when not travelling on rails;
-   magnetic levitation transport networks and vehicles;
-   guided busways and guided busses;
-   non-public rail networks and vehicles, e.g. mine rail systems;
-   rail networks and vehicles exclusively for leisure, historical and tourist purposes, e.g. mountain-, field-, park-, cable rail systems, funiculars and theme park rides;
-   trolley busses.
Not in the scope are terms and definitions related to:
-   control command and signalling,
-   operation,
-   geographical aspects.

EN 15654-1:2018+A1:2023(Main)
Railway applications - Measurement of vertical forces on wheels and wheelsets - Part 1: On-track measurement sites for vehicles in service
SIST EN 15654-1:2018+A1:2023

The scope of this European Standard is restricted to the measurement of vertical wheel forces and calculation of derived quantities on vehicles in service. Measurements of a train in motion are used to estimate the static forces.
Derived quantities can be:
-   axle loads;
-   side to side load differences of a wheel set, bogie, vehicle;
-   overall mass of vehicle or train set;
-   mean axle load of a vehicle or train set.
This standard is not concerned with the evaluation of:
-   dynamic wheel force or derived quantities;
-   wheel condition (i.e. shape, profile, flats);
-   lateral wheel force;
-   combination of lateral and vertical wheel forces.
The standard defines accuracy classes for measurements to be made at any speed greater than 5 km/h within the calibrated range, which may be up to line speed.
The aim of this standard is to obtain measurement results that give representative values for the distribution of vertical wheel forces of a running vehicle, which under ideal conditions will be similar to those that can be obtained from a standing vehicle.
This standard does not impose any restrictions on the types of vehicles that can be monitored, or on which networks or lines the measuring system can be installed.
The standard lays down minimum technical requirements and the metrological characteristics of a system for measuring and evaluating a range of vehicle loading parameters. Also defined are accuracy classes for the parameters measured and the procedure for verifying the calibration.
The measuring system proposed in this standard should not be considered as safety critical. If the measuring system is connected to a train traffic command and control system then requirements that are not part of this standard may apply.
Measuring systems complying with this standard have the potential to enhance safety in the railway sector. However, the current operating and maintenance procedures rather than this standard are mandatory for ensuring safety levels in European rail networks.

Railway applications - Braking - Distributor valves and distributor-isolating devices
SIST EN 15355:2019+A1:2023

This document applies to distributor valves and distributor-isolating devices.
The distributor valves contained in this document are of graduable release type. Direct release types are not included.
Functionally they are regarded as not containing relay valves of any type, even if the relay valves are physically an integral part of the distributor valves.

This document specifies the requirements for the design, testing and quality assurance of distributor valves and distributor-isolating devices.
The distributor valve and distributor-isolating device are intended to be part of a brake system mounted in a vehicle with maximum length of 31 m and maximum brake pipe volume of 25 l taking into consideration brake pipe inner diameters between 25 mm and 32 mm.
