This document defines the assessment of endurable longitudinal compressive forces (LCF) of a vehicle. The endurable longitudinal compressive forces is a parameter depending on the vehicle design. It is used to estimate the risk of derailment as a result of being subjected to these forces, under operating conditions.
NOTE 1   As operating conditions may vary in several aspects (infrastructure, train configurations etc.), this document defines uniform assessments of endurable longitudinal compressive force per vehicle in specific operating conditions. One of these endurable longitudinal compressive forces is derived from UIC 530-2, which is based on practical tests performed in ERRI-B12. Other endurable longitudinal compressive forces as the outcome of this document are central input parameters in the methodology of IRS 40421. IRS 40421 derives train and operational parameters from the outcome of EN 15839 which are vehicle parameters.
This document applies to the following types of vehicles:
—   single wagons;
—   permanently coupled units with side buffers and screw couplers between the vehicles;
—   permanently coupled units with diagonal buffers with screw couplers between the vehicles;
—   permanently coupled units with a bar coupler between the vehicles;
—   articulated units with three 2-axle bogies;
—   wagons with 3-axle bogies; low-floor wagons with eight or more axles (e.g. rolling road wagon);
—   vehicles with central couplers;
—   on-track machines (OTM) as defined in EN 14033-1.
NOTE 2   The document defines the acceptance process to be followed by vehicles that are operated in a way that high longitudinal compressive forces may occur in the trains due to their to their operational environment (e. g. train composition, braking regime, track layout). Therefore, vehicles among the previous list which are not subjected to high longitudinal compressive forces may not need to fulfil this document.
The following vehicles are not in the scope of this document:
—   articulated wagons with more than three 2-axle bogies;
—   locomotives and passenger rolling stocks;
—   vehicles that are only operated in passenger trains.
Acceptance criteria and test conditions as well as conditions for simulation and test dispensation are defined in this document.
This document applies principally to vehicles which operate without restrictions on standard gauge tracks in Europe (1 435 mm).
NOTE 3   The influence on railway systems using other gauges is not sufficiently understood to extend the scope of this document to gauges other than standard.
NOTE 4   For wagons with central couplers, a need for assessment of derailment risk due to Longitudinal Forces on other gauges (1 524 mm, 1 600 mm, 1 668 mm) has been expressed. The influence on railway systems using other gauges is not sufficiently understood. This document only introduces some notions to assess it independently from the gauge.

This document specifies a method to determine the free glycerol and residual mono-, di- and triglyceride contents in fatty acid methyl esters (FAME). The total glycerol content is then calculated from the obtained results.
Under the conditions described, the quantification limits are 0,001 % (m/m) for free glycerol, 0,10 % (m/m) for all glycerides (mono-, di- and tri-). This method is suitable for FAME prepared from rapeseed, sunflower, soybean, palm, animal oils and fats and mixture of them. It is not suitable for FAME produced from or containing coconut and palm kernel oils derivatives because of overlapping of different glyceride peaks.
NOTE 1   For the purposes of this document, the term "% (m/m)" is used to represent the mass fraction.
NOTE 2   Under the common EN 14105 GC conditions, squalene can coelute with alpha glycerol monostearate. If the presence of squalene is suspected, EN 17057 can be used to discriminate between squalene and glycerol monostearate.

This part of EN 1366 specifies a test method for determining the fire resistance of smoke extraction ducts that are used for single compartment applications only. In such applications, the smoke extraction system is only intended to function up to flashover (typically 600 °C).
This method of test is only suitable for ducts constructed from non-combustible materials (euro class A1 and A2-s1, d0).
It is applicable only to four sided and circular ducts. One-, two- and three-sided ducts are not covered. This standard is applicable only for the standard sizes or smaller as described.
This test method of part 9 is applicable only to smoke extraction ducts that do not pass into other fire compartments. For smoke extraction ducts that pass into other compartments, the method of test described in EN 1366-8 is used.
The smoke extraction duct is part of the smoke extraction system which also includes smoke control dampers and smoke extract fans.

This document specifies a test method for determining the fire resistance of smoke extraction ducts. It is applicable only to smoke extraction ducts that pass through another fire compartment from the fire compartment to be extracted in case of fire. It represents fire exposure of a fully developed fire.
This method of test is only applicable to fire resistant ventilation ducts (same construction) with the following classification according to EN 13501-3:
-   fire from inside and outside i ↔ o;
-   applicable to a pressure difference up to 500 Pa;
NOTE 1   It is assumed that the duct A test(s) in accordance with EN 1366-1 has been performed with an under-pressure of minimum 500 Pa.
-   with integrity (E) and insulation (I) criteria equal to or higher than the intended classification for the smoke extraction duct.
For the purposes of the test described in this document, the duct is referred to as duct C.
This test method has been designed to cover both vertical and horizontal smoke extraction ducts. A vertical system need not be evaluated to this method provided that:
-   both horizontal (ho) and vertical (ve) classification according to EN 13501-3 has been obtained for the ventilation duct, and
-   it has been tested in a horizontal orientation to this method.
If the ventilation duct in practice is only used for vertical applications in smoke extraction systems, only vertical (ve) classification is bound to be used and tested in a vertical orientation to this method according to EN 13501-3.
This test method is suitable for ducts constructed from non-combustible materials (Euroclass A1 and A2 according to EN 13501-1).
NOTE 2   Reaction with components of the duct can reduce the oxygen concentration and lead to misinterpretation of the calculated leakage rate.
This standard applies to four sided ducts only (with fire exposure on all four sides). Ducts that utilize elements of construction for one, two or three sides are not covered. An alternative test method for one, two and three sided ducts will be developed separately.
