Railway applications - Braking - Empty-loaded changeover devices
This document is applicable to empty-loaded changeover devices. The purpose of such devices is the generation of a load-related signal which causes the brake performance to be adjusted to the current vehicle mass.
The manually operated empty-loaded changeover devices change their output signal according to the position of the handles which together with the associated changeover plates serve as interfaces. The changeover plates read the required information for the operation of the empty-loaded changeover devices, i.e. brake weights for each position and the relevant changeover mass of the vehicle.
Automatic empty-loaded changeover devices sense a certain load threshold of the vehicle to automatically adjust the output signal when the mass of a vehicle reaches a defined value. This threshold is the changeover mass. Below this mass the vehicle’s brake system provides a reduced brake force. For the changeover mass or more the high brake force applies.
This document specifies the requirements for the design, testing and quality assurance of empty-loaded changeover devices.

Gas safety shut-off devices for inlet pressure up to 10 MPa (100 bar)
This document specifies constructional, functional, testing marking and sizing requirements and documentation of gas safety shut-off devices:
- for inlet pressures up to 100 bar and nominal diameters up to DN 400;
- for an operating temperature range from -20 °C to +60 °C;
which operate with fuel gases of the 1st and 2nd family as defined in EN 437, used in the pressure regulating stations in accordance with EN 12186 or EN 12279, in transmission and distribution networks and also in commercial and industrial installations.
"Gas safety shut-off devices" will hereafter be called "SSDs" except in titles.
For standard safety shut-off devices when used in pressure regulating stations complying with EN 12186 or EN 12279, Annex ZA lists all applicable Essential Safety Requirements of Directive 2014/68/EU (PED).
This document considers the following temperature classes/types of SSDs:
- temperature class 1: operating temperature range from -10 °C to 60 °C;
- temperature class 2: operating temperature range from -20 °C to 60 °C;
- functional class A: SSDs that close when damage to the pressure

This European Standard specifies constructional, functional, testing, marking, sizing and documentation requirements of gas pressure regulators:
- for inlet pressures up to 100 bar and nominal diameters up to DN 400;
- for an operating temperature range from - 20 °C to +60 °C,
which operate with fuel gases of the 1st and 2nd family as defined in EN 437:2003+A1:2009, used in the pressure regulating stations in accordance with EN 12186 or EN 12279, in transmission and distribution networks and also in commercial and industrial installations.
"Gas pressure regulators" hereafter will be called "regulators" except in the titles.
For standard regulators when used in pressure regulating stations complying with EN 12186 or EN 12279, the Annex ZA lists all applicable essential safety requirements of the European legislation on pressure equipment except external and internal corrosion resistance for applications in corrosive environment.

Fire resistance tests for service installations - Part 10: Smoke control dampers
This document specifies test methods for smoke control dampers to assess their performance under elevated temperature or fire conditions, as well as at ambient temperatures.
Smoke control damper tests are used to confirm that the furnace testing requirements of EN 12101-8 are met and EN 12101-8 is for consideration before carrying out these tests.
Smoke control dampers tested to this document are expected to be classified using EN 13501-4 and this document is expected to be considered before carrying out these tests.
NOTE Some smoke control dampers to be tested might require testing following the information given in EN 1366-2 and this needs consideration before carrying out testing.
This document is expected to be read in conjunction with EN 12101-8, EN 13501-4, EN 1366-2 and EN 1363-1, the latter giving further details for fire resistance testing.
For installation details, the requirements for smoke extraction ducts are for consideration and these are defined in EN 1366-8 and EN 1366-9.
