3 Terms and Definitions
For the purposes of this Standard, the following terms and definitions shall apply.
3.1 Toilet System
Equipment that is to receive and store the toilet sewage in a running railway passenger
car or multiple unit to realize sewage collection.
3.2 Flush Components
Components that provide flushing water for toilets, usually including a water booster, a
flush valve, etc., and at least a flush valve.
3.3 Vacuum Components
Components that generate and monitor the vacuum in a vacuum toilet system.
3.4 Sewage Tank Valid Volume
The volume that a sewage tank sounds an alarm at its set maximum level.
3.5 Intermediate Tank
A transitional tank in a toilet system that is served to receive and store toile sewage
temporarily and then discharge the sewage into a sewage tank.
3.6 Emptying Device
The general term of joints that are fixed on a sewage tank to empty and wash the sewage
tank.
5.1.8.1 The toilet system shall on no condition affect the safety of power supplies, water
sources, and compressed air sources.
5.1.8.2 Parts and components shall conform to the train safety requirements, Where,
a) generally, current-carrying cables shall use low smoke halogen-free cables; and the
electric heating tube cables shall employ the cables resistant to high temperatures.
b) when tested on non-metal material properties and wires and cables under the
requirements of flame-retardant properties like oxygen indices, 45˚-angle burning,
and smoke density, a passenger car’s toilet systems shall have fire behaviors to
conform to the provisions in TB/T 3138-2006; when, if fire-protection rating is
required, tested under the requirements of fire behaviors like flammability rating,
smoke release levels, dripping levels, smoke toxicity, etc., based on the different
places where materials and components are installed and used, the toilet systems
of passenger cars and multiple units shall have their fire behaviors to conform to the
provisions in DIN 5510-2.2009; any specific user requirement shall be agreed upon
between both parties.
c) the requirements for sewage tanks to carry loads shall conform to UIC 566 or EN
12663.
d) the pressure-resistance requirements for the components bearing atmospheric or
hydraulic pressure shall conform to the specific technical requirements of each
component.
5.1.8.3 The electric heating system shall be furnished with short-circuit protection, ground
protection, and ground protection signs; heating with electric heating tubes and electric
blankets shall be provided with over-temperature protection devices.
5.1.8.4 For the toilet system whose drain valve can be directly seen from the toilet
entrance, it is appropriate to provide a warning sign in the toilet to prevent personal injury
because of putting hands in the toilet system by mistake.
5.1.9 Surface Treatment
For the under-car parts adopting plastic spraying or painting, the adhesive force of the
paint film shall fulfil the Grade 2 requirement set forth in GB/T 9286-1998.
5.2 Toilet System
5.2.1 The appearance and size of a toilet system shall meet its design requirements.
5.2.2 After a toilet flush signal is triggered, the toilet shall flush away the sewage into a
sewage tank through the blowdown pipe; when a passenger car and multiple unit is
running, the toilet system shall collect and store the sewage; when the passenger car and
area of the blowdown line.
5.2.11 A toilet system shall have emptying function so as to be able to empty all the water
and sewage in the system.
5.2.12 When collecting and storing sewage to the maximum alarm level, the toilet system
will automatically offer protection and shut down to stop service.
5.2.13 All exposed operable components shall be furnished with operation marks.
5.2.14 The leak tightness of a toilet system shall meet the following requirements.
a) No leakage of water or compressed air under normal operating conditions;
b) The airtightness of the vacuum toilet system that needs to produce vacuum in a
sewage tank shall meet the following requirements, at the highest operating
vacuum pressure when it has been installed.
— while the sewage tank, whose effective volume is 400L and above, hold the
press for 20min, the vacuum pressure rise shall not exceed 3kPa;
— while the sewage tank, whose effective volume is less than 400L, hold the
pressure for 20min, the vacuum pressure rise shall not exceed 5kPa.
5.2.15 The air consumption of a toilet system shall meet the following requirements (under
the standard atmospheric pressure).
a) The average compressed air consumption of vacuum retentive and intermittent
toilet systems in one flush cycle shall be less than (10+V) L;
b) The average compressed air consumption of a vacuum on-line toilet system in
every flush cycle shall be less than (50+W)L;
c) The average compressed air consumption of a vacuum push-pull toilet system in
every flush cycle shall be less than 60L;
d) The average compressed air consumption of a gravity toilet system in one flush
cycle shall be less than 10L.
Note. V is related to the sewage tank volume; the average compressed air consumption is 33L per 100L
sewage tank. W is related to the pipe length; the average compressed air consumption per 1m pipe is
30L when the length is greater than 1.5m.
5.2.16 When used in the areas where the ambient temperature is below 0°C, the toilet
shall have its under-car part furnished with an electric heater unit.
5.2.17 The weight of the components of a toilet system shall be satisfactory to the user.
