•	weighing method (for example, full draught weighing or partial weighing; uncoupled wagon, coupled wagon or train weighing; weighing-in-motion or static)
•	maximum wagon weight	... ... ... ...kg or t
•	minimum wagon weight	... ... ... ...kg or t
•	not to be used to weigh liquid products (if applicable)
•	full draught or number of partial weighings per wagon
•	maximum transit speed	... ... ... ...km/h
•	direction of weighing (if applicable)
•	wagons pushed/pulled (whichever is applicable)
•	scale interval for stationary load (if applicable)	... ... ... ...kg or t
•	electric power supply voltage	... ... ... ...V
•	electric power supply frequency	... ... ... ...Hz

Markings shown in code

3.6.2.

For all instruments

•	pattern approval sign in accordance with national requirements
•	accuracy class (for each weighing method, if applicable)	0.2, 0.5, 1 or 2
•	maximum capacity	Max = ... ... ... ...kg or t
•	minimum capacity	Min = ... ... ... ...kg or t
•	scale interval	d = ... ... ... ...kg or t
•	maximum operating speed	vmax = ... ... ... ...km/h
•	minimum operating speed	vmin = ... ... ... ...km/h

For coupled wagon and train weighing

3.6.2.2.  Markings required for each weighing method applicable:

•	maximum number of wagons per train	nmax = ... ... ... ...
•	minimum number of wagons per train	nmin = ... ... ... ...

Supplementary markings

3.6.3.  Depending upon the particular use of the automatic rail-weighbridge, one or more supplementary markings may be required on pattern approval by the metrological authority issuing the pattern approval certificate.

Other markings

3.6.4.  The designation of the liquid(s) which the automatic rail-weighbridge is designed to weigh (if applicable).

Presentation of descriptive markings

3.6.5.  Descriptive markings shall be indelible and of a size, shape and clarity that permit legibility under normal conditions of use of the weighbridge.

• Markings shall be grouped together in a clearly visible place on the weighbridge, either on a descriptive plate fixed near the indicating device or on the indicating device itself.

• It shall be possible to seal the plate bearing the markings, unless it cannot be removed without being destroyed.

Verification marks

3.7.

Position

3.7.1.  Automatic rail-weighbridges shall have a place for the application of verification marks. The following applies for this place:

• the part on which the marks are located cannot be removed from the weighbridge without damaging the marks;

• the place shall permit the easy application of the marks without changing the metrological qualities of the weighbridge;

• the marks shall be visible when the weighbridge is in service.

Mounting

3.7.2.  Automatic rail-weighbridges required to bear verification marks shall have a verification mark support located as specified above, which shall ensure the conservation of the marks as follows:

• when the mark is made with a stamp, the support may consist of a strip of lead or any other material with similar qualities inserted into a plate fixed to the weighbridge or a cavity bored into the weighbridge.

Additional descriptive marking

Automatic rail-weighbridges shall bear the additional descriptive marking “R 106” which shall be presented in accordance with the provisions of clause 3.6.5 of Part 1 of OIML R 106.
