Since January 2023, there has been a new marking of tanks in the ADR regulations: The SV sign to identify tank vehicles equipped with a safety valve. (ADR 2023, Part 2, 6.8.3.2.9.6, p. 509)
This applies to tanks that transport flammable liquefied gases (safety valve obligation).
Tanks that transport compressed gases, non-flammable liquefied gases or dissolved gases may be fitted with a safety valve. If this is the case, marking with the SV sign is also mandatory.
Characteristics of the SV sign - material and sizes
The sign consists of a white background with black letters "SV" and a black line inside the edges of the sign.
The material used must be weather-resistant and it must be ensured that the marking is permanent.
The sign must not become detached from its holder after 15 minutes of exposure to fire. It must remain attached regardless of the orientation of the tank.
The letters "SV" must be indelible and still legible after 15 minutes of exposure to fire.
The SV mark is available in two sizes for different tank capacities
- 250 x 250 mm for demountable tanks / tank containers with a capacity of over 3000 liters
The letters "SV" must have a character height of at least 120 mm and a line width of at least 12 mm.
The distance between the black line and the edge of the license plate must be approx. 12.5 mm. - strong>120 × 120 mm for demountable tanks / tank containers with a capacity of up to 3000 liters
The letters "SV" have a character height of at least 60 mm and a line width of at least 6 mm.
The distance between the black line and the edge of the sign must be approx. 6 mm.
Where must SV signs be mounted?
The plates must be A) affixed to both long sides and the rear end of fixed tanks (tank vehicles) and B) to both long sides and each end of demountable tanks.
C) The markings must be affixed to both long sides and to each end of tank containers. D) For tank containers with a capacity of less than 3000 liters, the SV plates may be mounted either 1 on both long sides or 2 on both ends.
E) The following applies to rail vehicles: The plates must be affixed to both long sides of the tank wagon.
