RSA 21: Barrier Fence Regulations - EURO1, EURO2, RA1, RA2
Important since February 2022: With RSA 21, RA2 reflective foil became mandatory for transverse barriers on roads. EURO1 (RA1) may only be used for longitudinal barriers.
Quick Overview: Which barrier fence for which application?
| Application | Required reflective class | Barrier fence type |
|---|---|---|
| Longitudinal barrier Along the road |
RA1 sufficient | EURO1 or higher |
| Transverse barrier Across the road |
RA2 mandatory | EURO2 or higher |
| Private/company premises | No requirement | EURO1 sufficient |
| Fall protection (>1.25m depth) | Depending on location | EURO2/EURO3 recommended |
Reflective classes RA1, RA2 and RA3
The reflective classes according to DIN 67520 indicate how well the foil reflects incident light back. The higher the class, the better the visibility at night.
RA1 - Low luminance
- Residential streets
- Side streets
- Parking lots
- Longitudinal barriers
RA2 - Medium luminance
- Main roads
- Federal roads
- Transverse barriers
- Intersections
RA3 - High luminance
- Motorways
- Expressways
- High-speed roads
EURO1 vs EURO2 - The important difference
EURO1 Schrankenzaun
RA1 Reflective foil
Approved for:
- Longitudinal barriers in StVO area
- All applications on private property
- Company premises
NOT approved for:
- Transverse barriers on public roads
- Intersections
EURO2 Schrankenzaun Recommended
RA2 Reflective foil
Approved for:
- Transverse barriers on public roads
- All longitudinal barriers
- Intersections
- Private and company premises
RSA 21 compliant - Can be used universally
TL foot plates - Mandatory for StVO area
Important: Without TL-approved foot plates of weight class K1, barrier fences are not approved for use on public roads!
Requirements for K1 foot plates:
- Waga: approx. 28-29 kg (stability class K1)
- Wymiary: approx. 80 × 40 × 12 cm
- Materiał: Recycled plastic, frost/oil/salt resistant
- Tested according to TL mounting device
- Receptacles for various post sizes
Additional requirements for transverse barriers
According to RSA 21, transverse barriers on roads require additional equipment:
Guide beacons
At least one guide beacon must be placed next to the barrier (RSA 21 Part A, Chapter 3.4.2). For oblique transverse barriers, at least 4 guide beacons per blocked lane.
Warning lights
Warning lights must be attached to each guide beacon for transverse barriers. For pedestrians and cyclists, yellow omnidirectional lights at 1m intervals (transverse) and 9m intervals (longitudinal).
