System tested in accordance with EN 1317

General Information

According to Section 9 of the “Guidelines for the Installation of Additional Devices on Vehicle Restraint Systems – H ZFRS” issued by the German Federal Highway Research Institute (BASt), the permanent installation of anti-glare screen systems requires testing of the combined system consisting of the vehicle restraint system and the anti-glare screen system in accordance with DIN EN 1317.

From 01 January 2026 onwards, only anti-glare screen systems may be used that have successfully passed at least a TB32 impact test and for which no components > 2 kg have become detached.

Our Test Certification

Our anti-glare screen system was tested:

• as a combined system with the vehicle restraint system
• in an impact test according to DIN EN 1317
• at least in accordance with TB32
• without detachment of components > 2 kg

and successfully passed the test.

Our system therefore complies with the requirements of H ZFRS (BASt 2023) for tested anti-glare installations.

Components

• Our support tube brackets are individually adapted to the respective substructure and securely attached to it. The extended insertion length allows compensation for longitudinal differences or deviations in curved sections.
• The hot-dip galvanized square tube 45 × 45 × 2 mm (standard length 3,960 mm; special lengths available) is clamped to the support tube brackets using two bolts.
• The louver bracket connects the support tube to the plastic louver. Fixed-angle brackets are clamped to the support tube with one bolt and can be adjusted longitudinally. Rotatable louver brackets are secured to the support tube using a through-bolt.
• The plastic louvers are fully enclosed, oval hollow profiles made of green-dyed high-density polyethylene (HDPE). They are fastened to the louver brackets with four bolts. Standard heights: 600 mm, 900 mm or 1,200 mm.

Technical Requirements in Accordance with H ZFRS

H ZFRS requires, among other things:

• Compatibility of the anti-glare screen system with the respective vehicle restraint system
• Positive-fit and friction-locking fastening
• No sharp-edged or aggressive structural components
• Avoidance of tensile band effects in the event of impact
• Testing of the combined system in accordance with DIN EN 1317 (minimum TB32)

These requirements were considered and verified during the system testing process.

Technical Note for Tendering and Planning

• Testing as a combined system of anti-glare screen and vehicle restraint system in accordance with DIN EN 1317
• Testing of the anti-glare screen system in accordance with DIN EN 12676
• Successful TB32 impact test
• Compliant with Section 9 “Anti-glare installations” of H ZFRS (BASt, as of 28 August 2023)
• Applicable in accordance with the regulation effective from 01 January 2026
