THIS IS RABS

RABS is the designation for vehicle screens which indicates that the screens satisfy a combination of international safety standards. In order to be marked "RABS Approved", the screens must pass all of the following four tests. Using a RABS-classified solution satisfies personal protection requirements for work involving the risk of undetonated explosives, falling rocks and while quarrying. Hammerglass in a steel frame satisfies the RABS requirements.

R43 ECE Regulation No.43 (R43). A comprehensive series of tests for vehicle glass, including scratch protection, UV protection and elongation. Compulsory for all vehicles.
AXE Sharp object (EN 356, P8B), a test in which the screen withstands 72 blows from a machine-mounted axe, without the axe penetrating the glass.
BLAST Pressure wave upon detonation (EN 13124-2, EXR 2), a test in which 3 kg (6.6 lbs) TNT are detonated at a distance of 3 meters (9.8 feet) from a screen mounted in an approved steel frame. The screen is mounted in a steel frame so that they cannot be forced into the cab.
STONE Heavy objects at high speed (EN 15152-2), a test in which a 1 kg (2.2 lbs)aluminium projectile is propelled against the screen at a speed of 450 km/h (280 mph) and at an angle of 90 degrees thereto. Equivalent to a large rock propelled at high speed.
FOPS Falling Object Protective Structure/FOG Falling Object Guard (EN ISO 3449, ISO 10262, ISO 8083). A test where the system is frozen to -18°C, after which a 227 kg heavy steel cylinder is released from a height of 5.2 meters onto the window (corresponds to a force of 11,600 Joules).
