KSA-S/1084: Ministry of Trade and Industry, License Number S/1084, Dated H 1425/7/23, Sending number 19/12027. Technical Test Rating using construction fundamentals mathematical formulas which guarantee the Structural Integrity above all case levels listed below. This License approval is based on impact resistance per meter of 40,000 kgs at 90 kms per hour with Zero Penetration. (same with a 100 story tower, its now possible to build 200 story structure without the use of structural proof guaranty. Crash test rating that indicates vehicle weight/speed during crash test and are based on the kinetic energy of the vehicle during impact. Results are normally combined with the L ratings with the absence of construction fundamentals mathematical formulas.

K: SD-STD-02.01 Revision B U.S. Department of State Designation crash test rating that indicates vehicle speed during crash test and are based on the kinetic energy of the vehicle during impact. Results are normally combined with the L ratings.

K and L Ratings: Ratings established by the U.S. Department of State test procedures in accordance with standard SD-STD-02.01. This standard specifies a vehicular impact (perpendicular to the barrier) of a 15,000-pound vehicle at a speed of 30, 40, or 50 mph.

K12: SD-STD-02.01 Revision B U.S. Department of State Crash Test rating indicating a barrier with this rating can withstand a 15,000-pound vehicle crashing perpendicularly into the barrier at 50 mph or 80 kph. Normally, the K ratings are combined with an L series penetration rating.

K4: SD-STD-02.01 Revision B U.S. Department of State Crash Test rating indicating a barrier with this rating can withstand a 15,000-pound vehicle crashing perpendicularly into the barrier at 30 mph or 48 kph. Normally, the K ratings are combined with an L series penetration rating.

K8: SD-STD-02.01 Revision B U.S. Department of State Crash Test rating indicating a barrier with this rating can withstand a 15,000-pound vehicle crashing perpendicularly into the barrier at 40 mph or 65 kph. Normally, the K ratings are combined with an L series penetration rating.

L: SD-STD-02.01 Revision A U.S. Department of State Designation crash test rating that indicates maximum allowed penetration of the barrier by the vehicle.

L1: SD-STD-02.01 Revision A U.S. Department of State Crash Test rating indicating a barrier with this rating can withstand a 15,000-pound vehicle crashing perpendicularly into the barrier with 20 feet to 50 feet of penetration (6.1 meters to 15.3 meters). Typically the L ratings are combined with one of the K speed ratings.

L2: SD-STD-02.01 Revision A U.S. Department of State Crash Test rating indicating a barrier with this rating can withstand a 15,000-pound vehicle crashing perpendicularly into the barrier with 3 feet to 20 feet of penetration (.915 meters to 6.1 meters). Typically the L ratings are combined with one of the K speed ratings.

L3: SD-STD-02.01Revision A U.S. Department of State Crash Test rating indicating a barrier with this rating can withstand a 15,000 pound vehicle crashing perpendicularly into the barrier with 3 feet or less penetration (.915 meters or less). Typically the L ratings are combined with one of the K speed ratings.
