Dear Mr. Sorensen: 

We received your correspondence of September 7, 2021 requesting issuance of a reimbursement 

eligibility letter under the Federal-aid highway program for the roadside safety system, device, 

design, product, or hardware (collectively “device”) described below. This letter is assigned 

Federal Highway Administration (FHWA) control number B-368. 

ELIGIBILITY LETTERS

The FHWA issues Federal-aid reimbursement eligibility letters for new roadside safety devices

that are crash tested in accordance with the industry standard of the American Association of 

State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware 

(MASH). 

FHWA, the Department of Transportation, and the United States (government) do not regulate 

roadside safety devices, crash test facilities, or the manufacturing industry. Issuance of 

eligibility letters is discretionary and provided only as a service to the states. FHWA may, at its 

discretion, decline to issue, revise, or rescind an eligibility letter. Eligibility letters are only 

issued by the FHWA headquarters Office of Safety. 

Eligibility letters are issued only as notice to the states that a device is eligible for reimbursement 

under the Federal-aid highway program. They do not establish approval or certification for any 

other purpose. Issuance of an eligibility letter is not a prerequisite or requirement for state 

transportation agencies seeking to use Federal-aid funds for roadside safety devices. State 

agencies may use a device for which an eligibility letter has not been issued and seek Federal-aid 

reimbursement. 

FEDERAL-AID REIMBURSEMENT

The request for issuance of this letter certified the device was crash tested in accordance with the 

industry standard of AASHTO’s MASH. This eligibility letter is based on that certification and 

the material offered in support of its issuance. The device described below is eligible for 

reimbursement under the Federal-aid highway program.

Name of system: SAFENCE4RC-19CC3.0

Type of system: Longitudinal Barrier 

Test Level: Test Level 4 

Testing conducted by: Holmes Solutions and VTI 

Date of request: September 7, 2021 

Information about the device, including material such as the eligibility request, crash test reports, 

drawings, or images are included in one or more attachment(s) to this letter. 

Eligibility letter B-368 is inapplicable to devices, optional equipment, alternate materials, or 

other features that were not crash tested in accordance with AASHTO’s MASH. 

This letter is issued only for the subject device as crash tested under AASHTO’s MASH. Later 

modification(s) of the device are not eligible for Federal-aid reimbursement under this letter. 

Notice of later modification(s) should be given to transportation agencies, facility owners, and 

operators (collectively “agencies”). 

Agencies should be provided appropriate information about the device’s design, installation, 

maintenance, materials, and mechanical properties. 

 

Issuance of this letter is discretionary, and it may be revised or rescinded at FHWA’s discretion. 

This letter is not a determination of compliance with the Manual on Uniform Traffic Control 

Devices for Streets and Highways (MUTCD) or ownership of any intellectual property rights. 

This eligibility letter is not a determination by the government that a crash involving the subject 

device will result in any particular outcome. It is limited to only the device’s eligibility for 

Federal-aid reimbursement. 

INTELLECTUAL PROPERTY 

Issuance of this eligibility letter does not convey property rights of any sort nor any exclusive 

privilege. This letter is not authorization or consent by the government for the use, manufacture, 

or sale of any patented or proprietary system, device, design, product, or hardware for which the 

requester is not the patent owner. Eligibility letters are not an expression of any view, position, 

or determination by the government as to the validity, scope, or ownership of any intellectual 

property rights to a specific device. These letters do not grant, impute, suggest, or otherwise 

establish any ownership, distribution, or licensing rights to the requester. The government 

expresses no opinion about the intellectual property rights relating to any device for which this or 

any other eligibility letter is issued. 

PUBLIC DISCLOSURE

To prevent any misunderstanding, and as discussed above, this eligibility letter is assigned 

FHWA control number B-368. It should only be reproduced in full with its attachment(s). This 

letter and the material offered by the requester supporting its issuance is public information. All 

eligibility letters and supporting material are subject to public disclosure under the Freedom of 
3 

Information Act (FOIA). Eligibility letters are available to the public at

PRODUCT DESCRIPTION 

A brief description of each crash test and its result: Help 

New Hardware or

Significant Modification

Modification to 

Existing Hardware 

The SAFENCE 4RC-19Blue SystemsCable Barrier System used in this test series consist of four 19 mm 

(0.75”) 3x7 strand wire rope cables. Wires are attached to the post through thecentral slot detail andcap 

assembly in the post. The cable cross-section diameter is 20 mm and the wire ropes were attached at

heights of 570 mm, 670 mm,780 mm, and 800 mm above ground level. Cable height is measured from 

center of cable to ground.The overall barrier length was 188.4 m.

The system should be installed with post spacing of 3 meter. All posts should be installed in concrete 

foundation 600 mm deep x 300 mm diameter into AASHTO standard soil.

Test 4-10 and 4-11 were conducted at HolmesSolution. This Request forEligibility Form isfor those two 

tests. Test 4-12 were conducted atVTI, anda Request forEligibility Form will besubmitted for that test to 

complete the test series forTL4. 

CRASH TESTING 

By signature below, the Engineer affiliated with the testing laboratory, agrees in support of this submission that 

all of the critical and relevant crash tests for this device listed above were conducted to meet the MASH test 

criteria. The Engineer has determined that no other crash testsare necessary to determine the device meets 

the MASH criteria.

Results 

4-10 (1100C) 

The test was conducted with a 1100C

vehicle impacting the test installation 1.39m

upstream from steel post 20at an angle of

24.8 degrees, and a velocity of 100.4 km/h. 

The maximum roll of the vehicle at 11.4

degrees during impact. The maximum 

working width of the system was recorded 

as 1.71 m. The maximum dynamic 

deflection of the system wasalso recorded 

at 1.71 m. The system successfully 

contained and redirected the test vehicle. 

No debris or detached elements penetrated 

or showed potential to penetrate the

occupant compartment. No fragments were 

distributed outside of the vehicle trajectory. 

The trajectory of the vehicle wassuch that it

did not present any undue hazard to other 

traffic, pedestrians, or work zone personnel. 

The vehicle remained upright during and 

after the impact and vehicle stability was 

considered satisfactory. The system 

successfully contained and redirected the 

test vehicle. The SAFENCE 4RC-19 cable 

barrier system was judged to have satisfied 

all the evaluation criteria for the MASH Test 

4-10.

system was recorded as 2.19 m. The 

maximum dynamic deflection of the system 

wasalso recorded as 2.19 m. The system 

successfully contained and redirected the 

test vehicle. No debris or detached 

elements penetrated or showed potential to

remained upright during and after the

impact and vehicle stability was considered 

satisfactory. Occupant risk factors satisfied 

the test criteria and the vehicle exit 

trajectory remained within acceptable 

limits. The SAFENCE 4RC-19 cable barrier 

system was judged to have satisfied all the 

evaluation criteria for the MASH Test 4-11.

RIGGING SCREW ASSEMBLY 

Rigging screws are to be mounted at every linear 

+50 +25 300 -0 m and at 150 -0 linear metres from

anchoring point.

Wire fittings are swaged into the cables with 

A-400RS-AV297 and pulled with 070827-03. After 

tension force according to Tensioning Table T2 is 

reached, AD-3023A is locked with DIN 934 M24 or 

equivalent. 

Mounting is generally not recommended in horizontal 

curves with a radius <400m.

Mounting in vertical curves should not be executed in 

depressions with a radius <1 200m.

For futher enquiries or specific advisement regarding 

installment or working features of SAFENCE, please 

contact Blue Systems. 

Lateral movement to bypass 

obstacles (bridge piers etc.) are to 

be conducted gradually to prevent 

posts from being exposed to very 

high transverse forces.
