Dear Mr. Sorensen,

This letter is in response to your request for the Federal Highway Administration (FHWA) to review a roadside safety system for eligibility for reimbursement under the Federal-aid highway program.

Name of system: Safence TL-3 End Terminal with 2 m post spacing
Type of system: Three or Four cable wire rope barrier end terminal
Test Level: NCHRP Report 350 Test Level 3
Evaluation conducted by: Force Technology
Task Force 13 Designator: SEC09
Date of request: December 29, 2010
Date initially acknowledged: February 7, 2011
Date of completed package: December 5, 2011

Decision
The following device is eligible, with details provided in your December 29, 2010 request, attached as an integral part of this letter:

Based on a review of the analysis submitted by the manufacturer certifying the device described herein meets the crashworthiness criteria of the National Cooperative Highway Research Program (NCHRP) Report 350, the device is eligible for reimbursement under the Federal-aid highway program.  Eligibility for reimbursement under the Federal-aid highway program does not establish approval or endorsement by the FHWA for any particular purpose or use. 

The FHWA, the Department of Transportation, and the United States Government do not endorse products or services and the issuance of a reimbursement eligibility letter is not an endorsement of any product or service.

Requirements
Roadside safety devices should meet the guidelines contained in the National Cooperative Highway Research Program (NCHRP) Report 350 or the American Association of State Highway and Transportation Officials' Manual for Assessing Safety Hardware (MASH).

Description
The Safence four cable wire rope end terminal was the subject of the FHWA letters CC-93 and CC93A dated 8/16/2005 and 12/28/2006, respectively. The posts in the terminal section were spaced 1 meter apart. Your present request is to increase that spacing to 2 meters for the length of the terminal. The test-by-test engineering analysis conducted by Force Technologies, enclosed for reference, shows that increasing the post spacing is not expected to have any adverse affect on the crash performance of the terminal. This modification may be used with three cable barrier terminals as well.

Findings
Therefore, the system described and detailed in the attached form is eligible for reimbursement and may be installed under the range of conditions tested.

Please note the following standard provisions that apply to FHWA eligibility letters:

 

Sincerely yours,
