Dear Mr. Smith:

This letter updates eligibility letter CC-100B issued on December 5, 2012 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:	Slotted Rail Terminal (SRT) MASH
Type of system:	Terminal End Section
Test Level:	MASH Test Level 3 (TL-3)
Testing conducted by:	Texas Transportation Institute
Task Force 13 Designator:	SEW12c
Date of request:	September 28, 2012
Date initially acknowledged:	September 28, 2012
Date of completed package:	October 16, 2012

Decision
The following device is eligible, with details provided:

• Slotted Rail Terminal (SRT) MASH

Based on a review of crash test results submitted by the manufacturer certifying the device described herein meets the crash test and evaluation criteria of the American Association of State Highway and Transportation Officials (AASHTO) "Manual for Assessing Safety Hardware" (MASH), the device is eligible for reimbursement under the Federal-aid highway program. FHWA is not revising the earlier eligibility determinations, but is updating this letter to address the statement in MASH that "Although not a specific factor in assessing test results, integrity of a test vehicle’s fuel tank is a potential concern. It is preferable that the fuel tank remains intact and not be punctured. Damage to or rupture of the fuel tank, oil pan, or other feature that might serve as a surrogate of the fuel tank should be reported." This letter is updated to note that a test report that accompanied your request for Federal-aid reimbursement eligibility (titled MASH TEST 3-30 on the SRT-MASH) indicated that there was "a hole in the oil pan." 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
To be found eligible for Federal-aid funding, roadside safety devices should meet the crash test and evaluation criteria contained in the MASH.

Description
The device and supporting documentation are described in the attached form.

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

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

• This letter provides a AASHTO/ARTBA/AGC Task Force 13 designator that should be used for the purpose of the creation of a new and/or the update of existing Task Force 13 drawing for posting on the on-line ‘Guide to Standardized Highway Barrier Hardware’ currently referenced in AASHTO Roadside Design Guide.
• This finding of eligibility does not cover other structural features of the systems, nor conformity with the Manual on Uniform Traffic Control Devices.
• Any changes that may influence system conformance with MASH criteria will require a new reimbursement eligibility letter.
• Should the FHWA discover that the qualification testing was flawed, that in-service performance reveals safety problems, or that the system is significantly different from the version that was crash tested, we reserve the right to modify or revoke this letter.
• You are expected to supply potential users with sufficient information on design and installation requirements to ensure proper performance.
• You are expected to certify to potential users that the hardware furnished has the same chemistry, mechanical properties, and geometry as that submitted for review, and that it will meet the crash test and evaluation criteria of the MASH.
• To prevent misunderstanding by others, this letter of eligibility is designated as number CC-100B and shall not be reproduced except in full. This letter and the test documentation upon which it is based are public information. All such letters and documentation may be reviewed at our office upon request.
