Requirements 

To be found eligible for Federal-aid funding, roadside safety devices should meet the crash test 

and evaluation criteria contained in the NCHRP Report 350 or the American Association of State 

Highway and Transportation Officials' Manual for Assessing Safety Hardware (MASH). 

Description 

The devices and supporting documentation are described in the attached form. 

Summary and Standard Provisions 

Therefore, the systems described and detailed in the attached form are eligible for reimbursement 

and may be installed under the range of conditions tested. 

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

• 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 NCHRP Report 350 criteria 

will require a new reimbursement eligibility letter. 

• Should the FHW A 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 NCHRP Report 350. 

• To prevent misunderstanding by others, this letter of eligibility is designated as number 

WZ-329 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. 

• This letter shall not be construed as authorization or consent by the FHW A to use, 

manufacture, or sell any patented system for which the applicant is not the patent holder. 

The FHW A does not become involved in issues concerning patent law. Patent issues, if 

any, are to be resolved by the applicant. 

• The Dicke Tool Company portable sign stands are patented products and considered 

proprietary. If proprietary systems are specified by a highway agency for use on Federalaid projects: (a) they must be supplied through competitive bidding with equally suitable 

unpatented items; (b) the highway agency must certify that they are essential for 

synchronization with the existing highway facilities or that no equally suitable alternative 

exists; or (c) they must be used for research or for a distinctive type of construction on 

relatively short sections of road for experimental purposes. 
• Our regulations concerning proprietary products are contained in Title 23, Code of 

Federal Regulations, Section 635.411 .

PRODUCT DESCRIPTION

Acceptance of the TFl240 (aluminum legs) and STFl240 

(steel legs). 

Using the basic design of the TFl 230 stand (WZ-213) 

and STFl230 (WZ-250), the only change we are 

proposing is the conversion of the 3-stage mast to a 2-

stage mast. The stand weight, stand footprint and 

sign mounting height of the new stands are identical to 

the TF 1230 and STFl 230 stands. We believe 

this to be a reasonable request because the key design 

features are almost identical co the previously 

accepted stands. As such, we contend that there will be 

no effect on the windshield impact data. Crash testing 

of similar stands shows similar performance between 2-

stage and 3-stage masts, as per FHWA Lener WZ-213.

Dear Mr. Artimovich, 

This inquiry is regarding minor modifications to two (2) previously accepted stands. The new stands 

have slightly different mast configurations which are intended to satisfy customer field and storage 

requirements. A more complete description of each request follows: 

Request #1: 

Acceptance of the TF1240 (aluminum legs) and STF1240 (steel legs). 

Using the basic design ofthe TF1230 stand (WZ-213) and STF1230 (WZ-250), the only change we are 

proposing is the conversion of the 3-stage mast to a 2-stage mast. The stand weight, stand footprint and 

sign mounting height of the new stands are identical to the TF1230 and STF1230 stands. We believe 

this to be a reasonable request because the key design features are almost identical to the previously 

accepted stands. As such, we contend that there will be no effect on the windshield impact data. Design 

drawings for both are included for your reference. 

Request #2: 

Acceptance of the TF2008 (aluminum legs) and STF2008 (steel legs). 

Using the basic design of the TF1008 stand and STF1008 (WZ-250), the only change wc arc proposing 

is a minor dimensional change to each half of the 2-stage mast. The extended mast height will remain 

basically the same. In addition, the stand weigh, footprint and sign mounting height of the new stands 

are identical to the TF1008 and STF1008 stands. We believe this to be a reasonable request because the 

key design features are almost identical to the previously accepted stands. As such, we contend that 

there will be no effect on the windshield impact data. Design drawings for both are included for your 

reference. 
Should you need any further documentation, please let me know.
