Statement of Work for Weathering of Laminated Glazing Units

Background

The Department’s Bureau of Diplomatic Security (DS), Research and Development Branch (DS/PSD/RD) requires long-term weathering of Ethylene Vinyl Acetate (EVA) and PolyVinyl Butaryl (PVB) laminated glazing units to support recent blast testing research of EVA laminated windows. Prior to use of the EVA laminate in any Department of State projects, long-term weathering degradation of the bond between EVA and glass as well as any degradation to the EVA laminate itself must be investigated.

Weathering

Weathering shall be performed on six (6) 68” by 44” laminated glazing panels. Natural weathering shall be performed in accordance with natural exposure weathering method defined in Section 5.4.1(1) of ANSI Z97.1-2015 (R2020), except that the duration of testing shall be ten (10) years.

Perform the tests defined in Sections 5.4.2(1) and 5.4.2(3) of ANSI Z97.1-2015 (R2020) on a yearly basis for the duration of the testing.

At the completion of testing, the weathered laminated glazing units shall be shipped to a testing house for blast testing. The test house shall be determined prior to year ten (10) of the weathering period.

Contracting

Contracting shall be initiated for a Base One (1) Year Contract with options for Nine (9) One (1) Year contracts in order to complete the desired ten (10) year weathering cycle. Depending on each one (1) year weathering result reports, and each subsequent year results, DS may exercise another Option to continue weathering in one (1) year increments.

Deliverables

Weathering reports shall be in accordance with the contract labs procedures or per any reporting requirements in ANSI Z97.1-2015 (R2020), whichever is more stringent, but not less than one (1) report per contract year. The weathering report shall be issued at a time that shall allow DS/PSD/RD to review and determine if another option year shall be exercised. A final report shall be provided after completion of the ten (10) year weathering cycle or at the time it is determined weathering shall be terminated. Reports shall be emailed to Phillip Benshoof and Craig Ackerman at BenshoofPC@State.gov and AckermanCR@state.gov. Any hard copy reports shall be mailed to the following address:

mailto:BenshoofPC@State.gov mailto:AckermanCR@state.gov

Attention: Phillip Benshoof

Reporting of funding expenditures shall also be submitted to the above email or physical address no less than one (1) time per year.
