This is an attachment continuation sheet specifying the technical requirements and quality standards for a Z-Block Fabric procurement. The requirement is for 10 rolls of Z-Block fabric, a high-temperature polymer-coated fiberglass material measuring 38 mils thick by 60 inches wide by 50 yards per roll, with a silver finish and flame-retardant properties rated for 1800°F. The fabric must satisfy multiple rigorous testing standards including ASTM D6413 for vertical flame resistance, ASTM E-84 for surface flame spread and smoke sensitivity, ASTM F955 for molten metal splash resistance, 14 CFR Appendix F for flame penetration and smoke density, and BSS 7239 for combustion toxicity. The material must not produce hazardous outgassing and is subject to C528 specification changes.

The procurement is a Total Small Business Set-aside Request for Quotation issued by the Naval Sea Systems Command for Portsmouth Naval Shipyard in Kittery, Maine, with a required delivery date of April 24, 2026 (ASAP). The NAICS code 314999 applies with a small business size standard of 550 employees. This is a brand name mandatory acquisition, meaning proposed alternatives will be rejected. Vendors utilizing authorized distributors must provide proof of availability and confirmed lead time at time of quote. Inspection and acceptance occur at destination, with commercial packaging acceptable for preservation and delivery. Past performance will be evaluated using PPIRS/CPARS information, and award may be based on schedule adherence and soonest mobilization. Vendors must provide price breakdowns and technical information for evaluation purposes.
