This is a continuation sheet for a federal solicitation (RFQ/RFP) documenting a supply requirement for pressure gages. The document specifies the procurement of six (6) Ashcroft Model 1279 pressure gages with a 0-1500 PSIG range, unit of issue in each (EA).

The specifications outline detailed technical requirements for the gages, including a 4-1/2 inch diameter dial with 5 PSI maximum graduation increments, solid front case with blow-out rear cover, laminated safety glass window, and stainless steel Bourdon tube. The gages must feature slotted link movement protection against sudden pressure decrease and connect via a 9/16-18UNF-3A stainless steel male straight thread O-ring seal at the bottom (6 o'clock) position per Ashcroft drawing 70A100 and MIL-G-18997E. The gages must meet ASME B40.100-2013 Grade 2A accuracy standards with oxygen cleanliness and marking per ASME B40.100-2013 Level IV cleanliness requirements and be mercury-free. Accuracy testing is mandated at minimum ascending test points of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100% of full scale, and descending test points of 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, and 10% of full scale plus zero. The warranty requirement specifies that gages must perform according to Heise gage specifications.
