2_JA Charpy Impact Tester 25JUN2025_Rev1_KO Signed (copy)_Redacted.pdf

This document is a Contracting Officer's Determination Memorandum for Sole Source Purchase, specifically for one (1) Model IT406 Motorized Pendulum Charpy Impact Tester with Digital Display, Enclosure, and 110VAC. The tester is required for impact testing of weld procedure qualification specimens per Mil-Std 3040. The sole source justification stems from a previous incorrect purchase of a Charpy Impact Tester on 02 February 2023, which was ordered without essential features like enclosure and auto lift/return. After a safety review, only a Tinius Olsen Charpy Impact Tester can meet the specific requirements, as components from other manufacturers would compromise equipment safety, void the OEM warranty, and prevent proper testing for Procedure Qualification Records. The procurement emphasizes the need for a seamless fit between parts, valid warranty, safe equipment use, and reliable test results.
