Material Verifications

Pratt & Whitney's XRM document specifies the requirement for dimensional and alloy verification. RAY-CHECK MFG. (RCM) verifies dimensions and issues an analytical report with I.Q.I's. RCM performs alloy verification in accordance with PWA MCL Sec. F-53 (thermo-electric testing).

Material certifications accompany alloy verification documents.

Aluminum and Magnesium alloys are sent out for semi-quantitative spectrographic analysis in accordance with PWA MCL Sec. F-23 and F-54.
