The ASME B31 .3 Code defines unlisted components as components not in Tables 326.1, A326.1, or K326.1. Unlisted components can have pressure ratings but the owner and/or the designer has the responsibility to verify that the design, materials, fabrication, examination, and testing of the component meet the requirements of ASME B31 .3 .

B16.4 2.5.2 does allow variances in excess of the rating which are the responsibility of the user.
