I have to comply to ASME B31.3. And I need to use this According to the manufacturer website, it is made of semi-rigid nylon, 7300 psi (50 MPa) tensile strength, 300% elongation, 0.25" (6.35 mm) OD, 0.150" (3.81 mm) ID, 0.05" (1.27 mm) wall thickness, 1,000 psi (6.9 MPa) max working pressure, 3,000 psi (21 MPa) burst pressure. I am using it for 200 psi (1.4 MPa) max pressure, 150 psi (1 MPa) normal working pressure, straight, 1' (30 cm) length, nitrogen gas. Am I in compliance with ASME B31.3? What do I need to show to prove the compliance?

ASME B31.3 has a list of materials in Table B1. But nylon is not listed there.
Thank you.
