Solving problems related to the description of pipeline material tables

I have received a specification sheet for pipes, with the following details: Pipe, DN100, SCH10, A358-304L, CL.5 (J.F=0.90), EFW, PE, 13, ASME B36.10M. Does anyone who is experienced in design know what J.F=0.90 and 13 mean respectively?
I have received a specification sheet for pipes, with the following details: Pipe, DN100, SCH10, A358-304L, CL.5 (J.F=0.90), EFW, PE, 13, ASME B36.10M. Does anyone who is experienced in design know what J.F=0.90 and 13 mean respectively? Nominal diameter 100, pipe schedule SCH10, material 304L stainless steel; JF is likely the welding coefficient, EFW is electrofusion welding, PE means flat end, and the size standard is ASME36.10
J.F=0.90 is the longitudinal weld coefficient for welded steel pipes. A358 CL.5 requires double-sided welding with partial radiographic inspection; therefore, according to ASME B31.3, the longitudinal weld coefficient should be 0.90. This 13 is really impossible to guess; normally, this parameter doesn’t exist.
