Methodology statement

A single statement of the calculation methodology and the specific standard each tool follows (ASME, API, NFPA, ISA, IEC, ISO), so a result can be defended and audited against a named clause.

• A client or AHJ asks which code edition or method a number came from
• You're compiling a design basis and need a citable methodology reference
• You want one page to confirm DekEn isn't quietly using a different standard than the one you assumed

Lists, tool by tool, the exact standard/correlation applied (e.g. API 520 Part I for PSV sizing, IEC 61508-6 Annex B for PFDavg), kept in sync with the calculators as they change.
