Intry Verified receipt
Is the Intry Nitrogen Pressure Test Calculator accurate?
The provenance receipt for the Intry Nitrogen Pressure Test Calculator: the exact authority its numbers derive from, the edition they are keyed to, who has final say, and how a deploy gate re-checks its numbers against their cited source.
Short answer: Every figure an Intry calculator computes comes from a locked source module, not hand-typed. 9547 automated checks re-derive and source-check the numbers against the NIST standard-atmosphere and Rankine constants it was computed from before each deploy. This is our own deterministic gate, not a third-party audit. The per-tool receipt is public at https://www.intrysys.com/verified.
The receipt
- Calculated from
- the NIST standard-atmosphere and Rankine constants it was computed from. Reused verbatim from the locked engine, never re-written for this page.
- Checked
- Before any deploy, a deterministic test suite re-derives calculated figures from their locked source module and source-checks the numbers against what they cite, so a number is held to its real source, not just to itself. As of the current build that suite holds 9547 checks, and it gates this page too. This is our own deterministic gate, not a third-party audit.
- Runnable
- A reference engine that powers the published numbers. It is not exposed as a runnable MCP tool.
- Final say
- The equipment manufacturer and your AHJ have the final say on the required test pressure, the hold time, and pass or fail.
