Intry Verified receipt

Is the Intry Vacuum Decay Test Calculator accurate?

The provenance receipt for the Intry Vacuum Decay Test Calculator: the exact authority its values derive from, the edition they are keyed to, who has final say, and what our automated checks hold them against, rebuilt from their cited source.

Short answer: Every figure an Intry calculator computes comes from a locked source module, not hand-typed. 29291 automated checks re-derive those figures and re-check the manufacturer method this tool applies before each deploy. The standard it judges your reading against is the hold criterion in the installation instructions for your equipment, which you supply, judged alongside the vapor pressure of water derived from the NIST Antoine coefficients, so no check of ours can confirm that what you entered is what is printed on your equipment. 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 installation instructions for your equipment (the hold criterion) · Trane Installer's Guide, Condensing Units, 18-AC98D1-5-EN (4TTR6018-061) · Goodman / Amana Condensing Unit Installation & Service Reference, IOG-4036B, December 2022 · York Installation Manual, R-410A 2-Stage Outdoor Split-System Heat Pump, 5391577-UIM-B-0718 (YZT, HC19B, HL19B) · Rheem / Ruud Variable Speed R-454B Heat Pump Outdoor Units Installation Instructions, 92-110354-01-01 · Carrier 26SCA5 Installation Instructions, 26SCA5-1SI, Edition Date 06/24 · Daikin Room Air Conditioner Installation Manual, 3P740830-1B · Daikin VRV Commissioning Guide (a training handbook, not an installation manual), VRV III Pre-Commissioning Check #3 · NIST Chemistry WebBook, Antoine parameters for water (Bridgeman & Aldrich, 1964). Reused verbatim from the locked engine, never re-written for this page.
Checked
Before any release, an automated check rebuilds the calculated figures from the locked engine that produces them and holds each one against the source it cites, so a number answers to its source and not merely to itself. As of the current build that suite holds 29291 checks, and this page has to clear them too. This is our own deterministic gate, not a third-party audit.
Runnable
A reference engine behind the published numbers on this site. Runnable access is offered on the calculators exposed at the Intry MCP endpoint.
Final say
The installation instructions for your equipment have final say on the hold criterion, and a nitrogen pressure test is what locates a leak. A system that holds a vacuum has not been pressure tested.
