// Calibration laboratories · Out-of-tolerance notices
Out-of-tolerance notices, drafted from the as-found readings your technicians recorded.
When an instrument arrives outside its tolerance, the customer needs to hear what was found, in the form their own quality system expects. A free AI proof of concept has AI draft those notices from copies of 20 to 30 failures your lab has already reported. Your reviewer, usually the quality manager who signs them today, holds each draft against the notice that actually went out.

// The one job
From an as-found failure to a notice the customer can act on
A technician records the as-found readings, sees one or more points outside the tolerance the job was run to, and flags the work order. Then someone on the quality desk gathers the instrument details, the failing points, what was adjusted or repaired, and the account's written terms on how and when they want to hear about it, and writes the notice for the quality manager to sign.
In the proof of concept, AI does that gathering on copies and drafts each notice: the instrument, the readings exactly as recorded with the tolerance and its source, what happened to the instrument afterward, the customer's notification term it answers, and a list of anything missing. It sends nothing. Your reviewer compares every draft with the notice your lab sent for the same failure.

// What makes it hard
Where an out-of-tolerance notice goes wrong
Out of whose tolerance? The customer may not judge the instrument by the limits you ran it to. The equipment calibration SOP published by the Frederick National Laboratory for Cancer Research defines out of tolerance against its own specified level of calibration, which can differ from the manufacturer's, so failing the maker's specification may not count. It says plainly that an out-of-tolerance condition its calibration vendor reports may not be one under its process tolerance, and that its quality engineer decides. So the draft names the limit every reading was judged against and where that limit came from: the maker's specification, a customer tolerance on the PO, or your procedure.
The notice feeds someone else's remedial action. Drug makers calibrate under a written program that 21 CFR 211.160 says must include specific directions, schedules, limits for accuracy and precision and provisions for remedial action when those limits are not met, and an instrument that doesn't meet its specifications may not be used. Device makers have worked under FDA's Quality Management System Regulation since February 2, 2026, which brings ISO 13485:2016 into Part 820 by reference. Frederick's SOP expects its vendor to notify it and offer options when an out-of-tolerance instrument can't be put right. Each account's terms decide who gets the notice, by when and in what form, and the draft quotes the term it is answering.
Condition on arrival is part of the story. A nonconformance guide from one of NIST's own calibration divisions lists shipping damage among the causes, has the client told when an item fails inspection, allows repair only on the client's written request, and has an item that behaves against its design reported to the client at once. For labs that seek recognition under it, the optional ANSI/NCSL Z540-1 annex in NVLAP's handbook calls for tamper-resistant seals on adjustments whose removal would invalidate a calibration, and for instructions on equipment whose seals are damaged or broken. NIST's example certificate shows the matching fields: conditions of the items as submitted, such as fingerprints and dents, and any cleaning done before calibration. The draft carries those notes exactly as recorded.
Some failures have no as-found reading at all. Frederick's vendor letter asks for a written statement with the certificate when a unit arrives inoperable, and its SOP needs no as-found data for new equipment. ILAC's uncertainty policy normally leaves transport effects out of the stated uncertainty and asks the lab to raise them at contract review if it expects them to matter. So a reading taken after a rough trip is reported as recorded, with the stated uncertainty copied from your data, and nothing recalculated. A blank as-found field goes on the missing list, never filled in.
Facts and opinions travel separately. A2LA's rules on references to its accreditation want any opinion or interpretation outside the accredited work marked with a disclaimer, and prefer it on a separate letter without the symbol. The impact on the customer's product is the customer's question: Frederick's SOP has each out-of-tolerance event investigated for its effect on product inside its own program. The NIST guide also has a client who accepts nonconforming work say so in writing, kept on file and noted in the report. Your reviewer will check that each draft states facts only, names the customer's term, and lists what the file doesn't hold, such as an account with no notification term on record. These rules are summarized for context, not as legal or technical advice.
// What you send
Copies from your quality desk
20 to 30 past failures
Each with its as-found data sheet, the work order, the certificate and the notice your lab sent. Include a repair, an inoperable arrival and one where the customer's tolerance differed from the maker's.
Each account's notification terms
Quality agreements, PO cover letters or emails that say how a customer wants to hear about an out-of-tolerance instrument, by when and to whom.
Your own procedure
The procedure your quality manager follows for these notices, and the template or letter format your lab uses today.
NDA, then copies
Nothing is copied before the NDA is signed. Nobody here signs in to your calibration software or a customer's supplier portal, and if customer details can't leave, your reviewer helps us build look-alike failures.
// Before it starts
Settled before any failure is copied
The owner signs off on these while every notice is still in the lab's files.

| Across the same 20 to 30 failures | Notice your lab sent | Draft from the test |

| Instrument identified the way the customer's records name it | Filled in on your notices | Filled in on your notices |
| As-found readings carried exactly as recorded | Filled in on your notices | Filled in on your notices |

| Repair, adjustment or inoperable status stated | Filled in on your notices | Filled in on your notices |
| Customer's notification term named and answered | Filled in on your notices | Filled in on your notices |

// After a yes
About 30 days on new as-found failures
After a yes from your reviewer, new failures get drafted the same way for roughly 30 days.
Each notice waits for your quality manager, who edits, signs and sends it the way your lab does now.
Scoring continues on the live notices. Any second job is a new decision at its own price.

// One hard limit
The AI never decides tolerance or sends a notice.
It drafts from copies of failures your lab already recorded and reported. It never judges whether an instrument was in or out of tolerance, never computes an uncertainty, never assesses impact on a customer's product, never contacts a customer and never touches your calibration system, a customer portal or a live notice. Your quality manager decides, signs and sends every notice.
Priced per job. You get a range before the proof of concept and a fixed price before you sign.
The range comes on the call, once Rob knows how many out-of-tolerance notices go out in a month and how many accounts have their own written terms for them.
// Questions
What quality managers ask about notices
Does the AI decide that an instrument was out of tolerance?
Will the notice tell our customer what the failure means for their product?
What if a customer has no written notification term?
Can it handle instruments that arrived broken?
Does the test touch our calibration software or customer portals?
