Manufacturing Record Book (MRB)

What it is
A manufacturing record book (MRB), also called a final data book or manufacturing data record (MDR), is the supplier's indexed file of quality records for an order. It proves the equipment was made, inspected and tested as the purchase order required. It is usually compiled to the customer's index at handover.
Key Takeaways
- MRB, MDR, MDB and final data book usually name the same deliverable.
- The customer's index sets the sections and their order.
- Most of its records come from the inspection and test plan steps.
- Write the full name: MRB also means material review board.
Why it matters
A manufacturing record book (MRB) holds the as-built quality records for an order: material certificates, welding and NDE records, heat treatment, test and calibration records, the signed inspection and test plan, approved drawings, and NCRs or concessions. It is usually compiled to the customer's own index, often as one bookmarked PDF, and is one of the last items on the vendor data requirements list. Many purchase orders tie the final payment to its acceptance. The same deliverable is also called a final data book, manufacturing data record (MDR), manufacturing data book (MDB) or final documentation dossier. In quality management the letters MRB also stand for material review board, a team that decides what to do with nonconforming parts, so the full name is safer in writing.
How OdysseyGPT uses it
OdysseyGPT checks record books; it does not build them. The MRB Readiness Check (beta) compares your folder with the customer's index and flags missing, wrong-revision, incomplete or unapproved documents. MRB Traceability Verification (beta) checks the links between records. The MRB Compiler (beta) maps approved documents to the index and produces a cited compilation manifest; it does not assemble the final PDF.
Evaluation questions
When is the MRB delivered?
Usually at or soon after shipment, once every record is complete. The purchase order or VDRL sets the date, and payment is often tied to the customer's acceptance.
How does an MRB relate to a turnover package?
A turnover package is the contractor's wider handover set for a system or project. Each supplier's manufacturing record book often becomes one part of it.
Why are record books rejected?
Mostly for missing, superseded or unapproved documents, heat numbers that do not match certificates, welds with no NDE report, test instruments with no valid calibration, and unsigned ITP steps.
Frequently asked questions
What does MRB stand for in manufacturing?
In equipment supply and handover, MRB usually means manufacturing record book: the file of quality records for an order. In quality management it can also mean material review board, the team that decides on nonconforming parts. Context tells you which.
Is an MRB the same as an MDR or a final data book?
Usually, yes. Manufacturing record book, manufacturing data record (MDR), manufacturing data book (MDB) and final data book are company names for the same as-built quality file. Read the purchase order's definition, because a few buyers use the terms differently.
What is in a manufacturing record book?
Typically the certificate of conformity, approved drawings and datasheets, the signed ITP, material certificates, welding and NDE records, heat treatment records, test reports, calibration certificates, dimensional and coating records, and NCRs or concessions, in the order the customer's index sets.
Who decides the MRB index?
The customer, usually. The index may come with the purchase order or the quality specification, or only on request. Ask for it at kickoff so records are filed in the right order as the job runs.
