Use case · Datasheet review
Vendor and contractor datasheets compared field by field against your project specification and owner standard, with the governing clause and the evidence attached to every finding.
The problem
A specification package runs to hundreds of pages across datasheets, referenced standards and addenda. An engineer reads it and transcribes what matters into a review sheet. Missed fields and transcription errors enter right there, before any judgement is applied.
The parameters that fail are rarely the ones anyone was worried about. They are the ones nobody got to.
A datasheet has fifty or more fields. Each one may be governed by a different clause, in a different document, at a different revision.
Checking all of them properly takes longer than the schedule allows, so in practice reviewers check the ones experience tells them to.
What a review returns
Every parameter is compared against the requirement that governs it. Where a field fails, the finding names the document that ruled and quotes the line it came from, so the reviewer is checking a result rather than repeating the work.
| Parameter | Stated on datasheet | Governed by | Verdict |
|---|---|---|---|
| Design pressure | 51 barg | Project specification, rev 3 | MEETS |
| Minimum design temperature | −20 °C | Project addendum A-12 | BELOW MINIMUM |
| Body material | Carbon steel | Owner materials standard § 6.2 | NOT QUALIFIED |
| Service | Wet H₂S | Customer specification § 6.4 | MATCHES |
| Flange rating | Class 300 | Owner piping standard | MEETS |
| Capacity | 420 m³/h | Customer specification § 4.1 | MEETS |
Illustrative. The addendum governs the temperature limit, not the project specification, which is why the stated value fails.
Why the whole sheet matters
On the sheet above, design temperature looks compliant against the project specification. It fails because an addendum raised the limit, and the addendum governs.
A reviewer working from the specification alone would have passed it. That is not carelessness. It is what happens when the governing document for one field sits somewhere other than where you are looking.
HOW PRECEDENCE IS RESOLVED →Where it fits
Datasheet review runs on vendor submissions, contractor deliverables and your own engineering output. Upload a batch or pull them from connected cloud storage, run the project, and work the findings queue.

The same run covers drawings in the same project, and the findings carry into the same register.
FAQ
Engineering datasheet review is the check that every parameter stated on a data sheet meets the requirement that governs it. standrdX compares each field against the project specification, the owner standard and any addendum that modifies them, and returns a finding with the governing clause and the source quote attached.
Any datasheet supplied as a PDF, including vendor and contractor submissions, equipment and instrument sheets, and your own engineering output. Sheets arrive in batches or from your cloud storage, in the formats your suppliers already send.
Every field it can read is compared. Which findings matter is a severity question, and severity is proposed on each finding for the reviewer to accept or override.
That is the case standrdX is built for. The governing order is set per project, so an addendum that modifies the specification is applied as the requirement that governs, and the finding shows which document ruled.
Open the finding beside the datasheet. It quotes the line it read and names the document that ruled, so the check takes seconds against the sheet itself. How certain the system is, is shown apart from the verdict.
A findings register with the verdict, severity, clause and evidence on every entry, and the reviewer disposition recorded against each one. It exports to PDF and Excel for sign-off.

Bring a vendor datasheet and the standard that governs it, and compare what standrdX returns against what your own review found.
