For industrial machinery and factory automation manufacturers

Catch the FMEA failures that delay CE marking and fail customer safety reviews

CE marking, UL listing, and IEC 60204-1 electrical safety audits surface the same FMEA gaps every time: missing Detection controls on high-severity failure modes, broken RPN arithmetic, and vague causes that survive internal review but fail the moment an outside auditor reads them. Specwarden catches all three — automatically.

How it works

Upload your DFMEA

Drop in your spreadsheet — .xlsx, .xls, .csv, or .docx. Specwarden detects AIAG-RPN or AIAG-VDA format automatically. No configuration.

Review runs in under 60 seconds

7 deterministic rule checks run first, then Claude Sonnet reads every row for supplier-blame causes, vague language, and missing rationale.

Why Specwarden for machinery manufacturers

Both

DFMEA and PFMEA review in one tool

Machinery FMEA work typically includes both a design FMEA (for the machine itself) and a process FMEA (for the assembly line or manufacturing process). Specwarden handles both formats and auto-detects which one you uploaded.

$7

per review — no consultant day rate

Bringing in a safety consultant for FMEA review typically runs $1,500–3,000 per day. A PAYG review covers a 200-row FMEA for $7. For pre-submission spot checks and internal reviews, the economics are clear.

Zero

files stored server-side — IP-safe for machinery designs

Your FMEA describes your machine's critical failure modes. Specwarden parses it inside the upload request and immediately discards it. No cloud storage, no training data. Findings stay in your browser.

What Specwarden catches

Missing Detection controls on high-severity failure modes

CE and UL audits flag high-severity rows where the Detection Control column is empty or says "100% inspection" without specifying the detection method. Specwarden catches every Sev 8+ row missing a specific, verifiable detection mechanism.

RPN arithmetic verification — the most common machinery FMEA error

Machinery FMEAs are arithmetic-broken more often than automotive ones — the informal FMEA culture means fewer checks and balances. Specwarden verifies S × O × D = RPN on every row and flags discrepancies immediately.

Vague causes that don't trace to a specific failure mechanism

A cause that reads "mechanical wear" or "operator error" without naming the specific component, material, or tolerance is not actionable. Specwarden flags causes that a safety auditor would reject for insufficient specificity.

Detection masquerading as Prevention in PFMEA

For machinery process FMEAs: "100% torque audit" and "auto-reject at test station" are Detection controls. When they appear in the Prevention column, Specwarden's D-103 check flags the misclassification and explains the CE audit risk.

Questions from machinery manufacturers

Do machinery manufacturers need to use AIAG-VDA?▾
In most cases, no. AIAG-VDA is an automotive supply chain mandate. Industrial machinery manufacturers typically use traditional AIAG FMEA-4 (S × O × D = RPN) or IEC 60812 for reliability analysis. Specwarden fully supports AIAG-RPN format — no AIAG-VDA migration needed unless your OEM customer specifically requires it.
How does Specwarden fit with my ISO 12100 risk assessment?▾
ISO 12100 and FMEA are complementary, not redundant. ISO 12100 is a top-down risk assessment framework for the machine as a system; FMEA is a bottom-up analysis of individual failure modes. Specwarden reviews your FMEA against AIAG criteria — it doesn't replace ISO 12100 but helps ensure your FMEA evidence is strong enough to support your risk assessment documentation.
Does Specwarden replace our safety consultant?▾
No. A safety consultant brings system-level judgment, regulatory interpretation, and on-site observation that Specwarden doesn't model. Specwarden catches the rule violations and arithmetic errors that waste consultant time during formal reviews — so when you do bring in the consultant, you're paying for their expertise, not their error-checking.
Does it work on both DFMEA and PFMEA for machinery?▾
Yes. Specwarden auto-detects DFMEA vs PFMEA format from your column headers and applies the correct check set. Upload your machine DFMEA for design-side checks; upload your assembly process PFMEA for process-side checks including control method classification and reaction plan completeness.

Upload your FMEA — catch the safety-audit failures before CE/UL review.
