In short

A standard that actually tests translators.

DIN EN ISO 17100 is the only international standard written specifically for translation service providers. It defines who may translate (qualification), how every translation is checked (revision by a second person — the four-eyes principle), which resources and terminology management a provider must maintain, and how an order is documented from enquiry to delivery.

Fachübersetzungsdienst GmbH, operating internationally as termbase, is registered with DIN CERTCO for translation services to DIN EN ISO 17100 under registration no. 7U517 — publicly verifiable in the DIN CERTCO register. What the standard actually requires, how we implement it, and where it reaches its limits, follows below.

The standard

What DIN EN ISO 17100 actually requires.

From selecting the translator to free-of-charge correction — these requirements of the standard accompany every order at termbase, not just a sample.

Translator qualification

Only someone who can show a recognised translator qualification and relevant professional experience translates subject-matter texts for us.

Four-eyes principle

Every translation is checked against the original by a second, equally qualified specialist — no translation leaves the house unrevised.

Terminology & resources

Terminology databases, translation memories and documented work instructions secure consistency across projects and years.

Project management

From the quote to delivery, every step — deadlines, queries, approvals — is documented and traceable.

Correction

If a defect is identified within the agreed scope, we correct it free of charge — the standard requires a defined complaints process.

Order handling

A clearly defined sequence from enquiry, quote, order confirmation to delivery — traceable for you and for the register.

The standard is the minimum. Not our ceiling.

DIN EN ISO 17100 mandates qualification, four-eyes revision and terminology management — foundations our team has lived for more than 20 years regardless.

Quality guarantee

Our commitment — clear, no small print.

Free correction on formal complaint. If an authority, a court or you yourself raise a formal objection to a translation within the agreed scope, we correct it free of charge. That is not goodwill — it is the complaints process DIN EN ISO 17100 requires, and one we document as we go.

The commitment rests on four-eyes revision: every specialist translation is checked against the source text by a second, equally qualified person before it leaves the house. Combined with the binding fixed price, you know in advance what you get — and what it costs. See the fixed price →

Technology & AI at termbase

Cutting-edge technology — and knowing where the specialist is irreplaceable.

Machine translation and AI produce fluent sentences in seconds today. Where they are reliable, we use them; where meaning is at stake — numbers, negations, liability — the specialist translator decides. That line is drawn not only by caution but by the revision requirement of DIN EN ISO 17100.

What technology does for you: we have worked with CAT tools, translation memories and terminology databases for decades. They keep terminology consistent across projects and years, speed up the work, make previously translated content reusable and so lower your costs. Neural machine translation (NMT) and AI are one more tool for us — embedded in the controlled, DIN EN ISO 17100-revised process, never a substitute for it.

Where the standard draws a clear line: raw MT output plus light post-editing falls outside the scope of ISO 17100:2015 — the standard describes human-performed, revised professional translation. A text that only runs through a machine and gets a quick read-through afterwards is not a compliant, authority-recognisable certified translation. For machine-pre-translated texts there is a dedicated, managed path: post-editing (MTPE) to DIN EN ISO 18587.

Where AI brings speed and where the specialist decides Two columns. Left: tasks where AI and automation bring speed — repetitions and TM matches, large uniform volumes, a first rough draft, consistent boilerplate. Right: tasks the specialist owns — numbers, negations and obligations, law, medicine and safety, tone, register and idiom, the certification statement and liability. AI & automation bring speed The specialist decides Repetitions & TM matches Large, uniform volumes First rough draft in seconds Consistent boilerplate Cost advantage on repetition Numbers, negations, obligations Law, medicine, safety Tone, register, idiom Certification statement & liability Sign-off on the final version
Not an either-or: the machine handles repetitions, large volumes and the first rough draft; the specialist makes the sensitive calls — checked under the four-eyes principle before the text leaves the house.

Where the limits lie — and why we know them

Six documented weaknesses of machine translation — from fluently worded factual errors to invented terminology. We name them openly, because our process is built to catch exactly these points.

Fluent ≠ correct

NMT produces grammatically fluent sentences that can be factually wrong — fluency over content precision. These fluent-but-wrong errors slip past laypeople and automated metrics easily.

Errors where it matters most

Inaccuracy sits exactly where it is critical: numbers, negations, obligations — negated contract clauses, dosages, reversed safety warnings. The last percentage points are the most dangerous.

Hallucinations

AI sometimes produces plausible-sounding but invented content — especially with technical terms, unusual phrasing or a sparse source. Without a check, it goes unnoticed.

Terminology drift

Without control, the same word gets translated differently across segments and pages. Our terminology databases and translation memories keep the naming consistent.

Not certifiable

Pure AI output is not a translation that carries ISO 17100 accountability or legal recognisability — it lacks human responsibility and the certification statement.

Fuzzy matches — checked

Suggestions from the translation memory that only approximately fit (fuzzy matches) are checked by us against context, not adopted blindly.

Fluency versus content accuracy: raw AI translation compared with specialist review Schematic bar comparison without a numeric axis. On fluency, raw AI translation and the version after termbase specialist review are both high. On content accuracy, raw AI translation reaches only a medium level, while the version after termbase specialist review is high. The accuracy gap is closed by the specialist. high low raw AI translation after termbase specialist review high high Fluency / readability medium high Content accuracy this gap is closed by the human
Schematic, without concrete measured values: raw AI translation reads as fluently as a reviewed version — but on content accuracy, a gap remains that only specialist review closes. That is exactly what our four-eyes process targets.

Our position

We use machines and AI as a tool — inside the revised process, never as its replacement. Every certified translation ultimately carries the review and accountability of a qualified specialist translator to DIN EN ISO 17100, not a model. More on our professional translations and our fixed price.

Our auditor asked who had translated a 2023 revision and against which glossary. termbase answered both from its own records the same day. You only find out whether that part of a quality system exists at the moment somebody asks.

FAQ

Quality & DIN EN ISO 17100 — frequently asked questions.

What does DIN EN ISO 17100, Reg. 7U517 mean?

DIN EN ISO 17100 is the international standard for translation service providers; it governs translator qualification, revision by a second person, terminology management and order handling. The termbase is registered under registration no. 7U517 with DIN CERTCO (TÜV Rheinland Group) — publicly verifiable in the DIN CERTCO register.

Is registration to DIN EN ISO 17100 a legal requirement?

No. The standard is voluntary; no law requires translation providers to register. The termbase undergoes it voluntarily, as external proof of processes the team already lives day to day.

What does the standard require for translation services within its scope?

Five core areas: the translator's qualification, revision by a second, equally qualified specialist (the four-eyes principle), terminology and resource management, documented project management, and a defined process for correction on complaint.

Is pure machine translation compliant with the standard?

No. Raw MT output plus light post-editing falls outside the scope of ISO 17100:2015 — the standard describes human-performed, revised professional translation. Machine translation alone is not enough for a certified translation that authorities will accept.

Does termbase use artificial intelligence and machine translation?

Yes — as a controlled tool. We have worked with CAT tools, translation memories and terminology databases for decades; we use AI and neural machine translation where they add speed and consistency. Content accountability stays with the specialist: every professional translation is revised under the four-eyes principle of DIN EN ISO 17100. For machine-pre-translated texts there is a dedicated path — post-editing (MTPE) to DIN EN ISO 18587.

Why isn't raw AI translation enough for critical texts?

Because machine translation sounds grammatically fluent even when it is factually wrong. Errors cluster exactly where it is most sensitive — numbers, negations and obligations — and can appear as plausible-sounding but invented wording (hallucinations). Only a specialist checking against the source text catches such fluent-but-wrong errors. That is why pure AI output is not a certified, authority-recognisable translation.

How can I verify the registration myself?

Directly in the public DIN CERTCO register under registration no. 7U517: it shows the registrant, the standard and the validity in the original.

What happens if an error still occurs?

The standard requires a defined complaints process: if a defect is identified within the agreed scope, we correct it free of charge.
