Technical Localization Services

What our technical localization services deliver beyond translation

A translated document tells the reader what the source said. A localized document tells the reader what to do, in the units, formats, and regulatory frame of the place where they are standing. Our technical localization services exist for that second job. The linguistic work is handled by certified translators who specialize in your field, and around it we add an engineering adaptation layer: measurement conversion, standards mapping, electrical specification checks, date and number formatting, paper size, safety symbol conventions, and local support details.

The distinction matters most in documents that drive physical action. When we are localizing user manuals, a wiring section that references 230 V and 50 Hz is a defect for the US market even if every sentence is grammatically flawless. The same goes for a torque spec in newton meters handed to a technician holding a foot-pound wrench, or a DIN fastener callout in a parts list where the local supplier stocks ASTM grades. We treat these as errors of the same severity as a mistranslation, because the consequence on the shop floor is identical.

Scope-wise, the service covers user documentation, installation and commissioning content, datasheets, training handouts, labeling text, and packaging inserts. Software strings and interface text follow a different pipeline with its own tooling, which we describe on our software localization services page. If your project mixes both, we run the two workstreams in parallel against a shared termbase so the manual and the screen say the same thing.

Units, electrical specifications, and formats: the engineering layer

Unit handling sounds trivial until you do it at scale. Converting 10 bar to 145.04 psi is arithmetic; deciding that the manual should say 145 psi, that a calibration table must keep four significant digits, and that a safety-relief setting cannot be rounded at all is engineering judgment. Our conversion pass distinguishes between descriptive values, where sensible rounding improves readability, and normative values such as tolerances, torque limits, and setpoints, where we convert exactly and flag anything that rounding would push outside its stated band.

Electrical content gets its own check. Grid voltage and frequency statements, plug and receptacle types, breaker ratings, and motor nameplate data are compared against the destination market. A heater rated for 230 V / 50 Hz does not simply become a 120 V / 60 Hz heater because the text changed; when the hardware differs by market, we align the document with the correct SKU and flag mismatches to your engineering contact rather than papering over them.

Item	European source	US deliverable
Pressure	bar	psi, original bar value in parentheses on first use
Temperature	°C	°F primary, °C retained in specification tables
Supply power	230 V / 50 Hz	120 V or 208–240 V / 60 Hz, verified against the US model
Threads and fittings	BSP, metric	NPT and UNC callouts confirmed with the parts list

Date format	31/07/2026	07/31/2026
Page size	A4	US Letter, layout reflowed before delivery

Formats round out the layer: decimal separators, thousands separators, time notation, phone number patterns, and address blocks all switch to the target convention. For documents headed into the US, hazard communication text is checked against OSHA 29 CFR 1910.1200 conventions for signal words and pictogram usage, and drawing callouts follow ASME Y14.5 terminology where dimensioning language appears in prose.

Mapping DIN, EN, and JIS references to ANSI and ASTM

Standards references are where localization earns its keep. A European manual may cite DIN EN 10025 for structural steel, ISO 4762 for socket head cap screws, or EN 60204-1 for machine electrical safety. A US reader works against ASTM A36, ASME B18.3, and NFPA 79. Some of these pairs are close equivalents, some overlap only partially, and some have no counterpart at all.

Our process is conservative by design. Where an equivalence is published and recognized, we cite the local standard alongside the original. Where the overlap is partial, we keep the original reference and add the nearest local standard with a note. Where no equivalent exists, the original stays and the reference lands on an exception list for your engineers. Every substitution is recorded in a standards mapping table delivered with the project, so your compliance team can verify the chain instead of trusting it. In fifteen years of doing this work we have never let a translator silently swap a normative reference, and that policy has survived every audit a client has thrown at it.

The same discipline applies in reverse for US manufacturers exporting to Europe or Asia, and it extends to the certification marks and declarations mentioned in text: UL, CSA, CE, and PSE statements describe different legal facts and are never treated as interchangeable labels.

Choosing the right locale: es-MX, es-419, fr-CA, and their neighbors

Every project starts with a locale decision, and we refuse to make it by default. Spanish is the clearest case. Mexican Spanish (es-MX) matches trade vocabulary used by technicians in Mexico. European Spanish (es-ES) reads foreign on a Monterrey factory floor. Latin American Spanish (es-419) is a deliberately neutral register that serves multi-country distribution at the cost of some local color. Which one is right depends on your installed base, your distributor network, and occasionally on a regulator: import documentation for a specific country should follow that country's usage.

French splits the same way. Canadian French (fr-CA) has distinct terminology preferences and, in some sectors, legal drafting conventions that differ from fr-FR; Quebec workplace documentation in particular follows local usage that a Parisian translator will not produce naturally. Our French technical translation teams are staffed separately for the two variants, and the same is true for the Spanish pairs on our Spanish page. At kickoff we review where the equipment ships, who provides after-sales support, and what your existing content already uses. The decision goes into the account style sheet, and every later project inherits it, which is how you avoid a documentation library that drifts between variants over the years.

The 12-point localization checklist we apply to every job

Each deliverable passes a named checklist before release. Reviewers sign each point, and the signed checklist ships with the files.

1. Units of measure converted, with rounding rules applied by value type
2. Electrical specifications verified against the destination grid and the correct product variant
3. Standards references mapped, with a delivered exception list for unmapped citations
4. Date, time, number, and currency formats set to the target locale
5. Page size and layout adjusted, including reflow for text expansion
6. Safety signal words and symbols aligned with the governing convention (ANSI Z535 or ISO 3864)
7. Warranty, liability, and regulatory statements flagged for client legal review
8. Support contacts, addresses, and phone formats localized
9. Graphics text and callouts extracted, translated, and reinserted
10. Reading direction and script-specific typography handled where applicable
11. Locale variant confirmed against the account style sheet
12. Terminology validated against the client termbase, deviations logged

The checklist is not decoration. Point 2 alone has caught wiring diagrams that referenced the wrong market variant in three separate projects, and point 7 routinely surfaces warranty periods that legal never intended to offer abroad.

How the work moves through our shop

Delivery follows an ISO 17100-compliant process, which in practice means defined roles and a revision stage that is never optional. A project manager audits your source files and builds a localization kit: termbase extract, style sheet, locale decision, unit and standards rules. Translation is done by a specialist in your subject area working into their native variant. A second, independent linguist then revises the full text against the source, and a technical reviewer runs the 12-point checklist. Nothing ships on a single pair of eyes, whatever the deadline.

One project illustrates the flow. A European HVAC manufacturer came to us with 40 installation guides for its US market entry. The linguistic volume was modest; the adaptation load was not. Refrigerant line sizing appeared in millimeters, wiring sections assumed 230 V single-phase, and fitting callouts were BSP throughout. Our reviewers converted line sizes to inch designations, aligned the electrical sections with the 208–230 V / 60 Hz US models, rewrote fitting references to NPT after confirming the US parts list, and flagged two guides whose hardware had no US variant yet. The client's support team later told us the flagged guides would have generated field failures if published as translated. Companies in that position can read more about how we serve HVAC equipment makers on the dedicated industry page.

Quality you can measure: SAE J2450

Opinions about translation quality are cheap, so we score it instead. SAE J2450 is a quality metric originally developed for automotive service information and now used well beyond it. A reviewer samples the delivered text, tags every error against seven defined categories, from wrong term and omission to punctuation, weights each as serious or minor, and normalizes the total by word count. The output is a number, comparable across languages, vendors, and releases.

On continuing accounts we report the score with every major release and track the trend. A rising score triggers a root-cause review before it becomes a client complaint. The metric also gives procurement something concrete to write into an SLA: a maximum normalized score, a sampling method, and a remedy. We are comfortable signing up to that, and we put the method in the statement of work so both sides measure the same way. As a member of ATA and GALA, we also benchmark our scoring practice against what the wider industry publishes, from our base in Texas with coverage across all US time zones.

What technical localization costs and how we quote it

Localization is quoted as translation plus named engineering tasks, never as a vague premium. The linguistic portion is priced per word, with translation memory discounts applied to repeated and previously translated segments. On top of that, the quote itemizes conversion and verification work, standards mapping, layout adjustment, graphics text handling, and the checklist review, each as its own line. Typical projects land 15 to 30 percent above a plain translation of the same files, and the itemization lets you see exactly where that difference comes from and trim tasks your own team wants to keep in-house.

Two cost behaviors are worth knowing in advance. Specification-dense documents such as datasheets carry more adaptation cost per word than prose procedures, because nearly every line contains a value that needs a decision. And the second language into a market is cheaper than the first, because the locale decisions, mapping tables, and rules created for the first language are reused. Clients localizing into four or five markets see the engineering line items shrink steadily after the pilot language.

Where this service gets used the most

The heaviest users are equipment manufacturers moving product across the Atlantic in either direction. For manufacturers, the typical package is a manual set plus datasheets plus labels, localized as one batch so values stay consistent across documents. Commissioning content is the other frequent case: our installation guide translation team handles the documents where a wrong unit does the most damage, since installers act on them directly with the equipment in front of them.

Beyond those, we localize training handouts for plants standing up production lines abroad, packaging and compliance inserts, and field service bulletins that go out mid-lifecycle. If the document type you need is not listed here, browse the full list of our services, or send us the files and we will tell you which pipeline fits. For certification needs attached to localized documents, our certified technical translation service issues signed accuracy statements that reference the localized deliverable.
