ISO 17100 Compliant Translation Services – What It Means for Your Project
In the translation industry, ISO 17100 is the gold standard. It is the international benchmark that separates professional translation providers from casual language service vendors. But what does ISO 17100 actually mean for your project? And why should you care whether your translation provider is compliant?
This article explains ISO 17100 in practical terms, what it requires of translation companies, and how it benefits clients who need accurate, reliable translations for legal, medical, technical, and business purposes.
What Is ISO 17100?
ISO 17100:2015 is the international standard for translation services. It specifies requirements for all aspects of the translation process, including:
- Translator qualifications and competencies
- Project management workflows
- Quality assurance and review procedures
- Client-provider communication and feedback
- Data security and confidentiality
- Subcontracting and supply chain management
Unlike generic quality certifications, ISO 17100 is specific to translation. It was developed by the International Organization for Standardization (ISO) with input from translation industry experts worldwide, including the American Translators Association (ATA), the European Association of Translation Companies (EUATC), and other professional bodies.
Key Requirements of ISO 17100
Translator Qualifications
ISO 17100 requires that translators meet at least one of the following criteria:
- A recognised degree in translation, linguistics, or a related field plus two years of professional translation experience
- A recognised degree in any other field plus five years of professional translation experience
- Five years of full-time professional translation experience (for languages where formal training programmes are not widely available)
Translators must also demonstrate competence in the subject matter of the texts they translate. A translator working on legal documents must have legal translation expertise; a medical translator must have healthcare domain knowledge. This requirement ensures that your project is assigned to someone who understands your field, not just the language pair.
Revision by a Second Linguist
One of the most important requirements of ISO 17100 is that every translation must be reviewed by a second qualified linguist before delivery. This revision step involves comparing the source and target texts to ensure accuracy, completeness, and adherence to project specifications. It is your safeguard against errors, omissions, and mistranslations.
Many non-compliant providers skip this step entirely, relying on a single translator or automated tools. The result is significantly higher error rates and inconsistent quality. At Nepali Linguists, our ISO 17100 compliant process ensures every translation undergoes independent review before you receive it.
Project Management
ISO 17100 requires translation companies to assign a qualified project manager to each project. The project manager serves as your single point of contact, coordinates the translation team, monitors progress, and ensures deliverables meet specifications and deadlines. This structured approach to project management reduces miscommunication and keeps projects on track.
Clear Client Communication
Under ISO 17100, translation companies must:
- Provide clear information about services, pricing, and delivery timelines
- Document project specifications, including purpose, target audience, and formatting requirements
- Maintain records of client feedback and complaints
- Implement corrective actions when issues arise
These requirements ensure transparency throughout the engagement and establish clear channels for communication and feedback.
Data Security and Confidentiality
ISO 17100 includes requirements for handling client data and documents. Translation companies must implement procedures to protect confidential information, including secure file transfer, access controls, and data retention policies. For clients handling sensitive legal, medical, or commercial documents, this requirement provides essential peace of mind.
How ISO 17100 Requirements Map to Translation Workflow
Understanding how ISO 17100 translates into day-to-day operations helps you evaluate whether a provider genuinely follows the standard or merely claims compliance:
| ISO 17100 Requirement | What It Means in Practice | How to Verify |
|---|---|---|
| Translator qualification records | Provider maintains documented evidence of each translator’s education, experience, and domain expertise | Ask about translator screening and qualification documentation |
| Source text analysis | Every project begins with analysis of the source text to identify subject matter, terminology, formatting, and special requirements | Ask how they handle documents with unusual formatting or specialised terminology |
| Translation production | Qualified translator produces the initial translation following project specifications | Confirm that the assigned translator has relevant subject-matter expertise |
| Revision (mandatory) | A second qualified linguist compares source and target texts and makes corrections | Ask about their revision process and whether all projects receive independent review |
| Client feedback and corrective action | Provider has documented processes for receiving, investigating, and responding to client feedback | Ask how they handle complaints or quality concerns |
| Subcontractor management | If the provider subcontracts work, subcontractors must also meet ISO 17100 requirements | Ask whether work is performed in-house or subcontracted |
ISO 17100 vs. Other Certifications
| Standard | Scope | Relevance to Translation |
|---|---|---|
| ISO 17100 | Translation services specifically | Directly applicable – covers translator qualifications, revision, project management, and quality assurance |
| ISO 9001 | General quality management | Broadly applicable but does not address translation-specific requirements like translator qualifications or bilingual revision |
| ISO 27001 | Information security management | Relevant for data security but does not cover translation quality |
| EN 15038 | Translation services (predecessor to ISO 17100) | Superseded by ISO 17100; similar requirements |
The Cost of Non-Compliance: What Happens Without ISO 17100
Choosing a translation provider that does not follow ISO 17100 exposes your projects to several categories of risk:
Quality risk: Without mandatory revision, translations may contain undetected errors in terminology, grammar, or formatting. These errors can lead to rejected applications, non-compliant submissions, or miscommunication in critical settings.
Accountability risk: Non-compliant providers may lack documented quality processes, making it difficult to identify the source of errors or implement corrective actions. If a translation is rejected by a regulatory body, you may have no recourse with the provider.
Compliance risk: For regulated industries, using a non-certified translation provider may itself be a compliance issue. Healthcare providers subject to HIPAA, pharmaceutical companies following GxP guidelines, and legal firms bound by court rules may be required to demonstrate that their translation partners meet recognised quality standards.
Reputational risk: A high-profile translation error can damage your organisation’s reputation. Legal briefs, marketing materials, and patient communications that contain translation errors reflect poorly on your attention to quality and detail.
The premium paid for an ISO 17100 compliant provider is typically a small percentage of total project cost – often 10-20% above non-certified alternatives. Against the potential cost of error remediation, application refiling, legal liability, and reputational damage, this premium represents exceptional value.
How ISO 17100 Compliance Benefits Your Project
Consistent Quality Across Projects
ISO 17100 compliance means every project follows the same rigorous process, regardless of language pair, subject matter, or project size. Whether you need a single birth certificate translated or a multi-volume legal brief, you can expect the same level of quality and attention to detail.
Reduced Risk of Errors
The mandatory revision step significantly reduces the risk of errors reaching the final deliverable. With two sets of expert eyes on every translation, mistakes in terminology, grammar, formatting, and date conversion are caught before you receive the document. This is particularly important for high-stakes projects like certified document translation for USCIS submissions, where errors can result in application rejection.
Accountability and Recourse
ISO 17100 compliant providers maintain documented quality records and have defined processes for handling client feedback and complaints. If an issue arises, you have clear recourse and a structured process for resolution. This accountability is often absent when working with non-certified providers.
Confidence for Regulated Industries
For clients in regulated industries – healthcare, legal, pharmaceutical, finance – ISO 17100 compliance demonstrates that your translation partner meets internationally recognised standards. This can be important for audits, regulatory submissions, and compliance with industry-specific requirements like HIPAA or GxP.
What ISO 17100 Does NOT Cover
It is equally important to understand what ISO 17100 does not address:
- Interpreting services: ISO 17100 applies to written translation only. Interpreting has its own standards, such as ISO 20228 for legal interpreting and ISO 13611 for community interpreting.
- Machine translation post-editing: The standard assumes human translation. While it can be applied to post-editing workflows, it does not specifically address MT output.
- Specific subject-matter certification: While the standard requires subject-matter competence, it does not certify translators in specific domains. Domain expertise must be verified separately.
How to Verify ISO 17100 Compliance
Genuine ISO 17100 compliance requires certification by an accredited certification body. When a provider claims ISO 17100 compliance:
- Ask for their certificate and note the certification body and certificate number
- Verify the certificate covers the specific services you need
- Check that the certification is current (ISO certifications are typically valid for three years with annual surveillance audits)
- Contact the certification body if you have doubts about authenticity
