Technical file

Technical file is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Technical file rather than just read about it. In short: A technical file is a set of documents that describes a product and can prove that the product was designed in accordance with the requirements of a quality management system. All products that fall under the scope of the General Product Safety Regulation (EU) 2023/988 (GPSR), including CE-marked products, must have a technical file (also referred to as a Digital Product Passport) that contains information demonstra…

Key takeaways

Technical file belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Technical file to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Technical file from memory before moving on to harder problems.

Reference excerpt

A technical file is a set of documents that describes a product and can prove that the product was designed in accordance with the requirements of a quality management system. All products that fall under the scope of the General Product Safety Regulation (EU) 2023/988 (GPSR), including CE-marked products, must have a technical file (also referred to as a Digital Product Passport) that contains information demonstrating conformity with the applicable safety requirements. The technical file must additionally show compliance with the relevant EU directives and regulations. EU enforcement authorities may request a copy of the technical file for many years after the last product was made. Consumers do not normally have access to the technical file.

Content Under the GPSR, a technical file must be maintained for all consumer products placed on the EU market to demonstrate compliance with general safety requirements. The technical file can be stored on paper or electronically and must ensure long-term availability and accessibility. It typically includes:

General product information: description, type/model, intended use, target user group, materials/composition (bill of materials), photographs or drawings. Labels and instructions for use: safety warnings, multilingual instructions, and manufacturer/importer/EU Responsible Person details, as required under GPSR. Risk assessment and mitigation: analysis of hazards (physical, chemical, electrical, flammability, hygiene, foreseeable misuse, and vulnerable users), severity ratings, and documentation of mitigation measures. Compliance documents: EU Declaration of Conformity (DoC), including manufacturer/importer details, applicable legislation, list of standards applied, date, and signature. Certificates, supplier declarations, and conformity test reports (e.g., EN 71, REACH, RoHS). List of standards applied: harmonised or other relevant European standards supporting conformity. Safety data sheets, toxicological assessment reports, composition sheets, or supplier declarations. All documents must be retained for at least 10 years after the product is placed on the EU market. A single document may serve as an index or overview listing all other documents that constitute the technical file. The full technical documentation must be made available without delay to the competent authorities upon request.

Medical devices The sub-clause 4.2.3 of ISO 13485:2016 requires a manufacturer of a medical device to establish a technical file (medical device file, device master record, design dossier, or device master file). Annex II and III of the EU medical device regulation (MDR) and of the In-vitro Diagnostic Regulation (IVDR) contain an overview of the contents and structure of a technical file, here called Technical documentation.

Worked examples

Example 1 — a first encounter with Technical file

Start with the simplest possible case. Write down what Technical file claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Technical file before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Technical file ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Technical file

In research: Technical file appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Technical file in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Technical file is common in secondary-school and first-year university syllabi. It links to neighbouring topics Quality management, Regulation of medical devices, so understanding it makes those chapters shorter.
In everyday life: Look for Technical file outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Technical file in simple terms?

Why does Technical file matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Technical file?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
