Under Regulation (EU) 2016/425, PPE Categories I, II and III classify the risk against which a product is intended to protect. They are not quality grades. Category I is limited to five groups of minimal risk; Category II covers risks not listed in Categories I or III; and Category III is limited to risks that may cause death or irreversible damage to health. The category determines the conformity assessment route and the level of notified-body involvement.
This distinction matters because products with similar names can follow different routes. A glove intended only for weak cleaning products is not assessed in the same way as a glove claiming protection against hazardous chemicals. The product category must align with the claimed protective function and be supported by the exact model’s technical documentation, marking, and conformity evidence.
This guide uses the current consolidated text of Regulation (EU) 2016/425 available when checked in August 2026 and the European Commission’s PPE Regulation Guidelines, 5th edition, October 2025. It is general information rather than legal advice for a specific model or market decision.
What Do PPE Categories I, II and III Mean?
The three categories describe the seriousness and type of risk covered by the PPE. Article 18 of Regulation (EU) 2016/425 requires PPE to be classified according to the risk categories in Annex I.
The category belongs to the intended protection, not simply to the product family. A helmet, glove, boot, garment or pair of glasses does not receive a category because of its name. The manufacturer must first define the intended use and protective claims, identify the relevant risks, and then determine which Annex I category applies.
Three related ideas should be kept separate:
- PPE category determines the conformity assessment route under the regulation.
- Performance level or protection class describes tested performance under an applicable standard or technical specification.
- Workplace risk assessment determines whether the PPE is suitable for a particular task, hazard and user.
A higher category therefore does not mean better workmanship, greater comfort or a higher score. It means that the PPE is intended to protect against a risk assigned to a more demanding regulatory route.
PPE Categories I, II and III at a Glance
The regulation uses two closed lists and one residual category. Category I contains only the minimal risks listed in Annex I. Category III contains only the listed risks capable of causing very serious consequences. Category II covers the risks left between those two lists.
| Category | Risk scope under Annex I | Examples that may fall in the category | Conformity assessment route |
| Category I | Only the five listed groups of minimal risk | Simple protection against weak cleaning materials, prolonged water contact, non-extreme weather or superficial injury | Module A: internal production control |
| Category II | Risks not listed in Category I or Category III | Many mechanical-impact, cut, abrasion, eye, head and footwear hazards that are neither minimal nor Category III | Module B EU type-examination, followed by Module C |
| Category III | Listed risks that may cause death or irreversible damage to health | Fall arrest, harmful noise, hazardous substances, oxygen deficiency, electric shock, drowning and other listed serious risks | Module B, followed by Module C2 or Module D |
These examples are only for orientation. The exact category depends on the product’s intended protective function and claim scope. It should be confirmed from the risk assessment, technical documentation and applicable conformity procedure rather than copied from a generic product table.
What Is Category I PPE?
Category I covers only minimal risks that appear in the exhaustive list in Annex I. A manufacturer cannot place a product in Category I merely because the product looks simple or the expected injury seems unlikely.
The five Category I risk groups are:
- Superficial mechanical injury.
- Contact with cleaning materials of weak action or prolonged contact with water.
- Contact with hot surfaces not exceeding 50 degrees C.
- Eye damage caused by sunlight, other than while observing the sun.
- Atmospheric conditions that are not extreme.
The Commission guidelines give useful context. Superficial injuries include minor scratches, plant pricks or bruises that do not require medical attention. Weak cleaning materials can include diluted surfactants used for ordinary dishwashing where the main protective need is water resistance. Non-extreme atmospheric conditions include normal rain, water splashes and ordinary winter weather encountered during outdoor activities.
Category I uses Module A, or internal production control. A notified body is not required by that prescribed route. The manufacturer assesses conformity, prepares the technical documentation, draws up the EU declaration of conformity and affixes the CE marking under its own responsibility.
Calling this route “self-certification” can be convenient, but it should not imply that evidence is optional. The manufacturer must still identify the applicable essential health and safety requirements, demonstrate how the design meets them, control production and retain the required records. Testing may still be needed to support the claim even though a notified body is not mandated.
What Is Category II PPE?
Category II is the residual category: it covers risks that are not included in Category I or Category III. The regulation does not provide a closed Category II product list, and it does not formally define the category as “medium risk.”
Many familiar industrial PPE products are Category II when their claimed protection concerns hazards such as mechanical impact, abrasion, cuts or similar risks that are neither minimal nor among the Category III list. Depending on the exact claim, this can include industrial safety helmets, mechanical protective gloves, safety spectacles and safety footwear.
Those examples are not universal classifications. Safety footwear intended for an electrical risk, a glove intended for hazardous chemicals, or a product combining several protective functions may follow a different category. The claim and risk come first; the product name comes second.
Category II requires EU type-examination under Module B. A notified body examines the technical design and representative specimen and, if the requirements are met, issues an EU type-examination certificate for the identified type. Serial production then follows Module C, conformity to type based on internal production control. The manufacturer remains responsible for ensuring that production matches the approved type and for issuing the EU declaration of conformity.
What Is Category III PPE?
Category III covers only the serious-risk groups listed in Annex I where the consequences may include death or irreversible damage to health. It is not a general label for every demanding workplace.
The Category III list covers risks relating to:
- Substances and mixtures that are hazardous to health.
- Atmospheres with oxygen deficiency.
- Harmful biological agents.
- Ionising radiation.
- High-temperature environments with effects comparable to an air temperature of at least 100 degrees C.
- Low-temperature environments with effects comparable to an air temperature of -50 degrees C or below.
- Falling from a height.
- Electric shock and live working.
- Cuts from hand-held chainsaws.
- High-pressure jets.
- Bullet wounds or knife stabs.
- Harmful noise.
This list explains why respiratory PPE for hazardous substances, fall-arrest equipment and hearing protectors can be Category III. Chemical protective clothing, electrical PPE, life-preserving equipment and chainsaw protection may also fall in Category III when their intended protection matches one of the listed risks.
The temperature wording deserves care. The legal text refers to environmental effects comparable to the stated air temperatures. It should not be reduced to a simple rule that any product tested at one temperature automatically belongs in Category III. The exposure, claimed protection and applicable technical assessment still have to be examined.
Category III requires Module B EU type-examination followed by one of two ongoing production-assessment routes: Module C2, involving supervised product checks at random intervals, or Module D, involving quality assurance of the production process. The CE marking is followed by the identification number of the notified body responsible for the Module C2 or Module D procedure.
Why Can Similar PPE Products Fall Into Different Categories?
Similar-looking products can belong to different categories because the regulation classifies the intended protective risk, not the catalogue name. Gloves provide the clearest example, but the same principle applies to eyewear, footwear and protective clothing.
| Product family | Intended protection example | Likely category direction |
| Gloves | Weak household cleaning products or prolonged water contact | Category I, if limited to the listed minimal risk |
| Gloves | Mechanical cut, abrasion or impact hazards not falling in Category III | Often Category II, subject to the exact claim |
| Gloves | Hazardous chemicals capable of causing very serious health effects | Category III |
| Eyewear | Ordinary sunlight protection, excluding direct observation of the sun | Category I |
| Eyewear | Industrial mechanical hazards or artificial radiation not in Category III | Often Category II, depending on the claim |
| Protective clothing | Non-extreme rain and ordinary weather | Category I where the garment is PPE for that limited risk |
| Protective clothing | Hazardous substances, harmful biological agents or listed extreme environments | Category III when the claimed risk matches Annex I |
The word “likely” matters. A table can explain the logic, but it cannot classify an unidentified product. Borderline cases may depend on exposure conditions, intended users, foreseeable misuse, performance claims and the exact standard or technical specification used.
How Are Multi-Risk PPE Products Classified?
PPE intended to protect against more than one risk is placed in the category corresponding to the highest applicable risk category. This is the approach stated in the European Commission’s PPE Regulation Guidelines.
For example, a glove may claim both mechanical protection that would normally fall in Category II and protection against a hazardous substance listed in Category III. The combined product is treated as Category III. Its conformity assessment and evidence must cover the complete protective claim, not just the easier mechanical part.
Multi-risk products also create a practical scope issue. Different risks may require different technical competence, tests or standards. One notified body may not hold the complete notified scope for every claimed protection. The manufacturer should make sure that all relevant essential health and safety requirements are addressed and that the EU declaration of conformity accurately reflects the full product and assessment route.
How Does the Conformity Route Change by Category?
The conformity route becomes more demanding as the regulated risk category changes, but manufacturer responsibility remains in every route.
Category I: Module A
The manufacturer performs internal production control. No notified body is required by Module A, but technical documentation, an EU declaration of conformity, correct CE marking, traceability and production control are still required.
Category II: Module B Plus Module C
A notified body conducts EU type-examination under Module B. After the type is approved, the manufacturer uses Module C to keep serial production in conformity with that approved type. Module C does not add ongoing notified-body surveillance.
Category III: Module B Plus Module C2 or Module D
The type first undergoes Module B. Ongoing production conformity is then assessed through either supervised product checks under Module C2 or production-process quality assurance under Module D. The notified body’s identification number associated with that ongoing assessment follows the CE mark.
An EU type-examination certificate is therefore only one part of the evidence chain. It does not replace production control, the EU declaration of conformity, correct product marking or the manufacturer’s responsibility for the finished PPE.
Does Category III Mean Better PPE Than Category II?
No. Category III does not mean that a product is automatically stronger, more comfortable, longer-lasting or better made than Category II PPE. It means the claimed protection concerns one of the serious risks listed in Annex I and therefore requires a stricter conformity route.
Product performance must be read from the relevant standard, class, level, marking and test evidence. Two Category II gloves can have different cut or abrasion performance. Two Category III respirators can have different filtration classes and limitations. Category alone does not tell a user which model is suitable for the job.
This is also why category should not replace a workplace assessment. A correctly classified and CE-marked product can still be wrong for a particular concentration, impact energy, temperature, voltage, fall system or user fit.
How Can You Identify the Category of a PPE Product?
The CE symbol alone does not reveal whether a product is Category I or Category II. Both categories normally carry CE marking without a production-surveillance notified-body number. Category III PPE normally carries the CE mark followed by the four-digit identification number of the notified body involved in Module C2 or Module D.
That number is a useful clue, but it should not be used alone. It identifies the body responsible for ongoing Category III production assessment and may not be the same body that issued the Module B EU type-examination certificate.
The most reliable check is to compare the exact model across several sources:
- The intended use and risk claims in the manufacturer’s instructions.
- The PPE category and conformity route stated in the EU declaration of conformity.
- The model or type covered by the EU type-examination certificate for Category II or III PPE.
- Module C2 or Module D evidence for Category III production control.
- Product and packaging markings, including the notified-body number where applicable.
Names, model codes, variants, materials and performance classes should match. A document issued for a similar-looking product is not evidence for an unlisted model.
What Should Be Checked in PPE Compliance Documents?
For a distributor, importer, safety manager or industrial buyer, the useful question is not simply “Does it have CE?” The evidence should form a consistent chain from the stated hazard to the supplied product.
A focused document review should confirm:
- The manufacturer and, where applicable, importer identities.
- The exact model, variant and intended protective use.
- The assigned category and conformity-assessment modules.
- Applicable standard references, editions, classes and performance levels.
- An EU declaration of conformity that identifies the same model.
- A valid EU type-examination certificate for Category II or III PPE.
- Module C2 or Module D notified-body information for Category III PPE.
- Product markings and instructions that agree with the documents.
A laboratory report, voluntary certificate or ISO management-system certificate is not interchangeable with an EU type-examination certificate or EU declaration of conformity. Each document answers a different question. When the product has changed, the current model and variant must remain within the documented approval scope.
What Are the Most Common PPE Category Mistakes?
Most category errors start by classifying a product name instead of its intended risk. The following shortcuts are especially unreliable:
- Treating Category I, II and III as low-, medium- and high-quality grades.
- Assuming every glove, helmet, safety shoe or garment has one fixed category.
- Describing Category II as a closed list rather than the residual category.
- Assuming all heat, cold, chemical or electrical claims belong to one category without checking Annex I scope.
- Using the old Directive’s informal “simple” and “complex” terminology without checking the current regulation.
- Believing that an EN standard or test report by itself decides legal category.
- Expecting a four-digit notified-body number after the CE mark on Category II PPE.
- Ignoring the highest applicable category when a product protects against several risks.
- Transferring a certificate or conformity route from one model or material variant to another.
Classification should be made early enough to guide design, testing and conformity assessment. It should then remain consistent in the technical file, certificate, declaration, instructions, labels and public claims.
Frequently Asked Questions
Are all safety gloves in the same PPE category?
No. A glove limited to weak cleaning materials may be Category I, a mechanical protective glove may be Category II, and a glove protecting against hazardous substances may be Category III. The exact intended protection and evidence determine the category.
Is hearing protection Category III PPE?
Yes, where the intended protection is against harmful noise. Harmful noise is one of the serious-risk groups listed in Category III under Annex I of Regulation (EU) 2016/425.
Does Category I PPE still need CE marking?
Yes. Category I follows Module A without mandatory notified-body involvement, but the manufacturer must still meet the regulation, prepare the technical documentation and EU declaration of conformity, and affix CE marking correctly.
Should Category II PPE show a notified-body number after the CE mark?
Normally no. A notified body performs Module B EU type-examination, but Category II production follows Module C without ongoing notified-body surveillance. The four-digit number after CE is associated with the Module C2 or Module D body for Category III PPE.
Can one PPE product protect against risks in different categories?
Yes. Multi-risk PPE can cover several hazards. The Commission guidelines state that it should be placed in the category corresponding to the highest applicable risk category, while its assessment must address the full protective scope.
Conclusion
PPE Categories I, II and III are risk classifications, not product rankings. Category I is limited to five minimal-risk groups, Category II covers the risks outside Categories I and III, and Category III is limited to listed risks that may cause death or irreversible harm.
The category determines whether the manufacturer follows Module A, Module B plus C, or Module B plus C2 or D. It does not, by itself, prove suitability for a task. Correct selection still depends on the exact hazard, product performance, fit, limitations and consistent model-level evidence.
