Direct Answer
EN ISO 21420 is the general requirements standard for protective gloves. It addresses requirements such as glove design, ergonomics, harmlessness, sizing, and marking. It is used alongside the specific standard applicable to the hazard the glove is intended to protect against; it is not a substitute for that hazard-specific standard.
The purpose of this reference is to explain what EN ISO 21420 covers, what buyers should look for, and how to interpret it without confusing general glove requirements with protection against a particular hazard.
01 — Scope
What Does EN ISO 21420 Cover?
EN ISO 21420:2020, Protective gloves — General requirements and test methods, establishes general requirements for protective glove design and construction, harmlessness, comfort and efficiency, marking, and information supplied by the manufacturer.
EN ISO 21420 is a general framework, not a complete test specification for every hazard. Its scope does not address the protective properties of gloves, so it is used together with the appropriate specific standard or standards.
What It Covers
- General glove design and construction
- Harmlessness and relevant test methods
- Comfort and efficiency
- Sizing and fit-related requirements
- Marking and manufacturer information
What It Does Not Establish
EN ISO 21420 does not, by itself, establish that a glove protects against a particular mechanical, chemical, thermal, or other workplace hazard.
That protection must be assessed under the relevant specific standard.

General Requirements vs. Specific Standards

Practical meaning: A glove may meet general requirements while still being unsuitable for a particular task. The buyer must match the glove’s intended use and specific protective performance to the actual hazard.
02 — Ergonomics
Ergonomics: Fit, Comfort and Glove Efficiency
Ergonomics is important because protective gloves must allow the wearer to perform the intended task effectively.
EN ISO 21420 addresses comfort and efficiency as part of its general requirements. In practical glove selection, this means considering how the glove fits, how it supports movement, and whether it is suitable for the intended duration of use.
Fit
The glove should be appropriate for the wearer’s hand dimensions. A suitable fit supports practical use and comfort.
Dexterity
The design should support the movements needed for the task, especially where handling and precision matter.
Comfort
The glove should be suitable for the intended duration of use and should not create unnecessary discomfort.
Construction
Seams, materials, and other design features should support the glove’s intended function.
Important distinction
These considerations should not be confused with a specific hazard rating. A glove can be comfortable and well-fitting without providing the required protection against a particular risk.
03 — Harmlessness
Harmlessness: Materials and User Safety
Harmlessness concerns whether the glove, when used normally, presents an unacceptable risk to the wearer.
EN ISO 21420 includes requirements relating to innocuousness and the relevant test procedures. The standard addresses the materials and construction of protective gloves, including considerations relevant to user safety.
Materials
Consider the materials used in the glove and whether they are suitable for the intended application.
Construction
The glove should not introduce unnecessary risks through its materials or construction during normal use.
Intended Use
Review the glove’s intended use and the manufacturer’s information about relevant materials and limitations.
Skin Considerations
Material selection can matter where users may be exposed to substances that cause skin irritation or allergic reactions.
Important
EN ISO 21420 is not a blanket guarantee that every wearer will have no allergic reaction. Buyers should consider the glove’s materials, intended use, and any relevant manufacturer information.
04 — Sizing
Sizing and Fit
Correct sizing is a core part of glove usability. EN ISO 21420 includes requirements for sizing and general glove efficiency.
A practical sizing process
- Measure the hand according to the manufacturer’s sizing guidance.
- Compare the measurement with the glove size chart.
- Check the intended task. A glove for precision work may require a different fit preference from a glove for heavy-duty handling.
- Confirm comfort and movement. The glove should not restrict the hand unnecessarily or interfere with the task.
Why sizing matters
A glove that is too tight may restrict movement or become uncomfortable. A glove that is too loose may interfere with handling and reduce practical efficiency.
The appropriate size depends on both the wearer’s hand and the glove’s design.

Buyer tip: Ask the supplier for the actual size chart and the intended fit. Do not assume that the same nominal size will fit identically across different glove constructions.
05 — Marking
Marking and Manufacturer Information
EN ISO 21420 includes requirements for marking and information supplied by the manufacturer.
For buyers, marking and accompanying information are important because they help identify the glove and understand its intended use and relevant protection claims.
Product Identification
The glove should be identifiable through its marking and product information.
Manufacturer Information
Confirm the manufacturer’s identity and the information supplied with the glove.
Intended Use
Review the manufacturer’s information about the glove’s intended application.
Relevant Protection Information
Check the applicable specific standard and protection performance claims.
The exact marking and information requirements should be checked against the applicable version of the standard and the relevant product requirements. Do not assume that a general glove marking alone proves compliance with every specific protective requirement.
06 — Standards Relationship
How EN ISO 21420 Relates to Specific Standards
EN ISO 21420 is designed to work with specific standards that address particular protective properties.
EN ISO 21420 provides general requirements. The specific standard must be selected according to the actual hazard and the protective property required.
| Standard / Topic | What It Addresses | What Buyers Should Check |
|---|---|---|
| EN ISO 21420 | General glove requirements and test methods | General design, construction, harmlessness, comfort, efficiency, marking, and information |
| Specific mechanical protection standard | Protection against defined mechanical hazards | The relevant mechanical protection claims and test results |
| Specific chemical protection standard | Protection against defined chemical hazards | The chemicals, permeation or degradation performance, and intended use |
| Specific thermal protection standard | Protection against defined thermal hazards | The relevant thermal protection claims and test results |
| Other applicable standards | Other defined protective properties | The standard applicable to the actual hazard |
Note: This is a conceptual comparison. It does not replace the specific standard or its detailed requirements.
EN ISO 21420 vs. EN 388
EN ISO 21420 and EN 388 serve different purposes. EN ISO 21420 provides general requirements, while EN 388 is a specific mechanical protection standard.
EN ISO 21420 vs. EN ISO 374
EN ISO 21420 does not replace the specific standard for chemical protection. Chemical protection claims must be supported by the applicable specific requirements and documentation.

07 — Buyer Guidance
What Should PPE Buyers Ask a Glove Supplier?
The most useful procurement questions connect general requirements to the actual product and application.
- What is the glove’s intended use?
- Which specific protective standard applies to the hazard?
- What general requirements are addressed under EN ISO 21420?
- What materials and construction are used?
- What sizing information is available?
- What marking and manufacturer information is supplied?
- What specific test reports or certification documents are available?
- What limitations should the buyer understand?
- Can the supplier provide product-specific technical information?
Why this matters for OEM and private-label buyers
For OEM and private-label projects, the general requirements should be considered during product development, not only after production. Material selection, construction, fit, intended use, and marking should be aligned with the product’s intended protective function.
