EN Clothing Types Compared to OSHA Protection Levels

EN standards define 5 “Types” of application-based chemical protective clothing. But what do they mean and how do they differ from North American OSHA protection levels?

For a global business looking to standardize PPE in every regional base the need to meet multiple local standards and conventions is a challenge. When managing hazardous chemicals in the workplace an understanding of the differences between regions can be useful. This blog aims to explain the chemical protective clothing Types defined by EN standards, the OSHA Protection Level guidance used in North America, and to show where they are different or similar.

EN Standards for Types of Protective Clothing

The system launched in the European Economic Community in 1995 aimed to improve the levels of protection against workplace hazards by introducing a legal requirement that all PPE should meet minimum performance requirements. This was achieved through the publication of standards for PPE performance, with compulsory compliance being independently audited and approved by appointed “Notified Bodies”, and indicated on PPE labels by the now well-known CE mark.

CE with stars white no backgroundThe CE mark on PPE is an indication it is certified to EN standards. Yet there are many fake products in the market place – especially outside Europe in regions where CE is increasingly used. Often such product looks certified, but isn’t. How do you know? Our blog here looks at how to identify properly CE marked PPE.

For chemical protective clothing several CE standards define performance requirements according to the hazard; it’s state: liquid, dust, or gas, and in the case of liquids: light aerosol, liquid, or jet sprays. These define 5 “Types” of clothing according to level and type of protection provided.

 A Notified Body is an organization appointed  by an EU member government to audit specific types of PPE according to relevant standards and to issue a CE certificate based on that audit.

For Safety Managers it is useful to know that certification and all required testing is conducted independently of the manufacturer.

Meanwhile in North America no such mandatory or optional standards exist for chemical protective clothing. However, OSHA, the Occupational Safety & Health Administration, the government agency charged with “ensuring safe and healthful conditions for workers” has issued four “Protection Levels” as guidance for choosing PPE for protection against hazardous materials in the workplace.



The PPE or the Hazard? An Important Difference

A key difference between the approaches of Europe and America is that whilst European chemical suit standards focus product – in this case clothing that protects the skin of the wearer, with respiratory and ingestion hazards dealt with by other standards, the protection levels in America address whole body protection including, and treating as primary, protection against respiratory hazards. Thus, the OSHA levels address all the required PPE, considering respiratory protection as paramount, whilst the EN standards have different standards for different PPE.

(This distinction between product and hazard is also seen in other protection types. For example, the EN standard for fire fighters clothing, EN 469, defines requirements only for clothing, with other fire-fighters PPE being addressed by separate standards. In North America however, the equivalent NFPA 1971 standard considers requirements not only for clothing but also for helmets, gloves, boots and so on. It’s title refers to “…protective ensembles…” for fire-fighters rather than “fire-fighters’ clothing”.

This means direct comparison of the EN standards and OSHA protection levels is difficult; there are no direct equivalents. However, below is an analysis of both and a summary of how they compare.


EN Standards for Chemical Resistant Protective Clothing

In EN standards all PPE is classified as follows: –

Category IProducts designed to protect against minimal hazards
Category IIIntermediate products that are neither category I nor III
Category IIIProducts designed to protect against hazards that may cause serious injury or are a threat to life
Note: All clothing for protection against hazardous chemicals is classed as Category III. Lightweight, breathable, single layer and low cost spunbonded polypropylene coveralls are NOT considered protective clothing as they offer little in the way of protection other than against dirt. Such garments are classed as Category I PPE.


The key standards for chemical protective clothing are: –

Type 6EN 13034: Clothing for protection against light aerosol sprays of liquids
Type 5EN 13982: Clothing for protection against Hazardous Dusts
Type 4EN 14605: Clothing for protection against liquid (shower-type) sprays
Type 3EN 14605: Clothing for protection against liquid jet sprays
Type 1EN 943: Gas-tight Clothing for protection against gases and vapours. (This is sub-divided into parts 1 and 2, with Part 2 being clothing for Emergency Teams and featuring additional requirements)


Originally there were 6 TYPES, Type 2 being included in EN 943 and being air-fed “non-gas tight” clothing. However, this was rarely used and commonly misunderstood, so was withdrawn in the 2015 version of EN 943

Garments certified to either one or more of these standards must display the specific pictogram below to indicate “chemical protection” on the label.

chemical protective clothingHowever, in addition many manufacturers also use the pictograms shown in the table below to indicate the Type of clothing. Note that these Type-specific pictograms are not required by the standards but are a convention adopted by many, though not all, manufacturers. Some prefer to use their own symbols. The standards do, however, require the “Type”, standard number and date is referenced on garment label.

How is Chemical Resistant Clothing Tested?

The process for certification of clothing to these standards includes three types of testing:-

Tests assessing the physical properties of garment and construction. 

Abrasion Resistance
Flex Cracking Resistance
Tensile Strength
Trapezoidal Tear Strength
Puncture Resistance
Seam Strength.

Test methods for each are given in separate referenced test standards with the results of each classified as 1 to 6 (6 being the highest). Classifications are defined in tables in the reference standard EN 14325.

Tests for resistance of the fabric against either penetration or permeation of liquids or gases.

Resistance to Penetration / Repellency test for Type 6 garment fabric (EN ISO 6530)

Assesses the ability of a fabric suspended at 45o to resist penetration of four specific liquids, identifying a percentage for both penetration and repellency and classifying each as 1 to 3 (3 being the highest) with minimum performance requirements.

Resistance to Permeation of chemicals for Types, 1,3 and 4 garment fabric (EN ISO 6529)

Assesses resistance against permeation of chemicals. The standard for Type 3 and 4 does not define any specific chemicals, but those tested are dictated by the application. The standard also requires at least one test with a minimum class 1 result on a “seams exposed in use”.

The Type 1 standard for gases and vapors however specifies 16 chemicals that must be tested on fabric, seam and components such as visor and gloves and with minimum performance requirements.
see note below

“Type” tests on the whole finished garment. 

The testing that defines the difference between the clothing Types is primarily the “Type Test” on the whole garment. The principle for each is the same: –

  • A test subject of appropriate size for the test garment dons a sample
  • A series of exercises designed to simulate a normal working environment are conducted to ensure it does not tear or damage in normal conditions
  • The test subject enters a spray cabin and either: –
    • In the case of Type 5 the cabin is filled with dust particles (Sodium Chloride of various particle size)
    • In the case of Types 6, 3 and 4 the subject is sprayed with liquid according to the protection Type.
  • The subject emerges from the cabin and in each case an assessment of any penetration of dust or liquid inside the suit is made.
  • A pass or fail result is given according to specific criteria.
It is important to recognise that permeation test results, given as a “breakthrough time” and classified as 1 to 6 (6 being the highest), do not indicate when the chemical first “breaks through” the fabric. The result is intended to be used for comparison of fabrics, not to indicate a garment is safe to wear. You can discover more about this here.


The test and assessment criteria for each Chemical Protective Clothing Type is shown below: –

Type 5: Type Test for Clothing for Dust Protection

Type 5 test graphic-1

  • The test subject stands on a treadmill and performs three “movements” during the test: walking, squatting and standing still.
  • Three sensors inside the suit measure particles that penetrate, whilst a fourth outside in the cabin produces a “challenge count”.
  • Using this information calculations of “Inward leakage” are made for each sensor and during each movement.
  • Pass or fail is defined according to specific criteria for the inward leakage.

It is worth noting that a pass does NOT mean no penetration has occurred. Allowance is made for some penetration of the dust.

Protection against Hazardous Liquid Chemicals

For Types 3,4 and 6 liquid protection, the test subject wears a white, absorbent coverall underneath the test garment. Because this stains easily it acts as an indicator of penetration. The liquid used is is water and is the same in each test: –

  • Its surface tension is lowered using a surfactant. This increases its tendency to wick through any small holes in the garment construction so making the test more challenging.
  • It is died red so that any staining of the absorbent under-garment will be apparent.

Type 6: Type Test for Clothing for Liquid Aerosol Protection

Type 6 test graphic

  • The test subject stands on a turntable that rotates once in one minute
  • As the turntable rotates, the subject makes an exaggerated walking motion. This ensures exposure of the liquid to all parts of the garments
  • Four nozzles at a distance of 1.5M from the center of the turntable spray the garment with an aerosol of the test liquid for one minute as the turntable rotates.
  • The garment is then allowed to drain for two minutes and carefully removed.
  • The total area of any staining of the indicator garment of three tests is measured and a pass or fail calculated
How is pass or fail assessed in the liquid protection Type Tests?

In the Type 6, 4, and 3 liquid spray tests the assessment of pass or fail is the same.

Three garment samples are tested. Using the liquid from the test, 5 microliters are dripped from a height of 5cm onto a clean section of one of the undergarment samples and left for one minute. The area of the stain it creates is measured and serves as the “calibration stain”.

After testing three garments, the total area of all staining on all three indicator garments is measured. For a pass, the total stain area must be less than three times the area of the calibration stain.

Whilst complex, this method does ensure the result is directly related to the conditions of the  test on the day, accounting for variations in atmospheric pressure or liquid surface tension, rather than to some benchmark parameters which may not be always replicated accurately. It is also worth noting that a pass does not mean the there has been no penetration as some is allowed. This might be important for applications involving highly toxic chemicals.
