Taking into account the level of risk covered, the Regulation defines the PPE categories and determines the various manufacturer’s obligations:
PPE category 1: Protection against minor risks.
PPE category 2: All PPE that are not category 1 or 3.
PPE category 3: Protection against disability or fatality

THE REGULATION (European Union)

Its objective is to develop test methods and requirements in the form of standards defining the technical specifications of products. Some of them, mostly requirements standards, are harmonised with
EU Regulation 2016/425. Compliance with these harmonised standards gives an assurance of compliance with the requirements of EU Regulation 2016/425


• Category 1 PPE: Evaluation of conformity by the manufacturer (Module A)

• PPE category 2 and 3: EU type examination of the PPE (Module B) by a notified independent body for which compliance (with Regulation EU 2016/425) is verified using standards that are in accordance
with the regulation. Issuance of the EU Type Examination Certificate (confidential document).
• PPE category 1, 2 and 3: CE marking on the product.
• PPE category 3: Control by a notified independent body that ensures compliance of the manufacture with the examined PPE:
- either monitoring of conformity to the type based on the internal control of production and supervised controls of the product at random intervals (Module C2),
- or conformity to the type based on quality assurance of the production method (Module D).
• PPE category 1, 2 and 3: Writing by the manufacturer of the EU Compliance Declaration which proves the compliance of the PPE with Regulation EU 2016/425 to the distributor and the market
enforcement authorities.
The product sheet, the user instructions and the Declaration of Conformity are available online on our website: www.deltaplus.eu

EN ISO 20471


This standard specifies the requirements for protective clothing aiming to signal the presence of the wearer visually, so that he may be detected and seen in hazardous situations, in all conditions of daylight, and night under illumination of car headlights.

There are three classes of high-visibility clothing. Each class must have minimum surfaces of visible material constituting the garment; the higher the class, the more visible the garment:


  Class 3 Class 2 Class 1
Background material (Fluorescent) 0,80 m² 0,50 m² 0,14 m²
Retroreflective material (Bands) 0,20 m² 0,13 m² 0,10 m²


Marking : 

X : Class of high visibility surface (from 1 to 3)

EN ISO 20471  

Max. 25x

EN ISO 20471

2 : Class of hight visibility surface (from 1 to 3)

Max. 25x : Optional marking, number of maximum washes authorized for the model. On this example: 25 washes maximum (see indication of service temperature on the garment tag).


This standard specifies the requirements and test methods for non ventilated protective clothing against radioactive contamination in the form of particles.

Clothing of this type is designed only to protect the body, the arms and the legs of the wearer, but it may be used with accessories that protect other parts of the wearer’s body (for example, boots, gloves, respiratory protective device - APR).

The garments are classified according to their nominal protection factor (ratio between the concentration of test particles in the ambient atmosphere and the concentration of test particles inside the garment), determined in relation to the total inward leakage (ratio between the concentrations of test particles insider the garment and inside the test chamber).


The classes are as follows:

3 500
2 50
1 5




This European Standard specifies requirements for materials and the design of protective electrostatic dissipation clothing used in conjunction with a grounded system in order to prevent incendiary discharges. WARNING: These requirements may be insufficient in oxygen enriched flammable environments. This standard is not applicable for protection against mains voltages.

The control of undesirable static electricity on the person is often necessary.

The electrostatic potential may, indeed, have serious consequences on the charged individual, because it can be high enough to cause dangerous sparks.

After a risk assessment, the wearing of protective electrical dissipation clothing may be necessary. The use of clothing certified according to EN1149-5 is then adapted.

The ATEX Directive 1999/92/EC, in its Annex II-A-2.3, requests that workers be equipped with work clothes made of materials that do not produce electrostatic discharges that can ignite
explosive environments.

The electrostatic potential can also affect equipment sensitive to electric discharge. Antistatic clothing is often used on electronic manufacturing sites, assembling semiconductors for example. Finally, they are used on sites with controlled atmospheres such as automotive paint workshops, to avoid the emission of particles that may be deposited on the body paint.

The antistatic charge dissipation can be provided by a process limiting the build up of charge, or by adding carbon or metal wires. People wearing protective electrostatic charge dissipation clothing must always be grounded with a resistance of less than 10⁸Ω, for example, by wearing appropriate footwear such as the safety shoes stated in EN ISO 20345, or by other suitable means.

EN 14058


This standard specifies the requirements and performance test methods for protective garments (vests, jackets, coats, trousers) against cool environments.

These garments are for use in moderate low temperatures (-5°C and over) to protect against local body cooling. Not only for outdoor use such as in the construction industry; may also be used for indoor activities, such as in the food processing industry.

These garments are not always necessarily made of air impermeable or watertight materials.

Therefore, in this European standard, these requirements are optional.

X : Class of heat resistance, Rct

X : Class of air permeability, AP

X : /cler of the garment (Optional)

X : Class of resistance to water penetration WP (Optional)
