European regulations/standards

A comprehensive guide to regulations/standards to make an informed choice of the right level of protection for you.

Guidance on EN ISO 20345:2022 and EN ISO 20347:2022 standards.

The new EN ISO 20345:2022 and EN ISO 20347:2022regulations/standards have incorporated new specific and additional requirements. Some have been removed or have undergone changes. Here are the new requirements:

PL	Resistance to perforation (nonmetallic insert)
AN	Malleolus protection
PS	Resistance to perforation (nonmetallic insert)
CR	Shear resistance
C	Partially conductive footwear
SC	Toe cap abrasion resistance
A	Antistatic footwear
SR	Slip resistance (on ceramic tile floor with glycerin)
HI	Heat insulation of the bottom of the footwear
WPA	Water penetration and absorption

Most important and significant features in the EN ISO 20345:2022 standard

Slip Resistance (SR)

The previous tests regarding 'SRC' (SRA + SRB) slipping will no longer be used, the regulation/standard provides for a change in the procedure of performing the slipping test under different conditions, called 'SR'

(see table below)

Sole resistance to hydrocarbons

This requirement is optional for all safety ratings. If present you are indicated by FO in marking.

LADDER GRIP - GRIP ON RUNG LADDER (LG)

For better grip on ladder rungs, the sole shall have a construction that meets the requirements of the famice in the regulation/standard with a heel height of at least 10 mm, height of crampons present in the famice of at least 1.5 mm and an area of the famice itself, of at least 35 mm.

Resistance to perforation (P, PL, PS)

P Resistance to perforation with metal insert;

PL Resistance to perforation with non-metallic insert (test performed with Ø4.5mm nail);

PS Resistance to perforation with non-metallic insert (test performed with Ø3.0mm nail).

Water Penetration.

The additional requirement WRU (water-resistant uppers), which describes the water-repellent effect of the upper of the footwear, has been changed to WPA (Water penetration and absorption). The required upper requirements remain unchanged.

Toe abrasion resistance (SCUFF CAP)

A "Martindale" abrasion test of 8,000 cycles is prepared in order to determine toe abrasion; the toe shall not develop holes throughout its thickness.

Le Calzature per uso professionale a Norma EN ISO 20345:2011 sono contraddistinte da una “S” (dall’inglese Safety = Sicurezza) come Calzature di Sicurezza. La scarpa cosiddetta “di base” è marcata con le lettere “SB” (S = Sicurezza - “B” = Base). Questa Calzatura deve avere i seguenti requisiti minimi: • altezza del tomaio • puntale (lunghezza minima, base portante minima) • tomaia in pelle “crosta”, microfibra e similare • fodera anteriore • sottopiede • suola in qualsiasi tipo di materiale, può essere liscia • il tomaio, nella calzatura bassa, può essere aperta nella zona del tallone. Nelle Calzature “SB” non sono mai comprensivi i seguenti requisiti se non specificati dettagliatamente: • antistaticità • assorbimento di energia del tacco • impermeabilità dinamica del tomaio • suola con tasselli • fodera posteriore • tomaio idrorepellente • lamina o tessuto antiforo. Vi indichiamo qui di seguito il significato della timbratura che potrete rilevare su

	Condition A (heel slip inclined 7° toward the front)	≥0,31
	Condition B (heel slip inclined 7° backward)	≥0,36

SYMBOL	Test conditions	Coefficient of friction
SR	Condition A (sliding of the heel inclined 7° toward the front)	≥0,19
	Condition B (heel slip inclined 7° backward)	≥0,22

The slip resistance of the footwear has been tested under laboratory conditions. Additional testing by the user under the conditions present in the workplace may provide additional information. Field testing of the footwear is recommended to assess suitability for work.

Safety footwear EN ISO 20345:2022+A1:2024 and EN ISO 20347:2022+A1:2024: Work shoes conforming to this regulation/standard and marked '+A1:2024' attest to adaptation to the latest technical specifications related to upper breathability. This update, identified by Addendum A1:2024, introduces updated requirements and test methods aimed at ensuring improved performance in terms of comfort and moisture management for the user.

Specifically, footwear marked '+A1:2024' has passed upper breathability tests that verify:
- Water vapor permeability, measured in mg/cm²h, according to updated test methods.
- The water vapor coefficient, which evaluates the ability of the upper material to disperse sweat, according to updated test methods.

The inclusion of this marking ensures that the manufacturer has made the necessary changes to the production process and materials used, in range/assortment with the latest breathability standards.

Notified bodies issuing certificates of conformity to work shoes are required to verify compliance with the above.

ESD: dissipative footwear, SUITABLE FOR EPA ENVIRONMENTS

These footwear are designed to allow continuous and controlled dissipation within safe values, of electrostatic charges present on the operator's body in order to protect electronic devices sensitive to electrostatic phenomena. The recommended value of resistance to ground "EPA" is ≤ to 3.5x107Ω. Consi dering that measurements are taken with the footwear worn by the user, the values obtained may vary significantly from person to person and according to environmental conditions since the electrical resistance of the human body is variable.
