Klassifisering av sklimotstand i vernesko
Etter hvert som sikkerhetsstandardene utvikler seg, er det viktig å forstå hvilken innvirkning de har på produktene vi stoler på. Vi snakket med Ejendals' overholdelsesekspert, Sandra Dahlström, om de oppdaterte standardene for sklimotstand i EN ISO 20345:2022-forskriften. Her er hennes innsikt i hva disse endringene betyr for arbeidere som ønsker pålitelig beskyttelse på ulike underlag.
Viktige oppdateringer i den nye EN ISO 20345:2022-standarden
Sandra begynte med å forklare at EN ISO 20345:2022 introduserer endringer som gjør det enklere å forstå hvordan vernesko fungerer under forskjellige forhold, spesielt når det gjelder sklimotstand og spikertrampbeskyttelse.
Spikertrampbeskyttelse
Standarden spesifiserer tre typer merkinger, som skiller mellom alternativer i stål og ikke-metall:
P: Stålinnsats med en testspiker med diameter på 4,5 mm.
PL: Ikke-metallisk innsats, også testet med en spiker på 4,5 mm.
PS: Ikke-metallisk innsats testet med en mindre spiker med diameter på 3 mm.
Stigegrep
Dette er nå en ikke-obligatorisk test, noe som gir litt fleksibilitet alt etter fottøyets tiltenkte bruksområde.
Sklimotstand
Finnes det virkelig en «best»-klassifisering?
En av de viktigste innsiktene Sandra delte, var at det ikke finnes noen «best»-klassifisering for sklimotstand. «Fra et standard-perspektiv var det aldri ment at disse klassifiseringene skulle skape et hierarki av god, bedre og best», forklarte Sandra. I stedet avhenger valget av klassifisering mye av de aktuelle forholdene på arbeidsplassen.
Tidligere klassifiserte EN ISO 20345:2011-standarden sklimotstand i tre kategorier:
SRA: Testet på et flisegulv med såpeløsning.
SRB: Testet på et stålgulv med glyserin.
SRC: Oppfylte kravene til både SRA og SRB.

Under this older standard, SRC might seem like the “best” option, but as Sandra points out, it’s more complex than that.
“An outsole that excels in SRA conditions might not be as effective in SRB conditions, and vice versa. To meet both requirements, some compromises might be made in the design, so SRC approval doesn’t necessarily mean the highest slip resistance in every environment.”
What’s New in EN ISO 20345:2022?
The new 2022 standard has eliminated the SRA, SRB, and SRC classifications to avoid confusion. Instead, slip resistance testing is now a basic requirement, meaning all safety footwear must be tested on ceramic floors with soap solutions without needing a specific marking. However, there is an optional SR test, indicating that the footwear has been tested on a ceramic floor with glycerin, suited for more oily surfaces.
- Mandatory Test (no marking) - Conducted on ceramic floors with soap solution.
- Optional SR Test - Conducted on ceramic floors with glycerin, designed to evaluate the footwear’s performance on oily surfaces.
By incorporating slip resistance as a baseline requirement, the updated standard emphasizes that all certified safety shoes meet a minimum threshold without labeling, making the selection process more straightforward.
Real-World Application: Testing Beyond the Laboratory
Sandra emphasized that while lab-tested slip resistance ratings are helpful, they don’t account for the diverse and unpredictable conditions workers may encounter. “No set of laboratory tests can fully model the wide range of real-life walking surfaces,” she noted. This is why Sandra recommends conducting footwear field trials in the actual workplace environment to assess performance accurately.
A slip-resistant outsole reduces, but doesn’t eliminate, the risk of slipping.
“It’s essential to remember that these ratings indicate potential performance; they aren’t a guarantee. Testing the shoes in the environment where they will be used provides a clearer picture of suitability.”
Conclusion: Choosing the Right Footwear for Your Environment
The EN ISO 20345:2022 update reflects a more holistic approach to safety standards, eliminating the misconception of a “best” slip resistance rating and promoting a focus on the actual needs of the workplace. With slip resistance now a foundational requirement, workers and employers can select footwear with confidence while understanding that some conditions may still require additional trials.
Sandra’s final advice?
“Stay proactive in safety equipment choices. Opt for shoes with slip resistance ratings that align with your specific work environment and, whenever possible, test them on-site to ensure they provide the protection you need.”
