Approvals for work and safety footwear

Sika Footwear’s work footwear is certified according to the European standards for safety footwear (EN ISO 20345:2011) and work footwear (EN ISO 20347:2012). In 2022, new, official certifications in both categories were issued. Both approvals will be valid in a transitional phase. The overviews below show the differences between the new and old approvals.

Safety footwear approvals

EN ISO 20345:2011 - the old approval

Footwear certified in accordance with EN ISO 20345:2011, has, at minimum, a toe cap to protect from falling objects at 200J and compression (15kN).
This basic certification is also known as 

Additional protection can also be added to the footwear. The most common combinations are:

Certifications of the sole’s slip resistance properties

EN ISO 20345:2011 - the old approval

The soles of the shoes are tested for their anti-slip properties and can be approved at different levels. 

The outsole is slip tested and approved on ceramic tiles with a soap solution.

The outsole is slip tested on a steel plate with glycerine 

The outsole is slip tested to SRA and SRB. 

Other approvals on EN ISO 20345:2011 - the old approval

Fuel and oil resistance: Approved oil and fuel resistant outsole. 
Heat-resistant outsole: Heat-resistant outsole, up to 300 °C for one minute 

Heat insulation of outsole: Approved heat-insulating outsole. 
Cold insulation of outsole: Approved cold-insulating outsole. 

Safety footwear approvals

EN ISO 20345:2022 - the new approval 

Footwear certified in accordance with EN ISO 20345:2022, has, at minimum, a toe cap to protect from falling objects at 200J and compression (15kN).

Certifications of the sole’s anti-slip properties

EN ISO 20345:2022 - the new approval

In the new standard, the SRA test is mandatory when it comes to the anti-slip properties of the sole. 

The new SR approval is optional and is obtained if the sole passes the test. 

The outsole is skid tested on ceramic tile with a glycerin solution.

Other approvals on EN ISO 20345:2022 - the new approval 

SC: Scuff Cap: Strong ProNose approved for work involving kneeling.

LG: Ladder Grip: Footwear with ladder grip approved for use on ladders. 

FO: Fuel & Oil resistance: Approved oil- and fuel-resistant outsole. 
HRO: Heat Resistant Outsole: Approved heat-resistant outsole that can withstand up to 300°C for one minute. 
HI: Heat Insulation of Outsole: Approved heat-insulating outsole. 
CI: Cold Insulation of Outsole: Approved cold-insulating outsole.
WR: Water Resistance: Approved waterproof footwear. 
WPA: Water Penetration and Absorption: Approved water-resistant upper. 

Safety footwear: The differences between EN ISO 20345:2011 and EN ISO 20345:2022 

You have to watch your step when you want to get an overview of the differences between the new and old certifications of safety footwear. 

The main difference between the old (EN ISO 20345:2011) and the new (EN ISO 20345:2022) certification is: 

  • Protective midsole: P
    • EN ISO 20345:2011 does not distinguish between the type of protective midsole and only tests on large nails. 
    • EN ISO 20345:2022 distinguishes between metal and non-metal protective midsoles and tests on two seam sizes: Large (L: 4.5 mm) and small (S: 3 mm). 
  • Slip resistance: SR 
    • EN ISO 20345:2011: tests and approvals according to SRA, SRB and SRC. 
    • EN ISO 20345:2022: The SRA tests are mandatory in the new standard and are sufficient to achieve certification, so it no longer gives any designation. SR is a voluntary extra designation you can get, and it only appears if you do extra tests. The test simulates slip resistance on oil/grease surfaces. 
  • Scuff Cap Abrasion (ProNose approval): SC
    • EN ISO 20345:2011: Does not test the ProNose 
    • EN ISO 20345:2022: Tests whether the shoe’s ProNose can be certified to be extra durable and thus approved to withstand work involving kneeling. If the ProNose is approved, the shoe will be designated SC. 

Approvals of work footwear 

EN ISO 20347:2012 - the old approval 

Work footwear is approved according to EN ISO 20347:2012. This certification means that the footwear is without toe protection and approved for professional use. 
This basic authentication is called  

Additional protection can also be added to the footwear. The most common combinations are:

OB + A + E
Antistatic sole (ml. <0.1 MΩ - 1000 MΩ) + Shock absorption in the heel, min. 20J
OB + A + E + WRU
Antistatic sole (ml. <0.1 MΩ - 1000 MΩ) + Shock absorption in the heel, min. 20J + Water repellent upper
OB + A + E + WRU (only applies to waterproof boots)
Antistatic sole (ml. <0.1 MΩ - 1000 MΩ) + Shock absorption in the heel, min. 20J + Water repellent upper

EN ISO 20347:2022 - the new approval 

Den forskel, der gør sig gældende for Sika Footwear på den nye og den gamle godkendelse, er tilføjelsen af O6-godkendelsen: 

OB + A + E
Antistatic sole (ml. <0.1 MΩ - 1000 MΩ) + Shock absorption in the heel, min. 20J
OB + A + E + WRU
Antistatic sole (ml. <0.1 MΩ - 1000 MΩ) + Shock absorption in the heel, min. 20J + Water repellent upper
OB + A + E + WRU (only applies to waterproof boots)
Antistatic sole (ml. <0.1 MΩ - 1000 MΩ) + Shock absorption in the heel, min. 20J + Water repellent upper

OB + A + E + WR
Antistatic sole (ml. <0.1 MΩ - 1000 MΩ) + Shock absorption in the heel, min. 20J + Water repellent shaft
