The New Standards for Safety Footwear Explained
Reason for changes
The changes are driven by the need for the safety testing to mirror real life working scenarios while making some tests more precise. Developments in footwear materials since the last standard also required attention. Some aspects of EN 20345:2011 remain unchanged including their appropriate safety codes.
What are the Key Changes?
Slip Resistance
Under the new standards, SRA, SRB and SRC will disappear. Linked to Health & Safety statistics which highlight slips as the dominant insurance claim for industrial work, slip resistance has become a mandatory test with a minimum standard to meet. There is no code for this minimum slip performance. If the minimum slip performance cannot be met, this must be disclosed.
There is an additional higher standard of slip resistance which can be tested for but this is not mandatory. This new safety code is SR.
Slip Testing will no longer feature a steel surface. Instead, both mandatory and additional slip testing is being carried out on a ceramic tile surface. The mandatory test will use sodium lauryl sulphate for its lubricant; the optional enhanced SR test will use glycerine for its lubricant.
The final change to the slip resistance standard is the area of the footwear tested. To mirror real life movement, the heel and forepart is the areas of focus and no longer the flat of the footwear.
Anti-Penetration Midsoles
Due to the continued growing consumer demand for non-metallic specification the standards have considered the variation in quality of non-metallic midsole offering. Accordingly, for non-metallic midsoles only, two new tests apply:
- PL (Large) – uses a 4.5 millimetre 'nail' for general safety working risks.
- PS (Small) – uses a 3 millimetre 'nail' for environments with greater perforation risk (e.g. factory floors with fine sharp shrapnel).
For metallic midsoles there is no change in testing or standard level currently applied ISO 20345: 2011. The P code will be used for metal midsoles. Brands cannot show PL and PS for the same product.
Anti-Scuff Toe Protection
In the new standard, the testing subjects the scuff toe protection to 8,000 abrasion cycles. On achievement of this standard the product can add SC to the safety specification.
Ladder Grip Test
The change covers the waist area of the outsole, its angle, the cleat design and heel breast dimensions. The code LG will be added to the product specification should the sole meet the new Ladder Grip Standard.
New Water Resistance Symbols
The old symbol of WRU (Water Resistant Upper) has been replaced by a new code WPA (Water Penetration and Absorption). In addition, WR may be used for water resistance footwear which uses a waterproof membrane.
Ankle Protection
There is a minor update with regards the dimensions of the ankle area for testing. Buckbootz continues to drive ahead of the market and standards by certifying protection and support for both outer and inner ankle areas. The new standard makes inner ankle protection (AN) optional.
