The footwear standard ISO 20345:2011 has now been updated to ISO 20345:2021
Here's a breakdown of what's changed:Slip Resistance
Water Resistance Markings
Scuff Cap Abrasion Resistance Test
Puncture Resistance Changes
Ankle Protection Test Update
"S" Ratings Compared
Slip resistance - The old SRA, SRB & SRC test and markings have now been replaced.
The old test was to be based on the sole of the footwear meeting the following:
- Slip resistance on ceramic tile floor with NaLS (SRA if passed)
- Slip resistance on steel floor with glycerine (SRB if passed)
- Slip resistance on ceramic tile floor with NaLS and on steel floor with glycerine (SRC if passed)
The new standards show that all footwear must now meet a slip resistance (equivalent to SRA) as standard, and an optional test can be performed to add the new "SR" marking (equivalent to SRC).
The new tests are no longer performed on a steel floor, now both tests are performed on a ceramic tile surface with the mandatory test performed with Sodium Lauryl Sulfate (NaLS) as it's lubricant, and the SR test will feature glycerine as it's lubricant.
These new tests include the head and forepart as well as the sole of the boot within the test area.
A marking of "⌀" can also be shown if the footwear can't be tested. (e.g footwear has studs or spikes)
The old symbol of WRU (water resistant uppers) will now be replaced with WPA, which stands for Water Penetration and absorption.
The test is mostly the same, except the dimensions in the positioning of the shoe and the use of absorbent paper.
This new requirement will test the durability of the scuff cap to establish it's capability in protecting the toe cap.
A symbol of "SC" will be shown if the footwear passes a test of 1000 abrasion cycles.
This new marking will be measured to fire-fighter standard and if suitable will show the new "LG" marking.
There are 2 new test methods for NMAPI (non-metal anti-penetration inserts).
The first test for general risks will be a 4½mm diameter nail, and if passed the footwear will be marked "PL".
The second test for higher risk will be a 3mm diameter nail, and if passed the footwear will be marked "PS".
Either of the above tests can be chosen by the manufacturer but only one of the markings can be given per style.
If a style offers a steel plate insert, the footwear will be marked with a "P" as per the 2011 standards.
The area of the footwear tested has been updated to include the specific location of the protection, instead of a general location across all styles.
