===Optional additional tests===
Manufacturers can submit their boots for six optional extra tests. [[Motorcycle News]] noted that "Manufacturers can also request that their boots are subjected to additional tests in order to receive further accreditation." These tests include 'IPA' for ankle or shin protection, 'WR' for water resistance or 'WAD' for the displacement of water from inside.<ref>Hayzelden, J. (2023) 'The best motorcycle boots', ''Motorcycle News'', 18 May. Available at: https://products.motorcyclenews.com/clothing/clothing/best-motorcycle-boots/. (Accessed: 19 June 2023)</ref> Passes in these tests will be represented on the label with letters underneath the mandatory test ratings.

'''IPA/IPS – Impact protection to the ankle and/or shin:'''
These show boots with approved impact protection. For this test, the boot is cut along the sole and opened up; a striker is used to drop 10 joules of force onto the protector. To pass this test, the protector can't allow more than 5kN to be transmitted through it. If the ankle protection passes, the letters IPA will be on the label, and shin armour will be displayed as IPS.

'''WR – Resistance to water penetration:'''
Boots that claim to be water resistant should be tested in one of two ways. They can be clamped to a machine with the toes flexing to replicate 4600 steps while the foot is submerged in water, or a person can wear the boot and walk 1km (100 x 10-metre lengths) in shallow water. To pass in either method, areas of dampness inside the boot can be no bigger than 3cm².

'''FO – Resistance to fuel and oil on sole:'''
Two samples of a boot are weighed twice – once normally and once in distilled water. The sample is then left soaking in fuel at 23 degrees for 22 hours, taken out and weighed in the same ways again. To pass, the weight of the samples shouldn't increase by more than 12%.

'''SRA/SRB/SRC – Slip-resistance of sole:'''
Three tests make up the one rating for slip resistance. Each test is done with a mechanical heel set at a seven-degree angle, which moves to imitate different kinds of slips and falls on different surfaces. If the label shows ‘SRA’, the sole will have passed on a ceramic tile surface treated with diluted soap. ‘SRB’ means it passed on a steel floor treated with glycerol. ‘SRC’ means the boot passed both tests.

'''B – Breathability of uppers:'''
If a CE label has the letter B on it, it means the boot has gone through an optional test to check that moisture vapour can escape.

'''WR – Water absorption/desorption of inner:'''
The boots are tested to see how much water the insides hold and how much they release. If the boots pass this test, ‘WAD’ will be displayed on the label.
