Toe protection caps for safety shoes have to resist a shock energy of 200 joules according to standard EN 20345:2011. Baak utilizes toe caps made of 3 different materials: steel, aluminium and composite.
200 joules is achieved with a weight of 20kg dropping from 1 m height.
Test method (toe protection):
A weight (wedge) with a mass of 20kg drops onto a steel cap from one meter height in order to achieve the test energy of 200 J. The height of the plastilin cylinder (see illustration) during the testing process shall not be below the following minimum remaining height.
|Shoe size||Minimum remaining height in mm|
|up to 36||12,5|
|37 and 38||13,0|
|39 and 40||13,5|
|41 and 42||14,0|
|43 and 44||14,5|
|45 and bigger||15,0|
Steel caps have always been used for safety shoes. They are stable, and their weight is less than 100 grams for size 42.
Aluminium caps are 40% lighter than steel caps. Due to the weaker resistance of aluminium, they are a bit thicker than the steel ones in order to comply with the stability requirements of the standards. They are anti-magnetic.
Composite caps consist of composite materials, which obtain the necessary stability from synthetic resins. They are also 40% lighter than steel caps, and their material thickness is higher than that of steel caps. They enable the production of completely metal-free safety shoes.
