SAFETY

All our products are designed, manufactured and tested against the BS EN 12572 - 3 standard: Artificial climbing structures. Safety requirements and test methods for climbing holds. This standard sets out a set of test methods and design criteria that certain holds (above 100g) must adhere to - and ours do! Although there is no set standard for holds weighing less than 100g, we still stick to similar design methods, and all of our products are manufactured from the same high quality toughened Polyurethane Resin & Coffee mixture, and are all finished to the same level of detail and attention.

What does the standard involve? There are two main tests, and a sample preparation procedure that go as follows:

Firstly: Submerge the hold in water, then freeze at -30°C for an hour, then heat at +70°C for an hour. This cycle of submerging in water, freezing and heating is done 5 times in total. Assuming no defects are caused in this process by water expanding and cracking the part - it’s onto test 1.

Resistance to fixation: This involves putting half a tonne of force through the bolt hole, without the part being fixed to a wall - instead, being placed on two steel rods, meaning that the hold  must be able to withstand the back blowing out, and also not suffer any bending issues. (Regardless of passing this test - make sure you only ever fix your holds to a flat secure surface!)

Structural integrity: Here the hold must be able to withstand 2.4Kn (240KG) loaded straight down in the most “unfavourable position” whilst fixed securely to a wall.

All our products are certified following the instructions set out in BS EN 12572 - 3. We were able to measure the temperatures with a digital data logger, and utilised a hydraulic press to apply and measure the loads required in the two tests. 

If you’re wanting to certify some holds yourself, and don't want to shell out on a press and a super duper cold freezer, drop us a line at contact@kneebarclimbing.com and we’ll see if we can help!
