Playground Safety Surfacing Standards

Playground safety surfacing has requirements, also known as standards, to live up to. Whether you’re a school, council, playground equipment manufacturer or landscape architect, you need to understand the playground surfacing requirements to ensure the safety of your playground is top notch.

So, what are the playground surfacing standards?

The main ones you’ll hear about are BS EN 1177:2018 and BS 7188. BS EN 1177:2018 specifies a method for determining the impact reduction of playground surfacing, defining the Critical Fall Height of the safety surfacing. Whereas, BS 7188 provides additional test methods and performance limits to those in BS EN 1177, for resistance to abrasive wear, slip resistance, resistance to indentation and ease of ignition.

BS EN 1177

BS EN 1177:2018 stipulates that manufacturers should carry out laboratory tests on a flat, rigid concrete. These are concrete base tests. Alternatively, we can test surfacing on a substrate of sufficient mass, density and thickness. Because these substrates would make no significant contribution to the test result.

You cannot meaningfully lab test products combined with natural materials that influence their performance (e.g. soil). Installers cannot use these grass base tests to indicate the performance of the product under other conditions or in other locations. For example, if surfacing is installed and tested on a clay-based soil. In this situation, it is almost certain that a greater critical fall height will be achieved under tests when the base is wet as opposed to when the base has been subject to a dry period.

Have you received a supplier quote for certification for a fall height that sounds too good to be true? They may have done a grass base test. You should always check with your supplier, and ask for proof of certification for concrete tests. This is because these will give the most accurate results. Tests from different companies of similar thicknesses of surfacing will likely achieve different results due to the way the surface has been constructed.

When it comes to playground safety surfacing standards, it is always important to remember to ask your supplier to clarify exactly what ground conditions their product has been tested on. For example, if their test states the mat was tested with a 140mm soil layer and mesh on a grass base, you will need to replicate these conditions on site in order for the grass mats to comply to their certification. This is classed as a composite product. Therefore, the safety surface, alongside all its layers must be tested as a whole in order to comply with BS EN 1177.

BS 7188

BS 7188 provides additional tests for abrasive wear, slip resistance, resistance to indentation and ease of ignition, and the results of these tests must fall within the required limits. The BS 7188:1998 limits are as follows:

Performance requirement

Result required to comply with BS 7188

Resistance to Abrasive wear

Wear Index less than 1.0

Wear ratio between 1.0 and 3.0

Slip Resistance

Not less than 40 when tested wet or dry

Resistance to Indentation

Residual indentation shall not be more than 5.0mm

There shall be no cracking, splitting or perforation around the point at which the load was applied

Ease of Ignition

The surface shall have a ‘low’ radius of effects of ignition

Tensile Properties

Upper wearing layer: Tensile strength shall not be less than 0.4 MPa and elongation at break not less than 75%

Lower unexposed supporting layer (where applicable): Tensile strength shall not be less than 0.1 MPa and elongation at break not less than 25%

Other playground surfacing requirements to consider

Addtionally, changes in levels of surfaces should not present hazard(s) to the users of the area.

When developing your playground, you should also check the Critical Fall Height of the surface. The CFH should be accurate, as stated on the test certificate. Additionally, this should be equal to or greater than the ‘free fall height’ of any playground equipment in the area. Playground equipment manufacturers will often specify the free fall height of their equipment within their brochures.
