"Does your grass mat surfacing conform to the standard?" is a question that we get asked quite often by new customers
And honestly, it’s a question that all buyers should be asking when it comes to safety in playgrounds. If you’re new to the world of grass mats, you might have a whole host of questions related to the grass mat standard, which we’ve helpfully answered here! (If you have more questions, feel free to leave a comment, or email us at firstname.lastname@example.org or call us on 01564 742811)
What is the grass mat standard?
The British Standard, better known as BS EN 1177 (2018), specifies a method for determining the impact reduction of playground surfacing. It defines a “Critical Fall Height” for surfacing, which represents the upper limit of the surface’s effectiveness in reducing head injury.
What do the tests involve in order to meet this standard?
Testing provides a method for assessment of safety surfaces. In accordance with EN 1177 (2018), test specimens are struck with an instrumented headform from a series of different drop heights.
The instrumented headform measures impact energy to determine the head injury criterion (HIC) and peak acceleration (gmax). The certificated Critical Fall Height is the lowest drop point that produces a HIC value of 1,000 or a gmax value of 200.
Are there different types of tests?
What if the product is part of a system?
Our SmartPlay product is installed as part of a system, with a few different variations available. For products such as our SmartPlay shock pads that are intended to be laid over another layer, the entire system must be tested. This is classed as a composite product and the surface with all its layer(s) must be tested as a whole to BS EN 1177 (2018).
Always remember to ask your supplier to clarify exactly what ground conditions their product has been tested on. For example, if the 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.
With regard to the construction of the Grass Safety Matting we recommend you use a supplier that offers a minimum 5‐year guarantee on its product, can provide a flammability test certificate and can supply spares and support if problems arise in the future.
