Kilonewtons, or more commonly seen as kN, is the force that is applied to the glass balustrade. This is the test where the force is applied and a deflection measurement is taken. In the UK glass balustrade has a deflection limit of 25mm.

1.00kN equates to, rounding up, approximately 102kg

As a general overview the load requirements are as follows:

0.36kN – Internal single-family domestic or external where the drop is less than 600mm
0.74kN – External single-family domestic where the drop is 600mm or greater
1.50kN – Light commercial installations such as bars and restaurants
3.00kN – Heavy commercial installations such as stadiums, airports and stations.
