The IK (Impact Protection) rating is a code which is used to measure the durability of a specific fixture and the amount of impact it can withstand. IK ratings help classify products by their resistance to impact (kinetic energy). A fixtures IK rating is important when choosing a fixture based on the environment in which it will be used. Analysing the risk of impact is one component in deciding what fixture to use based on its IK rating. For areas of low risk an IK rating of IK07 and below is normally enough. IK08 and above is recommended for fixtures that bare a potential risk of impact, such as public areas internal and external, schools, construction sites and portable equipment.
