IK Explanation
|
IK Impact Test Schedule The "IK" code is a coding system described in BSEN50102 that indicates the degree of protection provided by an enclosure against harmful mechanical impacts. It is similar to the IP rating system and consists of the letters IK followed by two digits, which indicates the impact resistance. These digits run from "00" (not protected according to the standard) through to "10" which is for an impact of 20 joules. However it is our experience, gained over many years, that this level is completely inadequate to guarantee protection against regular or severe vandalism. For this reason, we test our vandal resistant range well above the low standard, in fact to the very high level of 150 Joules, some 130 Joules above the provisions of the standard. In order to indicate the relative strengths of these products we have extended the IK system as shown in the graph. It can be seen that we have chosen IK16 as the 150 Joule level with additional intermediate levels from IK10, the limit of the standard. Where appropriate the IK levels are shown on the product pages. In general products rated IK16 (150 Joules) are available with our unique Lifetime Guarantee against breakage. The means of testing is the pendulum hammer to EN60068-2-75, which details the apparatus, & method we use to carry out our tests. |
