IK ratings classify resistance to external mechanical impacts on enclosures and parts. IEC 62262 maps classes to impact energy measured in joules using standardized hammers defined in IEC 60068. Typical industrial targets are IK07 IK08 IK09 and IK10 which equals twenty joules. We machine clear windows guards and doors that support your target class with documentation.
IK codes run from IK00 to IK10. Each class corresponds to a defined impact energy delivered by a standardized hammer. Industrial covers often target IK07 to IK10 with IK10 equal to twenty joules. The required class is usually set by your product standard or risk assessment.
Share the use case and impact points and we will advise a target and test approach.
Select materials and thickness to limit deflection and edge stress. Use continuous frames or stand offs to support larger spans. Oversize holes slightly and use washers to control stress. Set torque carefully to avoid stress cracking. Validate on fixtures that reflect your mounting and impact locations.
Send drawings and we will highlight reinforcement options that improve the chance of first time pass.
Choose polycarbonate for high impact windows and shields. Choose PMMA when optical clarity is the priority and impact risk is moderate. Use laminate or HPL panels for stiff doors and mounting plates. Anti scratch hard coat can improve durability on clear parts. We cut to size machine and finish parts and include a Certificate of Conformity with your shipment.
