At SRT Plastics, we provide the engineering expertise and high-performance materials required to meet IK Ratings (IEC 62262) for industrial enclosures and protective covers. The IK rating system classifies the degree of protection provided by an enclosure against external mechanical impacts, mapping specific classes to impact energy measured in Joules. Using standardized testing methods defined in IEC 60068, we fabricate transparent windows, machine guards, and doors that are optimized for target classes ranging from IK07 to IK10 (20 Joules of impact energy). By combining precision CNC machining with advanced polymers like Polycarbonate (PC), we help manufacturers ensure their equipment remains durable and compliant in high-stress environments. Every component is supplied with full technical documentation to support your certification process.
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.
