Global hazardous area equipment (Ex) certification schemes
Achieve international market access and safety compliance with product certification schemes, including IECEx, UKCA Ex, AS/NZS, and ECASeX, for equipment used in explosive atmospheres.
Global hazardous area equipment (Ex) certification schemes
Meeting the highest safety standards
Electrical and non-electrical equipment intended for use in explosive atmospheres must meet the highest safety standards. With increasing global regulation and heightened scrutiny around explosion protection, manufacturers must demonstrate that their products are safe, reliable, and compliant with international requirements.
Standards and schemes such as IECEx, UKCA Ex, AS/NZS, and ECASeX provide frameworks for verifying product conformity, improving market access, and ensuring operational safety across hazardous areas in industries such as oil & gas, chemicals, mining, and manufacturing.
