| 1 | IEC 60079-0 | General construction, testing, and marking requirements for equipment used in explosive atmospheres. | Confirm the complete Ex marking, permitted ambient-temperature range, gas group, temperature class, and equipment protection level match the installation. | Review the certificate, marking plate, instructions, and certified product configuration. |
| 2 | IEC 60079-1 | Requirements for flameproof enclosures, protection type “d.” | Check that the certified enclosure, joints, fasteners, cable entries, and any specified installation conditions are maintained. | Match the enclosure and accessories to the certificate and installation instructions; do not substitute unapproved parts. |
| 3 | IEC 60079-7 | Requirements for increased-safety equipment, protection type “e.” | Verify that the protection type is permitted for the intended zone and that terminals, clearances, and connection methods follow the certified design. | Check the Ex marking and installation instructions for applicable zone, gas group, and equipment protection level. |
| 4 | IEC 60079-11 | Requirements for intrinsically safe equipment and associated apparatus, protection type “i.” | Confirm that the complete circuit—including any associated apparatus, cable parameters, and installation method—meets the certificate conditions. | Review control drawings and entity or system parameters where applicable; a luminaire alone does not establish circuit compliance. |
| 5 | IEC 60079-14 | Design, selection, and erection of electrical installations in explosive atmospheres. | Ensure the luminaire’s protection type and equipment protection level are suitable for the classified location, and that cable entries and wiring are compatible. | Have the hazardous-area classification and installation design checked by competent personnel. |
| 6 | IEC 60079-17 | Inspection and maintenance of electrical installations in explosive atmospheres. | Plan inspection access and maintenance without compromising flame paths, seals, fasteners, or certified components. | Maintain inspection records and follow the equipment manufacturer’s certified maintenance instructions. |
| 7 | GB/T 3836 series | China’s standards series for equipment and installations in explosive atmospheres, covering general and protection-type requirements. | Check the exact applicable part and edition, product marking, and conformity documentation required for the project and market. | Verify documentation against the relevant Chinese requirements; do not assume that one certificate automatically covers every market. |
| 8 | IEC 60092-306 | Shipboard electrical equipment requirements for luminaires and lighting accessories. | Consider shipboard construction and installation requirements in addition to the explosion-protection requirements for hazardous locations. | Confirm the project specification calls for the applicable shipboard requirements and review supporting test documentation. |
| 9 | IEC 60529 | Ingress protection (IP) classification for enclosures against access, solid objects, and water. | Select an IP rating appropriate to the actual exposure, such as washdown, spray, or outdoor installation; an IP rating does not replace Ex certification. | Check the marked IP rating and test evidence for the supplied enclosure and configuration. |
| 10 | IECEx, ATEX, and hazardous-area marking | IECEx is an international certification system; ATEX equipment requirements apply within the scope of EU Directive 2014/34/EU. | Check that the certificate scheme and marking are accepted for the destination market and suit the area classification. Zone, gas group, temperature class, and equipment protection level must be compatible. | Validate certificate numbers and scope with the relevant issuing or official system, and confirm any special conditions of use. |
