What is GSO IEC 60335-1?
GSO IEC 60335-1 is the Gulf Standard Organisation (GSO) adoption of IEC 60335-1 — the safety standard for household and similar electrical appliances — as a mandatory requirement for appliances placed on the markets of the Gulf Cooperation Council (GCC) countries: Saudi Arabia, United Arab Emirates, Kuwait, Qatar, Bahrain, and Oman. The GSO version is technically identical to the underlying IEC standard but carries mandatory certification status within GCC member states.
GSO IEC 60335-1:2022 is based on IEC 60335-1:2020 (6th edition) — the current edition. Compatible Electronics is accredited for this standard at Lake Forest, supporting manufacturers seeking GCC market access for household appliances alongside their existing IEC 60335-1 and CE marking test programmes. Since the technical requirements are identical to IEC 60335-1:2020, a single test campaign can support certification for multiple markets simultaneously.
🔎 GCC mandatory certification: The GCC countries require mandatory product certification for household electrical appliances before market entry. The certification authority varies by country — SASO (Saudi Arabia), ESMA (UAE), BIDAA/PAI (Kuwait), QS (Qatar), NQMA (Bahrain), and DGSM (Oman). Testing to GSO IEC 60335-1 at a NVLAP-accredited laboratory like Compatible Electronics supports the test report requirements for these certification programmes. Our EMC Design Consulting team can advise on the complete certification pathway for your product and target GCC market.
Multi-Market Safety Testing
GSO IEC 60335-1:2022 is technically identical to IEC 60335-1:2020. A single test campaign at Compatible Electronics supports certification for multiple markets simultaneously:
✓
IEC 60335-1:2020 is the base standard. Testing at Compatible Electronics to this edition simultaneously supports GSO IEC 60335-1:2022 for the GCC market.
✓
EN 60335-1 EU versions harmonised under the Low Voltage Directive. Compatible Electronics holds accreditation for multiple EN 60335-1 editions at Lake Forest.
✓
SNZ/AS/NZS 60335.1:2022 is also accredited at Lake Forest — GCC and AU/NZ safety testing in the same campaign.
✓
EMC Alongside Safety
Household appliances also require EN 55014-1 (EMC emissions) for EU CE marking and equivalent standards for GCC. Both safety and EMC testing available at Compatible Electronics.
