The marking of galvanic isolators as "Ignition Protected" meets the requirements of which standard?

The "Ignition Protected" marking on galvanic isolators indicates compliance with SAE J1171, which is a standard that deals specifically with electrical devices used in marine applications. This standard sets forth requirements for devices to prevent ignition of flammable vapors, ensuring safety in environments where explosive gases may be present.

Galvanic isolators play a crucial role in marine electrical systems by preventing galvanic corrosion while allowing for safe AC electrical connections. By meeting the SAE J1171 standard, these isolators demonstrate their ability to operate safely without posing a risk of igniting flammable materials, which is essential in the dynamic and potentially hazardous environment of a marine setting.

The other options represent different standards that do not directly relate to the ignition protection for electrical devices in marine applications. For instance, UL 310 pertains to requirements for an electrical circuit protection device, ISO 9001 focuses on quality management systems, and IEC 60335 deals with the safety of electrical appliances for household and similar use. None of these address the specific requirements necessary for ignition protection in marine applications like SAE J1171 does.
