Deep fat fryers and similar appliances (fried-food fryers) handle high-temperature cooking oil, and oil-temperature control with overflow prevention is at the heart of safety. Ningbo Xuntong Standard provides a systematic reading of IEC 60335-2-13 (with the national equivalent GB 4706.13) to help businesses lock down oil-temperature and overflow risks at the design stage.

1. Applicable standards and scope

IEC 60335-2-13 covers deep fat fryers and similar frying appliances, with the equivalents GB 4706.13 and the EU’s EN 60335-2-13. Because high-temperature cooking oil is involved, overflow prevention, splash prevention and oil-temperature limits are emphasised beyond the general requirements.

2. Oil-temperature control and overflow prevention

Oil-temperature limits and overflow devices (float/limiter) are the focus; abnormal tests verify that when the limiter fails, the appliance does not overheat or splash. Ningbo Xuntong Standard recommends a “dual limiter + overflow redundancy” design so that even if the main limiter fails, the backup protection can still cut the heating.

3. Structure and other items

Handle strength, frying-basket locking, accessible-surface temperature rise and heat resistance of non-metallic materials must all be met. Unreliable handle fixing and accidental basket ejection are common mechanical non-conformities, and Ningbo Xuntong Standard recommends organising the structural review to strengthen these points.

4. What Ningbo Xuntong Standard can do for your business

Ningbo Xuntong Standard can provide pre-testing, non-conformity diagnosis and corrective-action guidance for deep fat fryers under IEC 60335-2-13 / GB 4706.13, covering oil-temperature control, overflow and structure in full, and can assist with CCC, CE, UKCA and other certifications.

Putting testing up front is the most effective way to reduce tooling-change costs.
