BSMI and Consumers’ Foundation publish induction stove inspection results BSMI, MOEA February 13, 2018

Induction stove is a common home cooking appliance because cooking with it is a faster and more convenient process. To ensure consumer rights and to look into the safety of induction stove products, the Bureau of Standards, Metrology & Inspection (BSMI) and the Consumers’ Foundation, Chinese Taipei initiated an induction stove inspection in 2017. Of the ten items bought from department stores, electronic shops and retail shops, one did not meet the quality standards and another failed the “key component matching” requirements. However, all items are in conformity with the commodity inspection mark and “Chinese labeling” requirements.

Inspection standards
The BSMI said that the inspection is based on three national standards: CNS 3765 “Household and similar electrical appliances—Safety—Part 1: General requirements,” CNS 13803 “Limits and methods of measurement of electromagnetic interference characteristics of industrial, scientific and medical (ISM) radio-frequency equipment,” CNS 14978 “Household and similar electrical appliances—Electromagnetic fields—Methods for evaluation and measurement” and IEC 60335-2-9 “Household and similar electrical appliances—Safety—Part 2-9: Particular requirements for grills, toasters and similar portable cooking appliances.

Six quality tests were conducted, including “temperature rise test,” “insulation resistance and electrical strength,” “abnormal operation test,” “structure inspection,” “electromagnetic compatibility” and “low frequency electromagnetic field.” “Key component matching” as well as “commodity inspection mark” and “Chinese labeling” requirements were also inspected.

Inspection results
The inspection results of the sample items are as follows.
1)Quality test:
1.1 All passed the “temperature rise test,” “insulation resistance and electrical strength,”“structure inspection,”“electromagnetic compatibility”and“low frequency electromagnetic field”inspections.
1.2 One item (number 10) failed the“abnormal operation test”. The induction stove is first connected to an electrical supply with rated voltage and operated according to instruction. When the temperature control device is tempered to malfunctions, the oil temperature rose to 327.2 Celsius. Under such circumstances, the temperature must not rise above 295 Celsius.
2)Key component matching: One item (number 4) failed the inspection because its front exterior and printed circuit board layout were not in consistent with the submitted application information.
3)Labeling:
3.1 All passed the“commodity inspection mark”inspection.
3.2 All passed the“Chinese labeling” inspection.

Follow-up procedures
1)With regard to the item that failed the quality tests, its type approval will be revoked according to Article 16 of the Regulation Governing Type Approval of Commodities. If the vendor concerned failed to recall or correct the product within a given time limit, a fine between 100,000 NTD and 1,000,000 NTD will be imposed according to Article 63-1 of the Commodity Inspection Act.
2)With regard to the item that failed key component matching inspection, as only some parts were not in consistent with the submitted application information and that the design of the product remain unchanged, the vendor concerned will be notified to submit another application for approval according to Article 40 of the Commodity Inspection Act.

The BSMI said that induction stoves are subject to mandatory inspection before being dispatched from the factory or imported. The BSMI has an annual market inspection scheme to counter marketed products that are not in conformity with national standards. Inspectors will be dispatched to look into under qualified induction stoves, make a record and take legal actions. Consumer rights are ensured under this double-checking mechanism.

Precautions when purchasing LED light bulbs
The BSMI said that manufacturers are responsible for product safety and correctness of labels. Consumers are also urged to pay attention to the following precautions when purchasing induction stoves.
1)Consumers are advised to purchase induction stoves that have a commodity inspection mark (markormark).For inquiries, please refer to https://civil.bsmi.gov.tw/bsmi_pqn/do/pqn5860/form
2)Make sure that the name of the manufacturer, its registered address, power specifications (voltage, power consumption or current) and model are clearly indicated.
3)Make sure that the product comes with a Chinese instruction booklet, a label of instruction and a warning label. Read carefully before use, follow the instruction and pay attention to warnings.
4)As induction stoves is a high energy consumption product, do not share its socket with other appliances. When using an extension cord, first check the power consumption of the induction stove (wattage) and make sure that it does not exceed the power capacity limit of the extension cord. Insufficient power capacity can lead to cord overheating, insulation damage, short circuit and fire.
5)When using the induction stove, place it horizontally and steadily on a flat surface in a room with no inflammables. Make sure that cookware do not fall on the stove and cause accidents.
6)When using the induction stove, stay away from water or wet environment to prevent damp damage to the parts or risks of short circuit.
7)Do not place watches, credit cards, bank cards, magnetic cards and objects with magnetic properties next to the induction stove. As the stove heats a cooking vessel by magnetic induction, the magnetic wave could cause demagnetization of magnetic objects.
8)Before using the induction stove, make sure that the cable is fully plugged and not loosely plugged. When unplugging, hold and pull the power plug and not the cable to prevent damage to the copper wire.
9)Should the induction stove malfunctions, stop from use immediately and contact the manufacturer’s designated repair station. Do not change the parts or disassemble by yourself. Regular maintenance is necessary to ensure safety.

The BSMI reminds consumers that more knowledge you have about the products you are buying means more safety. For more information, please visit the BSMI Product Safety Internet at https://safety.bsmi.gov.tw or call the toll free number of 0800-007123.
