Wind quantity of rang hoods to undergo mandatory inspection BSMI, MOEA March 14, 2018

In response to the public’s concern about the suction power (wind quantity) of range hoods, the Bureau of Standards, Metrology & Inspection (BSMI) has announced on February 27, 2018 that “wind quantity” will be included on the list of items that must be inspected. Range hood products should be in compliance with the latest wind quantity requirements before being marketed.

In the past, it is believed that Taiwanese women have a lower chance of developing lung cancer and lung adenocarcinoma than their male counterparts because they smoke less. However, according to local media reports, recent medical studies found that the chances of Taiwanese female nonsmoker getting lung cancer are on the rise. Besides second hand smoking, kitchen exhaust is also cited as one of the pollutants. To ensure consumer rights, the BSMI has announced that wind quantity of range hoods will be included on the list of items that must be inspected.

The BSMI said that “wind quantity” is specified in Item 3.7 of CNS 3805 “Range Hood,” which sets the minimum standards for rand hood products (10m3/min for single blade and 11.6m3/min for double blades). The wind quantity specified on the body of the product, its packaging, labels or user’s manual must conform to the standards and the test results must not be lower than 95 of the labeled value. The revised standard will serve as a guideline for manufacturers to follow and a quality seal for consumers to easily identify.

The BSMI said that range hoods 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 range hoods, make a record and take legal actions. Consumer rights are ensured under this double-checking mechanism.

The BSMI said that manufacturers are responsible for product safety and correctness of labels. Meanwhile, consumers are urged to pay attention to the following precautions when purchasing range hoods.

1)Consumers are advised to purchase range hoods 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 and product specifications (voltage and power consumption) are clearly indicated. Choose a range hood that suits the size of the stove.
3)The range hood should be installed by professionals, who should install according to the user’s manual to ensure that the height and channels meet the exhaust requirements. Correct installation ensures the proper function of the range hood and prevents smoke from back-flowing.
4)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.
5)You can leave a small opening in the window. Do not do so if the window is opposite the range hood because air circulation could cause the smoke to spread before it is sucked into the hoods, reducing suction performance. Turn on the range hood immediately when you start cooking and turn off five minutes after you finish to get rid of hazardous smoke residues inside the kitchen.
6)Clean the filter and grease capture box even if the range hood is advertised as“wash-free”. Wipe and clean the exterior to prevent grease accumulation, which could cause rust, affect the sucking performance and reduce the life span of the range hood.
