To the winter season, can be in the hands of a heating Hand beloved treasure for many people, especially the flexible electric Nuanshou (contents of a liquid, packaging materials for the soft texture of Hand heaters) because of great variety, very popular and easy to carry. In yiwu international trade City, a wide variety of Hand dazzling treasure, a metal casing, the pocket as well as ceramics, are of various shapes, and some can be hung around the waist. However, many products only power supply voltage, size, power, charging time, heat time, such as identification, and for important safety indicators but no label, consumers have not paid enough attention.

It is understood that AQSIQ issued a "household and similar electrical appliances electric thermal storage Particular requirements for Hand" was formally implemented on 1 day, that safety standard has been Hand Po by. Under this standard, electric heating to warm bag of 80 kg weight placed on the surface of 5 minutes will not occur in the liquid leakage or rupture, that is, an adult should be able to withstand the weight of up to 5 minutes. In addition, Hand Po will have some heated internal air pressure, air pressure is too high may cause the product to burst, the internal liquid flow may be hazardous in the human body, there should also be standards for electric heaters to prevent excessive internal pressure protection device.

But both businesses and consumers, the standards currently know little about. Only some of the goods market position on the packaging clearly marked "not suitable for children," the words inside the box by a certificate and a more detailed safety instructions. Hand Po will be in direct contact with the body, so the national standard for the safety of products made clear stipulations, such as indoor temperature is 0 ℃, then the electric heating bag after the warm surface temperature may not exceed 75 ℃. Therefore, when consumers buy Hand Po to establish a safety awareness, look for signs and related 3C safety certification.
