Umbrella test UPF and UVA index
Umbrella Test: On the label of the umbrella, there are two important indexes. One is UPF (UV protection factor value) and the other is UVA (long-wave UV transmittance). According to the National Standard for National Umbrella, the UPF value must be greater than 40, while the UVA should be less than 5%. The smaller the UVA index, the better the UV protection effect. “The two values must be marked on the label of the umbrella. It is indispensable. If there is no umbrella marked or marked with an index that is not up to standard, it cannot be sold as an umbrella.
Umbrella Test: During the inspection, the consumer volunteers found that some brands had false labels. For example, it is clear that there is no UV protection function, but it is marked with the words “hot silver sunscreen” and “black di sunscreen”. In addition, the Chinese label must be on the umbrella label, and the label without the Chinese label is also unqualified.
Umbrella Test: When consumers choose a sunny umbrella, they must first look at the label, and whether the two values of UPF and UVA are marked at the same time, and whether the value conforms to the national regulations. Then choose the umbrella of black, navy, dark green light blue, light pink, light yellow and so on. Finally, open the umbrella and see if the umbrella is full. Don’t put it in a “basin dish” or “deep bowl shape”. Whether the rib is rusty or not, whether it is flexible or not.
