Solar Umbrella: The Industry Standard Is Expressly Provided.

If you buy a parachute called "special ultraviolet protection", does the parachute have to block the sun's ultraviolet rays? Although the merchant's statement is varied, the most practical reminder is that if you sell a dozen twenty pieces of cheap umbrellas, you have to have a lot of mind if they also call themselves "ultra strong anti ultraviolet" and "double layer anti ultraviolet".

In the midsummer season, all kinds of umbrellas on the market sell well, ranging from 10 yuan to several hundred yuan, which are known as "special ultraviolet protection functions". Are there any unified standards? Consumers are really confused.

Yesterday, reporters asked several sales offices of umbrellas, most of them said that their anti UV umbrellas were coated with special coatings on their umbrellas, and sun protection index and sun protection level were basically marked on the sunshade umbrellas.

A businessman told reporters that most of the sunscreen umbrellas were coated with a layer of silver glue on the umbrella surface to block and reflect the direct ultraviolet radiation, but the quality of silver colloid was uneven.

Because the cost of sunscreen treatment for light weight cloth is higher, the selling price will usually be more than 100 yuan. Those cheap sunshade umbrellas that are not suitable for consumption are only coated with silver, and the sun will shine several times and the rain will be washed for a few times.

The staff of the Standardization Office of the Municipal Quality Supervision Bureau told reporters that the umbrella is currently in line with the industry standard and implemented in December 2007, which explicitly stipulates that if the sun umbrella is to protect against ultraviolet rays, it should be indicated and should comply with the relevant regulations of the national standard for the evaluation of the anti ultraviolet property of textiles.

How to determine whether the "UV protection" index is qualified? If it is in line with the express requirement of the sun umbrella, it is qualified, otherwise it will be unqualified.

In addition, every UV protection umbrella should be marked with grade.

The reporter has checked that the national standard "assessment of ultraviolet protection of textiles" stipulates that when the UPF (UV protection system value) is greater than 30, and the UVA (UVA) pmittance is less than 5%, it can be called "anti ultraviolet product", marked as "UPF30+". When UPF is greater than 50, it means that the UV protection performance is excellent, marked as "UPF50+".
