UVEEKAI is one of them: our entire collection is certified to UV STANDARD 801 by the Hohenstein Institute \u2014 not just selected items.<\/div><\/details><details><summary>What exactly does UV STANDARD 801 mean?<span class=\"pm\" aria-hidden=\"true\"><\/span><\/summary><div class=\"a\">Unlike a pure lab value, UV STANDARD 801 tests under real-world conditions: wet, stretched and after repeated washing. That way the UV protection holds up in everyday use \u2014 when swimming, sweating and after many washes. The German Federal Office for Radiation Protection describes the difference: AS\/NZS 4399 and EN 13758-1 measure only unstretched, dry textiles in mint condition, while UV STANDARD 801 also measures wet, stretched textiles \u2014 and only the lowest UV protection factor found during the entire test is declared (Source: <a href=\"https:\/\/www.bfs.de\/EN\/topics\/opt\/uv\/protection\/clothing\/clothing_node.html\" target=\"_blank\" rel=\"noopener\">German Federal Office for Radiation Protection (BfS)<\/a>).<\/div><\/details><details><summary>How can I recognise good UV protection clothing?<span class=\"pm\" aria-hidden=\"true\"><\/span><\/summary><div class=\"a\">Good UV protection clothing measurably keeps UV radiation off your skin, and that matters: according to the German Federal Office for Radiation Protection (BfS), UV radiation is the main cause of skin cancer. It can also trigger skin conditions such as so-called sun allergy (polymorphic light eruption). Look for two details: the UPF value and the test standard used to determine it. The BfS advises this too. EN 13758-1 and AS\/NZS 4399 measure new, dry, unstretched fabric. UV STANDARD 801 also measures the fabric wet and stretched, and only the lowest value from the entire test is declared. Colour or material alone tell you little; what matters most is how dense the fabric is. And check the cut: only the skin the fabric covers is protected. (Source: German Federal Office for Radiation Protection (BfS), 'UV protection through clothing', 'Long-term effects' and 'Acute skin damage')<\/div><\/details><details><summary>What is the difference between UPF and SPF?<span class=\"pm\" aria-hidden=\"true\"><\/span><\/summary><div class=\"a\">UPF and SPF are measured values. They show how strongly a form of protection reduces UV radiation, which helps you protect your skin in a targeted way. That matters because, according to the German Federal Office for Radiation Protection (BfS), UV radiation is the main cause of skin cancer, both non-melanoma (\u2018white\u2019) skin cancer and melanoma (\u2018black\u2019 skin cancer). It also ages the skin prematurely and can trigger skin conditions such as so-called sun allergy (polymorphic light eruption). Both values state by what factor the time until sunburn is extended. UPF (Ultraviolet Protection Factor) applies to textiles and is measured in the lab from how much UV the fabric lets through. SPF (sun protection factor) applies to sunscreen and, according to the BfS, describes protection against UVB; UVA protection is labelled separately. In practice there is one difference: SPF only applies if you use enough, and using half the amount can cut it by two thirds, says the BfS. With UPF, quantity plays no role.

UVEEKAI is one of them: our entire collection is certified to UV STANDARD 801 by the Hohenstein Institute \u2014 not just selected items.\"}},{\"@type\":\"Question\",\"name\":\"What exactly does UV STANDARD 801 mean?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Unlike a pure lab value, UV STANDARD 801 tests under real-world conditions: wet, stretched and after repeated washing. That way the UV protection holds up in everyday use \u2014 when swimming, sweating and after many washes. The German Federal Office for Radiation Protection describes the difference: AS\\\/NZS 4399 and EN 13758-1 measure only unstretched, dry textiles in mint condition, while UV STANDARD 801 also measures wet, stretched textiles \u2014 and only the lowest UV protection factor found during the entire test is declared (Source: German Federal Office for Radiation Protection (BfS)).\"}},{\"@type\":\"Question\",\"name\":\"How can I recognise good UV protection clothing?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Good UV protection clothing measurably keeps UV radiation off your skin, and that matters: according to the German Federal Office for Radiation Protection (BfS), UV radiation is the main cause of skin cancer. It can also trigger skin conditions such as so-called sun allergy (polymorphic light eruption). Look for two details: the UPF value and the test standard used to determine it. The BfS advises this too. EN 13758-1 and AS\\\/NZS 4399 measure new, dry, unstretched fabric. UV STANDARD 801 also measures the fabric wet and stretched, and only the lowest value from the entire test is declared. Colour or material alone tell you little; what matters most is how dense the fabric is. And check the cut: only the skin the fabric covers is protected.

They show how strongly a form of protection reduces UV radiation, which helps you protect your skin in a targeted way. That matters because, according to the German Federal Office for Radiation Protection (BfS), UV radiation is the main cause of skin cancer, both non-melanoma (\u2018white\u2019) skin cancer and melanoma (\u2018black\u2019 skin cancer). It also ages the skin prematurely and can trigger skin conditions such as so-called sun allergy (polymorphic light eruption). Both values state by what factor the time until sunburn is extended. UPF (Ultraviolet Protection Factor) applies to textiles and is measured in the lab from how much UV the fabric lets through. SPF (sun protection factor) applies to sunscreen and, according to the BfS, describes protection against UVB; UVA protection is labelled separately.
