UV Standard 801是一份由應(yīng)用紫外線保護國際檢定協(xié)會發(fā)布的規(guī)范文件。 應(yīng)用紫外線保護國際檢定協(xié)會的會員為自己訂立了目標，以厘定由實用產(chǎn)品所提供紫外線保護的程度，令在實踐中施加于物料上的應(yīng)變和應(yīng)力亦在考慮之列。為達此目標，UV Standard 801已超越澳洲／新西蘭標準（AS/NZS 4399:1996）及歐盟標準EN 13758-1 的要求，并已矯正其主要弱點。.

這項標準適用于所有平展的實用產(chǎn)品，例如紡織品、衣服、鞋類、遮篷、太陽傘、皮革、薄膜等等，均可保護人類免受紫外線幅射。在被檢定的紡織品上，量度出紫外線幅射（UVA及UVB）的透射量，并厘定紫外線保護系數(shù)。例如在測試中, 紡織品會被洗滌, 磨擦, 而遮蔭布則會經(jīng)過適當?shù)娘L(fēng)化過程, 使變濕及延展后才作出正確的量度。

紫外保護因素(UPF)是說明用家穿著太陽或紫外防護衣物后能曝露于陽光下的最長時間而不致傷害皮膚。 紫外保護因素(UPF)與太陽或日光保護的防曬乳指數(shù)是相同的(SPF或LPF) 。

為了將UV Standard 801這標簽附于制成品上, 一些有名的歐洲供應(yīng)商已按照以上所提及的使用條件,將其產(chǎn)品認證。 認證范圍由UPF 5 至80不等。

UV Standard 801 is a normative document issued by the International Testing Association for Applied UV Protection. The member institutes of the International Testing Association for Applied UV Protection have set themselves the objective of determining the UV protection provided by a functional product in such a way that the strains and stresses imposed on the material in practice are taken into account. With this objective UV Standard 801 goes far beyond the requirements of the Australia/New Zealand Standard (AS/NZS 4399:1996) and of the European standard EN 13758-1 and remedies their principal weaknesses. This standard is applicable to all flat functional products, such as textiles, clothing, shoes, awnings, sunshades, leather, films, etc., which can in any way protect human beings against UV radiation. The transmission of UV radiation(UVA and UVB) is measured and the UV Protection Factor determined on the textiles being tested. For example, in the course of testing, clothing textiles are washed and abraded, and shading textiles are appropriately exposed to weathering, as well as be-ing moistened and stretched in a defined manner for measurement.

The UV Protection Factor (UPF) indicates how much longer the user of sun-protective textiles or the wearer of UV-protective clothing can remain in the sun without suffering skin damage. The UV Protection Factor UPF is identical to the sun or light-protection factor of sun creams (SPF or LPF).

The leading European suppliers have their products tested in conformity with UV Standard 801 under the above-mentioned conditions of use in order to attach the UV Standard 801 label to the made-up functional product. Certifications ranging from UPF 5 to 80 are used here.
