UV Standard 801

   
      UV Standard 801是一份由应用紫外线保护国际检定协会发布的规范文件。 应用紫外线保护国际检定协会的会员为自己订立了目标，以厘定由实用产品所提供紫外线保护的程度，令在实践中施加于物料上的应变和应力亦在考虑之列。为达此目标，UV Standard 801已超越澳洲／新西兰标准（AS/NZS 4399:1996）及欧盟标准EN 13758-1 的要求，并已矫正其主要弱点。.

这项标准适用于所有平展的实用产品，例如纺织品、衣服、鞋类、遮篷、太阳伞、皮革、薄膜等等，均可保护人类免受紫外线幅射。在被检定的纺织品上，量度出紫外线幅射（UVA及UVB）的透射量，并厘定紫外线保护系数。例如在测试中, 纺织品会被洗涤, 磨擦, 而遮荫布則会经过适当的风化过程, 使变湿及延展后才作出正确的量度。

紫外保护因素(UPF)是说明用家穿着太阳或紫外防护衣物后能曝露于阳光下的最长时间而不致伤害皮肤。 紫外保护因素(UPF)与太阳或日光保护的防晒乳指数是相同的(SPF或LPF) 。

为了将UV Standard 801这标签附于制成品上, 一些有名的欧洲供應商已按照以上所提及的使用条件,将其产品认证。 认证范围由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.
