UV Standard 801介绍
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。



Textiles and UV Protection (纺织品UV Standard 801)

Objective:
This test method is used to evaluate the UV protection factor, or UPF, of a textile which protects human skin from damaging UV rays. UV protective textiles are tested in the new condition as well as after an simulated use.


The test is particularly well-suited for:
•Textiles for swimming and/or beachwear, particularly for babies, toddlers and chil-dren
•Textiles used for sportswear, sporting equipment and leisure clothing
•Clothing for people who work in environments where they are exposed to UV radia-tion
•Shading textiles (e.g. parasols, awnings and sunshades)
•Other materials for sun protection (e.g. protective films)
Description:
Determination of UPF according to UV Standard 801 is based on the solar spectrum of the Australian standard. Samples are tested under different use conditions depending on the region in which the textile is to be used.
Garments are tested new and also after they have been subjected to the demands placed on them during use (stretching, wetting, abrading and washing).
In addition to being tested new, sun protection textiles are subjected to the demands placed on them during use (stretching, wetting, weathering).
The determined UPF is used as a multiplier for the duration of time an individual’s skin can protect itself from UV exposure, and indicates how long the textile allows the user to stay in the sun without incurring skin damage. According to UV Standard 801, the following levels of UV protection (UPF) can be achieved: 2, 5, 10, 15, 20, 30, 40, 60, 80.

Advantages for you as the customer:
•Consumer safety by UPF determination under use condition
•Proves product is effective
•Product optimization during development

Labels and certificates:
A UV Standard 801 certificate is required for promotion and product labeling. It is valid for 1 year.
Requirements for test samples:
General information:
•The customer specifies whether tests are to be carried for certification or not.
Amount of material:
•At least 60 cm x 80 cm
Duration of testing:
•15 working days
