纺织品UV Standard 801测试
UV Standard 801是国际紫外线防护应用测试协会制定的评定纺织品紫外线防护等级的认证标准，这个标准是在模拟实际穿着情况下，依据最强烈的UV射线及最敏感的皮肤类型做出的最严格的测试，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。

为提供给消费者可信的UPF指数，必须考虑防晒纺织品在使用中的特殊要求。纺织品在穿着过程中被拉伸的程度，受汗水、海水影响的湿润度，以及使用中的情况都会影响UPF。受上述条件影响，防护时间平均会降低三分之一，这些也必须反应在UPF指数(见下图)中以提示穿着者免受伤害。
作为应用紫外线保护国际检定协会的成员，推荐根据UV 801标准对各种纺织品进行UPF测试。UV 801标准是基于最恶劣的穿着情况来考虑，包括对纺织材料进行水洗和在湿润、拉伸的情况下进行测试。
进行UPF测试，使用的是最强烈的阳光，澳大利亚墨尔本1月1日的太阳光谱（即澳大利亚夏季的阳光）并且用最敏感的皮肤类型为基准依据。
对于澳大利亚-新西兰标准 (AS/NZS 4399:1996)，测试仅在新的纺织材料上进行，且其处于干燥、无拉伸的状态。 测试也是参照澳大利亚墨尔本1月1日的太阳光谱。
由于测试过程并未考虑服装穿着时的特殊环境，不可能计算出可信的服装防护指数，仅可作为室内外建筑用防晒纺织品、遮阳伞或遮阳篷防护指数的参考。
由于北半球的太阳光谱与澳大利亚的有所不同，欧洲标准 EN 13758-1采用的测试方法是基于美国新墨西哥州中部阿尔伯克基的太阳光谱，其与欧洲南部的太阳光谱有些相似。
AS/NZS4399：1996标准是采用新的纺织品在无拉伸、干燥的条件下计算UPF，这种测试方法也不完全适合服装产品，因为它忽视了人们正常的着装行为，而无法给出纺织品在使用条件下的可靠数值。

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
