5、ndard was published by BSI and came into effect on 29 September 2006. It was prepared by Technical Committee TCI/66, Apparel. A list of organizations represented on this committee can be obtained on request to its secretary.Information about this documentInternational research has shown that prolong

6、ed exposure of the skin to the sun can produce both short and long term harm to the individual. Hats are an important part of protection from solar ultraviolet radiation (UVR) in shielding the head, neck, face and eyes from direct sunlight. Unlike clothing, the exposed areas of the face, neck and ey

7、es can be exposed to reflected light from the surroundings. Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general informati

8、ve material is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British Standa

9、rd cannot confer immunity from legal obligations. BSI 2006 1BS 8466:20061 ScopeThis British Standard specifies minimum ultraviolet transmission requirements for materials used in the construction of hats worn to give some protection from solar ultraviolet radiation. Requirements for dimensions, desi

10、gn and labelling are also included in the standard. NOTE Babies up to six months are not adequately protected by hats and should be fully shielded from the sun by other suitable means.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

BSI 2006 7BS 8466:2006Annex A (normative) Test methodA.1 PrincipleThe UPF is determined from the total spectral transmittance a

29、s described in BS EN 13758-1:2002, Clause 4.A.2 ApparatusA.2.1 Spectrophotometer, as specified in BS EN 13758-1:2002, 5.1 to 5.5.A.3 ConditioningBefore testing, condition the fabric or hat for a minimum of 24 h in a standard atmosphere of (20 2)C and (65 2)% r.h. as specified in BS EN ISO 139. If th

30、e spectrophotometer is not located in the conditioning area, complete the testing within 10 min of removing the sample. A.4 PreparationPrepare specimens in accordance with BS EN 13758-1:2002, 6.1.Prepare the specimen areas to be tested so that they can be placed across the entrance port of the integ

31、rating sphere in a flat tensionless state without distortion. If necessary, cut the specimens from the hat ensuring that, in multilayer construction, the sample is presented to the apparatus in the same order as the made up hat. A.5 Measurement of UV transmissionCalibrate the spectrophotometer as sp

32、ecified by the manufacturer. Place the specimen over the transmission port with the UV transmitting filter between the specimen and the port and the inside (as worn) of the sample towards the inside of the integrating sphere. Measure and record the transmission between 290 nm and 400 nm at intervals

33、 5 nm or less. Turn the sample through 90 and repeat the measurement. Test the remaining three specimens in the same way.A.6 Calculation and expression of resultsCalculations and expression of results shall be as specified in BS EN 13758-1:2002, 8.1 and 8.2.BSI British Standards InstitutionBSI is th
