Light-Transmitting Ability of Eye Protective Devices6.1 Clear Goggle or FaceshieldA “clear” goggle orfaceshield shall transmit not less than 80 % of the incidentvisible radiation.Agoggle or faceshield that
34、 transmits less than80 % of incident visible radiation shall be considered “tinted.”6.2 Ultraviolet and Infrared FiltrationUltraviolet andinfrared filtration shall meet the requirements of ANSI Z80.3for Special Purpose Lenses.6.3 Resistance to FoggingA goggle or faceshield that isdescribed as being
35、resistant to fogging shall pass the testspecified in Annex A1.NOTE 2To claim or describe a goggle or faceshield as being resistantto fogging is optional.7. Lens StrengthTest Methods7.1 Basic Impact Resistance Test:7.1.1 Significance and UseThis test method is intended toensure a basic level of prote
36、ction from impact on the surface ofa lens of a goggle or on the viewing portion of a faceshield. Itmay not be representative of all of the conditions of impactexperienced in snow skiing.7.1.2 ApparatusAn Alderson 50th percentile male head-form (see Fig. 1) shall be used to hold the goggle or faceshi
37、eld.It shall be rigidly mounted in the horizontal position, face up,on a base that has a mass of 30 kg (66 lb) or greater. The staticstiffness of the headform shall be such that, when a verticallydownward force of 20 kg (44 lb) is applied to the forehead ofthe headform, the back of the headform shal
38、l not deflect morethan 2 mm (0.08 in.). The missile for impacting the goggle orfaceshield shall be a polished steel ball, 22 mm (78 in.) nominaldiameter, and shall have a mass not less than 43 g (1.52 oz). Aloose-fitting guide tube shall be provided for the missile.7.1.3 ProcedurePlace the goggle or
39、 faceshield on theheadform as it would be worn by the user. Drop the ball in freefall from a height (measured from the bottom of the ball) of1.30 m (51 in.) above the exterior surface of the goggle orfaceshield. Impact the goggle or faceshield three times: onceabove the center of each eye of the hea
40、dform and once abovethe bridge of the nose of the headform. Test four representativesamples of the type of goggle or faceshield.7.1.4 Analysis of ResultsThe lens shall be retained in itsframe, and it shall not fracture into two or more pieces. If allfour samples pass the test, then the goggle or fac
41、eshield passes,but if any fail, then the goggle or faceshield fails.7.1.5 ReportFully identify the goggle or faceshield andrecord whether it passed or failed the basic impact test withspherical projectile. This report is for internal use by themanufacturer and is not included in statements for label
42、ing.7.1.6 Precision and BiasPrecision and bias information isnot applicable, because the results of the test are statedqualitatively and not as numerical values of physical quantities.7.2 Higher Impact Resistance Test:7.2.1 Significance and UseThis test method is intended toensure a level of protect
43、ion from relatively heavy, pointedobjects traveling at low speed. It may not be representative ofall of the conditions of impact experienced in snow skiing.7.2.2 ApparatusAn Alderson 50th percentile male head-form (see Fig. 1) shall be used to hold the goggle or faceshield.It shall be rigidly mounte
44、d in the horizontal position, face up,on a base that has a mass of 30 kg (66 lb) or greater. The staticstiffness of the headform shall be such that, when a verticallydownward force of 20 kg (44 lb) is applied to the forehead ofthe headform, the back of the headform shall not deflect morethan 2 mm (0
45、.08 in.). The missile shall have a 30 conical tipwitha1mm(0.04 in.) radius, shall have a mass of 500 g (17.6oz), and shall have a diameter of 25.4 mm (1 in.). The missileshall have a heat treated steel tip. A loose-fitting guide tubewith a smooth internal surface shall be provided for the missile.Th
46、is guide tube is to prevent the missile from tumbling andF659063also to protect the operator. Partial shielding of the headformmay be desirable to protect the feet of the operator.7.2.3 ProcedurePlace the goggle or faceshield on theheadform as it would be worn by the user. Hold the missileabove the
47、headform with its tip 130 cm (51 in.) above theexterior surface of the transparent portion of the goggle orfaceshield and aligned vertically above one eye of the head-form.Allow the missile to fall freely through 130 cm. Test fourrepresentative samples of the type of goggle or faceshield.7.2.4 Analy
48、sis of ResultsThe lens shall be retained in itsframe, and it shall not crack, fracture, nor be penetrated by thetip of the missile. If all four samples pass the test, then thegoggle or faceshield passes, but if any fail, then the goggle orfaceshield fails.7.2.5 ReportFully identify the goggle or fac
49、eshield andrecord whether it passed or failed the higher impact test withhigh mass, low velocity, pointed projectile. This report is forinternal use by the manufacturer and is not included instatements for labeling.7.2.6 Precision and BiasPrecision and bias information isnot applicable, because the results of the test are statedqualitatively and not as numerical values of physical quantities.8.
