4、 from IHS-Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agree

5、ment has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of Americ

Moreover, no person shall have the right or authority to issue aninterpretation of an American National Standard in the name of the AmericanNational Standards Institute. Requests f

14、ense with ANSINot for ResaleNo reproduction or networking permitted without license from IHS-iiForeword (This foreword is not part of American National Standard ANSI Z80.3-2001.)The purchasers and users of nonprescription sunglasses and fashion eyewear needto be assured of certain minimum levels of

15、performance and quality in these prod-ucts. These are either implicit expectations in the product performance or safety. Thepurchaser of the product does not ordinarily have the means to properly assessthese characteristics.In order to accomplish these goals, it is necessary to establish commonly ac

16、cepteddefinitions, equations, sources, and methodology so that manufacturers can produceproducts to meet the standard.This American National Standard specifies impact-resistant characteristics; cosmet-ic, refractive, and transmittance properties of lenses; and the flammability of framesand lenses.Co

17、smetic, refractive, transmittance, and frame properties specified herein are intend-ed as guidelines, and therefore they are subject to revision since there is a need tostudy further the validity of these property specifications as related to actual normaluse requirements.The Z80.3 Subcommittee was

18、organized in December 1970 and had its first meetingon January 7, 1971. The chairman was appointed by Dr. Arthur Keeney, chairman ofthe parent Z80 Committee. Other members were appointed jointly by Dr. Keeney andthe previous chairman of the subcommittee, John K. Davis.Suggestions for improvement of

19、this standard will be welcome. They should be sentto Optical Laboratories Association, PO.

29、AMERICAN NATIONAL STANDARD ANSI Z80.3-20011 American National Standard for Ophthalmics Nonprescription Sunglasses and Fashion Eyewear Requirements 1 Scope and purpose 1.1 Scope This standard applies to all nonprescription sunglasses and fashion eyewear, normally used for casual, dress, and recreatio

30、nal purposes, having lenses of substantially plano power. This standard specifically excludes products covered by ANSI Z87.1-1989 (R1998), ANSI Z80.1-1999, ANSI/ASTM F803-01a and high-impact-resistance eyewear designed exclusively for designated sports use. Sunglass needs for aphakics may not be met

31、 by this standard. 1.2 Purpose The purpose of this standard is to establish standards for noncorrective (essentially plano power) lenses that are intended for attenuation of light and for fashionwear, and the flammability of frames and lenses. These products are commonly called sunglasses and are no

32、t designed to be industrial safety eyewear as defined in ANSI Z87.1-1989 (R1998), or to provide corrective prescriptions as defined in ANSI Z80.1-1999, or to provide protection for selected sports defined in ANSI/ASTM F803-01a. Lenses covered by this standard are not intended for use under condition

33、s of reduced illumination, such as for night driving. 2 References The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid. All standards are subject to r

39、finitions 3.1 Capable of withstanding an impact test: Capable of withstanding an impact test means able to withstand impact as determined by 100% testing or by testing of a statistically significant sample (for example, conforming to the requirements of ANSI/ASQC Z1.4-1993) of each production batch

40、at the option of the manufacturer as an integral part of the manufacturing process. Capability of withstanding an impact test is determined by testing at any feasible stage of manufacture described in 5.1.1 and 5.1.2. 3.2 Density: Density (also called optical density) is the logarithm to the base 10

41、 of the reciprocal of transmittance (Density = log 1/ ). 3.3 Geometric center: The geometric center is the point midway between the two vertical tangents and midway between the two horizontal tangents of the edges of a lens. 3.4 Lens fracture: A lens is considered to have fractured when it cracks through its entire thickness and across a complete diameter into two or more separate pieces, or when any piece of lens material, visible to the naked eye, becomes detached fro
