【国外标准】 Standard Specification for Eye Protectors for Selected Sports

This specification covers eye protectors, designed for use by players of racket sports, women's lacrosse, field hockey, basketball, baseball, and soccer that minimize or significantly reduce injury to the eye and adnexa due to impact and penetration by racket-sport rackets and balls, women's lacrosse and field hockey sticks and balls, baseballs, soccer balls, hands, elbows, and fingers. Protective eyewear offers protection only to the eyes and does not protect other parts of the head. Protectors are divided into four types depending on their design characteristics as follows: Type I—A protector with the lens or lenses and frame frontpiece molded as one unit. Frame temples or other devices, such as straps, to affix the lens/frontpiece may be separate pieces; Type II—A protector with a single lens or lenses, either plano or prescription, mounted in a frame that was manufactured as a separate unit; Type III—A protector without a lens; and Type IV—A full or partial face shield. Materials shall be tested using optical tests such as field of view, optical quality, luminous transmittance, prismatic deviation measurements, haze, refractive power measurements, surface imperfections and internal defects, and alternate optical tests; and mechanical tests such as high velocity impact resistance, and projectile simulator test. In addition, the individual grades shall conform to the general, and performance requirements.1.1 This specification covers eye protectors, designed for use by players of basketball, baseball, and soccer to minimize or significantly reduce injury to the eye and adnexa due to impact and penetration by baseballs and softballs, basketballs, soccer balls, hands, elbows, and fingers. Protective eyewear offers protection only to the eyes and adnexa and does not protect other parts of the head.1.2 Protectors are divided into three types depending on their design characteristics.1.3 This specification applies to eye protectors for use by wearers of corrective lenses and also by those players who do not require prescription eyewear. (Warning—Polycarbonate or Trivex spectacle lenses should be used if spectacles are worn under protective eyewear.)1.4 In this standard, the use of the words “shall” or “must” indicates a mandatory requirement. The word “should” indicates a recommendation.1.5 Failure of the product occurs when the protector is unable to meet the general, mechanical, and optical (if applicable) requirements of the standard.1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. Metric units of measurement in this specification are in accordance with the International System of Units (SI). If a value for measurement as given in this specification is followed by an equivalent value in other units, the first stated is to be regarded as the requirement. A given equivalent value may be approximate.1.7 The following precautionary caveat pertains only to the test methods portions, Sections 9 – 11, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
