2、ast revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers eye protectors, designed foruse by players of racket sports, womens lacrosse, field hockey,b

3、asketball, baseball, and soccer that minimize or significantlyreduce injury to the eye and adnexa due to impact andpenetration by racket-sport rackets and balls, womens lacrosseand field hockey sticks and balls, baseballs, soccer balls, hands,elbows, and fingers. Protective eyewear offers protection

4、 onlyto the eyes and does not protect other parts of the head.1.2 Protectors are divided into four types depending on theirdesign characteristics.1.3 This specification applies to eye protectors for use bywearers of corrective lenses and also by those players who donot require prescription eyewear.

5、(WarningPolycarbonatespectacle lenses should be used if spectacles are worn underprotective eyewear.)1.4 In this standard, the use of the words “shall” or “must”indicates a mandatory requirement. The word “should” indi-cates a recommendation.1.5 The values stated in SI units are to be regarded as th

6、estandard. The values given in parentheses are for informationonly. Metric units of measurement in this specification are inaccordance with the International System of Units (SI). If avalue for measurement as given in this specification is followedby an equivalent value in other units, the first sta

7、ted is to beregarded as the requirement. A given equivalent value may beapproximate.1.6 The following precautionary caveat pertains only to thetest methods portions, Sections 9-11, of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its

8、use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.
