Contact with the eye of the headform constitutes failure. Protective eyewear offers protection only to the eyes and does not protect other parts of the head. Eye protectors are classified into the following types: Types I, II, and III. Optical quality, luminous transmittance, prismatic deviation measurements, haze, refractive power measurements, surface imperfections and internal defects, and mechanical tests shall be performed to conform to the specified requirements.
Область применения1.1 This specification covers eye protectors with a plano (that is, non-prescription) lens or without a lens, designed for use by players of field hockey, that minimize or significantly reduce injury to the eye and adnexa due to impact by and penetration of field hockey balls and field hockey sticks. Contact with the eye of the headform constitutes failure. Protective eyewear offers protection only to the eyes and does not protect other parts of the head.
1.2 Testing is done in a laboratory setting. Eye contact is determined by observation.
1.3 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.
1.4 The following precautionary caveat pertains only to the test methods portion (Sections 8, 9, and 10) 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 and health practices and determine the applicability of regulatory limitations prior to use.
