<p>This document specifies the reference test methods for determining the spherical, cylindrical, and prismatic refractive power properties of unmounted and mounted plano lenses (non-corrective lenses) for eye and face protectors.</p>
<p>This document does not apply to any eye and face protection product requirement standards for which other test methods are specified.</p>
<p>Other test methods can be used provided they have been shown to be equivalent and include uncertainties of measurement no greater than those required by the reference method.</p>
