Current through Register Vol. 50, No. 9, September 20, 2024

Section III-1125 - Lens Strength-Testing Procedure for Eye Protection Devices

A. Helmet mounted face shields shall be tested while attached to a helmet and mounted on a human head form as herein defined. An EPD not designed to be attached to a helmet shall be tested on the same type of head form and shall be located in a position simulating its position in actual use.

B. The human head form used for testing both the helmet mounted face shield and the other EPD's herein defined shall be an "Anthropomorphic Head Assembly SA 150 M010" as defined in the National Highway Traffic Safety Administration's Standard 572, "Anthropomorphic Test Dummies". The head form needs to have only those features necessary to test EPD's which shall include size, facial features, and covering material.

C. A steel projectile 3/8" in diameter, weighing 1.56 ounces, approximately 2 1/2" long with a conical point of 90 degree included angle, the point having a spherical radius no greater than 0.020" and a hardness of 60 (+10) on the Rockwell C scale, shall be freely dropped from a height of 14 feet above the EPD. The projectile may be guided, but not restricted, in its vertical fall by dropping it through a tube extending to within approximately 4" of the impact area. The impact area must be on the forward optical surface and within a 1" diameter circle centered over the eye opening. The impact point shall be perpendicular to a plane tangent to the impact area.

D. Cracking and piercing of the EPD is permissible provided that the projectile does not pass through or remain lodged in the lens, but is repulsed by the EPD. No lens shall become dislodged nor shall any particles of the EPD break loose from any eyeward surface of the EPD.

E. Tests shall be performed at EPD temperatures of 0° and 110°F. Tests shall be performed at 10 percent and 90 percent relative humidities for all temperatures in excess 70°F. The EPD shall be conditioned in the specified environment for a minimum of four hours, removed, and tested within five seconds.
