TESTING CAPABILITIES

HIGH VELOCITY IMPACT

High impact glasses shall be capable of resisting impact from a 6.35 mm (25 caliber) diameter steel ball traveling at a velocity of 45.7m/s. No contact with the eye of the head form is permitted as a result of impact to be compliant with ANSI Z87.1+.

HEARING PROTECTION

All test equipment and test protocols are designed to be compliant with ANSI S3.19:1974 and tested in our dual wall acoustic chamber to reduce ambient noise below the hearing threshold.

HIGH MASS IMPACT

High impact glasses shall be capable of resisting an impact from a pointed projectile weighing 500 grams (17.6 oz) dropped from a height of 127 cm (50 inches) to be compliant with ANSI Z87.1+.

VO BALLISTIC PERFORMANCE

Vo Ballistic glasses shall be capable of resisting impact from 0.15 inch (15 caliber) diameter steel projectile traveling at a velocity of 195m/s to be compliant with Mil-PRF-31013.

DROP BALL IMPACT

Basic impact eyewear lenses shall be capable of resisting impact from a 25.4 mm (1 inch) diameter steel ball dropped from a height of 127 cm (50 inches) to be compliant with ANSI Z87.1+.

TESTING HEAD FORM

The 2003 Alderson head form has been replaced by the EN 168 European head form and is to be used for Prismatic Power, Drop ball Impact, Lateral Protection, High Mass Impact, High Velocity Impact and Penetration.
